Problem summary
**************************************************************** * USERS AFFECTED: DB2 9 for z/OS and DB2 10 for z/OS * * users of pair-wise join query with * * the dynamic statement cache enabled * * (CACHEDYN = YES) * **************************************************************** * PROBLEM DESCRIPTION: An ABEND04E RC00E70005 at DSNXRPJP * * M558 may occur when a pair-wise join * * query is executed multiple times and * * the SQL statement is cached and the * * previous execution of the SQL statement * * returned a negative sqlcode. * **************************************************************** * RECOMMENDATION: * **************************************************************** An ABEND04E RC00E70005 at DSNXRPJP M558 may occur when a pair- wise join query is executed multiple times in a system with the dynamic statement cache enabled (CACHEDYN = YES) and the previous execution returned a negative SQLCODE. After a negative SQLCODE is issued, a certain variable was not reset in this access path, allowing for subsequent executions of the statement to receive this error. The problem can apply to all pair-wise join queries, if and only if the pair-wise join query 1. is executed multiple times and 2. the system SQL dynamic statement cache is enabled (CACHEDYN = YES) and 3. a negative sqlcode is returned in previous execution of the same statement.
Problem conclusion
DB2 is modified to re-initialize the variable properly before pair-wise join is executed. Additional Keywords: SQLPAIRWISEJOIN SQLDYNSTMTCACHE ABEND04E RC00E70005 DB2PARALL/K
