Description
BACKGROUND OF THE INVENTION
The present invention relates to a method for system obstacle correspondence
support in an information processing system constituted by a plurality of information
processing units. In the method, when an error message outputted by an information
processing unit is received, a command is generated and transmitted in accordance
with a method corresponding to the error message.
Conventionally, an information processing unit is provided with a
console unit for managing interface between an operator and the information processing unit.
A message showing the operating state of the information processing unit is displayed
on the console unit.
The message includes an error message showing error information of the information
processing unit.
The operator inputs an appropriate command through the console unit in response
to the error message so as to deal with an error.
JP-A-10-312321 discloses a method for supporting such input of a command
corresponding to an error message.
According to the method disclosed in JP-A-10-312321, the following method
is adopted and intended for a single on-line system. That is, messages outputted
every fixed time unit before errors occurred, and operating states of hardware
and software constituting the on-line system at the point of time when the errors
occurred, are accumulated as cases together with error information and correspondence
methods corresponding to the errors; and
when an error occurs, error information generated with the error, messages accumulated
until the error occurs, and operating states of the hardware and the software at
the point of time when the error occurred, are compared with the respective pieces
of information accumulated as cases, and a correspondence method for a case having
most agreed information with the error is set as a correspondence method to the
occurring error.
In addition, in each correspondence method, a correspondence command and a command
for confirming the execution result of the correspondence command are defined for
one case.
However, in an information processing system constituted by a plurality
of information processing units, an error message may occur in one information
processing unit because of an event occurring in another information processing unit.
In such a case, an operator has to investigate the cause of the error message
from messages of the respective information processing units, and input a command
corresponding to the cause.
Moreover, a plurality of commands may be inputted for one error message.
In this case, a command to be inputted next may be determined on the basis of an
execution result of a command inputted previously.
According to the method disclosed in JP-A-10-312321, in the case of an
error message occurring in one information processing unit because of an event
occurring in another information processing unit in an information processing system
constituted by a plurality of information processing units, a command cannot be
transmitted to the information processing unit in which the event occurred.
In addition, according to the method disclosed in JP-A-10-312321, a plurality
of commands cannot be inputted for one error message on the basis of execution
results on the respective commands.
An object of the present invention is to acquire, from all the information processing
units, messages required for investigation of the cause of an error message occurring
in one information processing unit in an information processing system constituted
by a plurality of information processing units.
Another object of the present invention is to accumulate information in which
messages acquired for investigation of a cause of an error message occurring in
an information processing unit are made to correspond to a command inputted to
deal with an error in an information processing system constituted by a plurality
of information processing units, search the accumulated information when a similar
event occurs, and explicitly address an obstacle correspondence method to an operator.
A further object of the present invention is to generate, from the accumulated
information, a command for dealing with the error message, select an information
processing unit as a transmission place of the command, and transmit the command
to the information processing unit.
A still further object of the present invention is to accumulate information
in
which messages acquired for investigation of a cause of an error message occurring
in an information processing unit are made to correspond to an execution order
and execution conditions of a plurality of commands inputted to deal with an error
in an information processing system constituted by a plurality of information processing
units, search the accumulated information when a similar event occurs, and execute
the commands in accordance with the execution order and the execution conditions
of the commands.
In order to achieve the above objects, according to the present invention, there
is provided a method for system obstacle correspondence support in a console system
having a control unit including a display unit, an input unit, means for acquiring
messages from at least one information processing unit, storage means for storing
the acquired messages, and a storage unit for storing data for supporting correspondence
to an error message indicating an error and acquired from the information processing
unit, wherein first data for identifying the error message and second data for
identifying a related message related to the error message are included in a part
of the data in the storage unit, and a character string constituting the error
message is defined as a part of the first data, while a character string constituting
a message to be searched as the related message is defined as a part of the second
data; and wherein when the character string of the first data is included in an
error message acquired from the information processing unit, the second data is
selected, a message including the character string of the selected second data
is searched from the storage means, and the searched message is set as a related
message to the error message.
