Error description
ABEND04E RC00E2000F LOC=DSNIDALC DSNSVSFB +08C6 The error occurs because a storage block allocated by DSNKCEST overlayed the storage manager trailer id of 'TRLA' with zeroes. When DSNIDALC requested the block to be freed, the sanity check of the trailer id was invalid so the abend was issued. Additional symptoms: DB2OVRLAY/K

Problem summary
**************************************************************** * USERS AFFECTED: * * All DB2 for z/OS V11 and DB2 for z/OS V12 * * users with indexes created as * * UNIQUE WHERE NOT NULL with INCLUDE columns. * **************************************************************** * PROBLEM DESCRIPTION: * * ABEND04E RC00E2000F * * LOC=DSNIDALC.DSNSVSFB+08C6 occurred * * while trying to free internal working * * storage. Access to a UNIQUE WHERE NOT * * NULL with INCLUDE column index was * * done during a fetch which resulted * * in a storage overlay. The storage * * overlay ultimately led to the abend. * **************************************************************** * RECOMMENDATION: * * Please apply the PTF when available. * **************************************************************** The storage overlay was the result of an invalid working storage area calculation. The calculation was done while trying to estimate the number of qualifying rows that were possible for a query. The calculation was using an index key length value that was not appropriate for a UNIQUE WHERE NOT NULL with INCLUDE columns index.
Problem conclusion
DB2 code has been modified to correctly calculate the amount of working storage needed while trying to estimate the number of qualifying rows for a given query. The correct calculation now accounts for indexes created as UNIQUE WHERE NOT NULL with include columns.
