If you are sysadmin, sometimes you might find yourself dealing with Oracle backups.
Apart from taking oracle RMAN backup, you should also understand how to Delete the old backups from the RMAN catalog and from physical filesystem.
If you don’t properly delete obsolete and expired Oracle DB backup from the catalog, it will cause some unnecessary throw error message during backup and also it will take-up space at the filesystem level.
Also, it is not recommended to directly remove the RMAN backup files from the filesystem using Linux rm command.
This tutorial explains how to identify the backups that are obsolete and expired, and how to properly delete them from RMAN.
LDAP stands for Lightweight Directory Access Protocol.
LDAP is a solution to access centrally stored information over network. This centrally stored information is organized in a directory that follows X.500 standard.
The information is stored and organized in a hierarchical manner and the advantage of this approach is that the information can be grouped into containers and clients can access these containers whenever needed.
The OpenLDAP hierarchy is almost similar to the DNS hierarchy.
