Status Messages

Apart from active monitoring by issuing the INGRMCDB monitor command after each monitoring interval, the CICS® - external subsystem monitoring function of SA z/OS also performs passive monitoring by updating the health status whenever it receives one of the following status messages:

  • DB2® messages:
    DFHDB2023I date time applid The CICS-DB2 attachment has connected to 
DB2 subsystem db2-id{|group}db2-group

DFHDB2025I date time applid The CICS-DB2 attachment has disconnected 
from DB2 subsystem db2-id{|group}db2-group

DFHDB2037 date time applid DB2 {subsystem |group} db2-id {is not active.
|has no active members.} The CICS-DB2 attachment facility is waiting.
  • IBM® MQ messages: 
    DFHMQ0307I date time applid Successful connection to queue manager
qmgr-name release vvrr {|group} qsg-name

DFHMQ0331I date time applid Adapter shutdown completed.

DFHMQ0334I date time applid Adapter shutdown successful.
These messages indicate whether the attempt to connect the CICS region applid to the DB2® external subsystem db2-id or whether the attempt to connect the CICS region to the MQ external subsystem was successful. In response to these messages, the health status is set to NORMAL if it was successful or MINOR if it was not.