Further, preferably, a value of the character string constituting the error
message and a position of the value of the character string in the error message
are defined as a part of the first data, while a value of a character string constituting
a message to be searched as the related message and a position of the character
string are defined as a part of the second data; the second data is selected when
the value of the character string defined in the first data is included in the
position of the character string defined in the first data in an error message
acquired from the information processing unit; a message in which the value of
the character string defined in the second data is included in the position of
the character string defined in the second data is searched from the storage means;
and the searched message is set as a related message to the error message.
Further, preferably, third data in which the first data is associated with
the second data used for searching the related message is accumulated in the storage
unit; and when a command inputted from the input unit for an error message and
a related message in agreement with the third data includes a character string
constituting the error message, the related message, or a reply message to a command
inputted previously, a command format in which a portion of the character string
included in the command is replaced by information indicating a position of the
character string of the error message, the related message or the reply message
is accumulated as fourth data in the storage unit.
Further, preferably, when a plurality of commands are inputted for an error
message and a related message in agreement with the third data, third data to which
information for identifying a reply message to a command inputted previously is
added, and fourth data indicating a command following the previously inputted command
are accumulated in the storage unit.
Further, preferably, when the error message and the related message to the
error message are in agreement with the third data, all of the fourth data corresponding
to the third data are selected as correspondence methods to the error message and
the related message; and the fourth data selected as the correspondence methods
are displayed on the display unit.
Further, preferably, when the third data in which information for identifying
the third data used for selecting the fourth data is included as identification
information is present, the fourth data corresponding to the third data having
the identification information is selected as a correspondence method to be carried
out next to the fourth data; and the fourth data selected as the correspondence
methods are displayed on the display unit in accordance with an order with which
the correspondence method are to be carried out.
Further, preferably, for a portion of information included in an error message
or a related message for which correspondence methods are to be generated or in
a reply message to a command carried out previously, which information indicates
a position of a specific character string in the error message, the related message
or the reply message, a character string in a position designated by the information
indicating the position of the error message, the related message or the reply
message is substituted to generate a command in accordance with the command format
of the fourth data corresponding to a correspondence method displayed on the display
unit and selected by the input unit; and an information processing unit to which
the generated command is to be transmitted is selected on the basis of information
designating a transmission place of a command in the fourth data, and the generated
command is transmitted to the selected information processing unit.
Further, preferably, when a correspondence method to be carried out next
is present after the command is carried out, the correspondence method to be carried
out next is carried out if a reply message to the command is in agreement with
information for identifying a reply message to the command in the third data.

in the control unit
100.
The obstacle correspondence support program is constituted by the following processing portions.
(1) communication processes 11, 12 and 13
(2) a process 14 for searching a related message
(3) a process 15 for generating recovery operation information
(4) a process 16 for searching recovery operation information
(5) an input-and-output process 17
(6) a process 18 for generating commands
In the communication processing programs
11,
12 and
13,
messages
or commands are exchanged with the information processing units
1,
2
and
3 through the lines L
1, L
2 and L
3.
For example, the communication processes
11,
12 and
13 correspond
to the information processing units
1,
2 and
3 respectively.
In the communication
11,
12 and
13, all the messages acquired
from the information processing units are stored in the file
19 of message
log information.
Incidentally, the number of information processing units is not limited
in the present invention.
In the process
14 for searching a related message, a message related to
an error message received from an information processing unit is searched from
the file
19 of message log information with reference to the file
20
of information for searching messages.
In the process
15 for generating recovery operation information, information
of a command inputted from the keyboard
23 for the error message and the
related message searched in the related message searching process is stored in
the file
21 of recovery operation information.
In the process
16 for searching recovery operation information, information
of a command for dealing with the error message and the related message is searched
from the file
21 of recovery operation information.
In the input-and-output process
17, messages received from the information
processing units
1,
2 and
3, error messages, related messages,
and information of commands searched in the process
16 for searching recovery
operation information, are displayed on the display unit
22, and input information
is acquired from the keyboard
23 or the mouse
24.
In the input-and-output process
17, execution instructions are sent to
the communication processes
11,
12 and
13, the process
15
for generating recovery operation information, the process
16 for searching
recovery operation information, and the process
18 for generating commands,
in accordance with the contents of the acquired input information.
