Login Database

How to login database:

To analyze the SQL, you need to provide 2 accounts to login the database. The first one is the user can execute the target SQL, while the second one is the one has the privileges to monitor and anzlyze the target SQL, whom we call Monitoring User. The monitoring user should have the privilege to query the fixed views, such as v$session, v$sql and so on. You may use a DBA user as the monitoring user.
