Just as the case for the use of "ALL-IN-1" for its printers, HP can use "VMS" for whatever it wants since it owns the company that owned that trademark. And since HP doesn't know about VMS as an operating system, its people probably didn't see any potential for conflict with some little known product HP inherited from Compaq. ------------------------------ Date: Fri, 2 Nov 2007 23:44:57 +0000 (UTC) From: m.kraemer@gsi.de (Michael Kraemer) Subject: Re: Good news: HP has retaken the VMS trademark !

But looking at the technology at bedside is an interesting diversion from the more serious thoughts of a very sick patient. Those Philips monitors have a gazilion connectors for all sorts of devices/sensors, and they even have the concept of a "hub" which allow you to connect even more sensors into the hub with just one connector going to the monitor.

My understanding is that > Agilent actually sold its medical products business to Philips not too > long after the spin-off from HP. I checked the Agilent site and they have a most interesting "history" page filled with the history of the "real" HP. http://www.agilent.com/about/companyinfo/history/index.html?cmpid=4491 And it confirms that in 2001, Agilent (which was spun off in 2000 (announced in 1999) sold the medical business to Philips. I hadn't heard of this. I had only heard that Philips was very happy with the growth of its medical business. So the fact that a nearby hospital went to Philips when they upgraded their old HP branded equipment is now explained. Is there any competition to Philips in that market ? And if there were ever a definition of "mission critical", it would apply to those life monitors. You really cannot afford to have errors or have them "BSOD" on an unconscious patient. Not sure what OS they run under the hood, but perhaps it would be VxWorks or Linux. Perhaps Mr Vaxman can take one apart during his stay in the hospital and rig it to play space invaders :-) I've had the misfortune of seeing one of those fully kitted out on a patient and it is pretty impressive all the stuff they can do (controling dosage of various fluids as well as monitoring everything, and in the ICU setting, it will transmit to every room any alarms for any one patient so if the doctor/nurse is in room 1 but room 3 has a heart attack, they immediatly know and can see the exact nature of the alarm from the room 1 monitor. (think of a smart OPCOM that knows which messages are important and should be prioritised over others). ------------------------------ Date: Fri, 02 Nov 2007 18:50:24 -0000 From: Hein RMS van den Heuvel Subject: Re: IO TIME vs COMputable.

What problem are you really trying to solve? I find it much more fruitful to find out what the IOs are and do something about it then to know how long they take.

(i think) It's not IO time, it is waiting time. Could be waiting for resources, events, synchronization, data, whatever. For batch jobs,(Disk) IO is often a large component, but a disproportionally large IO delay coudl come from a few, slow, network IOs. Maybe the batch job triggers heavy Oracle queries? You correctly identify the scheduling state COM but not CUR as looking like IO time. But there is also waiting for implicit (RMS bucket / XQP ) Locks around IOs.. Furthermore, IF you batch jobs go COM, then the system is overloaded already. If you are thinking of speeding up the IO, then the same job is likely to simply spend more time in COM state versus LEF state. On the other hand, if you could avoid doing the IO, it is a win-win for all involved. That could be as simple as pre-extending output file and using larger buffers. > how can i find the reel "IO TIME" ou COMputable TIME for the batch process. There is no fool proof way that I can quickly think of. If you are very curious, and have nothing better to do, then you could consider sampling the process states for a while, maybe 10 times per second and just count CUR, COM, LEF and HIBER to get a distribution picture. Also note that some of the COM/CUR time can be hiding active IOs, notably when work with RMS options like Deferred Write, Write-Behind and Read-Ahead. And also note that some (most READ) IOs could easily be resolve from cache while the process is CUR. > or i am wrong in my reasoning ?

