We have some limitations due to the size of CICS Commarea.
A google search shows questions asking how to have more than 64K. But I have not found how to get more than 32K.
Is the max CICS Commarea 32K? If not how can it be increased.
A CICS commarea is limited to 32K - 1, the maximum value that can be stored in a signed halfword.
There is no way to have a commarea larger than 32K - 1. One mechanism to get around this limitation is to use channels. There are also Redbooks on the subject.
