Eliminate dupliates from SYSREC input file before running LOAD.
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 9 for z/OS and DB2 10 for z/OS users * * running LOAD on a table with a unique index. * **************************************************************** * PROBLEM DESCRIPTION: LOAD utility issuing a huge number * * of MSGDSNU345I messages, along with a * * MSGICE247I message, resulted in * * ABEND04E RC00E40020, and ABEND04E * * RC00E20015 at DSNSVSTK + x'0124'. * * DB2 subsystem abnormally terminated * * with ABEND04F RC00E50706. * **************************************************************** * RECOMMENDATION: Apply corrective PTF when available. * **************************************************************** A LOAD utility was run on a table with a unique index. During the LOAD, a huge number of duplicate keys were detected resulting in DSNU345I - UNIQUE INDEX KEY DUPLICATES KEY FROM INPUT RECORD... being issued. During the LOAD, message ICE247I - INTERMEDIATE MERGE ENTERED - PERFORMANCE MAY BE DEGRADED was also issued. Following this, LOAD abended with ABEND04E RC00E20015 at DSNSVSTK + x'0124' followed by ABEND04E RC00E40020. DB2 then issued MSGDSNV086E - DB2 ABNORMAL TERMINATION and abnormally terminated with ABEND04F RC00E50706 due to below the bar storage shortage. The storage shortage occurred because the control blocks used to handle duplicate keys were not reused nor deallocated, but always newly allocated when processing the duplicate keys.
Problem conclusion
The code has been modified to properly allocate and reuse storage for duplicate keys processing.
Temporary fix
