CA XCOM Data Transport Health Checks › XCOM_MAXREM_LEVEL@stcname

XCOM_MAXREM_LEVEL@stcname

Description

This check monitors the number of remotely-initiated tasks that are active within the CA XCOM Data Transport region. The purpose of this check is to provide an alert when the number of remotely-initiated active tasks reaches a threshold percentage of the maximum allowed by the MAXREM parameter. The default interval for this check is every 30 minutes.

Best Practice

The MAXREM value should be set to a level that does not allow more concurrent transfers to run than there are system resources to support and that does not exceed the MAXTASK parameter.

Parameters Accepted

This check accepts one parameter, THRESHOLD(nnn). The value specified in THRESHOLD(nnn) is used to determine how close to the MAXREM limit the total number of active tasks can be before an exception is recognized. This parameter must be an integer in the range of 1 to 100. The default is THRESHOLD(80).

Reference

For information about tuning the MAXREM parameter, see the chapter "Configuration Parameters."

Exception Message

XCMH533W The total number of remotely initiated active tasks within the CA XCOM Data Transport region has exceeded nnn% of the configured limit as specified on the MAXREM parameter.

The MAXREM configuration parameter limits the number of remotely-initiated active tasks that are allowed in the CA XCOM Data Transport region at any given time. An exception condition is recognized when the remotely-initiated active task level reaches a certain threshold percentage of that limit. The default threshold percentage is 80%. This threshold may be modified by specifying a different percentage via the THRESHOLD(nnn)" parameter for this particular health check.

When a CA XCOM Data Transport region reaches the MAXREM limit, additional remotely-initiated file transfer requests are delayed and retried at a later time. This may result in unacceptable processing delays for new file transfer requests. The overhead required to manage this exception condition may degrade the overall performance of the CA XCOM Data Transport region and adversely affect its ability to complete existing file transfer requests.
