To view the number of connections to the Oracle database, you can follow these steps:

  1. Log in to the command line window or remote terminal on the Oracle database server.
  2. Log in to the Oracle database instance using a user with sysdba privileges. For example, you can use the following command to log in as a user with sysdba privileges:
  3. Accessing SQLPlus as the system DBA.
  4. Run the following query to see the current number of connections:
  5. How many sessions are there in the v$session view?
  6. This will return the current number of active connections.
  7. If you want to view detailed connection information, you can run the following query.
  8. Retrieve the session ID, serial number, username, and machine information from the v$session table.
  9. This will return the session ID (SID), serial number (Serial#), username, and machine name of the active connection.

Please note that these queries require a user with sysdba privileges to log in to the Oracle database instance. If you do not have sysdba privileges, please contact the database administrator or a user with the appropriate permissions to execute the queries.
