In a manual I read the below statement :
If your application program is using the INVOKE WEBSERVICE command many times, it is recommended that you either use different channels on each call to CICS, or ensure that all the important data from the first request is saved before making the second request.
So lets say I create a requester Webservice with XYZ tranid and operation A.
And I need to use it like a batch mode, say for 5 customers i need to fire the webservice 5 times one after the other, so do i need to create different channel for each request fired ? Also, how is concurrency maintained in case of CICS requester service ?
