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

But when ever i Click the button Fetch Last Page or press 'ALT+End' button a message box comes after a while saying: Then I started looking for the exact reason of this sort of problem in Google. When I realized there was no direct solution in the web, I started looking the PL/SQL Developer Software menu and found the ultimate solution. The reason of this problem is there is a parameter of maximum result set size in PL/SQL Developer Software which is by default set to 100 MB. To change this parameter you have to go to the following location: 1. Goto Edit Menu and click ' PL/SQL Beautifier Options '. A new window will open. 2. Click SQL Window of " Window Types ". 3. Now Change the value of "Maximum Result Set Size( 0 is unlimited)"  ...
