How to Delete Archivelog Using RMAN in Oracle

 

Recovery Manager (RMAN) is an Oracle Database client that performs backup and recovery tasks on your databases and automates administration of your backup strategies.

Start the RMAN executable at the operating system command line while connecting to a target database and, possibly, to a recovery catalog, as in the following examples:

% rman TARGET /       # operating system authentication
% rman TARGET SYS@prod NOCATALOG  # RMAN prompts for SYS password
% rman TARGET / CATALOG rco@catdb # RMAN prompts for rco password

set NLS_DATE_FORMAT=YYYYMMDD HH24:MI:SS
