Error description

  • A LOAD of bitemporal tables might fail to detect duplicate /
    overlapping rows with INDEXING MODE REBUILD.
    
    A table may already contain existing rows. In some special
    scenarios it can occur that during subsequent LOAD there are
    more than just one rows loaded that are violating the
    overlapping business time constraint. These rows are not
    detected by LOAD and end up with an corrupted index.
    
    Running a db2dart against the table might show errors like this:
    
         Index inspection phase start. Index obj: 133  In pool: 234
           Scanning pages for unique index itoken(0) root page:1p.
           Scanning pages for unique index itoken(1) root page:2p.
             Error: Overlap with previous key in unique BTWO index.

    prev:13p,888,x0000000045370027.
             Error: Overlap with previous key in unique BTWO index.

    ...
    

Local fix

  • Specify explicitly INDEXING MODE INCREMENTAL in the LOAD command
