I am on Oracle 11g R1, 2 node RAC on AIX OS. My issue is that there is a session which is killed (not marked killed but is actually killed) but still this session has acquired a lock on a table. In gv$transaction, USED_UBLOCK corresponding to this session's address is equal to 1 for last 2-3 hours and is not changing at all. Such a situation occurs almost in every 2-3 days in our environment. The people in ETL team load data in some or the other table using mappings.
