Configuring network service names
![[IMPORTANT: ]](images/important.png) | IMPORTANT: If IMC servers use different Oracle databases in a distributed deployment, you must configure a unique network service name for each database. | |
To enable IMC to connect to remote databases, you must configure correct network service names on the Oracle database server and client.
You can configure network service names by using Oracle Net Manager or Oracle Net Configuration Assistant, or by modifying the tnsnames.ora file. This procedure uses Oracle Net Configuration Assistant.
To use Oracle Net Manager, see "Configuring the Oracle client"
To modify the tnsnames.ora file, see "Configuring the network service name of the database."
To configure the network service name by using Oracle Net Configuration Assistant:
Start the database service.
See "Starting the Oracle service manually" for the operation procedure.
Start Oracle Net Configuration Assistant.
cd $ORACLE_HOME/bin ./netca
The Welcome page opens.
Select Local Net Service Name configuration and click Next, as shown in Figure 51.

Select Add and click Next, as shown in Figure 52.

Enter the database service name orcl and click Next, as shown in Figure 53.
The service name must be the same as the previously configured global database name or pluggable database name.
