Configure APPC/MVS. This is an IBM program that is available with the MVS operating system, but has to be configured separately. It is a service that extends LU 6.2/APPC functionality to DFM and other programs in an MVS system. You define APPC/MVS start parameters in system PARMLIB member APPCPMxx (for example, SYS1.PARMLIB(APPCPMxx)). Among other items, the start parameters identify the Local LU (SNA Server's Remote LU).
The following is an example of the basic LUADD definition that should be included in SYS1.PARMLIB.APPCPMxx.
LUADD
---> ACBNAME(REMTLU) /* LU NAME
BASE /* DESIGNATE THIS LU AS BASE LU
TPDATA(SYS1.APPCTP) /* APPC/MVS VSAM TP data set
SIDEINFO DATASET(SYS1.APPCSI) /* APPC/MVS VSAM SI data set
