[U2] Re: U2 Users Digest V1 #2326
Charles-
As I read it, the unhandled exception is happening within the U2 object
when you are trying to execute the Java method PbrGetMgrList.
I never heard of JavaBridge before, but after reading the requirements
at http://php-java-bridge.sourceforge.net/doc/overview.php, I don't
think that is the source of the problem (java.inc is a PHP include file,
and might be referenced through a URL such as
|once("http://localhost:9090/JavaBridge/java/Java.inc";);|). You can
verify that the JavaBridge is working by calling a Java method outside
of the U2 object prior to calling the PbrGetMgrList method; if it works,
then something is happening to your U2 object. I don't have enough to
troubleshoot any further at this point.

Re: [U2] How to setup Distributed files across the network
You need UV/Net. There are two solutions. 1. Wherever you want to run the application, set up VOC entries to point to the remote part files, using hostname!pathname syntax in the DATA.FILE (field #2) entry. This will be picked up by UV/Net software and afford remote access to the part files. Then build a (local) Distributed File based on the part file records in VOC as usual. 2. Set up remote accounts in UV.ACCOUNT, again using the hostname!pathname syntax. Wherever you want to run the application, set up regular Q-pointers to the files in the remote accounts. Then build a (local) Distributed File based on the part file records in VOC as usual. --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

If you're talking about unix or linux, you can access remote UV files via NFS. Just set the ALLOWNFS flag in the uvconfig file to "1" and run uvregen. If you're talking about Windows, I think you can use CIFS (I'm not sure if there's a corresponding uvconfig flag). Since this is at the OS level, no special UV software is required. This might make sense in a disaster recovery scenario where you're storing the data on a high performance and highly redundant SAN (they typically support NFS and CIFS nowadays), and plan to have a backup OS machine either as a physical duplicate or a virtualized copy on alternate hardware. If the OS hardware fails or the OS software gets hosed by a buggy patch, admin error, etc., you just switch to the alternate OS machine and there's no need to restore your UV data. If they just want to split the application and data onto two standard servers, I can think of a few non-trivial problems. For one thing, application performance may be impacted, possibly severely. For example, NFS would need to be configured on the server end to do all I/O synchronously (not the default) to avoid file corruption during a crash. This slows things down since the client (which is the OS server in this case) has to wait for an acknowledgement of each write to traverse the network. Another major problem I see is that the potential for downtime has now more than doubled. If machine A is down, you're down. If machine B is down, you're down. If the network connection between A and B is down, you're down. As far as benefits, maybe there's something I haven't thought of, but I can't think of any off the top of my head. -John --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
[U2] How to setup Distributed files across the network
Can someone tell me what is required to setup and use distributed files over a network. My client want's to separate the Application from the Data, so that each is on a separate server. I'm sure someone has already done this or something similiar before and I would appreciate any insight you could share on how to set this up, what if any, additional Universe modules are required. Any feedback would greatly be appreciated. Thanks for all the help to date.

RE: [U2] Universe Windows reading a Virtual Tape File
Ron: I was able to restore a D3 account (from Linux) onto a UniVerse on Windows machine (my Thinkpad). In order to accomplish this you need to know the secret IBM/U2 handshake. Fortunately, a VAR told me what that secret handshake was and I got it done. I emailed Curt the instructions for this secret handshake so he should be able to properly restore a D3 account onto his UniVerse on Windows machine. Colin Alfke told me how to do the same thing with UniData and I was able to upgrade our clients from D3 to UniData by doing an account restore.

RE: [U2] Universe Windows reading a Virtual Tape File
UV on windows does not do virtual tapes but if you do a T-DUMP from D3 you can load the file(s) to UniVerse using the T.LOAD verb with the PICK.FORMAT option. I have both D3/Windows and UniVerse/Windows and have had good success moving small numbers of files.

Re: [U2] Universe Windows reading a Virtual Tape File
Not a dumb question. I've seen threads on here before about this. I think the bottom line is that universe on windows has no way to deal with virtual tape, but universe on unix/linux does. So if you have access to universe on unix, load your t-dumps there and then use uvbackup to save/restore to the windows machine. I might be wrong, but I seem to recall that universe can import a d3 file-save, and maybe the program that does that can read from a file. As another alternative, If what you have is t-dumps, the t-dump format is almost trivially simple. You could write a basic program using OPENSEQ/READBLK to read from the virtual tape file and load the data--your own t-load program. Has anyone ever seen a virtual tape driver for windows? In the same way that you can create a virtual disk in ram, has anyone ever seen a program that creates a virtual tape from a disk file?

Re: [U2] Universe Windows reading a Virtual Tape File
Curt, The only "virtual" save and restore processes on Universe are uvbackup and uvrestore, and they work only with eachother and only with existing Universe accounts. We have two tools that you can use, however, to accomplish your goal. Please let me know if you would like to discuss these. And remember, there are no dumb questions.
