NimbostratusHi Ed
The easiest way we have found to do this is to create a page in Apache that checks the status of the OC4J application. It can do this by requesting a known piece of content. If it gets the content back as expected then the page just responds to a GET request with something like OC4JOK in the body. If not it doesnt return anything or gives an error message it will not return OC4JOK. You can then setup a HTTP monitor on the loadbalancer that looks at the page and in the Recieve String of the monitor put OC4JOK. If it finds this then everythign is ok if not then it will fail and take it out of the pool.
Hope this is what you were looking for.
cheers
Simon
