CEMT (Runtime Resource Management)

The Runtime Resource Management (CEMT) transaction allows you to examine and change, while the region is running, the CICS® system resource definitions that were initiated at startup.

This transaction affects only the runtime environment. Any changes that are made to resource definitions by using CEMT apply to the current session of CICS. They are not saved, but are replaced with the permanent resource definitions on the next restart, whether cold or auto.

CEMT allows a user to inquire on and to amend resource definitions, but not to insert new definitions or to delete existing ones.

To insert new definitions, or delete existing ones, you can use the resource definition online (RDO) commands cicsadd and cicsdelete.
