Monitoring Resource Managers

A CICS system transaction, CRCN, is available to monitor the state of XA connections for each resource manager (RM) entry defined in the system.

CRCN is a replacement for the former XA Reconnect facility that recycled SEPs on connection loss. The XA Reconnect facility was configured by setting the ES_XA_RECONNECT environment variable. CRCN also uses this environment variable, although its usage differs slightly.

Note: CRCN does not monitor RMs which have been defined with the BATCHONLY parameter.
