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?
