RE: [U2] Developers permissions with Windows and UniData
Bill; You may be able to take ownership of the source code directory by another user and then remove the administrators group write access to the directory. I've seen UD do some funny stuff with the SQL permissions (if a member of the administrators group is the owner of the file then any member of the administrators group has full access - regardless of the permissions defined), so you may have to do some wrangling around to give a non-adminstative user ownership of the files. A user requires write access to the VOC on the account they login to (although there is a way around that). I think as long as you remove their rights from the source code directory (and dictionary) and not the entire account everything should work OK. In the AdminNT.pdf of the doc there is a table with the required permissions that the various types of users require. Actually, a user can stopudt their own processes - but you do need to be an administrator to use deleteuser. I've used stopudt on telnet processes, other processes may have different owners. Task Manager may show the user information (or maybe something more involved like Process explorer). hth Colin Alfke Calgary, Canada > From: wphaskett > > We have a network with several Windows development machines on it.

RE: [U2] Does anybody have a hot backup server?
I'd be worried about a particular vulnerability in this scenario. If the system goes down while you are updating overflow or oversized data frames, you could get file corruption. A single U2 logical write can take multiple os writes, and at any given moment on a busy system, you probably will have this condition. You can minimize this risk by minimizing overflow, but it's probably impossible to eliminate it. Outside of uv replication, I don't think that there's a working solution to this "in-flight transaction" problem. With Unidata, RFS handles it nicely. --- We use LifeKeeper from Steeleye Technologies to replicate linux partitions at the OS level for UV redundancy. The servers are right next to each other and replication is done over 3 gigabit NICs - 1 for each of 2 partitions, and an extra for redundancy. There are crossover cat5 cables running directly between the NICs. The users connect to a virtual IP address that points to a 4th NIC on whichever node is currently active. In the event of a failover, LifeKeeper handles moving the virtual IP address, mounting the filesystems, and the startup of applications. We have yet to experience a failover on the current hardware, but I found during pre-installation testing that UV was running on the backup box within a minute or so of failing over. YMMV. LifeKeeper allows an application dependency hierarchy to be created so you can define the order in which applications start. In our case, UV depends on access to Active Directory (samba/winbind) as well as having the underlying filesystem mounted. LifeKeeper is built on top of linux software RAID, so /proc/mdstat on the active node has the following contents: Personalities : [raid1] md1 : active raid1 nbd9[1](W) sdb2[0] 24065370 blocks super non-persistent [2/2] [UU] bitmap: 2/184 pages [8KB], 64KB chunk, file: /opt/LifeKeeper/bitmap_ntdata md0 : active raid1 nbd1[1](W) sdb1[0] 80381196 blocks super non-persistent [2/2] [UU] bitmap: 28/614 pages [112KB], 64KB chunk, file: /opt/LifeKeeper/bitmap_uvdata while the backup node shows no mounted RAID filesystems. If the primary were to crash, the backup server would mount its local copy of the filesystems and the primary server's replicated filesystems would be marked as dirty. The primary would have its unmounted filesystems synced to the backup when it came back online. As others have pointed out, if you have a cold-spare scenario like this, there is no add'l licensing charge from IBM. You do have to obtain a 2nd license in order to install UV on the 2nd server, but you won't be charged. -John --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/ --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

RE: [U2] Does anybody have a hot backup server?
Hi, Under Universe/Linux we use Data Replication Block Device. www.drbd.com (open source linux product) A low level software called between logical partition and hdd partition. Cluster over LAN. We define it on partitions where Universe db is installed (including universe himself). On the hot-standby server, the same partition is created and not mounted (universe is not started ~ for this raison, we don't need IBM's license) On fail-over, we switch the ip adress to the hot-standby server, we mount the partition, we boot uv and users can work ... 2 minutes. One restriction, we don't use DYNAMIC files because the headers are not permanently flushed when write occurs files. Coupled with Universe Transaction Logger set on strategic files to ensure "record update integrity". My two pence.

