RE: [U2] Performance monitoring
Get a count of the number of read locks at a busy time. If it's more than RLTABSZ times GSEMNUM, you'll want to increase gsemnum. I would avoid increasing GLTABSZ and RLTABSZ by much; the lock table is a hashed table, and just like uv files, broad and shallow yields better performance/less contention. Also look at MFILES; in the uv account, do a PORT.STATUS with the MFILE.HIST option to see how things are going. Closing reopening files is very expensive. I've asked a few people if there's an upper limit, and while nobody will commit to an answer (feel free, anyone), there appears to be no penalty to making it too big. I don't recall what the scratch buffer pool does, and the documentation is sparse. SELBUF is interesting, if you're doing a lot of selects. The default is 4, in units of 1K. So, if you do a select, it starts accumulating a list of id's in RAM until the size of that list reaches 4K. At that point, it creates a file in UVTEMP, and you're going to disk. I can't see much reason not to increase this to 1024, so select lists up to 1Mb are created in RAM. These may help some, but unless MFILES is massively underconfigured and you're using some absurd amount of cpu to just close re-open files, I'm inclined to think that the symptoms you mention indicate that AIX VMM tuning will give you more bang for the buck. I'd be especially looking at how VMM is treating computational vs file cache; with the amount of data you churn through in a night, you'll want to be sure to heavily favor computational memory pages.

A quite different thing to check. From memory when we had AIX one of the batteries, I think for write cache, required replacement. The system would not cache any writes and performance slowed.

I don't think IBM ever corrected that because writing without explicitly locking is Bad Form. If I remember, when process A holds a lock on a record and then process B issues a write (w/o explicitly locking),by default B sits and waits for 20 minutes, then gives up with a write error. (In my opinion, the defaultlock.wait should either be forever, or a uvconfig parameter, not 20 minutes.)

How to proceed: - Monotor uv/errlog to see if you have write errors. - Look for programs that write without locking. - 20 minute wait limit is configurable. I set ours to one month (=2678400seconds), effectively forever, since we'd bring UV down up more frequently then that. To do so, execute a basic program from UV.LOGIN (that all uv processes execute on startup) that does ASSIGN 2678400 TO SYSTEM(1999).TCL command SET.SQL LOCK.WAIT 2678400 accomplishes the same.

RE: [U2] Performance monitoring
MFILES is related to the OS per process open file limit (documented in the uvconfig file). The specific name of this value varies for different OSes. It looks like the default limit for AIX is 2000 (listed as nofiles). This was the absolute maximum until around 4.3.1. An individual user can see their setting via the ulimit -a command. Some time ago we had a program that started getting slower over time. Turns out the original programmer had made liberal use of dynamic arrays rather than dimensioned arrays, and these become horribly inefficient when they become large.

RE: [U2] ODBC Connection to Universe on HP-UX [ad]
From: Henry.Martel We are thinking of changing our application connect to Universe through ODBC connections. Has anyone had experience doing this? Are there any performance issues or considerations that we need to be aware of? One of our clients was using ODBC with Universe and got into a situation where licenses would get consumed but couldn't be released. They worked closely with IBM for months and the only resolution was to buy more licenses to avoid other users from being inconvenienced. Yes, that's the way it worked out, so they needed to find another solution, and they called me. Nebula RD sells, support, and provides development services for mv.NET, which this site evaluated and then adopted as their solution. mv.NET allows for reads and writes, with familiar MV BASIC syntax, or optionally using SQL-like queries it seamlessly integrates with all facets of ADO.NET. We use it to move data between MV systems, to/from relational, and now between MV and Amazon SimpleDB and other cloud repositories. Email for more info.

[U2] [UD] Unexpected telnet/SSH error
This started out to be a bug report, but now I'm not sure if it's just a don't do that issue. Whenever I connect to my Unidata PE 7.2 over Windows via telnet, an unknown software exception error dialog would display on the _server_ desktop. I realized this was because I was telnetting onto the SSH port. OK, oops, don't do that. But I'd consider this a bug. Can someone else verify this behaviour and then report it to IBM through proper channels? (As a PE user I've never reported an issue directly to IBM and frankly wouldn't know how. Did I not RTM properly?) Thanks.

Re: [U2] ODBC Connection to Universe on HP-UX
Henry, The ODBC connection is the slowest connection into the U2 product line. If the application will not have a lot of users on it, ODBC will be fine. But, ODBC will not scale if you have numerous connections.

RE: [U2] [UD] Unexpected telnet/SSH error
Bill - the problem isn't that I want to run SSH or that I can't find telnet. Although I do have 7 MV DBMS platforms running on my system and none of them run on default ports. :) I did accidentally telnet to the wrong port, but then found the right port, oops, mea culpa. The issue is that it looks like anyone can generate a mysterious server desktop dialog simply by telnetting to the SSH port. That would have to annoy someone if it happens at the wrong time and you're not sure what caused it. Try it. If your default for Telnet is 23 and SSH is 22, just Telnet to port 22 and see what happens. T From: Bill Haskett G-Man: Is something listening on port 22?
