Re: [U2] REPLICATING DATA
There's a similar product called Syncrify. Worth a look. Re dynamic files - remember that copying dynamic files is ONLY acceptable if the files have been closed and sync to disk. On your old version of UniVerse IIRC a DB Pause/resume does not sync the dynamic file headers as it does on current versions. I would check that with Rocket before you look at doing a dbpause/resume. Dynamic files rely on current modulus, split and load information held in shared memory. That information is only written back when the file is closed. So you can copy the file over, but if that information is out of date the file will not be usable and will eventually corrupt.

Try installing Cygwin and then rsync under that. I've had good success in the past with a basic (non-gui) cygwin install on a windows machine for other projects and rsync certainly works well in that environment. You can also set it up with pub/priv key auth for non-interactive operation too. I think the more recent releases of rsync will allow you to pull or push data in non daemon mode. At least that's how I use it to backup my daily work from my centos workstation (no rsync daemon running) to my crunch-bang (debian) laptop. The laptop runs the rsync out of cron. The script detects which wireless network it's on so doesn't run when at home. Setting some flags in the file system from UV and visa-versa would give you a reasonably good integration with dbpause etc etc. Cheers Peter Peter Cheney Universe Engineer t 07 3017 8837 | f 07 3002 8400 e peter.che...@firstmac.com.au | w www.firstmac.com.au From: u2-users-boun...@listserver.u2ug.org [u2-users-boun...@listserver.u2ug.org] on behalf of Anthonys Lists [antli...@youngman.org.uk] Sent: Thursday, 5 September 2013 8:55 AM To: u2-users@listserver.u2ug.org Subject: Re: [U2] REPLICATING DATA On 04/09/2013 20:27, Ard956 wrote: We are on Windows Server 2003.

Re: [U2] REPLICATING DATA
Dynamic files increase the risk that using third-party technology (rather than U2 Replication) will result in corrupt files on fail-over. This is because dynamic files increase the probability that a single logical write will result in multiple disk writes - 3rd party technology will not know the correct write boundaries.

Specifically, it's not safe to have overflow in hashed files because the overflow pointer and overflow data require two separate writes to disk. If a failover occurs when only one of the two writes has been completed, you'll likely end up with a corrupted file. I've eliminated this issue in our environment by keeping all hashed files sized to have no overflow and only using dynamic files for temporary report data.

Re: [U2] REPLICATING DATA
Hi Andrea: U2logic does replication via UniObjects for Java. It is built-in to our U2WebLink middle-ware engine. You just need to surround you writes and deletes with a few lines of code and our software takes care of the rest. This software works for version 10.1 of Universe and above. You can contact me off-line for more information.

Re: [U2] REPLICATING DATA
Back in 2000 at a previous employer my then boss and I implemented our DR plan on UV9.something using a nightly rsync. It wasn't a hot DR site but that didn't matter and we were also able to shut down UV for the duration of the backup which was from the live disks to backup disks using the Solaris dump/restore and once complete we'd dump the backup file systems off to tape and then rsync it to DR. The backup scripts were mostly perl but the rsync was ksh scripts. Only took a few months to hack together. The disks themselves were all under Veritas VM control.

Hi Andrea, Rocket Professional Services can help you out with that, as well as give you the pros/cons of the different approaches - since other methods will increase the risk that your replicated copy will have corrupt files or be out-of-sync with production.

Dunno what the Windows equivalent of rsync is, but if you're backing up across machines, rsync tries to not copy stuff that hasn't changed.

Re: [U2] REPLICATING DATA
Yes, a power outage would be one cause, but any hardware failure of the active cluster node that causes the other to assume the active role will suffice. Best practice is to literally force a power outage on the failed node when this happens via a STONITH device (acronym for shoot the other node in the head). Each of our servers has its power routed through one of these devices with a serial port connected to the other server. Without STONITH devices, you run the risk of a split brain situation if the two servers lose contact with each other for any reason. The backup node assumes the active role when it doesn't receive regular heartbeats from the active node, but if this is simply due to a network issue between the nodes, the original active node may still be serving clients. Now you have two active nodes serving different clients from their own individual copies of the data. I've experienced that situation once, and I hope to never go through it again. -John -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Wjhonson Sent: Tuesday, September 03, 2013 4:32 PM To: u2-users@listserver.u2ug.org Subject: Re: [U2] REPLICATING DATA Under what scenario would the overflow record not get written?
