RM Monitoring Exclusions

Attention: This feature is in Early Adopter Product (EAP) release status. We intend to provide the finalized feature in a future release. Please contact Micro Focus SupportLine if you require further clarification.

You can exclude one or more RMs from CRCN processing by setting the following environment variable:

ES_XA_EXCLUDE_MONITORING=<RM-name>
<RM-name> is a resource managers that you want to exclude. Use the ID defined in the XAR definition to prevent monitoring. Exclude multiple RMs (maximum 50) by specifying multiple names ,separated by a ";".
Note: The RM name length must not exceed 8 characters in length.

Examples:

ES_XA_EXCLUDE_MONITORING=RM1;RM2;RM3
ES_XA_EXCLUDE_MONITORING=MYRM01;MYRM003

CRCN will exclude an RM if either:

  • The xa-ping pointer is set to low-values - this means no ping entry point was implemented in this xa resource switch module; or
  • The RM is specified by ES_XA_EXCLUDE_MONITORING.
Note: If an RM open string contains BATCHONLY, only a batch SEP will be able to access the resource manager. As CRCN is a CICS transaction, it will not monitor this entry. If the BATCH SEP encounters a severe XA error, the batch SEP will be recycled until the connection is recovered.
