    ****************************************************************
    * 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  *

    ****************************************************************
    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.
