00E50054
Explanation
The DB2® subsystem is abended by the synchronization services recovery routine when an unrecoverable error is encountered during recovery processing for the suspend, cancel, resume, or SRB redispatch functions. This is a subsystem termination reason code.
System action
The DB2 subsystem is terminated. This reason code is associated with an '04F' abend code indicating that synchronization services was responsible for termination.
Operator response
Notify the system programmer, and restart DB2.
System programmer response
If you suspect an error in DB2, you might need to report the problem. For information about identifying and reporting the problem, see Collecting diagnostic data.
Problem determination
Scan the MVS™ system log and the contents of SYS1.LOGREC for DB2 abends occurring immediately before the system termination message DSNV086E. Follow the failure analysis procedures for the specific abends. Refer to the appropriate CICS® documentation for information about about X'04F' and X'04E' abend completion codes.
- Unable to complete resume processing for an SRB mode execution unit that was suspended at time of error.
- Errors were encountered during primary recovery processing causing entry to the secondary recovery routine.
- Recovery initiated retry to mainline Suspend/Resume code caused retry recursion entry into the functional recovery routine.
- Unable to obtain or release the cross-memory lock (CML) of the system services address space either during mainline processing or during functional recovery processing (for example, reason code '00E50051' or '00E50052').
- The invoking resource manager requested the TCTL=YES option of the resume function while executing in TCB mode (for example, reason code '00E50051').
- Console output from the system on which the job was run, and a listing of the SYSLOG data set for the period of time that spans the failure.
- Listing of SYS1.LOGREC data set, obtained by executing IFCEREP1.
