Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 9 and DB2 10 users of SELECT FROM * * MERGE sql statements * **************************************************************** * PROBLEM DESCRIPTION: Storage leak of DBM1 control blocks * * with eyecatcher UZB in long-running * * threads that run SELECT FROM MERGE * * sql statements. * * ABEND04E may also occur at DSNSVBK * * with one of the following reason codes: * * RC00E20003 RC00E20004 RC00E2000B * * RC00E2000C . * **************************************************************** * RECOMMENDATION: * **************************************************************** Excessive storage growth occurs in the DBM1 address space when long-running threads ran sql SELECT FROM MERGE statements. This can eventually lead to a local storage shortage in which the maximum storage for an agent local pool is exceeded. The pool may be unavailable for further storage. These conditions are caused when a control block with eyecatcher UZB is not properly freed at statement clean up time.
Problem conclusion
DB2 code has changed to free the control block with eyecatcher UZB at statement clean up time for SELECT FROM MERGE statements. This releives the proliferation of such blocks and also the out of storage conditions. Additional Keywords: FINAL TABLE WHEN MATCHED UPDATE DB2STGLK/K
Temporary fix
