Hello gurus, I got this error and I want to confirm my concepts are right. Session 1 delete from tab1 where col1=20; 0 rows deleted session2 truncate table tab1; I get "ORA-00054: resource busy and acquire with NOWAIT specified" When session1 deleted 0 records, it should not be placing any locks on the table correct? I do not understand why I got the error. Am I missing some basic concept? When I did a rollback on the session1 then session2 was able to truncate the table.
