Format of RMAN Commands

The RMAN language is free-form. Keywords must be separated by at least one white space character (such as a space, tab, or line break). An RMAN command starts with a keyword corresponding to one of the commands described in Chapter 2, "RMAN Commands", followed by arguments and ending with a semicolon, as shown in the syntax diagrams. The following example shows an RMAN backup command:

BACKUP DATABASE;

A command can span multiple lines. For example, you can rewrite each keyword in the preceding command on a separate line as follows:

BACKUP
  DATABASE
;

You can insert a comment by using a pound (#) character at any point in a line. After the # character, the remainder of the line is ignored. For example:

# run this command once each day
BACKUP INCREMENTAL LEVEL 1 
  FOR RECOVER OF COPY      # using incrementally updated backups
  WITH TAG "DAILY_BACKUP"  # daily backup routine
  DATABASE;
