RMAN Restoration Failed due to Error: RMAN-03002, RMAN-06026 and RMAN-06023

After a thorough search, I found the command to check INCURNATION. After changing the incurnation the restore command worked.

As the current incarnation key is nine and its not working, so i tried the previous one, i.e. Inc Key-8.

RMAN> reset database to incarnation 8;

After issuing this command restoration was successful.

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 session:
