Hello,
we have a 7.00 Portal on AIX 5.2, 64bit and DB2 V.8.2.2 with 8 CPUs and 20GB RAM. We installed three java instances and each with to servers nodes. For each server node we configured min/max java heap to 2048.
We had big problems before implementing the newest sdk verion. Now the portal is running stable, but during loadtests we got problems, with more then 750 users.
Question:
Is there a note for database (db2) parameters with j2ee?
We had problems with the JDBC Queries and Updates? How can I improve the performance?
Also, we had problems with Applocking (ServerInternalLocking)? Any idea how to improve performance?
Regards,
Alexander Türk
