Swap size keeps dropping on Solaris 10 (x86)

Hi,
I have setup Solaris 10 (x86) on a SunFire V20Z, and mirrored my 2 hds.
raidctl c1t0d0 c1t1d0
recently i have been getting system messages that says
WARNING: /tmp: File system full, swap space limit exceeded
when i checked, I noticed that my swap size has dropped. I had setup c1t0d0s1 for swap (2GB).
When i reboot, the system will show the swap as correct, but it will start dropping over a period of time
bash-3.00# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c1t0d0s1 28,65 8 4193272 4193272
bash-3.00# swap -s
total: 565248k bytes allocated + 933124k reserved = 1498372k used, 2280600k available
The next day when i check again;
-bash-3.00$ swap -l
swapfile dev swaplo blocks free
/dev/dsk/c1t0d0s1 28,65 8 4193272 4193272
-bash-3.00$ swap -s
total: 1344296k bytes allocated + 1676016k reserved = 3020312k used, 642752k available
I have just rebooted my system again because my /tmp has dropped to 8.3MB
swap 8.3MB 4.0K 8.3MB 1% /tmp
My /tmp mount in vfstab shows;
swap - /tmp tmpfs - yes -
Any help?

Well, /tmp and swap are tightly connected to eachother, since its basicly the same thing.
Hence, when you allocate space in /tmp, the amount of available swap will drop, in the same way the amount of space available in /tmp will drop if a lot of swap has been allocated by processes running on the system.
swap -s will show you the amount of unallocated (or free) swap, that it shrinks over time is perfectly normal on most systems, however its not really normal that applications allocates that much swap on a short time.
I suspect that you have an application running on your system which is eating a lot of memory and hence using up your swap space, so next time this problem occour, i'ld run the following;
prstat -a -s size
This will give a list of processes running on the system, and sort them by how much virtual memory they have allocated.
Funny thing; i tested the command above on a S10 server, and found that nfsmapid had allocated about 400 mb. And i'm not even using NFSv4.. smells memory leak.
Hope this explaination is somewhat clear ;)

Knowing the Total Swap size in solaris

Dear all
can anyone help me finding out Total Swap size(constant) value in solaris 10
I tried swap -s and used (Used+available as TOTAL swap)
its keep changing, as its is a current swap size at that time.
actually My intention is to used this forumula in the script,as I found that solaris uses memory as physical+SWAP
(Physcial Memory +swap size)
Total physical+Total swap
what is the best way to find out Actual Total Swap size in solaris ??

I tried swap -s and used (Used+available as TOTAL swap)
its keep changing, as its is a current swap size at that time.
That's to be expected. See "How does Solaris Operating System calculate available swap? (Doc ID 1010585.1)"

If you want to know the size of the swap device, then look at the device(s) being used for swap and check the size of the slice or zvol. That'll tell you the starting value. The available will fluctuate with system usage. See Doc ID 1010585.1
What exactly are you trying to achieve with your script?

Attempting to install version 8 on solaris x86

The installation fails with:
ERROR exception while configuring command-line utilities
not enough space
The installation claims to require 236 megs. The disk has 2.3 gig free

So, how large is the swap partition? In my experience, default swap size values set by Solaris end-user configuration installation are usually good enough for end-user desktop system but not for developer's environment where you usually run some sort of server and/or IDE and it is usually good idea to increase default swap space values
Just as a reference value, I remember having similar issues installing Application Server 8 on a Solaris system with 560 MB swap space and 128 MB RAM and installation would go through only if /tmp was perfectly clean and system was running only bare bones processes. Since this is fresh Solaris installation, I would recommend reconfiguring the system with at least 1 GB of swap space - that would give you a nice margin if this system is to be used for J2EE development or production.

Solaris-x86 mount fat32 partition, the partition max size limit?

solaris10 x86, laptop, 10G FAT32 partition for windows & x86 exchange data.
the fat32 partition mount as normal, can be read fine.
but write some file by x86, that can not find by windows.
anyboy know did the solaris-x86 mount fat32 partition, the partition max size limit? or no limit, why this problem occur?

