Syntax Element | Description |
---|---|
%a | Specifies the activation ID of the database. |
%c | Specifies 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 | Specifies the name of the database. |
%D | Specifies the current day of the month from the Gregorian calendar in format DD . |
%e | Specifies the archived log sequence number. |
%f | Specifies the absolute file number. |
%F | Combines the DBID, day, month, year, and sequence into a unique and repeatable generated name. This variable translates into c-IIIIIIIIII-YYYYMMDD-QQ , where:
|
%h | Specifies the archived redo log thread number. |
%I | Specifies the DBID. |
%M | Specifies the month in the Gregorian calendar in format MM . |
%N | Specifies the tablespace name. |
%n | Specifies the name of the database, padded on the right with x characters to a total length of eight characters. For example, if the prod1 is the database name, then the padded name is prod1xxx . |
%p | Specifies 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 | Specifies 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 | Specifies 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 | Specifies the year, month, and day in the Gregorian calendar in this format: YYYYMMDD . |
%u | Specifies 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 | Specifies a system-generated unique filename (default). The meaning of %U is different for image copies and backup pieces. For a backup piece, %U specifies a convenient shorthand for %u_%p_%c that guarantees uniqueness in generated backup filenames. If you do not specify a format when making a backup, then RMAN uses %U by default.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 velog, %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 | Specifies the year in this format: YYYY . |
%% | Specifies the literal ' % ' character. For example, %%Y translates to the string %Y . |
