Restricting Access/Connections to the Database

In order to restrict the connections to the database we can add some parameters in the sqlnet.ora file under ORACLE_HOME form where listener is running. This would make sure that sessions to the database are coming only from specific list of hosts, and any session from all other hosts is not allowed to connect to the database. Following are the parameters we can use for such restriction.

Archivelog Deletion Policy for RMAN

RMAN archive deletion policy is used to set when we want archived logs to be deleted when DELETE ARCHIVELOG command is executed from the RMAN prompt, or if we are using Fast Recovery Area for archived logs, and are not deleting archived logs manually and relying on automatic feature of Oracle for deletion of archived logs (archive deletion would happen automatically if space crunch is observed by Oracle under fast recovery area).