In the process
18 for generating commands, commands are generated on the
basis of the information of commands searched in the process
16 for searching
recovery operation information.
Next, the summaries of the respective processes will be described.
FIG. 2 shows briefly the process
14 for searching a related message and
the process
15 for generating recovery operation information.
Incidentally, only one communication process (communication process
11) is shown in FIG. 2 for convenience's sake.
The process
14 for searching a related message analyzes an error message
received from the communication process
11 (
14a).
Next, on the basis of the analyzed information, information for searching a
related message to the error message is acquired from the file
20 of information
for searching messages, and a message in agreement with the acquired information
is searched from the file
19 of message log information, and outputted as
a related message
30 (
14b).
The related message
30 is displayed on the display unit
22 in the
input-and-output process
17.
Incidentally, the file
19 of message log information stores
all the messages acquired from the information processing unit in the communication
process
11.
In the process
15 for generating recovery operation information, the related
message
30 is analyzed (
15a).
Next, a condition for searching recovery operation information is generated
on the basis of the information obtained by the analysis of the related message
and the information in the message searching information file
20 used in
the process for searching a related message (
15b).
Next, a command inputted from the keyboard
23 is received from the input-and-output
process
17, and the received command is analyzed (
15c).
Contents of recovery operation are generated on the basis of the information
obtained by the analysis of the command, associated with the recovery operation
condition generated in the step
15b, and stored in the file
21
of recovery operation information (
15d).
When a plurality of commands are inputted for the error message and the related
message, the above-mentioned processing is carried out on the first one of the commands.
The method for generating a recovery operation condition in the step
15b
for the second command et seq. differs from that for the first command.
Specifically, a reply message which shows the result of execution of
a command inputted previously is analyzed (
15a), and the information
obtained by the analysis of the reply message and the recovery operation condition
for the command inputted previously are combined to generate a recovery operation
condition (
15b).
While the information stored in the file
21 of recovery operation information
is displayed on the display unit
22, the displayed contents may be edited
by the keyboard
23 or the mouse
24 so that the information stored
in the file
21 of recovery operation information can be changed in accordance
with the edited contents (
15e).
FIG. 3 shows briefly processing in the process
16 for searching recovery
operation information and in the process
18 for generating commands.
Incidentally, in FIG. 3, only one communication process (communication
process
11) is shown for convenience's sake.
In the process
16 for searching recovery operation information, the error
message
31 and the related message
30 searched in the process
14
for searching a related message are analyzed (
16a).
Next, information whose recovery operation condition is in agreement with the
analyzed information is searched from the file
21 of recovery operation
information (
16b). The contents of the searched information are displayed
on the display unit
22 in the input-and-output process
17.
In the process
18 for generating commands, a command is generated on the
basis of the contents of recovery operation corresponding to a recovery operation
method selected by the keyboard
23 or the mouse
24, and a result
32 of the analysis of the error message
31 and the related message
30 in the process
16 for searching recovery operation information.
The generated command is transmitted to the information processing unit in the
communication process
11.
When there is a command to be executed next to the transmitted command, a reply
message which is a result of execution of the transmitted command is analyzed (
16a).
In the process
18 for generating commands, commands are generated on the
basis of the recovery operation information, and the result of the analysis of
the error message, the related message and the reply message.
Next, description will be made about various pieces of information stored in
the file
19 of message log information, the file
20 of information
for searching messages, and the file
21 of recovery operation information,
which are used in the respective processes.
FIG. 4 shows a format of message records
40 stored in the file
19
of message log information.
The message record format is constituted by a time
41 when a message was
generated, a system name
42 of an information processing unit which outputted
the message, and the generated message
43.
A record
40a shows a message "JDJ1234 J123 AAA BBB CCC" generated
in the information processing unit CPU-A at 10:05:15.
FIG. 5 shows a format of records
50 of information for searching related
messages, which are stored in the file
20 of information for searching messages.
Each of the records
50 of information for searching related messages
is constituted by a selection condition
51 and a condition
52 for
searching a related message.
