I second this, very good point.
Do not attempt to use any logical replication solution to replicate large amounts of development data. You will basically crash it each time a large amount of data is refreshed and this happens frequently in most development environments. If you are using SAN-->SAN replication like SRDF or IASP-->IASP via PowerHA then it shouldn't matter.
For logical replication solutions I would ONLY replicate the code libraries and all necessary 3rd party code management metadata. Obviously there would be exceptions, but you need an understanding with your developers that large data refreshes need to be cooperatively handled (ie. holding the Mimix file entries or data groups then manually re-syncing the data to HA).

Good point, but I'd think that mirroring actual data in the development system would be less likely to be needed...instead you'd want source files and other objects...
What you'd want to mirrow would be your CMS data library...

One factor to be aware of with HA for Development areas running MIMIX. .
. . (you have probably thought about it, but let's point it out to
There are a lot more file refreshes (Copy-Files and Restores)
happening in the Development area. So the bandwidth for pushing the
mirrored data out to the HA box is different.
There are more blocks of time with huge data streams being pushed, and
less so granular transactions like you would see from production.
So among your choices in managing this is turning off Mimix when doing
file refreshes for developers.
