CICS® Configuration Manager provides many advantages over the resource definition online (RDO) transactions (CEDA, CEDB, and CEDC) that are provided by CICS. It is recommended that you no longer use these transactions at all; neither the CICS-supplied originals nor the replacement definitions described here. Instead, use CICS Configuration Manager to maintain your resource definitions. You can use CICS transaction security to prevent access to the RDO transactions; for details, see the CICS Transaction Server for z/OS® documentation.
In case you want to allow users to continue using these transactions, CICS Configuration Manager provides replacements for the CICS-supplied transaction definitions. The replacement definitions check whether the CICS Configuration Manager server or another user of these transactions (using the replacement definitions) is already using the CSD file. If the CSD file is in use due to either of these two situations, the transactions display the message CCV5372I, and then end. Otherwise, the transactions display the message CCV5371I, and then pass control to DFHEDAP, which is the program specified by the original CICS-supplied transaction definitions; the transactions then behave according to their original CICS-supplied definitions.
If you allow users to continue using these transactions, then you should replace their CICS-supplied definitions on all CICS regions that will be managed by CICS Configuration Manager.
Previous steps in the CICS Configuration Manager installation procedure have already replaced these transaction definitions on the following CICS regions:
