Dynamically make the resource definitions in the named group or group list available to the active CICS® system.

You can use single-resource install to install only the resources you require.
When applied to telecommunication and intercommunication resources, there are restrictions on the single-resource INSTALL command. The restrictions apply to resource definitions that are linked—for example, CONNECTION and SESSIONS definitions.
If you want to use single-resource INSTALL for TERMINAL and related TYPETERM definitions, you must install the TYPETERM that is referred to by a TERMINAL definition before you install the TERMINAL definition.
The same applies when installing groups containing TERMINAL and TYPETERM definitions; install the group containing the TYPETERM definition before you install the group containing the TERMINAL definition. Similarly, if you install a list that contains groups containing TERMINAL and TYPETERM definitions, the group containing the TYPETERM definition must be before the group containing the TERMINAL definition. Also, in a list containing groups of DB2® resource definitions (DB2CONN, DB2ENTRY, and DB2TRAN definitions), the DB2CONN should be defined in the first group in the list.
A CORBASERVER definition must be either in the same group as the DJAR definitions that refer to it, or in a group that is installed before the group containing those DJAR definitions.
If the named resource already exists in the active CICS system, the existing definition is replaced by the new one.
Replacement of an existing definition occurs only if it is not actually in use.
In addition, a message is written to the CEMT log, saying that the install completed with errors.
CEDA INSTALL can be performed from a console, using the MVS™ MODIFY command.