RE: [U2] Does anybody have a hot backup server?
There are quite a few ways to get there, depending on facilities. 1) If you have fiber connecting the sites, then simply mirror the drives, or, if using an array, mirror two arrays using built-in operating system functions. 2) You can do mirroring at the volume level using a number of third party products, such as Veritas Volume Replicator. 3) You can use rsync with a cron job. It is really efficient as it only sends deltas. 4) You can use the IBM U2 publish/subscribe facilities. 5) We have been implementing hot backup servers using the DBMS (Prime INFORMATION, PI/open, and UniVerse) using triggers to perform asynchronous updates for about 20 years now, keeping the data up to date within a few seconds. It was really efficient in PI/open, but requires a lot of horsepower in UniVerse due to the trigger implementation in UniVerse. Regarding options 4 and 5, I don't recall the particulars of the licensing, but in theory you could have a two user U2 license on the backup site, and switch to a cold backup of the primary license on the backup system if you ever need to use it. From what I remember, cold backup licenses are not chargeable. I'd have a conversation with IBM about it. Best regards, Henry Henry P.

RE: [U2] Does anybody have a hot backup server?
If you have a cold backup server I believe it is free, but you do need to get another license and sign an agreement. What we do is, we have Universe installed and licensed on the DR machine but not running. We use rsync to copy the data files from production to dr on a regular cycle. When production goes down we start up the DR machine and carry on. Of course this solution is not completely failsafe, as the application does not use transactions so it is possible that partial transactions may be committed to dr depending on timing etc, so it may not suit everyone, but it is enough for our needs.

RE: [U2] Does anybody have a hot backup server?
Since we write software for 911 systems it is critical for our application to be able to be switched from one system to another. We use Unidata and have written a subroutine that gets called for every write and delete it creates transactions that are sequential and all of our 1000 programs call the same routine. We then use NFA to access the backup system and we have a phantom process that reads each transaction from the primary and writes it to the backup we also use secondary NIC cards to ensure speed. This works very well and the backup is always within a couple of seconds of the primary. (we also do this with 3 and 4 systems together). Anyway you can stop the phantom and do maintenance on the backup then restart the phantom and all the transactions catch up. The only down side is that you have to log out and back on. We have separate icons so end users can either be on the primary or backup and we also have flags set so someone doesn't log into the backup by mistake. Unidata also has data replication which I hear good things about but we have never taken the time to try to decide if it would be worth it to switch to it. Any interfaces that you might have that are serial we connect to a network terminal server and all we have to do is stop and start the interfaces from the backup and everything works.

RE: [U2] Does anybody have a hot backup server?
I guess it would depend on the size of the database. If you had your drives mirrored, and every two hours, broke the mirror, and created a differential backup of of the mirror on another system (ex. rdiff-backup). This would create a duplicate system based on the mirror, as long as your drives could update the mirror quick enough when reconnected within the two hours before it will be broken again. rdiff-backup will work locally on a LAN, or through the internet to create an offsite duplicate server for disaster protection.

RE: [U2] Does anybody have a hot backup server?
We have our two production servers in a cluster sharing the same disk array. The disks are in a 3-way mirror so if we experience a hard drive failure, the system should remain up. Either system in the cluster can access the disk array - but of course, only one system can control it at a time. Each system in the cluster has its own OS and we copy certain data from the active server to the passive server each night - data such as logins, passwords, certain files under /etc, and because we have Universe certain files under our UV home directory. The nightly copy process keeps all the OS related data in sync. Remember, all our database files are on the disk array which is always available to both systems - so no nightly or hourly backing up of that data is needed. Every first of the month we switch between the systems. This does two things for us. First, it makes sure the passive system is still working and is ready to go in case of a failure. Second, it makes sure we're copying all the necessary OS level files as needed - which we discovered after a few times that we forgot a few UNIX level files. For networking purposes we had to create new IP address that always point to whichever system is active in the cluster. Then we had to push that IP out to all our users. So there was some setup pain, but once everyone and every device was pointing to the new IP address, we haven't had any problems. There were some pretty big costs also - we had to purchase additional Universe licenses for the "backup" system - we got them at a reduced cost, but still, it seems silly to have to pay for licenses that will always be offline. We also had the same issue with every other software license we have on the active server - but I believe we were able to get them all at a cheaper rate.

If it is Unix, consider using cron to copy data from A to B every hour or so. I talked with IBM a while back on this. My recollection is that IBM said we would have to buy UV user licenses for both machines. We had some additional big $ license issues here so for us, that issue went away.

ASP.NET itself is browser/device independent - when the browser connects to the server, the appropriate code/controls are returned for the specific client. The tables that determine the code that gets pushed out are open for anyone to maintain, though I know of very few instances where this required, desirable, or even discussed. Further, .NET is not limited to ASP.NET. Therefore, as I said, you can use it as the communications pipe from Adobe Flex, PHP and other completely non-.NET clients. I'm sorry to turn people's notions of .NET upside down, but someone has to because obviously Microsoft hasn't done a great job of explaining .NET to a large number of people who still believe many of the myths. As just a couple examples: - I read recently a statement that .NET is expensive. That's not correct - it's completely free for development and use. - People tell me they don't use web services because they don't like IIS. .NET web services are not dependent on IIS or any other web server. > 2.