The selection condition
51 is a condition for identifying an error message
using the condition
52 for searching a related message.
That is, when an error message is in agreement with the selection condition
51, a related message is searched by use of the condition
52 for
searching a related message.
In the selection condition
51, positions and values of WORDs constituting
an error message as a target are set in the form of "WORDn=value of WORD".
In a record
50a, an error message whose third WORD is "JSF621D",
whose fourth WORD is "m", and whose fifth WORD is "VOLUME", is set as a target.
The condition
52 for searching a related message defines the condition
of a message to be searched as a related message.
A plurality of conditions can be defined in the condition
52. Each condition
is defined as SELn.
Each condition is defined by designating a keyword shown in FIG. 6.
WORDn is defined in the form of "WORDn=character string" or "WORDn=WORDm".
"WORDn=character string" means that a message is detected if the
value of the n-th WORD of the message is in agreement with the designated character string.
"WORDn=WORDm" means that a message is detected if the value of the
n-th WORD of the message is in agreement with the value of the m-th WORD of the
error message.
INCLUDE is defined in the form of "INCLUDE=character string" or "INCLUDE=WORDn".
"INCLUDE=character string" means that a message is detected if
the message includes the character string.
"INCLUDE=WORDn" means that a message is detected if the message includes
the value of the n-th WORD of the error message.
TIME is defined in the form of "TIME=n".
"TIME=n" means that messages generated n seconds before occurrence of the
error message are set as messages to be searched.
SYSTEM is defined in the form of "SYSTEM=system name". "SYSTEM=system name"
means that a related message is searched from messages generated in an information
processing unit designated by the system name.
The condition
52 for searching a related message is defined using the
above-mentioned keywords.
In the record
50a in FIG. 5, n searching conditions are defined.
A first condition SEL
1 shows that a message whose first WORD is JDJ1234
and whose second WORD is in agreement with the value of the first WORD of the error
message is detected.
A second condition SEL
2 shows that a message whose first WORD is JDD5678
and whose second WORD is in agreement with the value of the 11th WORD of the error
message is detected.
An n-th condition SELn shows that a message which includes the value of the first
WORD and the value of the 11th WORD of the error message is detected.
FIG. 7 is a diagram showing a format of records
60 of error message selection
condition, a format of records
70 of message selection condition, a format
of records
80 of command format and a format of records
90 of recovery
operation information, these records
60,
70,
80 and
90
being stored in the file
21 of recovery operation information.
The records
60 of error message selection condition store information
for selecting error messages using the records
90 of recovery operation
information. Each record
60 is constituted by an ID
61 and a selection
condition
62.
The ID
61 is an ID for identifying the record.
The contents of the selection condition
62 are the same as those of the
selection condition
51 of the record
50 of information for searching
a related message.
The records
70 of message selection condition store information for selecting
related messages or reply messages using the records
90 of recovery operation
information. Each record
70 is constituted by an ID
71 and a condition
72.
The ID
71 is an ID for identifying the record.
The condition
72 defines a condition for a related message or a reply message.
A plurality of conditions can be defined in the condition
72. Each condition
is defined as SELn.
Each condition is defined by designating EWORDn, RmWORDn and ClSmWORDn of the
keywords shown in FIG. 8.
EWORDn shows the value of the n-th WORD of the error message.
RmWORDn shows the value of the n-th WORD of a related message in agreement
with the condition of SELm of the record
70 of message selection condition.
ClSmWORDn shows the value of the n-th WORD of a reply message to the l-th
command transmitted for an error, which value is in agreement with the condition
of SELm of the record
70 of message selection condition.
In a record
70b, a message satisfying the following two conditions
is selected.
(1) The value of the first WORD is in agreement with the value of the first
WORD of the error message.
(2) The value of the second WORD is "STOP".
The records
80 of command format store formats of commands to transmit
to the information processing unit. Each record
80 is constituted by an
ID
81 and a command format
82.
The ID
81 is an ID for identifying the record. The command format
82
is a format of a command to be transmitted to the information processing unit.
