Been running it for 4 years now, no problems.  Just be aware that RLS is
the stripped down version of TVS.  RLS provides no transaction logging,
so if you are using RLS outside of say CICS, then you have to do
roll-your-own logging.  TVS provides logging, amongst other features.
You are parallel sysplex, right?

There is a PSP bucket for RLS, so make sure you are current on
maintenance.  z/OS 1.10 provided Multiple Lock Structure(MLS) support
for RLS, and the toleration maint for that was flakey for awhile, but is
fine now.

Subject: VSMA RLS

We are currently at zOS1.9 and are looking at implementing VSAM RLS.
Our 
maintenance is current.  We're wondering if anyone has had any issues
with 
RLS or cautions to share.  On or Off list is OK by me.
