Hello netlanders, I have 20 Mb swap on the first disk and 10 Mb on the second. What did I have to do to tell 386/ix 2.20 to use the swap space on my second disk? Please reply via mail, if interest I summarize and post. -Axel -- fischer@utower.gopas.sub.org / fischer@db0tui6.BITNET / fischer@tmpmbx.UUCP Class of '93 That is not dead, which can eternal lie Yet with strange aeons, even death may die.

Hmm, looks like a real RTFM type of question. Let's see. I think we'll start at the permuted index... Lets look up the word "swap"... Hey, look at that - there's a swap(1M) command. Lets see what it says... .... -a Add the specified swap area.... .... -d Delete the specified swap area... .... -l List the status of all swap areas.... Looks like that is what you need. I know it sounds like I am flaming, but I'm not. I just think you should at least take a quick look in the permuted index before posting such a question to the net. I could understand you having a problem if it was listed under something like: diskmem(1M) - disk overflow memory allocator which looks like it has nothing to do with swap space (of course, it doesn't since it isn't a real command). -- Conor P.

You can start in the Bermuda index, but that takes a strong stomach; a lot of people get lost in those and are never heard from again. One of the strongest points in favor of the SCO version of UNIX is that they refrained from using psychological warfare and camouflage techniques when indexing their manuals. (Perhaps a UNIX first?) Has anyone ever made a utility which converts Bermuda indices into human readable form? Later, Andrew Mullhaupt

I don't think there is a better answer than a permuted index. Maybe you are really complaining about the one-line descriptions that are used to make up the index. Having a permuted index makes it real easy to look up what you are interested about. The case in point, someone had a question about "swap" space. By simply looking up the term swap in the index they would have found what they needed. >One of the strongest points in favor of the SCO version of UNIX is >that they refrained from using psychological warfare and camouflage >techniques when indexing their manuals. (Perhaps a UNIX first?) I don't know what they did to index the manuals, but I don't think it would be that much better. >Has anyone ever made a utility which converts Bermuda indices into >human readable form? You could try the TOC that normally precedes the permuted index if you can't figure out how to use the permuted index. -- Conor P.

Sorry for wasting netload. I was just to _lazy_ to look up in the Manual, `cause usually it takes quite a while to work with the ISC Manuals.

Speaking of swapping -- i have been experiencing some problems with adding swap areas (with the "swap -a" command) on my ESIX 5.3.2-C system (i experienced the same problems on my microport system as well). Sometime soon after adding a swap area on a second disk (either scsi or mfm), i get a panic message along the lines of "i/o error in swap" and the system crashes. I have seen this a number of times and have finally decided that it is better if i don't add a second swap area. The problem is that i have not seen anybody else complain or mention this; and i'm wondering if it is simply a problem with my hardware. Has anybody else seen this problem or am i the only one who attempted to add a second swap space?? derek -- Derek Terveer det@hawkmoon.MN.ORG

Sometime soon after adding a >swap area on a second disk (either scsi or mfm)... I too was having i/o error in swap problems (and panic) with AT&T sVr3.2u. I have 2 ESDI drives (different brand and capacity) on an Adaptec 2322 (no B, C or D, this one is over a year old). No panic when only swapping to disk0, regular panics when swapping on both disks. I reformatted disk1, made sure to have the correct bad-track entries, and formatted the drive vertically (it had been formatted horizontally but was being used vertically). Then I started beating on the system (with software) even harder than before, but panics are truly and honestly gone. I would suggest reformatting, running diagnostics and making sure you get the bad-track entries right. Paul. (debra@research.att.com)

I have had experience with second swapping areas under uport and isc. I don't presently have one active. With uport the first area (on drive 0) is hard-coded into the kernel, and you must leave it in place lest unix die: you can't delete it after adding the space on the second drive. I encountered a peculiar behavior: after hours or days, the listing produced by ps -ef would contain corrupted lines. I was able to provoke this by loading a large program, which presumably triggered the swapping algorithm. Presumably the kernel either clobbers its process table while using the second swap area, or gets into some sort of trouble with things that it stores there. This spooky experience led me to stick to drive 0 for microport swapping. I haven't exercised isc as thoroughly, but I did partition some swap space on drive 1. By now, though, extra memory is sufficiently cheaper and faster that I've left my swap area quite small (1 or 2 Meg) with 8 Mb of ram. This weekend, gnu emacs threw me an "out of memory" error. If it recurs maybe I'll activate that extra swap space. -- Norman Kohn | ...ddsw1!nvk Chicago, Il. | days/ans svc: (312) 650-6840 | eves: (312) 373-0564

If it recurs maybe I'll activate that extra swap space. I've been told by some folks that've done porting work for us that the swap space should be at least as large as your main memory. Otherwise, you get the "out of memory" errors.... This is most likely a problem on more active systems, with several users doing database or development work. By now, though, discs are sufficiently cheaper and faster that I always allocate at least 16MB of swap space, just to avoid problems. :-) -- Gary Heston { uunet!sci34hub!gary } System Mismanager SCI Technology, Inc.
