Problem summary
**************************************************************** * USERS AFFECTED: All DB2 UDB for z/OS V8 and V9 users. * **************************************************************** * PROBLEM DESCRIPTION: ECSA storage shortage due to orphaned * * TRWA blocks. * * * * Message MSGDXR175E (IRLM IS UNABLE TO * * OBTAIN STORAGE - ECSA) received in * * syslog followed by DB2 abnormal * * termination with ABEND878 RC4. * **************************************************************** * RECOMMENDATION: * **************************************************************** A TRWA is unconditionally acquired during thread allocation if one does not exist for the thread. However, the agent driving the thread allocation could have a TRWA associated with it, and the TRWA created during thread allocation will overwrite the agent's existing TRWA pointer. This resulted in a leak of TRWAs, storage shortage in ECSA and DB2 abnormal termination. Please note that all TRWA storage is freed when DB2 termination occurs.
Problem conclusion
DB2 has been modified to use the agent's TRWA if one exists.
Temporary fix
