Problem summary
**************************************************************** * USERS AFFECTED: All DB2 10 for z/OS users. * **************************************************************** * PROBLEM DESCRIPTION: An ABEND04E RC00E2000C can occur at * * location DSNIWCUB.DSNSVSVB+0AC2 for * * processing that involves an intensive * * use of sort workfiles for a very large * * sort. * **************************************************************** * RECOMMENDATION: * **************************************************************** An ABEND04E RC00E2000C can occur at location DSNSVSVB +0AC2 for processing that involves an intensive use of sort workfiles for a very large sort. In the reported error case, the number of sort workfiles exceeded 300k. During the input phase of sort, there can be a large amount of data to sort. This can trigger the generation of multiple workfiles. As more and more workfiles are created (which accumulate), more storage is needed (and used) to keep track of this information. If this amount gets very large, it can exhaust the storage allotted for this administration.
Problem conclusion
The code in DB2 has been modified to perform intermediate merges of the input data as the number of workfiles increases. This should prevent the storage abend and other possible 'resource unavailable' conditions from occurring. Additional Keywords: SQLSORT DB2STGLK/K OFFSET0AC2
