We run our EntireX services in batch (z/OS). When we migrate modified subprograms to production, the batch sessions often retains the old version in the buffer pool for some time. This can lead to runtime errors. Our only solution right now is to stop the job and resubmit it. This obviously affects our system availability.
I found a program USR0340P in SYSEXT which executes USR0340N. This seems to provide some scope for using an RPC call to USR0340N to flush the buffer for a specific program.
- has anyone tried to use USR0340N for this purpose?
- has anyone got a different solution to this problem?
