Error description

  • When migrating to IBM ClearCase 9.1.0, reformatting schema 54
    PVOBs created on earlier releases will fail with the following
    message:
    0 derived objects dumped.
    db_dumper.exe: Error: Internal error in
    "\atria\lib\db\db__dump.c" line 476
    db_dumper.exe: Error: INTERNAL ERROR detected and logged with
    the NT Event Service.
    See the Event Viewer for the error message.
    db_dumper.exe: Error: ***ABORT*** '\atria\lib\db\db__err.c':358
    
    The issue appears to be caused by a difference in a UCM data
    structure interpretation between 9.0.x and 9.1.0. This issue is
    specific to UCM project VOBs that successfully reformat on
    earlier releases. UCM component VOBs and non-UCM VOBs are not
    impacted by this issue.
    

Local fix

  • If migrating from an earlier 8.0.x or 9.0.x release, reformat
    the PVOB to schema 80 before attempting to use the VOB on 9.1.0
    as this impacts **ONLY** schema 54 VOBs.
    
    If migrating from a a release that does not support VOB schema
    80 (7.x and before), treat the issue as a move between different
    processor architectures:
    - Dump the VOB using cleartool reformatvob -dump on the older
    system.
    - Migrate the VOB to the new server or upgrade the server host
    to 9.1.x
    - Load the VOB using cleartool reformatVOB -load.
