Opens and Closes URTs

To use system resources effectively under CICS, the Open and Close functions are performed by CA Datacom CICS Services. Unless you specify otherwise, CA Datacom CICS Services opens all URTs at CICS startup and closes all URTs at CICS shutdown. You can specify general exceptions through the System Generation Options Table (DBCVTPR) or explicitly invoke an open or close at anytime through online commands. In DBCVTPR, you can list URTs to be opened only when their use is required or only when you enter an online command to request the open.
