Manoj I checked and founnd the Cursor_sharing is exact and will use the Force. Actually in the trace which is created with Bind and Waits = to true shows that all of the Sql called are having "sql*net message to/from client" Do you think that this has link to any network issue. I am also having some query where the trace shows the binds variable and below is one from the trace file. First is the TKprof output and second is content from trace itself. The tkprof show that Parsing is done for each rows <<<<<<<<<<<<<<<TKPROF>>>>>>>>>>>>>>>>>>> SELECT NVL(L.T_VALUE,S.R_VALUE) FROM L_TRANSLATIONS L,SUB S WHERE S.ID = L.SUB_ID (+) AND L.L_TYPE_GR_ID (+) = :b1 AND S.ID = :b2 call count cpu elapsed disk query current rows ------- ------ -------- ---------- ---------- ---------- ---------- ---------- Parse 3262 0.36 0.38 0 0 0 0 Execute 3262 1.86 2.48 0 0 0 0 Fetch 3262 1.28 1.40 0 36274 0 3262 ------- ------ -------- ---------- ---------- ---------- ---------- ---------- total 9786 3.50 4.27 0 36274 0 3262 Misses in library cache during parse: 1 Optimizer goal: CHOOSE Parsing user id: 722 (SANJAY) Rows Row Source Operation ------- --------------------------------------------------- 1 NESTED LOOPS OUTER 1 TABLE ACCESS BY INDEX ROWID SUB 1 INDEX UNIQUE SCAN (object id 50109) 1 TABLE ACCESS BY INDEX ROWID L_TRANSLATIONS 1 AND-EQUAL 5 INDEX RANGE SCAN (object id 38679) 4 INDEX RANGE SCAN (object id 50945) Rows Execution Plan ------- --------------------------------------------------- 0 SELECT STATEMENT GOAL: CHOOSE 1 NESTED LOOPS (OUTER) 1 TABLE ACCESS GOAL: ANALYZED (BY INDEX ROWID) OF 'SUB' 1 INDEX GOAL: ANALYZED (UNIQUE SCAN) OF 'SUB_PK' (UNIQUE) 1 TABLE ACCESS GOAL: ANALYZED (BY INDEX ROWID) OF 'L_TRANSLATIONS' 1 AND-EQUAL 5 INDEX GOAL: ANALYZED (RANGE SCAN) OF 'LTR_IDX_3' (NON-UNIQUE) 4 INDEX GOAL: ANALYZED (RANGE SCAN) OF 'LTR_IDX_2' (NON-UNIQUE) Elapsed times include waiting on following events: Event waited on Times Max.

Thanks manojk.jha@xxxxxxx wrote: HI All, The high no. of parsing ( in ur case no. of parse =no. of execute = no. of fetch) is due to cursor are not being shared. Please supply SQL_text and explain for further analysis. What I hopes is application is using hard coded value , thus limiting the cursor_sharing. In ur system check the cursor_sharing parameter. If the its value is similar or exact change to force for forms applications.
