Mark CICS as unhealthy from the CPSM WLM point of view, if RM like e.g. DB2 is not available, but is essential for most trans

If the application ( e.g. described by a trangroup, by the whole WLM specification ) in a CICS region has a dependency on WMQ, IMS or DB2 and the connection to these resources managers is down, CICSPlex SM should mark these regions as unhealthy until the connections to the resource managers are re-established. Because this is not equal to all customers, this must be controlled by parameters.

    Please could you answer the following question for us:

    Are you aware of the existing CICS-DB2 functionality concerning Connecterror(sqlcode) on the DB2CONN definition ? In this situation, if the CICS-DB2 Attach is in standbymode because DB2 is not there, then a -923 SQLCODE is returned to the application and CICS-DB2 Attach issues a iwmmabnl call to mark the WLM performance block to indicate an error has occurred. This is to avoid the "storm drain" problem whereby CPSM might be tempted to think the request ran quickly and so send more work to that region. CPSM will detect the PB has been marked and will route work away from the region.
