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?

It has nothing to do with CPU creap for long running address spaces or the system in general. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
