Hi, While I don’t have access to Tmon, I am amazed that it doesn’t display the Dispatcher Task Summary Table the same as Omegamon does. This display is fundamental to any CICS monitor as this gives a list of all the tasks that are currently dispatched. This table displays all the Tasks currently dispatched in CICS (both System and User) and both the Resource type and Resource name for each task. These two 8 byte fields are taken from each Tasks DTA (Dispatcher Task Area) and these live in the Dispatcher Domain.
I would consider that when you get your problem, issue a CEMT PERFORM DUMP. Then load the dump into IPCS and issue a VERBX command of DS=1 This should give you the Dispatcher Task Summary Table and from there you can see what your tasks are waiting on.

The task is shipping record to another CICS region. So I guess first maybe the cics setting have some problem, second the program in another region response slowly. Is it possible CICS setting problem? At 2011-03-02 04:05:24，"Pearce, Colin E" <colin.pea...@baml.com> wrote: >Hi, > >ZCIOWAIT defines the type of Resource the task is waiting on.
