Every Oracle Fusion Middleware Administrator wil recognise the complaint: EM Console is slow. The reason for this can differ, but it is most often caused by lots of composites which are deployed on your SOA-INFRA and the Admin Console collecting metrics on all of them. Oracle Support discusses this issue in Doc ID 1423893.1, in which they explain how to set various mbeans to cache certain EM metrics. Settings these mbeans has to be done through the cumbersome mbean tree. But what if I told you MyST can do it for you?

This post is part of a Series in which Maarten Tijhof and I explore the inner and hidden parts of Rubicon Red MyST Studio which might come in handy at times.

In Oracle Fusion Middleware SOA Suite, the Enterprise Manager is used to show composites, metrics and (if desired) even the composite instances with or without payload. Collecting all these values puts a lot of load on your AdminServer and it is not uncommon for the Enterprise Manager Console to take a very long time to log in. Especially when the amount of composites and the payload grows, logging in to EM can become quite a pain.

Oracle addresses this issue by giving you certain mbeans to tune the EM Console. Most of these mbeans concern caching certain displayed results so that the login becomes much faster after building up the cache. Unfortunately, the first user to log in is still stuck with the slow login time, as this time is used to build the actual cache.

Of course you can manually set the mbeans without MyST, just use Doc ID 1423893.1 and follow the steps to add the appropriate mbean values in the Mbean browser. You’ll be looking for the emoms.props bean. Once you found it, hit ‘properties’ and some default key-value pairs are shown.


As described in the Oracle Documentation, you’ll need to add some fixed key-value pairs to the list shown above. You can do this using ‘setProperty’ on the ‘Operations’ tab. Repeat the invocation for each of the four key-value pairs described in the document and you should be all set. Note that this has to be done for each EM Console you wish to tune, so you can imagine why this is cumbersome.

However if you have MyST, all you need to do is add these properties to the Global Variables of the Platform Blueprint. This way, you only have to set the desired tuning values once and they will be used on all models that inherit from that blueprint. Simply click the blueprint and hit ‘Edit Configuration’. In the Global Variable section, press ‘bulk edit’ to add the properties listed below. Hit ‘save’ or ‘save and commit’ on your blueprint to save your changes, you no longer have to save the bulk change seperately. The list below describes the properties you need and what they do:

--enable caching for FMW Discovery data--

--sets how long the cache is valid in millisec, below is 30 days--

--sets a timeout for a running discovery when a new user logs in

--skip certain metrics (and big SQL statements) so login is faster--

The tuning of the EM console is now added out-of-the-box for each new environment you provision based on this blueprint! But what about existing models?

First, select your model and run the ‘update’ command. Although you will not see any changes in the log, this changes your MyST instance so that it will use the new global variables in the future. In case you’re dealing with a 12c environment, you need to run a custom action on the same model and use ‘configure-soa’ as the action. Don’t forget to hit the ‘tab’ key, otherwise the command won’t stick. In 11g environments this step can be skipped because the ‘configure-soa’ command is part of the ‘update’ procedure.


Hit Execute and you should see the following in the MyST logs:


And you’re done! Note that these instructions closely resemble the method of setting mbeans on your MyST environments, as described by Maarten. However, setting mbeans has to be done on the ‘SOA Product’ section in MyST, whereas the EM Tuning parameters have to be added to ‘Global Variable’ section.

We hope these instructions will save you a lot of time, clicking though the mbean browser and especially logging into EM.