Incidentally, in the command format, a character string including WORDn
may be designated. Then, WORDn is substituted for a character string designated
in the record
90 of recovery operation information.
The records
90 of recovery operation information store contents of recovery
operation for error messages.
Each record
90 of recovery operation information is constituted by an
ID
91, a condition ID
92, a CMD-ID
93, setting information
94, a transmission place
95, and a display name
96.
The ID
91 is an ID for identifying the record.
The condition ID
92 defines a condition for carrying out a recovery process
using this record.
For example, "EMSG=0001" and "RMSG=0001" defined in a record
90a mean
that this record
90a is selected when the error message can be selected
on the selection condition
62 in a record of the error message selection
condition records
60 whose ID
61 is 0001 (according to EMSG=0001),
and the related message is in agreement with the condition
72 in a record
of the message selection condition records
70 whose ID
71 is 0001
(according to RMSG=0001).
Besides, for example, "ID=0001" and "Reply ID=0002" are defined in a record
90c. This means that the record
90c is selected when
a reply message of a command "ID=0001" defined in a record (record
90a)
of the recovery operation information records
90 whose ID
91 is 0001
is in agreement with the condition
72 of a record (record
70b)
of the message selection condition records
70 whose ID
71 is 0002.
That is, this means that a plurality of commands are transmitted when there occurs
an error designated by the condition ID
92 of the record
90a.
The CMD-ID
93 sets a command to be executed when there occurs an error
designated by the condition ID
92.
The contents to be set in the CMD-ID
93 is the ID
81 of the command
format record
80.
For example, if "0001" is defined in the CMD-ID
93 in the record
90a,
it means that a command in the command format record
80a is executed.
In the setting information
94, a character string to be substituted for
WORDn included in the command format
82 of the command format record
80
designated by the CMD-ID
93 is defined in the form of "WORDn=character string".
Information for selecting an information processing unit as a transmission
place of the command is defined in the transmission place
95.
The keywords shown in FIG. 8 can be designated in the setting information
94
and the transmission place
95.
EWORDn, RmWORDn and ClSmWORDn are just as described in the records of message
selection condition.
ESYS designates an information processing unit which outputted the error message.
RnSYS designates an information processing unit which outputted the related
message in agreement with the condition of SELn in the message selection condition
record
70.
CnSYS designates an information processing unit which transmitted an n-th command
for the error.
For example, if the setting information
94 is "WORD
1=EWORD
1"
in the record
90a, it means that the value of the first WORD of the
error message is substituted for the portion of WORD
1 of the command format
82. In addition, if the transmission place
95 is ESYS, it means that
the generated command is transmitted to an information processing unit which outputted
the error message.
Similarly, for example, a record
90e means that the value
of the fourth WORD of a message which is a reply message to the l-th command and
which is in agreement with the condition of SEL
3, is substituted for the
portion of WORD
1 of the command format
82, while an information processing
unit which outputted a related message in agreement with the condition of SELL
1
is set as the transmission place of the command.
The display name
96 designates a name to be displayed on the display unit
22.
The records
60 of error message selection condition, the records
70
of message selection condition, the records
80 of command format, and the
records
90 of recovery operation information are registered in the recovery
operation information file in advance.
In addition, the respective records may be automatically generated and registered
from commands inputted from the keyboard
23 by the operator.
The process for automatically generating and registering the respective records
will be described in detail with reference to FIGS. 10 to 14.
Next, the process for searching a related message will be described with reference
to FIG. 9.
FIG. 9 shows a process flow chart in which the process
14 for searching
a related message searches a message related to an error message received from
the communication process
11,
12 or
13.
In the process
14 for searching a related message, an error message acquired
from the communication process
11,
12 or
13 is divided per
WORD (Step
101).
Next, of the records
50 of information for searching a related message,
a record in which the value of WORD of the error message is in agreement with the
value of WORD designated by the selection condition
51 is searched from
the file
20 of information for searching messages (Step
102).
When a plurality of records of information for searching related messages are
detected at this time, a record having a largest number of conditions in the selection
condition
51 is selected.
