Display the Session / Serial / Instance information used by the current worksheet - so that its easier to identify these sessions (and assist in killing them in the DB. )
Use Case : Once a query takes a lot of time to execute, hitting cancel query request just makes the worksheet stuck. Developers need to reach out to DBA to kill sessions with runaway queries, and DBA asks for the session/serial/instance information to use in the kill command. This is more urgent in production systems where long running queries are monitored for and escalated against the developer.
