Re: [U2] hpux to linux
Harold , If you're moving from Linux to Unix, I would check out Stratus computers. They're fault-tolerant Linux machines, running Redhat, with a long heritage from the 80's (with their own operating system). Their claim to fame is 99. % uptime or something ridiculously reliable like that...

Re: [U2] hpux to linux
I did a migration from SGI IRIX (RISC CPU) to RH AS 3 about 6 years ago. I've also done 2 other migrations from earlier to later versions of UV and the underlying OS just for hardware upgrades. The only differences with the OS change were: 1) As others have mentioned, I had to run fnuxi since I did an OS-level backup/restore. This was trivial, though. I just wrote a script that did the restore and executed fnuxi * in all the UV directories immediately afterward 2) I had to modify a number of shell scripts due to subtle changes in some of the OS-level command options. Most notably the echo command. There are other issues to consider that I always run into with any UV upgrade, regardless of platform. We have a number of customized VOC entries that differ from the installed versions and get wiped out by a UV upgrade. I have a file named VOC.MOD that I keep on the OS partition where copies of all the modified entries are stored. I copy that file onto the new platform and copy its entries into the UV VOC after the upgrade (and each test run). I keep similar files for any BPs and PROCs that need modification to work correctly on the new platform. It's typically utilities that end up in here. IBM changed the number of digits in spooler file IDs last time, for example, and it broke a number of our custom spooler utilities. It's hard for me to give a difficulty rating somewhere between easy and really hard. I guess I would say it's easy but time consuming. We have a different batch process for the first 3 weekends of each month as well as a month-end process. Testing each of those involves wiping out the UV data on the new server, restoring, and running the batch process (I change the SP.ASSIGN command so all the spooler files go to a dummy queue). When something breaks mid-way, I have to fix it and start all over. There's also a fairly long checklist of user applications that have to be tested. None of this is rocket science, but it does take quite a bit of time. I've done all the upgrades solo, and IIRC, it typically takes me a little over a month. Hope that helps. -John -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Oaks, Harold Sent: Tuesday, October 06, 2009 9:38 AM To: U2 Users List Subject: [U2] hpux to linux We have Rocket's Universe 10.2 over hpux 11.11 but are considering moving to a linux box.

Re: [U2] hpux to linux
My apologies. It should be ipcs in every case, not icps... KLP On Wed, October 7, 2009 11:37 pm, Karl Pearson wrote: One other gotcha from traditional Unix to Linux, for administrators, is the icps command, which didn't use to exist, and which took 2 commands to replicate on Linux. I used the ipcs -mop command to retrieve information about the shared memory segments being used. The command in Linux doesn't use those switches. Your mileage may vary. Does anyone know for sure?

Re: [U2] hpux to linux
1. Robert Gordon (robe...@genisyscorp.com) is an hp reseller who told me that a lot of his customers have left hp-ux for linux only to return to hp-ux later. He may have customers who are running UV. 2. I would ask Rocket. 3. I would put UniVerse on a different box and test it in SandBox mode. 4. I would be concerned about print jobs. 5. I would test every app in the SandBox before going live. 6. I would expect the install to take a half day and the testing to take a few weeks. --Bill Brutzman -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Oaks, Harold Sent: Tuesday, October 06, 2009 12:38 PM To: U2 Users List Subject: [U2] hpux to linux We have Rocket's Universe 10.2 over hpux 11.11 but are considering moving to a linux box.

Re: [U2] hpux to linux
Harold - I have done migrations from AIX to Linux and from Windows to Linux, and the nix to Linux migrations are quite easy. The biggest issue is that your backup method might need to be modified or rescripted to run correctly. Otherwise, moving from one nix server to another is mostly installing Universe properly. The application generally migrates easily with a uvbackup on the old system and a uvrestore on the new system (most easily done with UniAdmin tools). Why don't you setup a linux box on a 5 user UV development box and try the migration. Let me know if you run into problems.

Why don't you setup a linux box on a 5 user UV development box and try the migration. Let me know if you run into problems. The other point to watch out for is endianness. Basically, if you backup your AIX system using uvbackup, then use uvrestore on linux, everything should be hunky-dory. If you use global catalogs then you'll need to recatalog, and then everything should just run, famous last words ... If you copy your accounts using cp, or rsync, or whatever at the nix level, then you'll probably need fnuxi. I'm guessing you're talking linux on Intel (big-endian), while AIX is probably little-endian. So all the binary info in the datafiles will be the wrong way round, which is why you'll need fnuxi to fix it. Once you've done that, and again recatalog'd any global catalog stuff, again it should just work ... Admittedly I've been running all on Intel, but I've had no trouble copying accounts between SCO Unix, linux, and Windows. It works fine with minimal hassle as long as you are aware of the pitfalls.
