RMAN: Format Directives:

Format	Description
%a	Current database activation id
%A	Zero-filled activation ID
%c	The copy number of the backup piece within a set of duplexed backup pieces.bMaximum value is 256
%d	Database name
%D	Current day of the month from the Gregorian calendar in format DD
%e	Archived log sequence number
%f	Absolute file number
%F	Combines the DBID, day, month, year, and sequence into a unique and repeatable generated name
%h	Archived redo log thread number
%I	DBID
%M	Month in the Gregorian calendar in the format MM
%n	Database name, padded on the right with x characters to a total length of eight characters
%N	Tablespace name. Only valid when backing up datafiles as image copies.
%p	Piece number within the backup set. This value starts at 1 for each backup set and is incremented by 1 for each backup piece created. If a PROXY is specified, the %p variable must be included in the FORMAT string either explicitly or implicitly within %U.
%r	Resetlogs ID
%s	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. CREATE CONTROLFILE initializes the counter at 1.
%S	Zero-filled sequence number
%t	Backup set time stamp, 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	Year, month, and day in the Gregorian calendar in the format: YYYYMMDD
%u	An 8-character name constituted by compressed representations of the backup set or image copy number and the time the backup set or image copy was created
%U	A system-generated unique filename (default). %U is different for image copies and backup pieces. For a backup piece, %U is a shorthand for %u_%p_%c and guarantees uniqueness in generated backup filenames. For an image copy of a datafile, %U means the following: data-D-%d_id-%I_TS-%N_FNO-%f_%u For an image copy of an archived redo log, %U means the following: arch-D_%d-id-%I_S-%e_T-%h_A-%a_%u For an image copy of a control file, %U means the following: cf-D_%d-id-%I_%u
%Y	Year in this format: YYYY
%%	Percent (%) character. For example, %%Y translates to the string %Y
