It sounds like you've already narrowed the problem down to trend analysis. We run OE on HP-UX and haven't been able to use some of these advanced OE management tools because they have never integrated well with that OS. But soon we will be moving to windows or linux and hopefully we will be able to use more of the OE tools. Please let us know how things turn out; I don't know much about that product. For identifying java processes (or any process) I typically use Process Explorer (from sysinternals). Then I configure it to show the some additional details below (typically I show file handles). Then if you click on each java process to select it, you can instantly see every file it is interacting with in Windows. This should easily be enough to distinguish admin server from another type of java process (nameserver, appserver, etc). Another thing to note is that admin server is typically easily recognized by its memory usage (working set). In contrast, the "nameserver" and the "sonic adapter" use much less memory. Appserver brokers are somewhere in between. I would sort all the java processes in Process Explorer by working set and then click on them from top to bottom in order to get to know them better. Insofar as admin server goes, it isn't uncommon for it to start running away with CPU. Often times there is a correlation with some "bad" thing that a developer did in OEE/OEM, - like click a link which is known to be "off-limits" (ie. viewing the database connection details for a single database user is "off-limits" because it gathers table/index statistics and that causes enormous CPU problems in admin server itself). The trick is to figure what features are "off-limits". It sounds like trend analysis may be one of those things that is problematic.
