How are resources managed?

CICS® includes a number of facilities that help you manage your resources once you have created them on the CSD.

The resource management transaction CEDA
An online transaction that allows you to operate on resource definitions held in the CSD. See The CEDA transaction tutorial and Resource management transaction CEDA commands.
The resource management utility program DFHCSDUP
A batch program that allows you to operate on and list the CSD offline. See CICS Operations and Utilities Guide.
The RDO command logs
Separate transient data queues that record information about resource definition. See CICS System Definition Guide
The CICS global catalog
A data set that is not used exclusively for RDO, but is used to record installed resource attributes for warm and emergency restarts. See CICS System Definition Guide.
CEMT
CEMT is a CICS-supplied transaction that you use to invoke all the master terminal functions. The master terminal program provides dynamic user control of the CICS system. By using this function, an operator can inquire about and change the values of parameters used by CICS, alter the status of the system resources, terminate tasks, and shut down the CICS system. See CICS Supplied Transactions.
SPI commands
The CICS system programming interface (SPI) commands are used to manage the CICS system and its resources. These commands, which provide you with a command-level equivalent to the function of the master terminal transaction (CEMT), fall into three categories:
  • Commands that retrieve information about a CICS resource or system element
  • Commands that modify the status or definition of the system or a resource, or invoke a system process
  • Commands that modify or expand system execution by means of exits.
