Problem summary
**************************************************************** * USERS AFFECTED: DB2 10 and 11 for z/OS users who issue * * cancel during PREPARE of dynamic SQL * **************************************************************** * PROBLEM DESCRIPTION: A user cancel during full cache prepare * * can result in abends with various * * locations and reason codes, including * * but not limited to: * * RC00C90101 in DSNGEPDL * * RC00E70005 in DSNXEIST P012 * * RC00E70005 in DSN P000 * **************************************************************** * RECOMMENDATION: * **************************************************************** A small timing window exists after storing the SQL statement in the cache and disabling the recovery routine. If a cancel occurs within this window, the dependency records are freed with the assumption the SQL failed to get cached. Since the SQL did get cached, the SQL can execute without the protection of the dependency records and will point to freed storage.
Problem conclusion
If a cancel occurs in this window, the SQL statement will be marked invalid so that any attempt to execute it will cause it to be re-prepared. Additional Keywords: ABEND04E SQLDYNSTMTCACHE
