Check the consistency of definitions.
The CHECK command performs a cross-check of a group, list, or lists of resource definitions, and should be used before the resource definitions are installed.
It checks that the resource definitions within the group or lists are consistent with one another.
For example: for each TRANSACTION in the list being checked, a check is made that the named PROGRAM definition exists in one of the groups. The success of the check does not necessarily mean that the PROGRAM is available to the running system.
Lists should be checked before being used to initialize CICS® during an initial or cold start (when the list or lists are specified in the GRPLIST system initialization parameter).
A group should be checked before you use the INSTALL command to install it on the running CICS system.
A group can be checked before you use the ADD command to add the group to a list. (The group might not be self-contained, in which case there is no point in checking it alone. Put it into a list with the groups containing related resource definitions.)
You can use the CHECK command from a DISPLAY panel.
