Background Processes and Listener in Oracle 18c

In this post we can see that how many background processes will come after starting the Oracle 18c Database on virtual box. Also we can create listener in Read Only Home to connect the database remotely with the help of tns entry.

Let me start the newly created 18c Database.

Configured the Listener Manually or with netmgr. Notice that it’s under Read Only Home path.

Now we need to create the tnsnames.ora.

Now we are connecting the newly created 18C database remotely with the help of TNS

Below are the some background processes in Oracle 18c database.

[oracle@18c admin]$ ps -ef|grep tns
