The formatting of this information varies by platform.
%c The copy number of the backup piece within a set of duplexed backup pieces. If you did not duplex a backup, then this variable is 1 for backup sets and 0 for proxy copies. If one of these commands is enabled, then the variable shows the copy number. The maximum value for %c is 256. %d The name of the database. %D The current day of the month (in format DD) %F Combination of DBID, day, month, year, and sequence into a unique and repeatable generated name. %M The month (format MM) %n The name of the database, padded on the right with x characters to a total length of eight characters. (AKA: Porn star alias name) For example, if the scott is the database name, %n= scottxxx. %p The piece number within the backup set. This value starts at 1 for each backup set and is incremented by 1 as each backup piece is created. Note: If you specify PROXY, then the %p variable must be included in the FORMAT string either explicitly or implicitly within %U. %s The backup set number. This number is a counter in the control file that is incremented for each backup set. The counter value starts at 1 and is unique for the lifetime of the control file. If you restore a backup control file, then duplicate values can result. Also, CREATE CONTROLFILE initializes the counter back to 1. %t The backup set time stamp, which is a 4-byte value derived as the number of seconds elapsed since a fixed reference time. The combination of %s and %t can be used to form a unique name for the backup set. %T The year, month, and day (YYYYMMDD) %u An 8-character name constituted by compressed representations of the backup set number and the time the backup set was created. %U A convenient shorthand for %u_%p_%c that guarantees uniqueness in generated backup filenames. If you do not specify a format, RMAN uses %U by default. %Y The year (YYYY) %% Specifies the '%' character. e.g. %%Y translates to %Y.
