ABEND0C4 RC00000038 IN DSNXOCSC OFFSET271C CAN OCCUR FOR A QUERY ELIGIBLE FOR STAR JOIN AND THERE ARE SKIPPED KEYS IN THE FACT TABLE INDEX
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of star join on DB2 11 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: ABEND0C4 RC38 in DSNXOCSC OFFSET271C * * can occur on a query eligible for star * * join * **************************************************************** * RECOMMENDATION: * **************************************************************** ABEND0C4 RC38 in DSNXOCSC OFFSET271C can occur for a query eligible for star join. As DB2 costs the query for star join, it may encounter skipped keys, where some of the leading columns of the fact table index do not have matching predicates in the query. These skipped keys are not handled properly when determining whether matching predicates are order-preserving or not, which leads to the abend. Additional Keywords: SQLSTARJOIN ABEND0C4 RC38 DSNXOCSC OFFSET271C OFFSET01271C
Problem conclusion
Code is updated to allow for such skipped keys during star join costing.
