To control a query:

1 In the Query Monitor portlet, click on the session with the identified bad query. The Details view appears.

2 You can use the Tools menu to:

  • Change the query priority
  • Abort the query
  • Abort and log off the session
  • Note: Use the following guidelines when considering whether to abort a session:

  • Do not abort the session if it is still running other queries.
  • If the session is not running other queries:
  • If the query is a SELECT statement, you can safely abort the query.
  • If the query includes an INSERT, UPDATE, DELETE, or other statement that changes data, aborting a partially completed query may cause data problems.
