Multinet to TCP/IP migration

[Gary_167]

Hello, does anyone have any experience in migrating from Multinet (4.3) to TCP/IP (5.4 or 5.5)? Is there any documentation from HP on this?

[Art Wiens]

I think you're on your own...but enough MULTINET SHOW commands should give you a good picture of what your IP config looks like. You can also wade through MULTINET_ROOT:[MULTINET]START_MULTINET.COM . Much of your configuration is in there.

Its a matter of configuring TCPIP to match after that.

can both applications be loaded at the same time or do i have to uninstall multinet before loading TCP/IP?

[Wim Van den Wyngaert]

Gary,

Never saw multinet but
1) applications may be linked with some olb/exe of it and may fail if multinet is not available. Relink them !
2) you should compare all timeout settings (e.g. keepalive) or get appl;ication hangs.
3) test test test

I don't imagine trying to "run" both products at the same time would yield "desirable" results! But you don't have to uninstall Multinet, just turn it off when you want flip over to TCPIP. I believe the command to turn it off is:

$ MULTINET CONFIGURE /SERVERS
SERVER-CONFIG> shutdown

This stops the master process. Alternatively, comment out the startup command procedure and reboot, which might not be a bad idea...gets rid of all the Multinet logicals etc.

Why the switch away from Multinet?

Thank you all, Multinet is no longer supported by Oracle.

Hello Gary,

http://www.process.com/tcpip/mndocs/MN%20v5.0%20Installation%20Administrator%20Guide/Ch09.htm#E55E56

has an overview of the various configuration files used by Multinet and what they contain (and how to access them). Obviously you do need to mirror this information in the new TCPIP setup. My advise would be to invoke tcpip$configure, start with the first menu and followup through all the submenus ;-). If you know IP in general and have an idea of your network this should not take more than about an hour at most (assuming a moderatly difficult network environment, if you do have 10 Ethernet interfaces in the box and do all kinds of "interesting" routing between the various networks it might take longer ;-)

Other things to consider are in-house developed applications that might use Multinet specific features, third party should be fine, they will use the UCX compatibility mode of Multinet anyhow.

As mentioned before, testing is your friend :-), especially make sure to test your environment under network load.

Greetings, Martin

P.S. Is 5.5 already out?

[Steven Lovjejoy]

Process Software is fully committed to supporting UCX emulation in our MultiNet product. Past versions of MultiNet were directly certified by Oracle, but currently are not - although we are working to rectify this. As a result, Process Software conducts its own 3rd party certification to ensure full UCX emulation in the MultiNet product.

We have many customers successfully using MultiNet with Oracle and will take very seriously any problems you might discover relating to UCX emulation and Oracle.

Steven, that is good to know, is MU4.3 certified under VMS 7.3-2?

[Geoff Bryant]

MultiNet works fine with VMS 7.3-2.

As to MultiNet v4.3, please be aware that we recently released MultiNet v5.0. Since we support the current version and one back (which is MultiNet 4.4), you should consider moving forward.
