Configuration Data Store Indexes for External OpenDJ

In production, the Configuration Data Store is usually an external OpenDJ server. In fact, most usually a pair of OpenDJ servers.

There is a section in OpenAM documentation - Preparing an External Configuration Data Store, which is useful . Read here.

The most important item is to set indexes on OpenDJ during configuration. See below:

In a recent deployment, I have forgotten to set the above indexes and the machine where OpenDJ servers were running on always hit 90-100% CPU. Very top-ish through the day.

After the indexes were set, the OpenDJ servers went back to normal.  Proper indexing does help.
