We are a IMS TM shop.  IMS has many dependant regions (each in it's own 
address spaces).  Each night we bounce the regions for DR purposes and 
some twice for another purpose.  Because the regions use cross memory 
services the ASIDs can not be reused.  We IPL every Sunday in part due to 
the IMS systems (we also have a test IMS in the same system). 

We are z/OS 1.8 so we do not have the health check you mention.  Is there 
a way to display the available ASIDs at the end of the week to determine 
how many ASIDs we would have to add to be able to IPL only once a month?

Are there any IMS TM shops out there that only IPL once a month or once a 
quarter?

That check is for depletion of ASIDs.  It has nothing to do with CPU creap
for long running address spaces or the system in general.
