Error description
Reduced index build parallelism on parallel partition LOAD when running with DB2 Sort
Local fix
N/A
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 9 for z/OS, DB2 10 for z/OS, and * * DB2 11 for z/OS LOAD utility users * **************************************************************** * PROBLEM DESCRIPTION: Reduced index build parallelism when * * running LOAD with partition parallelism * * and DB2 Sort for z/OS caused by message * * DSNU397I DSNURPIB - NUMBER OF TASKS * * CONSTRAINED BY VIRTUAL STORAGE BELOW. * **************************************************************** * RECOMMENDATION: Apply corrective PTF when available * **************************************************************** LOAD against a table space with multiple partitions and multiple indexes was using parallelism for both partitions and indexes as indicated by messages DSNU364I DSNURPPL - PARTITIONS WILL BE LOADED IN PARALLEL, NUMBER OF TASKS = mm and DSNU395I DSNURPIB INDEXES WILL BE BUILT IN PARALLEL, NUMBER OF TASKS = nn. When using DB2 Sort for z/OS the number of index build tasks was less than optimal and MSGDSNU397I indicated virtual storage constraints below the line. This happened for a large number of partitions being loaded in parallel and caused longer elapsed times. Additional keywords: MSGDSNU364I MSGDSNU395I
Problem conclusion
Code was changed to correct the calculation of parallel subtasks when running with DB2 Sort for z/OS.
Temporary fix
