14.3.14 Changing the send retry interval and the number of retries for sending unreported information

If inter-process communication between the event/action control manager and the event/action control agent fails for a reason such as a busy network or a defective line, the information that could not be sent is managed as unreported information.

The following describes the default values for the send retry interval and the maximum number of retries.

For a resend from the manager host to the agent host:
  • When connection to the agent host times out
    The send retry interval is 300 seconds for the first retry, 600 seconds for the second retry, 900 seconds for the third retry, 1,800 seconds for the fourth retry, and 3,600 seconds for the fifth and subsequent retries. The maximum number of retries is 27 (24 hours).
  • In all other cases
    The send retry interval is 30 seconds, and the maximum number of send retries is 2,880 (24 hours).

For the resending of information from the agent host to the manager host (resending information when an event job monitoring condition is satisfied):
  • The send retry interval is 10 seconds, and the maximum number of send retries is 8,640 (24 hours).

In cases other than when a connection to the agent host is impossible (that is, a timeout occurs), you can change the send retry interval and the maximum number of send retries for unreported information. Note, however, that changing these settings affects the processing of a resend from the manager host to the agent host as described below.

Before the settings are changed:
Regardless of whether the cause of a network error that occurred is a timeout for connection to the agent host or not, all send retries end in 24 hours.

After the settings are changed:
If a timeout for connection to the agent host occurs 27 times in succession, or if the number of send retries reaches the maximum (default: 2,880), there will be no more retries.

As described above, after settings are changed, the completion of a resend operation could require a long time if a connection to the agent host times out and another network error occurs concurrently. This problem can be prevented by specifying settings that ensure that the sending of unreported information is retried at regular intervals.

For details, see 14.3.13 Settings for ensuring that the sending of unreported information is retried at regular intervals.

Use the procedure below for changing the settings.

Organization of this subsection
(1) Definition procedure
(2) Environment setting parameter

(1) Definition procedure

(a) For a standard configuration

  1. Stop the JP1/AJS3 service.
    Execute the following commands to confirm that all processes have stopped:
     
# /etc/opt/jp1ajs2/jajs_stop#1
# /opt/jp1ajs2/bin/jajs_spmd_status

    #1:
    Confirm that automatic termination has been set.

  2. Execute the following command to set the environment setting parameter described in (2) below:
     
jajs_config -k definition-key "parameter-name"=value

  3. Restart JP1/AJS3.
    The new settings are applied.

(b) For a compatible ISAM configuration

  1. Stop the JP1/AJS3 service.
    Execute the following commands to confirm that all processes have stopped:
     
# /etc/opt/jp1ajs2/jajs_stop#1
# /opt/jp1ajs2/bin/jajs_spmd_status

    #1:
    Confirm that automatic termination has been set.

  2. In an editor such as vi, create a configuration file that defines the environment setting parameter described in (2) below.

  3. Save the file and then execute the following command:
     
jbssetcnf configuration-file-name
    The path of the jbssetcnf command is /opt/jp1base/bin/jbssetcnf. For details on this command, see the Job Management Partner 1/Base User's Guide.

  4. Restart JP1/AJS3.
    The contents of the configuration file are applied to the system.

(2) Environment setting parameter

Table 14-41 Environment setting parameters for setting the send retry interval and number of retries for sending unreported information

Definition key Environment setting parameter Explanation

Communication from the manager host to the agent host:
  • For all scheduler services
    [{JP1_DEFAULT|logical-host}\JP1AJS2\SCHEDULER\EV\MANAGER]#
  • For a specific scheduler service
    [{JP1_DEFAULT|logical-host}\JP1AJSMANAGER\scheduler-service\EV\MANAGER]#
  • For a compatible ISAM configuration
    [{JP1_DEFAULT|logical-host}\JP1AOMMANAGER]#

Communication from the agent host to the manager host:
[{JP1_DEFAULT|logical-host}\JP1AOMAGENT]#
 "NotificationRetryInterval"= Interval for retrying the sending of unreported information
"NotificationRetryCount"= Maximum number of retries for sending unreported information

#:
The specification of the {JP1_DEFAULT|logical-host} part depends on whether the host is a physical host or a logical host. For a physical host, specify JP1_DEFAULT. For a logical host, specify the logical host name.

For details about defining the environment setting parameters for communication from the manager host to the agent host, see the following:
