AS/400 IBM Network Station: Techniques for Deployment in a WAN
In addition, the AS/400 TCP/IP Autoconfiguration: DNS and DHCP ,
SG24-5147, is available online at: www.redbooks.ibm.com
As a result of the previous steps, the IBM Network Station users at the
Rochester remote site boot from their
local SYSAS4 AS/400 system which
was
replicated from the master copy SYSAS3 AS/400 system at the central
site. Because preference files were copied from SYSAS3 to SYSAS4, all IBM
Network Station users in the Rochester location see a default desktop that
contains the custom 5250 and NC Navigator menu bar buttons. In addition,
users who are members of the grp3270 l also see a 3270 button on their IBM
Network Station desktop.
7.3 Summary
The information in this chapter includes as-is , non-supported techniques for
replicating an IBM Network Station Manager Release 3 environment from one
AS/400 to another when implementing multiple AS/400 boot servers. In
review, some crucial tasks when using one of the replication techniques in
this chapter are:
• Develop an implementation plan and draw or revise a network diagram.
• Determine whether the Release 3 separation of servers function will be
used. For example, will you be using a central server for authentication
and the remote sites for base code serving or will each remote server fulfill
the authentication, terminal configuration and base code server roles? If
you are using DHCP, consider the location of the server. Also, there may
be a requirement to install multiple DHCP servers. Refer to the manual,
TCP/IP Configuration and Reference , SC41-5420.
• Review the desktop customizing needs of the remote users. If the remote
servers are providing the authentication server function, are there certain
system level, group, or even user defaults which can be set on the
master
copy
so that these preferences can be replicated initially to all remote
AS/400 boot servers?
• Are the remote servers and the source
master copy system at the same
OS/400 levels? The techniques in this chapter were tested in an
environment where both the source and the target systems were at V4R3.
If they are not at the same level, ensure that you verify that pre-requisite
PTFs are installed as directed in the previous sections. In addition, the
steps involving the saving of products or files must reflect the proper target
release level.
• If using these replication techniques, please test them in your own
environment before using them to create production systems.
