Hi Nick, Datacenter is a place where all the servers are kept at one place.. mounted on racks.. The developers here run about 3 to 4 instances of weblogic on that server. We have installed oracle 10g r1 client. So far it was brought to my notice only when the server hung up. I have asked the developers to let me know when they use the server in future ... so that I can monitor when they use. I could only get a few warning messages from the logs... nothing much...
