Weblogic Enterprise Manager Fusion Middleware Control 12c takes too much time to login
Recently I have come across a strange situation in Weblogic EM Control login. Problem Summary- Environment- Oracle WebLogic EM Control 12c Enter the EM control URL in web browser- http://192.168.0.141:7001/em Provide username/password Click Login Now a message shows- "Login Successful .... Redirecting" and it takes too much time (sometimes 30 secs to 2 minutes) to show the landing page Changes As the number of fmwc monitored targets increases, the login times goes up as well. Cause fmwc discovery is always performed as part of login. For installations with thousands of targets, fmwc discovery may take 45-60 seconds. This time is expected because EM discovery mbeans need to be invoked for every target. Solution Solution is to cache the discovery results in the servlet context and use it for subsequent logins. This discovery result will be shared by all the fmwc users. This will still require the entire discovery to be done...