IBM WebSphere has a lot of advantages in > this space. That's sort of apples and oranges too. Yes, WCF has scalability issues and I won't argue for or against it. But as a minimal definition, WCF is a free component of the .NET Framework which can allows inter-process communications with a few lines of code, and WebSphere is a large commercial offering with a large set of implementation details. With reference back to my original statement a the top of this posting, we can't properly discuss solutions when there is so much mis-information in circulation. I don't care particularly whether someone likes or doesn't like .NET, Java, PHP, or the MV DBMS model. But when we assert whether some technology is good or bad, or right or wrong for some task, we really need to make sure it's for verifiable and context-specific reasons. You won't get a comment from me, for example if you say WCF is inappropriate for internet usage as an inter-process communications mechanism - that's what it was designed for, but your opinion and experience about how it does the job are your own. You will get a comment from me if you say cars aren't as good as unicycles because unicycles consume too much electricity. Yeah, I know, that makes no sense for many reasons because we all understand cars and unicycles and how they're intended for different purposes. When we're on the same page with .NET we can have the same discussions. When we're not on the same page about the facts, it doesn't matter what anyone says because pre-conceptions and mis-information preclude any point as being compelling in any direction.

Our cross-platform products that allow MV BASIC apps to be clients to other apps and the internet call to a service on a middle-tier windows box, that does the comms, and the results are returned back to BASIC. From the developer perspective it's all BASIC, and I don't need to work with shims, linked DLLs, or platform-specific utilities like CallHTTP. I'll use what's available when required of course, but I don't think I've written platform-specific code for about 4 years now and I'm quite happy with that. Thanks for the advice.

RE: [U2] validate active directory username & password from within unidata?
Hi, You can call DLLs from UniData on Windows with the CALLC function. It's in the "Developing UniBasic Applications" manual under "Linking Programs with UniData". I think there's a Universe equivalent, but as I don't use UV, I've never needed to check. This links dynamically, though - you only need to link a library into the executable if it's under Unix. This works with native code, but I don't know if it works with .Net DLLs. Adam This brings up a question: Does anyone know if we can link a C++ or .NET DLL into the UD or UV executables? Maybe call via a user exit or some other mechanism directly from BASIC? Shelling out is very inelegant, slow, and can be insecure.

RE: [U2] IDE
To add to this.. .Net also doesn't mean necessarily using web pages. If you're developing for intranet use, consider using windows forms with click-once deployment or sandbox mode. A lot of companies go the web page route because of the cost/hassle of deploying desktop apps and keeping them up to date, or the security concerns about installing software. They also equate web pages with stateless and windows forms with stateful. Neither of these is really revelant today. With ClickOnce deployment, the software is automatically published to a web server and installed from a web page. Subsequently it will automatically check for updates. No need to do a rollout: just give the user the installation link for the first time. With sandbox deployment it gets even easier. The software is downloaded automatically and run from the web page, but is not installed and cannot access any local system resources (e.g. file system) making it safe. I've used ClickOnce successfully, in particular for a site that was geographically dispersed and had frequent updates. It works well. OF course, now you also have Silverlight to add to the potential mix. So don't automatically think web when you think of .Net. The advantage of .Net is that you can use it for pretty much any sort of application once you have learned the language(s) and the framework.

RE: [U2] validate active directory username & password from within unidata?
> From: Bruce McAdoo > Any ideas how I might be able to validate active directory username & > password from within unidata? I'd encrypt the data in BASIC, pass it to a windows box, and execute an EXE that just does the authentication and returns a yes or no (also encrypted to deter corruption in the middle). This should be fairly straightforward. There are lots of code samples on the net for Active Directory. I recommend against shelling out with the user ID and password in plain text as this is very insecure. Everything can/should be wrapped in a BASIC subroutine to make the plumbing completely transparent to the application. This approach works for a wide range of these "how do I..." questions. This brings up a question: Does anyone know if we can link a C++ or .NET DLL into the UD or UV executables? Maybe call via a user exit or some other mechanism directly from BASIC? Shelling out is very inelegant, slow, and can be insecure. I have a blog coming out soon on this concept but haven't done this with U2.
