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

Shared Pool Tuning: Cursor Tuning (Tuning Open_Cursors, Session_Cached_Cursors, Cursor_Space_For_Time)

Shared Pool Tuning: Cursor Tuning The three most important parameter for shared pool tuning are OPEN_CURSORS , SESSION_CACHED_CURSORS and CURSOR_SPACE_FOR_TIME. But most of the time we see that these two parameters SESSION_CACHED_CURSORS and CURSOR_SPACE_FOR_TIME are ignored or unused . OPEN CURSORS Open cursors take up space in the shared pool, in the library cache. OPEN_CURSORS sets the maximum number of cursors each session can have open, per session. For example, if OPEN_CURSORS is set to 1000, then each session can have up to 1000 cursors open at one time. V$open_cursor shows cached cursors, not currently open cursors, by session. If you’re wondering how many cursors a session has open, don’t look in v$open_cursor. It shows the cursors in the session cursor cache for each session, not cursors that are actually open.  To monitor open cursors, query v$sesstat where name= ’opened cursors current’ . This will give the number of currently opened cursors, by sessio...