Next, a message in agreement with the related message searching condition
52
of the acquired record
50 of information for searching a related message
is searched from the file
19 of message log information (Step
103).
The related message searched in the above-mentioned process for searching a related
message is displayed on the display unit
22 in the input-and-output process
17.
Referring to the error message and the related message displayed, the operator
inputs a command, or an instruction to display the contents of recovery operation,
from the keyboard
23 or the mouse
24.
The input-and-output process
17 acquires the inputted contents.
If a command is inputted, the command is transmitted to a designated information
processing unit through a corresponding communication process, while the process
15 for generating recovery operation information is executed to generate
recovery operation information.
If an instruction to display the contents of recovery operation is inputted,
the
process
16 for searching recovery operation information is executed to search
a corresponding method of recovery operation.
Next, the process for generating recovery operation information will be described
with reference to FIGS. 10 to 14 showing process flow charts of the process
15
for generating recovery operation information.
The process
15 for generating recovery operation information starts at
the process flow of FIG. 10.
In the process
15 for generating recovery operation information, the records
60 of error message selection condition are searched for a record whose
selection condition
62 is in agreement with the selection condition
51
of the related message searching information record
50 used for searching
a related message to the error message (Step
201).
When such a record of error message selection condition is absent, an error
message selection condition record
60 in which the contents of the selection
condition
51 of the record
50 of information for searching a related
message is set as the selection condition
62 is generated and registered
(Step
203).
Next, only conditions used for selecting a related message really detected
are extracted from the information of the related message searching condition
52
of the related message searching condition record used for searching the related
message (Step
204).
The records
70 of message selection condition are searched for a record
whose condition
72 is in agreement with the extracted conditions (Step
205).
When such a record of message selection condition is absent, a message selection
condition record
70 in which the extracted conditions are set as the condition
72 is generated and registered (Step
207).
Next, the records
90 of recovery operation information are searched
for a record in which the ID
61 of the searched or generated record
60
of error message selection condition and the ID
71 of the searched or generated
record
70 of message selection condition are set as the condition ID
92
(Step
208).
When such a record
90 of recovery operation information is absent, a
recovery operation information record in which the ID
61 of the searched
or generated record
60 of error message selection condition and the ID
71
of the searched or generated record
70 of message selection condition are
set as the condition ID is generated (Step
210).
Next, the contents of recovery operation (CMD-ID
91, setting information
92, and so on) corresponding to the searched or generated record
90
of recovery operation information are generated (Step
211). Then, the process
15 for generating recovery operation information is terminated.
FIG. 11 is a flow chart of the process for generating the contents of recovery
operation (Step
211 in FIG. 10).
One of commands inputted for an error message is acquired in the order in which
the commands were inputted (Step
301). Information to be set in the command
format
82 of the record
80 of command format and information to be
set in the setting information
94 of the record
90 of recovery operation
information are generated for the acquired command (Step
302). The detail
of Step
302 will be described with reference to FIG. 12.
Next, the command format records
80 are searched for a record whose
command format
82 is in agreement with the command format generated in Step
302 (Step
303). When such a command format record
80 is absent,
a command format record
80 is generated and registered while the command
format generated in Step
302 is set as the command format
82 (Step
305).
Next, information for selecting a transmission place (information processing
unit) of the acquired command is generated (Step
306). The detail of Step
306 will be described with reference to FIG. 13.
Next, it is confirmed whether a record
90 of recovery operation information
whose CMD-ID
93 is in agreement with the ID of the command format record
80, whose setting information
94 is in agreement with the setting
information generated in Step
302, and whose transmission place
95
is in agreement with the information for selecting a transmission place generated
in Step
306, has been defined or not (Step
307). When such information
has not been defined yet, such information is defined in a record
90 of
recovery operation information (Step
308), and the record
90 of recovery
operation information is registered (Step
309).
Next, it is judged whether the process from Step
302 to Step
309
has been carried out or not on all the commands inputted for the error message
(Step
310). When the process has been carried out on all the commands, the
process is terminated.
