Installing the DFHCLNT and DFHIPECI resource groups

For general Client support, you must install the CICS-supplied resource definition group, DFHCLNT, which includes definitions of the CICS® on System/390® internal transactions, CCIN and CTIN, and of the programs they use. CCIN allows Clients to pass information to the server, such as the client code page to be used for data conversion between ASCII and EBCDIC. CTIN is required to install remote definitions of Client virtual terminals.

If you want to use ECI over TCP/IP, you must install the DFHIPECI CICS-supplied resource definition group, which includes definitions of the internal CICS transaction, CIEP, and CIEP’s associated program, DFHIEP.

The DFHIPECI resource group is included in the default CICS startup group list, DFHLIST.
