Hi,
In my database there is a big problem of shared pool getting
fragmented(ORA-4031). I know its due to some sql statements not getting
shared. I found some statements which are potential candidate causing
fragmentation.
There are about 6000 versions of same sql not shared due to use of table
aliases which makes statement different. Below is one of the example.
00000005ECD192B0 SELECT t3608.CURRENT_BUSDATE, t3608.BOM_DATE FROM
deldate0 t360800000005ECD192B0 WHERE t3608.NDAY_REGION = :"SYS_B_0"
00000005ED1E0C90 SELECT t66732.CURRENT_BUSDATE, t66732.BOM_DATE FROM
deldate0 t6600000005ED1E0C90 732 WHERE t66732.NDAY_REGION = :"SYS_B_0"
00000005ED5B2AE0 SELECT t110049.CURRENT_BUSDATE, t110049.BOM_DATE FROM
deldate0 t00000005ED5B2AE0 110049 WHERE t110049.NDAY_REGION = :"SYS_B_0"
00000005ED6C55C0 SELECT t310076.CURRENT_BUSDATE, t310076.BOM_DATE FROM
deldate0 t00000005ED6C55C0 310076 WHERE t310076.NDAY_REGION = :"SYS_B_0"
Similarly there are lot of other sql statements having more than 5000
version of same sql differing by table aliases.
Is there any way I can group those statements and get its count.
I am looking for report something similar below.
eg I am replacing all T<number> with T@ so the statements will match
and I can group together.
For eg
SQLTEXT
COUNT
-------
-----
SELECT t@.CURRENT_BUSDATE, t@.BOM_DATE FROM deldate0 t@ 6000
WHERE t@.NDAY_REGION = :"SYS_B_0"
SELECT t@.ID from parameter t@ WHERE t@.CALCI = :"SYS_B_0"
5000
SELECT t@.ISSSD from TRANSITION t@ WHERE t@.TRANS_I = :"SYS_B_0"
4000
Appreciate your help.
