00E50712
Explanation
An error occurred in a latch manager function attempting to terminate the holder of a Db2 latch. The holder's TCB has been set nondispatchable by MVS and a CALLRTM to terminate this TCB has failed.
System action
The Db2 subsystem is terminated.with this reason code.
Operator response
Notify the system programmer of the failure and restart Db2.
System programmer response
Scan the SYS1.LOGREC entries for one or more Db2 abends immediately prior to the subsystem termination. 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
A Db2 dump of the error is requested and a record entered into SYS1.LOGREC. Register 3 at time of error contains the latch-holder's TCB address in the home address space and register 4 contains the return code from CALLRTM. Refer to Db2 abend completion codes (X'04E' and X'04F) for information about X'04E' and X'04F' abend completion codes.
- 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.
- Dynamic dump, taken to SYS1.DUMPxx data set, by Db2 (04E and 04F abends).
- A listing of the SYS1.LOGREC data set, obtained by executing IFCEREP1.
