Thanks for reply, I run the query for number of execution bigger than 50 and
find out few tables in the list, my question is if for example one table
executed more than 100 times can we pined the table into memory, so if YES
what about all the DML on this table.
Thanks

Hamid,
Madhu is right. But comination of execution and load will be more practical
.Run following query and see number of executions...
select substr(c.owner,1,5)"OWNER",substr(c.name,1,25)"name",
round(c.sharable_mem / 1024) K,
c.loads,
c.executions,
c.kept
from v$db_object_cache c,
sys.obj$ o,
sys.user$ u
where kept = 'NO'
and u.name = c.owner
and u.user# = o.owner#
and o.name = c.name
-- and o.type in (7, 8, 9)
order by 4,2 desc
/
Once you decide to pin run following through a sql file at the time of
startup script for database...(just an extract for your guidance)
EXECUTE SYS.DBMS_SHARED_POOL.KEEP('SYS.DBMS_APPLICATION_INFO');
EXECUTE SYS.DBMS_SHARED_POOL.KEEP('SYS.DBMS_DESCRIBE');
EXECUTE SYS.DBMS_SHARED_POOL.KEEP('SYS.DBMS_LOCK');
EXECUTE SYS.DBMS_SHARED_POOL.KEEP('SYS.DBMS_OUTPUT');
EXECUTE SYS.DBMS_SHARED_POOL.KEEP('SYS.DBMS_STANDARD');
EXECUTE SYS.DBMS_SHARED_POOL.KEEP('SYS.DBMS_UTILITY');
EXECUTE SYS.DBMS_SHARED_POOL.KEEP('SYS.STANDARD');
execute sys.dbms_shared_pool.keep('APPS.FND_DCP');
execute sys.dbms_shared_pool.keep('APPS.CSTPPWMX');
execute sys.dbms_shared_pool.keep('APPS.CSTPUTIL');
execute sys.dbms_shared_pool.keep('APPS.AP_APPROVAL_PKG');
execute sys.dbms_shared_pool.keep('SYS.PSTUBT');
exit;
HTH,

Hamid,
what happens , if an object is getting executed once in a while but takes
huge sharable memory, we may not be getting full use of pinning it in the
shared pool, except wasting the memory, So we need to consider the number of
executions also. if the number of executions are high for any object/SQL,
its good idea to keep it in shared pool.

Hi List,
I have run some scripts for Tune up shared pool,here is the result of one
script which i run :
Script:
SELECT name,sharable_mem
FROM v$db_object_cache
WHERE sharable_mem > 10000
AND (TYPE = 'PACKAGE' OR TYPE = 'PACKAGE BODY' OR
TYPE = 'FUNCTION' OR
TYPE = 'PROCEDURE')
AND KEPT = 'NO'
ORDER BY 2 DESC
here is the result:
NAME SHARABLE_MEM
----------------------------- --------------------------
DBMS_JAVA 56373
DBMS_STANDARD 24405
DBMS_UTILITY 24212
DBMS_SPACE_ADMIN 20832
DBMS_UTILITY 20508
DBMS_JAVA 15189
DBMS_OUTPUT 13063
DBMS_APPLICATION_INFO 12461
DBMS_SHARED_POOL 11148
DBMS_SHARED_POOL 10648
Question is, do i have to pin all of these objects in my shared_pool or NOT?
Thanks
