Top SQL Ranking/SQL_ID for Load test.

2010-11-30  张林 

We noticed that the SQL_ID for the Top SQL for 10g and 11g are very much different even they might have almost identical SQL statement.

We might have difficulty in the near future to compare the performance between 10g and 11g.
for 10g
10.2.0.4.0 64bit(ojdbc14-10.2.0.4.jar + 10G database):
b0ffw4gqmj634 select synchronization_lock_datetime from it_entity_lock where extended_entity_name = 'IT_POOL' and primary_key_string = :1 for update
 
for 11g 11.2.0.1.0  64bit (ojdbc6-11.2.0.1.jar + 11G database):
bjkc1zp7z6q6n select synchronization_lock_datetime from it_entity_lock where extended_entity_name = 'IT_POOL' and primary_key_string = :1 for update

Can who kindly tell us:
1) If the binary for Application program to test 10g and 11g are different from each other ?
2) are there any SQl changes to above Top SQLs ?
We are expecting the SQL_ID/Hash Value should always be the same under different version of compiler. 

Different JDBC driver version casue this.