Mounting Windows partition in Solaris
The easiest way to share data now is to do it through a FAT32 partition. Solaris
recognises it as partition of type pcfs. It is specified as device:drive where drive is
either the DOS logical drive letter (c through z) or a drive number (1 through 24).
Drive letter c is equivalent to drive number 1 and represents the Primary DOS partition
on the disk; drive letters d through z are equivalent to drive numbers 2 through 24,
and represent DOS drives within the Extended DOS partition.Syntax is
mount -F pcfs device:drive /directroy-name
where directory name specifies the location where the file system is mounted.
To mount the first logical drive (d:) in the Extended DOS partition from an IDE hard
disk in the directory /d use
mount -F pcfs /dev/dsk/c0d0p0:d /d
You can use mount directory-name after appending following line is in
/etc/vfstab file
device:drive directory-name pcfs no rw
for example
c0d0s0:c /c pcfs no rw
If your windows partition like the following means
C: - NTFS, D:-FAT32, E:-NTFS, F:-FAT32
Then you can only mount D, F not C & E.
Mounting D Drive:
mount -F pcfs /dev/disk/c0d0p0:c /mountpoint
Mounting F Drive
mount -F pcfs /dev/disk/c0d0p0:d /mountpoint
The driveletter only for fat not including other file systems (ntfs or any linux filesystems).

At first I would have said that the total SWAP size is 6,6GB, but now I am in doubt since I see several SWAP line on the df OUTPUT.
Please help:
1. What is the total SWAP size for the machine?
2. Why is there 4 lines mentionning SWAP on the df OUTPUT?
3. With 8GB of RAM on this machine do I need to increase the SWAP?
4. If yes how to increase the SWAP?
Thanks in advance !

Swap can be a confusing thing. It's an overloaded term that people often use to mean somewhat different things.
1. Determine the swap allocated for the system with swap -l. The number of blocks minus the swaplo value will give you the true count. Blocks are 512 bytes, so do the math to get a GB value.
2. df output reflects file systems that are currently in use. In Solaris 10 there are a few virtual file systems that are backed by swap space itself. You'll notice all these swap fs components have the same size because they use the swap as a common pool.
3. Sizing swap shouldn't be based strictly on the amount of physical memory available. While there are guidelines for doing precisely that, those guidelines are given for the general case (i.e., no information on the apps that will be running). Monitoring demand is key. swap -s and vmstat will both give you a good general view of the demand for swap.
But, if you're a guidelines sort of person:
http://docs.sun.com/app/docs/doc/817-5093/fsswap-31050?a=view
4. The easiest way to increase swap is to make files that can be added to the overall swap space. I generally prefer this approach from the ground up, because it means I never have to dedicate disk space to a swap region. There are different steps for doing it with UFS and ZFS. Here's the ufs way:
a) Pick a UFS file system with space on a disk that isn't hot. Make a swap file and add it to the swap space like so:
- # mkfile 1024m /filesys2/swapfile
- # swap -a /filesys2/swapfile
Then check the outcome with swap -l and swap -s.
In many cases I will add a swap file to a customer's system and remove the partition-based swap (swap -d) that they have. There is no appreciable difference in performance and the flexibility of moving swap can come in handy when a system has to accept a different workload with a minimum of downtime.

Why swap size error when I install ides ecc6.0 in windows 2003 x86

Hi,
   I feel very confusion why the installation prompts me that "Swap size are not meeting condition" when I install IDES 6.0 in windows 2003 server x86.
   The ides type: ECC 6.0, MS SQL server 2005, Windows 2003 server x86.
   It's windows, not linux, where is the swap space?
   Could somebody give me a kindly help?
   Thank and thank

Hi,
In Windows, Paging File Space (Virtual Memory Space) concept is called as similar to Swap space thing in Linux/Unix OS. Both terms are used for virtual memory concept as per OS.
Minimum 20 GB of Paging File spaces is required for the SAP Installation on Windows. So ,allocate them from different drives or from single drive partition of your available Hard disk space.
Follow this path [to change your existing Virtual Memory or Page File size in Windows|http://technet.microsoft.com/en-us/library/cc737315%28WS.10%29.aspx].

