00E50007
Explanation
An execution unit which, according to tracking information, is currently suspended on a latch waiter chain issued a request to test or to release a latch. A single execution unit cannot be doing both at the same time. This is probably a DB2® subsystem error.
System action
The requesting execution unit is abended.
Operator response
Notify the system programmer.
System programmer response
Collect the necessary diagnostic materials. 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
At the time of the abend, general register zero contains the address of the latch upon which the execution unit is supposedly waiting and general register two contains the address of the resource options block (ROB) which was put on the latch waiter chain.
A record is written to SYS1.LOGREC and a DB2 SVC dump is requested.
- 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).
- Listing of SYS1.LOGREC data set, obtained by executing IFCEREP1.
