Defining all DFSMShsm hosts in a multiple-host environment

In a multiple DFSMShsm host environment, ensure that the host identifier for each host is unique by considering how you specify the HOST=x keyword of the DFSMShsm startup procedure. x represents the unique host identifier for each host. For details about specifying the HOST=x keyword, see HOST=x.

If you choose to use a single startup procedure in starting multiple DFSMShsm hosts in a single z/OS image, you have two alternatives to identify these startups for subsequent MODIFY commands:

S procname.id1,HOST=B,HOSTMODE=MAIN,other parms
S procname.id2,HOST=C,PRIMARY=YES,HOSTMODE=AUX,other parms

(The common procedure should specify PRIMARY=NO, so that you only have to override it only for the one primary host.)

S procname,JOBNAME=id1,HOST=B,HOSTMODE=MAIN,other parms
S procname,JOBNAME=id2,HOST=C,PRIMARY=YES, HOSTMODE=AUX,other parms

If you need to issue the same command to multiple DFSMShsm hosts started with identifiers that have the same set of leading characters, you can use an asterisk wildcard with the MODIFY command:

F id*,command