Internet connection keeps dropping at night

I'm having a bit of a weird problem with my internet connection. I connect via an ethernet cable and the connection keeps dropping. It generally starts after 7pm and seems to be every 40 minutes. I have changed the microfilters and ethernet cable but I'm still getting this problem. The really weird thing is that all four lights on the hub are blue but the computer cannot connect to the router. Sometimes the connection will just drop other times it will say limited connection. I've finally had to resort to windows diagnostics and sometimes even that doesn't work. I swapped my black hub with the old white one and I didn't have this problem of the connection dropping but my connection speed dropped to 1.5 - 2mb.
I was thinking maybe there was something wrong with my ethernet card but now I think it must be something in the black hub because the white one worked. Am I correct in thinking I need a new router?

How to upgrade oracle 32 to 64 bit on sun solaris x86 64 bit OS?

Hi,
I want to upgrade/convert 32 bit Oracle Database 10.2.0.2 to 64 bit database. Existing 32 bit database is RAC and it is running on Sun Solaris X86 64 bit OS.
First, I want to know is it possible?
If yes, then what are the exact steps?

Hi,
Such a migration can be done, just follow the steps in Metalink note 62290.1
It is important to remember that 64-bit database requires more shared pool memory so you should increase your shared pool size.

Has Oracle ported Oracle8 for Solaris x86?

Hi,
usually I expect people to do a little research and I do not give everything chewed.
Point 4:
go to the
Oracle9i Database Migration Release 2 (9.2)
go to the chapter 3
Upgrading a Database to the New Oracle9i Release
go to the point:
Upgrade the Database Manually
Exactly from here:
http://download.oracle.com/docs/cd/B10501_01/server.920/a96530/upgrade.htm#1009200
Keep in mind
1) that the EXACT procedure you are following it is not indicated in this manual
2) you have to think a little ( do you have all the windows services created on the destination system? if not, you have to create them ... )
3) this procedure is not supported by SAP. It is a valid option but not supported by them. You have to practice until you get all the points correctly

Oracle Instant Client was a "feature" introduced with Oracle 10g. There is no 9i version.
Code that links with Oracle 9i libraries should be able to be linked with Instant Client 10gR2.
The resulting application will be able to connect to databases from Oracle 8.1 onwards.

Connect to Oracle database from Perl on Solaris x86

Hi,
How can I connect to Oracle database using Perl scripts on Solaris x86. It seems that DBD-Oracle Perl module requires Oracle client installed to work. Is there any Oracle client available for Solaris x86? Any one got a workaround? Thanks.
Angus Lee

Yes, you absolutely must have some portions of the rdbms installed before you can proceed. If your Solaris x86 machine is only a client, then you can get away with installing just ?/rdbms/mesg and ?/rdbms/lib.
I have Oracle 7.3.4, 8.0.5, 8.0.6, and 8.1.6 for Intel Solaris 2.6. I don't know if they'll run on Solaris 8 or 9 but I'm trying to upgrade at this very moment. As long as you conform to Oracle developer license, then you may download them from my machine.
I believe the reason Oracle dropped their Intel Solaris port is probably because Sun went through a period where they themselves dropped their Intel port. They've picked back up and if enough Oracle on Intel Solaris customers scream, then Oracle might pick it back up again too.
Send me an email if you're interested in the downloads.

ZFS Configuration Question - Also posted in Solaris x86

Hello,
I have 2 x 140GB (hw Raid-0 + spare). About 20GB is allocated to Solaris on UFS (standard installation and partitions/slices).
I would like to allocate the 120GB left on the disk drive to ZFS. That space is not unallocated to any file system for now.
I found a lot of documentation of how to create a ZFS Pool on an empty disk drive. The documentation is less clear on how to do it on a drive already use by another FS.
Any help will be appreciated.
Michel

Darren,
I just setup another Solaris x86 server tonight to play with. That future production server is in it's own vlan wtih no Internet access for now.
The test server has the same configuration, but less disk space.

