DFHZC2300 APPLID Recovery action requested for connection sysid.

Explanation

The XZIQUE global user exit program has been invoked by CICS because of a potential problem with the connection. The global user exit has used return code UERCAKLL indicating that throughput on the connection is abnormally low and some exceptional action is required. The poor performance of the connection can be caused by:

  • Poor response on the receiving end

  • Increased load on the sending end.

The condition may be intermittent. Message DFHZC2301 may follow indicating that the connection has recovered.

This message may also occur when the XZIQUE global user exit is disabled but the connection has been at the QUEUELIMIT for MAXQTIME where both parameters are specified in the connection definition.

System action

CICS cancels all transactions which have outstanding queued requests to use the connection.

User response

Investigate the cause of the poor performance of the connection. Check the availability and condition of the connected system.
