Grant command hanging for long time
Posted by Pavan DBA on April 2, 2017
Recently I have faced one issue regarding granting some privileges to the user.
I got a request to grant select on a table to a user. when I issued grant command, it just got hung.
Even though select doesn’t hold exclusive lock on a table, I verified in v$locked_object to check if any more information can be collected.
select object_id,session_id,oracle_username from v$locked_object;
OBJECT_ID SESSION_ID ORACLE_USERNAME
———- ———- —————
26187 18 SCOTT
select object_name,owner,object_id,object_type,status from dba_objects where object_id=26187;
OBJECT_NAME OWNER OBJECT_ID OBJECT_TYPE STATUS
———– —– ——— ———– ——
OBJ$ SYS 26187 TABLE VALID
From the above, it is evident that SCOTT user is holding a lock on SYS.OBJ$ table which actually caused the issue.
After confirmation from application team, I have killed the session with id 18. After that grant command got successful.
Hope this helps…
