ARTTDQ manages transient data storage queues, it serves the functionalities required by EXEC CICS: WRITEQ TD, READQ TD and DELETEQ TD.

ARTTDQ publishes one service per declared queue as the name of the TDQueue suffixed by “_TDQ”:

A group of resources must be assigned to a single ARTTDQ server to avoid trying to publish the same service twice. This is checked at boot time and will generate error messages during the boot phase when not respected, but no action will be taken.

It is critical, and verified by TDQ server at boot time, that MIN and MAX number of servers are set to 1.

The extra partition TDQ data is lost after this server is down (e.g. stop or crash).
