Control blocks

A command list table (CLT) is used by an alternate system when it takes over the running of CICS® from an active system. It holds the ID data for the JES system in use, data used to verify its authority to take over, and routing information. If there is more than one active system in two CECs, the CLT also holds VTAM® MODIFY commands, and messages to the operator (WTO) to complete the takeover. It is loaded during takeover, and deleted when processed.

See the CICS Data Areas manual for a detailed description of this control block.
