You may be seeing FMWC EM console targets down or slow response times when accessing /em and navigating through FMW Control. You may attempt to access DMS to troubleshoot that issue, or you may be following the following guide to access DMS directly:

Either way you find this issue, the results are the same, when accessing DMS via you get the following error:

URL returns 500 Internal Server error

It has been confirmed that WLS, JDK, and FMW products are all installed in a certified manner between versions and all system requirements met. It is known for an unexpected JDK version or lack of system resources to cause similar issues.  In this case, a review of the "bi_server1.log" (with an OBIEE installation) provided the following error stack leading to an issue with the DMS component:

<Error> <HTTP> <hostname> <bi_server1> <[ACTIVE] ExecuteThread: '16' for queue: 'weblogic.kernel.Default (self-tuning)'> <> <> <a20b44d6996c76ae:-aca9d0d:14ed02c0faa:-8000-00000000000fa77d> <1438894721671> <BEA-101020> <[ServletContext@1080164538[app:DMS Application module:dms.war path:/dms spec-version:2.5 version:]] Servlet failed with Exception