DSL keeps dropping out - why? :(

I've had Inifinity 2 for a couple of months now and was very pleased with the service initially, high speeds and reliable connection. I work from home so the connection is very important to me.
The last couple of evenings the connection has been dropping completely and taking several minutes to come back up. It's not just the HomeHub, the fibre modem's DSL light goes off as if there's a line fault. This happens repeatedly throughout the evening, usually starting from about 5.45pm. There seems to be no rhyme or reason to it, it just drops. Nothing has changed here, it has literally started out of the blue. It doesn't matter which devices are connected - wired desktops, laptops, wireless phones/tablets/PS3. It just keeps dropping at random.
I even noticed it a few times this morning.
So, what do you lovely BT chaps need to know from me in order to sort this out?
Here are the router logs from this evening:

Thanks. I've now had 2 engineer visits so far and although they temporarily fixed the problem it has now happened again and is really starting to drive my hubby & I crazy!
The first time the engineer came out he checked the socket wiring in the house, found no problems, got a cherrypicker in to check the line at the pole (unsafe to climb apparently) and that improved the speed. He then checked at the modem and found that the cable the engineer (contracter?) who fitted it hadn't fitted the connector properly, some known issue with a fitting tool or something - so he sorted that out and woohoo, back up to full speed - 75mb+
That was fine for a couple of weeks.
Last Monday morning the connection dropped out. Then repeatedly dropped out every few minutes all afternoon, making it almost impossible to work. The speed had also dropped to 35mb according to various online checkers, including BT's speed test, which registered our speed as poor. I gave it until Tuesday just to see if it resolved itself/was a temp problem. No joy, still slow as you like - though no more drop outs. Contacted BT and an engineer came out the next afternoon.
Lovely chap, did all the same checks as before, no faults found, nothing wrong with the wiring. He even tried tugging on the phoneline to the house while checking the line, made no difference, so didn't seem to be anything wrong with the line to the house. All equipment indicated capable of full speed 80mb. All the engineer could say was that there was nothing wrong with the line, but clearly there had been something which caused the line to drop out and the cabinet then dropped our speed to stablise us. He requested a speed reset and all was well (ish) thereafter at about 60-65mb. Not quite as fast as the previous chap got it, but a darn sight better than 35mb.
The next morning another engineer turned up, unaware we'd had a visit the previous afternoon. I told him all about what the engineer had said the previous day and what had happened and he went away. Note I did tell him that he was welcome to come in and have another look, but there was nothing currently wrong for him to look at.
Last night (Sunday) the line dropped out a couple of times - again, no apparent reason. And once again we find our speeds capped at around 35mb. Doing the BT speed tests throws up odd results, telling us we have 0mb to the house and 38mb inside. Odd! I've been on to BT all morning, they tried to pass me onto a paid tech support line which I refused as both engineers have confirmed this isn't going to be something software/settings related - it happens regardless of which computer/laptop/device we are using wired or wireless, the line can even go down when we're not using it.
So, it's been logged on the last fault which is still open and being investigated. I have asked if they can please re-set the line speed for us but have been told this would only be a temporary fix. What else can I do? Something out there is making the line drop out and then we get speed capped. BT can't find a fault.
None the wiser as to why the connection sometimes drops out, but this is clearly the cause of the speed drops as the cabinet tries to stabilise things. We're only a stone's throw from the cabinet and both engineers say we should have full speed.
Could the modem be faulty and causing the drop outs? I don't know. I really don't know what else to do at this point. I guess we're going to end up with another engineer visit, but suspect all he can do is tell us the same thing and get the line reset.
Is there any chance our ancient BT wireless phone could be causing the problem? - we do get a bit of crackle on it, although the line itself is apparently clear of noise when tested. It's not connected to the same socket as the router, but to an extension downstairs (which was originally the master socket, but the engineer who fitted infinity swapped the sockets for us as we needed the fibre upstairs).
Anyone got any other thoughts as to what it could be? Has anyone else had this problem and resolved it?

Wireless keeps dropping out

The wireless was working fine, i had it working with network-manager i then was doing some work that i wanted to do via ethernet so switched the wireless off using the switch and now it keeps dropping out, i have had to remove network-manager as it wouldnt let me connect to wired for some reason, and have tried to get wireless re-working with wifi-menu, i have delected the config and created one using the examples and using netcfg and still having no luck. I looks as if the device is going into "power saving" and wont come out, outputs below:
