Air pocket. Does anyone have any insight to this issue. I feel I am overlooking a fundamental - or its to early in the morning. As the owner of the table, a colleague was unable to truncate a table. (He committed his session first), receiving a Resource Busy, ORA-00054. I was able to delete table and commit easily from another session (as non owner). There are no foreign keys, it is neither a parent nor child. No unique or primary constraints, and no indexes. (Some check constraints (not null only)). This lock query returned no rows. SELECT sid, DECODE( block, 0, 'NO', 'YES' ) BLOCKER, DECODE( request, 0, 'NO', 'YES' ) WAITER FROM v$lock WHERE request > 0 OR block > 0 ORDER BY block DESC; The delete worked before more investigation could be done. (Trying to force revealing a blocker) - production db. My search criteria for metalink and google is not returning what I need yet. (of course I rarely search metalink well). Searching with oracle-l or ask tom came close but no cigar. Best Regards, Joel Patterson Database Administrator 904 727-2546
