I’m an experienced Cloud/Oracle Applications/DBA Architect with more than 15 years of full-time DBA/Architect experience. I have gained wide knowledge on Oracle and Non-Oracle software stack running on-prem and on Cloud and have worked on several big projects for multi-national companies. I enjoy working with leading-edge technology and have a passion for Cloud architecture, automation, database performance, and stability. Thankfully my work allows me time for researching new technologies (and to write about them).

The control file includes:
– Database name
– Names and locations of associated datafiles and redo log files
– The timestamp of the database creation
– The current log sequence number
– Checkpoint information
To work with RMAN, you must configure several things, which can be default backup type (disk or tape), the number of channels you want to use, and the degree of parallelism.
When you are testing it on your personal system, you probably can get by with RMAN’s default configuration settings. However, for production jobs involving sophisticated backup strategies, you need to customize RMAN’s configuration settings to fulfill all your requirement. You can configure different backup retention policies, for example, for different databases.
