IBM not recommending 4-tier architecture anymore
Posted: Wed Jul 22, 2009 4:09 pm
In the 8.0 setup / admin guide IBM lays out several architectures, including the one my current client has selected - called the 4-tier architecture. This is where DataStage, Database, WAS and XMETA are all on different platforms.
In their admin class we recently learned that due to the performance impact they are now recommending that WAS and the XMETA database always be on the same system.
This explains why the only way we could get decent performance was to turn off XMETA logging and switch back to UniVerse-only logging via the uvconfig.
Just FYI for those of you planning on going to release 8 in the future.
