J2EE Problem: Memory and CPU are rising to 100% sporadically

We are running Enterprise portal SP17 on Windows 64 bit server and Oracle 10i. We are now seeing memory and cpu spikes in production at 100%. Portal is not usable at times for 30 minutes+. It then usually recovers.

We reviewed vm settings such as heap size and garbage collection.

Please provide some assistance on possible causes.

    Hi Stephen,

    Try to tune your -Xmx and other JDK settings . Check your JDK version (java -fullversion) and see if there are any OSS notes on this JDK. Also sometimes it makes sens to check if the debug mode has been activated and switch it off,

    Regards,

    Mike
