Error description
CICS region receives the following message: DFHLG0772 An error has occurred during MVS logger operation IXGQUERY CHECKCONNSTATUS(YES) for log stream xxxx.yyyyyyy.DFHLOG. MVS logger codes: X'00000008', X'0000082D'. Log stream attributes: SYSTEMLOG(YES), DASDONLY(YES), STRUCTNAME(****************), RETPD(X'00000000'), AUTODELETE(NO). The IXGQUERY reason code means IXGRSNCODEEXPIREDSTMTOKEN error. The stream token is no longer valid because the connector has been disconnected. This is followed by the following messages: DFHLG0735 A failure has occurred while writing to the system log (DFHLOG). Access to the system log has been lost. CICS will be terminated. DFHKE1800 ABNORMAL TERMINATION OF CICS IS COMPLETE. CICS design in such a case is to terminate and emergency restart with Reconnect. This does this to avoid any potential issue with the data integrity and consistency. This APAR is being taken to put out a more informative message as to this behavior for these logger codes.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: No informational message issued for an * * IXGLOGR error with reason code of * * IxgRsnCodeExpiredStmToken (0000082D). * **************************************************************** If CICS is returned an 8,82D response from the z/OS Logger then it issues generic failure message DFHLG0772. There is no explanation of why CICS has to terminate in this particular case.
Problem conclusion
The CICS log manager will issue new informational message DFHLG0803 if a call to the z/OS logger returns an error with a reason code of an IxgRsnCodeExpiredStmToken (0000082D). The CICS Messages manual will be updated with the following new message: DFHLG0803 applid The z/OS logger has detected an expired stream token on an operation against a CICS system log logstream. Explanation: The z/OS logger has returned an IxgRsnCodeExpiredStmToken (0000082D) Reason Code to the CICS log manager. The token invalidation may be the result of an IXGLOGR region failure, for example. System action: CICS has to terminate and reconnect to the logstream during the next startup. An emergency restart will ensure any inflight work is backed out in a coordinated manner. User response: This is an informational message. Refer to earlier message DFHLG0772 for further details of the z/OS logger operation and logstream which returned the IxgRsnCodeExpiredStmToken Reason Code.
