Nice Introduction to WLDF Watch/Notifications

James Bayer has a simple hands-on video on setting up WLDF watches and notifications in WLS.

WLDF enables you to dump diagnostic images or send out JMX/Email notifications when any metric of your interest crosses a configured threshold. There's more to it, but here is a good start that will catch your interest!

Oracle Enterprise Manager FMW Control versus Oracle Enterprise Manager Grid Control

I have had questions from customers on what comes extra within our EM Grid Control offering above and beyond our EM FMW Control.

EM FMW Control 11g is for managing and monitoring one single FMW Farm/ WLS Domain. If your topology comprises of multiple FMW Farms/Weblogic domains, you cannot use a single FMW Control to manage all of them at one place.

This is where EM GC 11g adss value. Apart from being a single management and monitoring portal for several FMW farms, EM GC 11g also allows you to monitor and manage non-middleware software such as OS resources, JVM, Database. With access to much more metrics than the EM FMW Control, it adds more value in Diagnosability and End to End Visibility.
Please refer to this link for details.

weblogic.socket.MaxMessageSizeExceededException: Incoming message of size: '10000080' bytes exceeds the configured maximum of: '10000000' bytes for protocol: 't3'.

If you are using BPEL Client APIs against WLS 9.2, and if you run into this exception, pass the following JVM argument to get things going,

-Dweblogic.MaxMessageSize=value

Make the value high enough for all that data to come through and you should be good.