IO time DOES NOT equal the difference between CPU time and Elapsed time. There are many reasons why this is so, including: - job being COMputable but not active (partially noted in the orginal post) - buffered IO on sequential files (which proceeds asynchronously while the job is executing) - the effects of the disk caches I agree with Hein, the numbers are a guide (and there are many more than just the ratio between CPU and Elapsed time). The overall system performance is the goal. There are many things that can be tuned in the application, as I have noted in my presentations including the one on "Applications Tuning on OpenVMS" (the slides from which are admittedly among the back material that I have not yet posted to my site) - Bob Gezelter, http://www.rlgsc.com ------------------------------ Date: Fri, 02 Nov 2007 19:14:22 -0700 From: Scott Mickey Subject: minimum system requirements for OpenVMS 7.3 VAX Message-ID: <472BD97E.EC9308E0@denver.net> Hello, Can a VAXserver 3400 with 12 MB memory and 150 MB disk install and run OpenVMS 7.3? I'd like to purchase the OpenVMS 7.3 Hobbyist CDROM, unless 12 MB memory and 150 MB disk isn't enough for this OS.

This VAX has no SCSI interface, so I think a network boot is the only option. Currently, it boots diskless using NetBSD. NetBSD does not have a DSSI driver (as far as I know), so I cannot use NetBSD to write to the disk (dd copy a NFS mounted OpenVMS CDROM to the 150 MB disk). Is it possible to load an OpenVMS kernel via the network (same as NetBSD does), and run the VAX diskless with NFS support? -From what I've read, I don't think so. Another possibility: This machine does have a TK70 DLT (CompacTape-II) tape drive. NetBSD has a driver for the TK70. Could I boot NetBSD, NFS mount the OpenVMS CDROM, and write a OpenVMS bootable image to tape? Then, boot from the tape and install OpenVMS on the DSSI disk? One last question (just curious): I know Oracle DB was originally deployed on VAX/VMS. What was the approx minimum memory required for Oracle versions 5 or 6 on VAX/VMS, in the late 1980's? Today, running 64-bit Oracle on machines with tens or hundreds of GB of memory, I am curious to know what it was like to run Oracle at the other end of the spectrum, with just tens of MB available.

Probably, but barely. Space will be tight in both categories.

Depending on what you want to do, a VMS version older than V7.3 might be a better idea for a system with so little memory and so little disk space. I'd avoid anything older than V5.5-2, unless you're a serious antique lover with minimal desire to run any real software. > This HP web page says OpenVMS 7.3 can be downloaded for free: > http://h71000.www7.hp.com/openvms/license_software_programs/index.html > Is this true?

The hobbyist CD-ROM is a pretty good bargain at $30, but if you can borrow a kit from someone, or if someone will let you download a kit, you may be able to save some of that $30. HP does not have a free, well-publicized, publicly accessible download server for this stuff. > If the VAXserver 3400 can run OpenVMS 7.3, then the next issue is > how to get the OS from the distribution CDROM onto the DSSI disk. > This VAX has no SCSI interface, Unfortunate, from the hard disk and CD-ROM points of view. > so I think a network boot is the only > option.

It's possible to install VMS from TK50 tape, which was a standard software distribution medium at one time (long ago). TK70, too, I assume, but TK50 was the usual TK medium for this purpose. Getting a TK50 (or TK70) kit will probably require help from someone who has comparably old VMS junk which has a CD-ROM and a TKx0 drive (and some considerable time to kill -- TK50's are pretty slow). The VMS distribution tapes are normally made on a VMS system, and more is involved than just copying stuff from the CD-ROM to the tape(s), so I'd expect it to be a challenge to make the tape(s) from a non-VMS system. I seem to have some command procedures lying around ("28-JAN-2003") which I probably used to make a two-TK50 tape set back then. If you get desperate enough, send me some e-mail, and I'll see if I can still make it all work with the current junk collection. A nearly free VAXstation 3100 model with its built-in SCSI would probably make a better toy system, if you really want to do anything with it. (An Alpha would probably be even better.) But I assume that this system fell onto you, and you're trying to work with what you have. ------------------------------------------------------------------------ Steven M.

Both adjust the size of the buffer allocated against the particular socket data transfer direction (send or receive). The SYSCONFIG mechanism you relate does it on a system-wide basis while the setsockopt(SO_SNDBUF)/QIO-SETMODE(TCPIP$C_SNDBUF) performs it programmatically on a per-socket basis. This post continues a thread where I observed and queried why were (at least the reported, later versions of) TCP/IP Services default values so much larger (and by default providing greater throughput) than for MultiNet.

I guess building a "standalone environment" on such a pen drive would be worth being "officially supported" -- kind of a "last resort".
