APPC/MVS Instructions:

1. 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 IMS and other programs in an MVS system.
2. In SYS1.PARMLIB(APPCPMxx), define the IMS LU to APPC/MVS:

       LUADD ACBNAME(REMTLU)
           BASE
           SCHED(IMSA)            APPC/MVS transaction scheduler. This
   				       value must match in your IMS startup job.
           TPDATA(MS.APPCTP)      Permanent VSAM data set for TP profiles
           TPLEVEL(SYSTEM)        Search order for TP profiles
   

3. Add the IMSID keyword in the IMSCTRL macro to match the SCHED keyword in the LUADD statement above:

       IMSCTRL SYSTEM=(VS/2,(ALL,DB/DC),4.2),
       IMSID=IMSA    

4. Start IMS/APPC by specifying APPC=Y (default is NO) on the IMS startup procedure. You can use /START APPC if IMS is already up. This is just to start the APPC components within IMS DC.
5. In IMS startup job, ensure JCL symbolic parameter IMSID= matches the scheduler defined in SYS1.PARMLIB (this case IMSID=IMSA) This points IMS DC to the above PARMLIB entry.
