The binding is 60 times slower than compromising

Hello

I have a fairly serious problem using Toplink liaison. My setup is

TopLink 9.0.4.5
Oracle 10g EE 10.2.0.4.0 (64-bit, partitioning options, Data Mining and Real Application Testing)
Oracle JDBC Thin (11.2.0.1.0 or 10.2.0.4.0) driver

running in a Tomcat 5.5 environment.

Our usual configuration is with BindAllParameters = 'true', which is well in 99% of cases. But in a special case, which is the search functionality of our application (insurance agents management application),
a SQL is about 60 times slower with a binding, that without binding. I enclose the SQL at the end of the message, but what is quite special about it is that it uses a large amount of 'IN' clauses. I found an older version
display indicating that Toplink (or Oracle JDBC) has a problem with IN-clauses and binding. Can anyone confirm this?

As I said, the SQL part of a people search feature, so there are a lot of variants. Not all variations exhibit this behavior, so I guess, that Oracle probably uses different execution plans for the use of prepared statements or direct execution. Someone can he also confirm?

Finally, is it possible to record the execution inside the Tomcat application plan?

Thanks in advance for any help, as I said earlier, this problem is currently very critical, since we are 2 weeks before production,

Thorsten.

Here's the SQL example (with the bind variable already replaced):

You can disable the binding at the application level.

On your TopLink DatabaseQuery (ReadAllQuery) do.

query.setShouldBindAllParameters (false);
