To view the status of Oracle database connections, you can use the following methods:

  1. Query using SQL:
SELECT sid, serial#, username, machine, program
FROM v$session;

This SQL statement will display all current database sessions, including the session ID (sid), serial number (serial#), username, connected machine name (machine), and program name (program).

  1. By using Enterprise Manager (EM):
    By logging into Oracle Enterprise Manager, you can check the current database instance’s connection status. On the EM homepage, click on the “Performance” tab and select the “Top Activity” option to view the current number of connections and active sessions.
  2. Utilizing SQL Developer:
    In the Oracle SQL Developer tool, after opening the database connection, click on the “DBA” option under the “View” menu, then expand the “Sessions” node to view the current database session status.

By using the above method, it is easy to check the connection status of Oracle databases.
