APAR status

  • Closed as program error.

Error description

  • rmstream is blocked if the stream has view attached.
    However, if there is a new view that the stream master site does
    not know about because the remote site has not sync'd to the
    stream master since creating the view, then the rmstream is
    allowed to proceed.
       (Of course this is unavoidable.)
    
    Remote sites may have database problems affecting reformatvob
    and mkreplica, after they import the "rmstream" oplog entry.
    
    Examples:
    db_dumper: Error: Unexpected error from database library (8) in
    "/vobs/atria/lib/db/db__dump.c" line 3280
    db_dumper: Error: Error from libdb (8)
    cleartool: Error: Could not dump database.
    
    db_dumper: Error: Database identifier nnnnnn requested by client
    "" not found in VOB "/cag/drobinson/rms_pvob.vbs/db.reformat" in
    file "/vobs/atria/lib/db/db__obj.c" line 970.
    db_dumper: Error: Unexpected error from database library (1) in
    "/vobs/atria/lib/db/db__dump.c" line 6241
    db_dumper: Error: Error from libdb (1)
    cleartool: Error: Could not dump database.
    

Local fix

  • Contact ClearCase Technical Support for assistance to clean bad
    records out of the VOB database.
