Locked Tables

We can use view to check locks on Tables.

RAC / Cloud RDS: Tables locked more than 5 minutes

SELECT s.inst_id,d.OBJECT_ID, object_name, l.SESSION_ID,s.last_call_et, l.ORACLE_USERNAME, l.LOCKED_MODE from   gv$locked_object l, dba_objects d, gv$session s where  d.OBJECT_ID=l.OBJECT_ID and s.sid=l.SESSION_ID and s.last_call_et > 300 ;


NON-RAC / Cloud RDS: Tables locked more than 5 minutes

SELECT d.OBJECT_ID, object_name, l.SESSION_ID,s.last_call_et, l.ORACLE_USERNAME, l.LOCKED_MODE from   v$locked_object l, dba_objects d, v$session s where  d.OBJECT_ID=l.OBJECT_ID and s.sid=l.SESSION_ID and s.last_call_et > 300 ;

Execution_Explain Plan

Whenever we get request for application slowness or sql query then we need to identify sql_id and to analyze sql_id, we need to check SQL execution/explain plan. 1.
