Hi Tom,


One user executed a SQL delete query "delete from table_name" consuming all the server resources and making the DB slow.

My requirement is to pause that long running sql query at the moment where it is instead of killing the user's session. So, how I can achieve this ?

Your help will be highly appreciated.

Thanks in advance.

No.

Once a statement has started there's no pause command. So you have to either wait until it's finished or kill the session (from 18c you can also cancel the statement, which stops it running and keeps the session alive).

You can use the Oracle Database Resource Manager to prioritise sessions, limit how many resources they consume, etc.:

Also, have a look at this slide deck for other options
