ORA-00031: session marked for kill

I got ” ORA-00031: session marked for kill ”  error in Oracle database.

 

ORA-00031: session marked for kill

 

Details of error are as follows.

ORA-00031: session marked for kill.

Cause: The session specified in an ALTER SYSTEM KILL SESSION command cannot be killed 
immediately (because it is rolling back or blocked on a network operation), but it has been 
marked for kill. This means it will be killed as soon as possible after its current 
uninterruptible operation is done.

Action: No action is required for the session to be killed, but further executions of the 
ALTER SYSTEM KILL SESSION command on this session may cause the session to be killed sooner.