If the process has not been carried out on all the commands, a record
70
of message selection condition corresponding to a reply message is generated or
acquired (Step
311). The detail of Step
311 will be described with
reference to FIG. 14.
Next, the records
90 of recovery operation information are searched
for a record in which the ID
91 of the recovery operation information record
90 in editing and the ID
71 of the message selection condition record
70 generated in Step
310 are set as the condition ID (Step
312).
If such a record is absent, a record
90 of recovery operation information
in which the ID
91 of the recovery operation information record
90
in editing and the ID
71 of the message selection condition record
70
generated in Step
310 are set as the condition ID is generated (Step
314).
Next, the recovery operation information record
90 acquired in Step
312 or generated in Step
314 is set as a recovery operation information
record to be edited. Then, the process returns to Step
301 so as to acquire
the next command, and Step
302 et seq. are carried out on the command.
FIG. 12 is a process flow chart of Step
302 in FIG. 11.
In this process, information to be set in the command format
82 of the
command format record
80 and information to be set in the setting information
94 of the record
90 of recovery operation information are generated
from a command.
Specifically, the values of respective WORDs constituting an error
message, a related message and a reply message are searched from a command, and
respective information is generated on the basis of the value of WORD included
in the command.
First, messages to be searched for the value of WORD included in the command
are selected (Step
401).
The messages are selected sequentially in the order of an error message, a related
message and a reply message. The value of WORD constituting the selected message
to be searched is searched from the command (Step
402).
If the value of WORD of the message to be searched is included in the command,
the portion of the command is replaced by WORDn (Step
404), and setting
information of "WORDn=keyword" is generated in accordance with the contents of
FIG. 8 (Step
405).
Next, it is confirmed whether the process from Step
402 to Step
405
has been carried out or not on all the messages (Step
406). When the process
has been carried out, the process is terminated. When the process has not been
carried out, the process returns to Step
401.
FIG. 13 is a process flow chart of Step
306 in FIG. 11. In this process,
information for selecting the transmission place of a command is generated.
First, a transmission place of an inputted command is acquired to generate
information for selecting a transmission place (Step
501).
If the transmission place of the inputted command is the place which outputted
the error message, "ESYS" designating the place which outputted the error message
is set in the transmission place selection information (Step
503). Then,
the process is terminated.
If the transmission place of the inputted command is the place which outputted
a related message, "RnSYS" designating the place which outputted the related message
is set in the transmission place selection information (Step
505). Then,
the process is terminated.
If the transmission place of the inputted command is the transmission place of
a command inputted previously to the inputted command, "CnSYS" designating the
place which outputted the previously inputted command is set in the transmission
place selection information of the inputted command (Step
507). Then, the
process is terminated.
If the transmission place of the inputted command is the transmission place designated
by the value of WORD constituting each message, either "EWORDn", "RmWORDn" or "ClSmWORDn"
is set in the transmission place selection information in accordance with the kind
of the message on the basis of the keywords of FIG. 8 (Step
509). Then,
the process is terminated.
If the transmission place selection information is not any one of "ESYS", "CnSYS",
"RnSYS", "EWORDn", "RmWORDn" and "ClSmWORDn", the transmission place of the inputted
command is set as the transmission place selection information (Step
510).
Then, the process is terminated.
FIG. 14 shows a process flow chart of Step
311 in FIG. 11.
In this process, from the records
70 of message selection condition, a
record corresponding to a reply message is searched or generated.
First, from values included in the reply message, the value of WORD in the
error message, the value of WORD in the related message, and the value of WORD
in a reply message to a command inputted previously are searched (Step
601,
Step
602 and Step
603).
Next, the records
70 of message selection condition are searched for
a record in which the value of WORD of the reply message other than keywords designating
WORD detected in Step
601, Step
602 and Step
603 and the detected
values of WORDs is defined in the condition
72 (Step
604).
If such a record of message selection condition is absent, a message selection
condition record
70 in which the condition used in Step
604 is defined
in the condition
72 is generated and registered (Step
605).
In the process from FIGS. 10 to FIG. 14 described above, recovery operation information
in which the error message, the related message, the inputted commands and the
reply messages to
