It is totally unnecessary to shut down DB2 to get a consistent DFDSS
DASD backup. Check out DB2 SUSPEND and RESUME which is designed to
temporarily freeze DB2 activity with data sets in a consistent state for
precisely this purpose..

thanks Rob,
I familiar with stoping the RRS .
we have a weekly process which shutdown the DB2 subsystem for the DFDSS DASD
backup. there is no work done on the DB2 so it's not consider as a down time
for us.
beside this weekly backup we are also face (from time to time) reasons which
force us to start the DB2 .
there are more then 3 DB2 subsystem - and this the reason the ASVT are
running out.

The most common reason for DB2 address spaces to be marked non-reusable
these days is that they have a cross-memory bind to the RRS address space.
You *could* probably relieve the shortage by stopping and re-starting the
RRS address space - however there are implications to doing this while you
have active workload that could be using RRS services.
Do you shutdown your DB2 subsystems on a regular basis? If so - maybe you
need to consider if you still need to do this. The more often you shutdown
DB2, the more chance you have of chewing up the ASVT slots.

Subject: *IEA061E REPLACEMENT ASID SHORTAGE HAS BEEN DETECTED
Hi,
One of my lpar is is suffering from
*IEA061E REPLACEMENT ASID SHORTAGE HAS BEEN DETECTED
I notices that the DB2 STC are ended with :
IEF352I ADDRESS SPACE UNAVAILABLE
I'm familiar with the option to start AS with REUSASID=YES but DB2 isn't
start with the 'start' command and i don't know how to implement this with
DB2 subsys and if it's possible.
is DB2 STCs always leave a AS unreausable ? or maybe there is somthing I
can
do to avoid this.
the reason I asking it , is beacause i would like to avoid enlarge the
RSVNONR .
