Defining resources
After you have installed CICS®, you must define and install all the resources that your CICS regions require to run user transactions.
For a list of resources, see CICS resources: listing, syntax, and attributes.
To know about how you can define CICS resources, see Ways of defining CICS resources.
If you want to use the Resource definition online (RDO) transaction CEDA to define resources to your CICS system, see CEDA - resource definition online for details.
