How can you view the Oracle service name?

To view the Oracle service name, you can use the following methods:

1. Connect to the Oracle database using the SQL*Plus command line interface, and then execute the following query statement:
2. Retrieve the name from the v$database table.
3. This will return the service name of the current database.
4. Log in to Oracle database using Oracle Enterprise Manager (OEM) or another database management tool, then navigate to the “Database Instance” or similar section to locate the service name information.
5. Check the tnsnames.ora file on the Oracle database server. This file is typically located in the $ORACLE_HOME/network/admin directory, where $ORACLE_HOME is the root directory where Oracle software is installed. In this file, you can find the service name definitions for the database.

Any of these methods can help you view the service name of an Oracle database.
