Error description

  • The error does not happen on HADR environments.
    
    After ROLLFORWARD, data stored in table and in index is out of
    sync. Data scan vs index scan will return different results
    (data is the correct one). Index may have some records missing,
    but all records in index are present in table.
    
    The scenario is rollforward through (both LOADs must be in
    rollforward window, and operate on same table).
    LOAD COPY YES ... INDEXING MODE REBUILD
    LOAD COPY YES ... INDEXING MODE INCREMENTAL
    
    ROLLFORWARD of LOAD COPY YES ... INDEXING MODE INCREMENTAL must
    mark indexes bad, as the COPY image does not contain any index
    data.
    Under certain scenarios (see below), index may not be marked
    bad.
    
    Rollforward window must include LOAD COPY YES ... INDEXING MODE
    REBUILD and LOAD COPY YES ... INDEXING MODE INCREMENTAL.
    At least one LOAD ... REBUILD must precede LOAD ... INCREMENTAL.
    Problem does not happen when LOAD ... REBUILD is the last LOAD.
    

Local fix

  • Force index rebuild. Either drop/recreate index, or mark index
    bad explicitly.
