Sequential (BSAM) devices

Terminal control information for sequential terminal devices is installed from the terminal control table (TCT).

CICS® installs sequential terminal resource definitions as follows:

Same TCT as last run. CICS installs the TCT and then modifies the terminal entries in the table by applying the cataloged data from the terminal control warm keypoint from the previous shutdown. This means that, if you reassemble the TCT and keep the same suffix, any changes you make could be undone by the warm keypoint taken from the catalog.
Different TCT from last run. CICS installs the TCT only, and does not apply the warm keypoint information, effectively making this a cold start for these devices.
