VMWare VCenter Server 4.1 & Oracle


We have VCenter Server 4.1 set up to use Oracle database (11r2 with the latest patches).

Everything works fine except the vcenter server starts very slowly, at the startup time one of the oracle processes eats near 100% of 1 CPU, it happens about 5-10 minutes every startup then almost no any CPU load.

There couldn't be a network issue – both VCenter and Oracle run as VMs on the same ESXi box.

We have 2GB RAM allocated for Oracle but EM shows it's more than enough – it never eats more than 1GB.

When the same VCenter used it's bundled MS SQL Standalone, everything started up fine. The database is small – a couple of the test servers in one cluster and about 40 virtual machines running on them.

VCenter OS: Win 2003 x64,
Oracle OS: OEL5

Is everybody facing the same problem with VCenter+Oracle?

It's really not what you want to hear but we're a big Oracle client but had to give up with our ~30 VC boxes when we moved them to Oracle due to similar odd problems (we had a lot of DB disconnections too). We've not had any problems since moving back to MSSQL, it's not that I'm a big fan either, it seems to be more stable.

Hope you get a better answer than this but I just wanted you to be aware of our problems.
