Problem summary
**************************************************************** * USERS AFFECTED: All DB2 11 and DB2 10 for z/OS users of Real * * Time Statistics. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect number of times that index or * * partition is accessed will be returned * * by Real Time Statistics sub-component * * (via field REORGINDEXACCESS of catalog * * table SYSINDEXSPACESTATS ). * **************************************************************** * RECOMMENDATION: * **************************************************************** DB2 Real Time Statistice will count the number of times that the index was used for SELECT, FETCH, searched UPDATE, searched DELETE, or used to enforce referential integrity constraints. Prior to this fix, DB2 count redundant number of times when DB2 is deleting an index entry. So the field REORGINDEXACCESS of catalog table SYSINDEXSPACESTATS is mismatching the factual situations that an index was used.
Problem conclusion
DB2 code has been modified to make sure that deleting index entry will not be counted by the the online statistice process.
