InfoSphere Information Server engine tier (DataStage, effectively) supports active-passive high-availability configuration. Does InfoSphere MDM also support high-availability configuration and, if so, where is this documented?

Seems that the answer is "yes". One document is here: [url]https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/Wa5aceb7894e2_4b94_9afe_4baab9274313/page/Achieving+high+avail ...

So the next question is...

Does anyone have an example of this in production?

Even in the Knowledge Center (once I'd figured out what to search for!) http://www-01.ibm.com/support/knowledgecenter/SSWSR9_11.3.0/com.ibm.swg.im.mdmhs.release.install.doc/Topics/t_InstallingHighA ...

It's good that you can answer your own questions! MDM and Info Server have similar bundled components like WAS and DB2, so, yes it is supported. We do not yet run high availability but may in the future.

There is an option to license MDM using Resource Value Units (RVU) instead of Processor Value Units (PVU), in which case there are no extra MDM software license costs when you increase hardware or take advantage of high availability.

I don't believe there's any choice but RVU licensing for MDM these days.
