Olá pessoal.
Mais uma da séria “Vou postar aqui para não precisar pesquisar depois”.
Strings utilizadas para identificar um backuppeace no RMAN.
Syntax:
  %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.
Eu geralmente utilizo: %d_%Y%M%D_%I_%s_%U.rman
