OAS 10.1.2 - Slow connection to Oracle 10gR2 DB

Question

Hi,
We have an application running on OAS 10.1.2.0.2 on Solaris 10 64bit edition. We have data sources configured to connect to a 10gR2 DB (10.2.0.4) using OCI drivers. When the application makes initial connection to the DB it takes 30 mins.... The application uses the OCI client library under <OAS_HOME>/lib directory. The server instance is started using the JDK bundled along with the app server.
We also have a separate Instant client installation 10.1.0.5 which is certified to work with OAS 10.1.2 and JDK 1.4.2_19 on the same environment. We have a written a Java program to test the DB connectivity through OCI... When we either use the OCI libraries on OAS or the instant client we encounter an error saying wrong ELF class: ELFCLASS64 error
We proceeded to execute the test program with -d64 switch to the java executable which cuased the program to connect instantly to the DB,
The question is the OAS, Solaris, Instant client all are 64 bit editions but the JDK that comes bundled with OAS does not accept -d64 switch and causes it to terminate immediately.
Can anybody tell me whether the JDK bundled with OAS 10.1.2 is 32 bit or 64 bit and does it cause performance or connectivity issues when trying to use along with 64 bit libraries.
Thanks
Karthik

Hi,
Do you have any LANG parameter at your environement variable ?.
if U have just remove it then stop your metadata+as including your 8i DB.
Then start all of them again & try to connect to your database.
If it helps it's okay, otherwise let me know so we can go further for some other solutions. it 'll be little bit hard but I 'm thinking of upgrade your DB will be necessary.
