before DVM termination, wait for seconds which defined in CLIENTQUIESCEDELAY until there are no PSB scheduled with DVM.

DVM v1.1

IMS v13

With above env, we issued

/P AVZS

to terminate DVM while PSB is still scheduled.

Then, it caused U3398 error of that application.

We believe that termination command should wait till application will be stopped, or at least wait for a while, but after issued termination command, it caused U3398 error immidiately.

we set CLIENTQUIESCEDELAY as 60 because we expected that DVM will wait 60 seconds before shut-down, but according to DVM L2, CLIENTQUIESCEDELAY is not applicable for IMS.

DVM engineer said that "You will have to write an AHA (Enhancement

Request) so that on the DVM Shutdown it will have DVM check to see that there are no PSBs scheduled before disconnecting from IMS."

We need a design change so that DVM allows currently executing application programs to complete processing, just like the default specification ("MODE(QUIESCE)" option) of -STOP DB2 command of Db2 for z/OS.
