Pass data more than 32kb other than COMMAREA

Hi Friends,

I am passing data from one cics prog to another, using DFHCOMMAREA.

Need to pass data more than 32kb so can't use DFHCOMMAREA, anymore (if i m not wrong dfhcommare limit is 32kb. Our cics ver is CICS 6.5, I guess).

I am thinking of using TDQ, now. Very quick question on TDQ usage.
My 1st prog would write the TDQ which would be read by the 2nd prog.
Now there is a possibility that there can be multiple instances of the transactions running simoultanously. That means there would be multiple instances of 1st prog writting data in TDQ simultanously, so the 2nd prog would not be able to read the data correctly, incase it reads the TDQ in a sequence.

Any idea? Any suggestion? thanks !!!

better maybe TS queue

using as the key something like TERM_IDNT concatenated to the TRAN_CODE

Have you looked at 3.4 Enhanced inter-program data transfer: channels as modern-day COMMAREAs?

thanks for your suggestion on using container...
it seems every container is having a specific name.
my concern is if i got multiple occurance of cics transaction which writes in the same container (as the cics transaction invokes the same prog) would it be a prob for the second prog to read the data?

apprecaite your help!!thanks

Like the TS queues, the channel names that contain the containers can be devised as unique too....
