6.3.15 Environment setting parameters related to communication for event/action control

When an event job or a jobnet with start conditions is executed, the event/action control manager and the event/action control agent communicate with each other. If a communication error occurs, communication is retried.

A retry interval and a maximum number of retries can be set by using the environment setting parameters for event/action control. Note that these parameters must be specified in a combination appropriate for the case.

This subsection provides examples of setting environment setting parameters that must be used in appropriate combinations.

For details about a specific environment setting parameter, see the description of that parameter.

Organization of this subsection
(1) Changing the retry interval for retries caused by a connection timeout
(2) Changing the retry interval for retries that are not caused by connection timeouts

(1) Changing the retry interval for retries caused by a connection timeout

When an event job or a jobnet with start conditions is executed and the event/action control manager attempts to connect to the event/action control agent to communicate, if the attempt times out, the manager performs a retry. With the default settings, for each retry, the manager gradually increases the interval, instead of using the regular interval, to gradually reduce the retry frequency. Gradually increasing the interval can reduce the impact on the processing speed of event jobs executed on other agents even when connection timeouts from the event/action control manager to the event/action control agent continue to occur.

For details about this retry process and interval, see Table 2-3 in 2.2.2(5) Notes on manager/agent system configurations in the Job Management Partner 1/Automatic Job Management System 3 System Design (Configuration) Guide.

However, if a connection timeout is due to a temporary cause, the retry process described above takes more time, delaying the execution of an event job or jobnet with start conditions on the execution agent. If the gradually increasing retry interval is not convenient, you can also use the regular interval for retries that are caused by connection timeouts for retries that are not caused by connection timeouts.

For details about the interval for retries that are not caused by connection timeouts, see (2) Changing the retry interval for retries that are not caused by connection timeouts.

If you want retries to be performed at regular intervals, set the NotificationConstantRetry environment setting parameter. Note, however, that if a connection timeout status continues for a long time, retries at regular intervals might make the frequency at which the system waits for a connection greater than that for retries at gradually increasing intervals, thereby delaying other processing. For these cases, in addition to the NotificationConstantRetry environment setting parameter, use the ClientConnectTimeout environment setting parameter to adjust the connection timeout value for communication related to event jobs and jobnets with start conditions.

#:
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.

(2) Changing the retry interval for retries that are not caused by connection timeouts

For communication between the event/action control manager and agent during execution of an event job or a jobnet with start conditions, the interval for retries not caused by connection timeouts is set by the NotificationRetryInterval environment setting parameter. Similarly, the maximum number of retries not caused by connection timeouts is set by the NotificationRetryCount environment setting parameter.

Note that if you change only the retry interval or only the number of retries, the retry period (the period during which retries can be performed) also changes. If you want to retain the retry period, you need to adjust the values of both environment parameters.

For example, if you change the retry interval to 15 seconds, which is half the default value, the number of retries to preserve the retry period is 5,760, which is twice the default value.

For a network error that is caused by a connection timeout, adjust the settings described in (1) Changing the retry interval for retries caused by a connection timeout.
