Queues
There are two types of queues TSQ and TDQ.
TSQ can be used as scratch pad in main memory.
You can write as much as you want in TSQ and they will be
available to all the transactions that are aware of the
queue name.
TSQ is primarily used to share huge amount of information
across the transactions
The name of every TDQ must be defined to CICS in a
Transient Data Definition (TDD) entry before the queue is
used by an application program.
Unlike temporary storage queues, TDQs cannot be dynamically
created by an EXEC CICS WRITEQ command from an application.
TCTCA, TWA, CWA
TWA – Transaction work area – One per task - Work area
associated with the task.
TCTUA – Terminal Control Table User Area – Work area
associated with a terminal and defined as one per terminal
in TCT.
CWA -- Common work area – System work area defined by
system programmer in SIT. (System Initialization Table)
We can use TWA, TCTUA and CWA for sharing the information
across the transactions.
