In CICS, what are the storage limits of TS queues, TD queues and GETMAIN?
There are no particular storage constraints on these items -- however, if using AUX TS the file size of the DFHTEMP file provides the limitation, and if using TD to point to a file, then there is an equivalent limitation.
No particular limit is applied to GETMAINS, but if using storage below the 16MB line you will run into restrictions according to the size of the free areas.
