Starting the APPC/MVS address space

Use the START APPC command to start the Advanced Program-to-Program Communication/MVS (APPC/MVS) address space.
 
S APPC,SUB=MSTR[,APPC=(nn[,nn]...[,L])]
 

The parameters are:

APPC,SUB=MSTR
Invokes the APPC/MVS procedure and creates the APPC/MVS address space.
APPC=
Indicates which APPCPMxx parmlib members APPC/MVS is to use. The default member is APPCPM00. If you specify only one parmlib member, you do not need to enter the parentheses.

The APPCPMxx members can reside in SYS1.PARMLIB or any other parmlib data set that is specified on an //IEFPARM DD statement in the master scheduler JCL. However, APPC/MVS cannot process data sets specified in the master scheduler JCL until the operator enters a SET APPC command. For information about how to specify configuration information in a parmlib data set other than SYS1.PARMLIB, see the description of starting APPC and ASCH in z/OS MVS Planning: APPC/MVS Management.

L
The system will display parmlib statements on the operator's console as it processes them.

Example 1:

START the APPC/MVS address space with parmlib member APPCPM00.
S APPC,SUB=MSTR

Example 2:

START the APPC/MVS address space with parmlib member APPCPM01.
S APPC,SUB=MSTR,APPC=01

Example 3:

START the APPC/MVS address space with parmlib members APPCPM03 and APPCPM06, and list the parmlib statements as the system processes them.
S APPC,SUB=MSTR,APPC=(03,06,L)
