I have a vague recollection that I've seen something in the Unidata manuals - years ago - documenting the maximums for a TCL statement, record size, number of IDs that can be specified in a SELECT statement, that sort of thing. I've searched the manual set but I can't seem to locate that information. Anyone recall offhand where these are documented? -Kevin http://www.PrecisOnline.com --- 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/
[U2] RE: UniObjects connection timeouts?
What version of the UniObjects assembly are you using.. We ran into this alot with the first .Net assemblies IBM shipped, but later releases are a lot better, and the RPC issue seems to have been largely resolved. FYI - We use the same assembly on Unidata and UniVerse, and had the same/similar issues on both U2 Products - moving to a later release of the assembly solved a lot of problems on both U2 products..

UV 10.2.3 on Windows 2003 server. UniObjects calls in Windows Forms (.Net 2.0) using VB.Net. UniObjects are supposed to have a default no-time-out. I am not modifying any properties or parameters, and per UniObjects developers doc: Timeout This property specifies the length of the timeout for a connected session. The timeout period is used by the UniVerse remote procedure call utility (UniRPC). The default value of this property is 0 (no timeout period). For values greater than 0, you must specify seconds. Session Object: Properties 3-52 C:\Program Files\Adobe\FrameMaker7.0\UniVerse Note: If you enter a value that is too small, a running process (for example, the Read method) may time out. If this occurs, an error code is returned and the connection to the server is dropped. This applies to both session and read timeouts. Again, I am not changing these properties at all. Yet, sessions unattended for more than an (unknown) amount of time, about 4 hours at the latest incident (but I hit it with less time earlier, somewhere around 1 hour), are causing the following exceptions to be caught: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.[IBM U2][UODOTNET-UNIRPC][ErrorCode=81009] The RPC failed. Note that message 81009 does not exist in SYS.MESSAGE. Does anyone know how to make the sessions truly NOT time out, or fix whatever this problem is about?? Thanks in advance!

[U2] Hash / File Types in Unidata
Can anyone provide me with a link / info on the differences between Hash/ file types 0 and 1.. I would like to know more about how these work internally, so that at design / file creation time, the files can be created with the correct intended type, rather than just relying on file stats to check group allocation, and then switching file types if the allocation is sub-optimal.

RE: [U2] Inter-Process Control...
If this is the approach you go for, I would recommend that you use a resource lock, rather than a record lock (no need to open file etc etc)... Resource locks are set system wide, so are not limited to a single account / file / record, and are accessed with the LOCK/UNLOCK UniBasic commands... You have 64 locks to use as you see fit.. In my mind the solution depends on how quickly you need the second process to wake up.. if a 30sec+ delay is ok, then using a resource lock could be an option with a SLEEP 30 on the locked condition.. Otherwise I would be looking at launching the child job as required, rather than having it wait for work..

We have two phantom processes. The first phantom needs to wait for an event to occur with the second phantom. I realize that I could have the first phantom loop, check, then sleep. However, I'd like to avoid wasting resources. Back on the Prime, I could use semaphores, to control this flow and this was clean, and simple. Has anyone come across a means of having a phantom wait on something, so it only wakes up when it needs to perform its function? To try to explain better: Phantom1: Loop Wait on semaphore Perform a shared process (batch updates would be an example) Repeat Phantom2 (3, 4, ...): Loop Process records Notify semaphore Repeat Thanks, Tom Whitmore RATEX Business Solutions --- 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/ --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] [UD] Trigger (singular)
Hi Bill, What you have is the simplest form of the wrapper. I had to create a 'generic' wrapper so I had to add logic to deal with the possible return values of execstat and the possibly amended record. As the wrapper is making the multiple calls it now has the responsibility of quitting at the appropriate time and maintaining the record value between subroutine calls. I'm on leave today, but I will post the 2 wrappers I have for update and delete as soon as I get a chance.
