DNS search domain (i.e.,
ibm.com)
* MTU (optional, default =
1492, suitable for most
environments)
* TCP/IP stack name (only
needed if multiple TCP/IP
stacks are configured/active
on the z/OS system)
Update the z/OS TCP/IP profile:
* Configure zCX DVIPAs (IPv4
and optionally IPv6) by
using VIPARANGE statements (ibm.co/2W5x8t2).
The DVIPA must match zCX
server configuration (must
match the z/OSMF workflow configuration in Step
1). The same VIPARANGE
statements should be replicated across all systems in
the sysplex that you want to
start this zCX instance on.
* EZAZCX interface is created
when the EZASAMEMVS
(samehost) interface is
created. When using
DynamicXCF or enabling IUTSAMEH for
Enterprise Extender both
EZASAMEMVS (samehost)
and EZAZCX interfaces are
dynamically created and
started. If you're not using
Dynamic XCF or Enterprise
Extender, you must manually define (dev/link/home)
IUTSAMEH (which will also
create EZAZCX).
Update the OMPROUTE profile:
* Updates for zCX Dynamic
VIPAs being used. They're the
same as other DVIPAs. Use
wildcarding where possible
to simplify configuration.
* Remember to propagate
these to all other systems
in the sysplex that this zCX
instance may be started on.
Configure the IPSec policy. If
you have IP Filters defined, you
need to ensure that you permit routed and local traffic for
these DVIPAs.

Control the VIPARANGE
DVIPA creation through two
SERVAUTH profiles:
* EZB.MODDVIPA.sysname.
tcpname
* Limit who can create a VIPARANGE DVIPA in general
* EZB.MODDVIPA.sysname.
tcpname.resname
Limit who can create a specific VIPARANGE DVIPA:
* VIPARANGE DEFINE
255.255.255.255 10.10.10.1
SAF APPL1

*
*

*

Profile: EZB.MODDVIPA.
sysname.tcpname.APPL1
If either of these two profiles
are enabled, the user ID associated with the zCX started task will require READ
access to these profiles.
If these profiles aren't
enabled, the user ID associated with the zCX started
task must be UID(0) or have
READ access to the BPX.
