What is in swap
Is there a way to see which apps have been swapped?
Or maybe something more low-level if it's not possible.
Thanks!
I get strange results with it.
I just booted my PC (I turn it off over the night) and there's no swap being used, as top itself shows:
Mem: 319356k total, 278588k used, 40768k free, 13216k buffers
Swap: 497972k total, 0k used, 497972k free, 130092k cached
But then it shows that firefox is using 108m on the column swap:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND
3766 root 19 -1 72604 27m 4548 S 29.8 9.0 0:59.64 42m X

What is normal swap space utilization on Solaris 10
Hi all,
I'm running Oracle 11.2 on Solaris 10 on a couple of HP Proliant DL 360 servers.
Both servers have 72G of physical RAM with swap space set to 16G on both of them.
Server A has only one database and total memory free = 30G.

4 daemon 3204K 5912K 0.0% 0:00:00 0.0%We are using zfs file system on both servers (which is pretty much the standard these days on Solaris).
Recently I got an OEM alert that my swap space on server A had crossed the 95% threshhold on one of the servers.
But when I checked the server, I found that the average swap space utilization was 97.45.
In fact, what actually happened was my swap utilization momentarily dropped below 95% and then returned back to its normal range above 95% which caused the alert to be triggered.
So this made me wonder why my swap space utilization was so high on server A, or is this just normal for Solaris (v.10).
Checking with server B, I see that my swap utilization is only at 63.6% (even though server B has much more physical memory in use by the two databases than server A).
Main question is why is swap utilization so high on server A, which is configured the same as server B and with less physical memory actually in use.
Next question is should I be concerned.
When I check vmstat, I do not see any paging in or out or blocked processes.
See below for server A

Realize that SWAP is purely an OS facility; which is 100% external to Oracle.
The OS send little used or idle processes into SWAP when RAM is scarce resource.
The fact that SWAP is being used is not a Bad Thing, in and of itself.
as long as vmstat shows that BI+BO > SI+SO I would ignore the Chicken Little warnings. -

Iphone 4 randomly freezes - what hardware to swap
Good Afternoon, ive recently started up my own business fixing mobile phones - mostly cracked screens and chassis replacements.
Just recently i thought id got a bargain on ebay regarding an iphone 4.
It was described as working correctly, can make / receive calls and send texts etc but randomly locks up.
Ive got the phone today, unfortunately its locked to the 3 network so ive got a micro sim on the way so I cant actually proceed further at this point. Although it did crash once on me when i tried to select language's etc - had to hold the home and power button down until it turned off.
Ive read on the forums that this is a common fault, and can occur to any iphone - faulty or otherwise. And the main concensus seems to be to take it back to the store for a swap.
My main question is - seeing how im likely to come across this fault again - is the fault software or hardware related?
If its hardware related what circuit board is likely to be the culprit? If we could identify the problem then im sure I could just order the required part on ebay.
The fact that apple havent recalled the iphone and that they will accept these faulty iphone's back and swap for new suggests to me its an easy fix - its just easier for the technicians to go in the store room and get a brand new one.
Secondly ive just got another iphone 4 white - bought cheap as its totally dead. Tried a new battery and still nothing. Got a new dock / charging connector on the way - is it likely to be this at fault? Doesnt seem to be any sign of water damage, and it wasnt described as this on the ebay page.
When id swapped the new battery over i tried to charge the phone ( to see if id fixed it ) and it got extremely hot - so i disconnected right away and left it to cool off.
Whats likely to be the issue with that one?
Thanks, and hope someone can help
AdamApple does not sell parts. There are no legitimate sources for iPhone parts. Apple considers iPhone to NOT be user servicable, and any attempt by anyone other than Apple to open or service an iPhone will void any warranty and forfeit all rights to have the phone serviced by Apple.
Your assumptions that a) the problem you have is widespread, and b) that it is an easy fix are incorrect.
If you want advice of repairing iPhones, try someplace like www.ifixit.com.
What you're doing is not supported or condoned by Apple.
By the way, almost every single case of an exploding iPhone or an iPhone catching fire can be traced to a botched 3rd party repair. -
I just got my MBP with 4g's of RAM after working with a PB 512 RAM.
So here's the deal. I still get the spining wheel often when opening and closing programs; render and export time is similar in FCP and iMovie;
and here's the clincher-when I check Activity Monitor during "RAM Intensive"
functions, it's like 2-3 gigs green.
I'm begining to feel as if RAM is not what it's cracked up to be?
Am I wrong?The best answer/explaination is that it really depends upon what you are doing. A couple of examples and a rule of thumb:
First the OS must have enough RAM to do its job. I'm not sure what the value is but Apple is selling MBPs with 2g of RAM. Lets say that is what is required to allow the OS to function and "typical" programs to run.
When you run a program it needs to be loaded into RAM. If there is free RAM then it will go there. If not then the OS does what is called swapping. It takes parts of programs and code that are not currently needed and moves them to a special disk file and then it loads your program into RAM and it begins running.
This swapping process is usually one of the slowest things Mac OS can do. If it has to happen at some point you generally see it with spinning beachballs and bouncing icons in the dock. Your computer is not dead, it is just working really hard to make space.
If you want to see this happen, open the program Activity Monitor and look at the memory usage and watch it change as you open more and more programs.
Adding RAM makes the need to swap much more rare.
But no matter how much RAM you have, how fast your processor is, all things still must go through the disk system. If you are loading big batches of data then it will take time.

How to create swap partition on my mac
Hi All,
I am very new to MAC OS and I have VMWare installed on my MAC upon VMware running window7.
And I am using Macbook Air with 8GB RAM the problem is I am running low RAM space and due to this system gets hugs all times.
Rather than upgrading to new lappy just wanted to enquiry is there a chance to create a swap partition ?
if it possible please let me the know the process to make it.
Advanced Thanx

Your Mac already has a swapfile, what is a swap partition?
Exactly what it sounds like. A reserved section of disk that is used for swap. Normally the fastest part of the disk (or a dedicated disk) is chosen.
The OS already handles expanding & swapping RAM to disk. It's only an issue on spinning disks, do you have an SSD Srinivas_Gadi?
I can't see how a swap partition can be that much faster, ultimately if RAM is still writing back to the same disk it will perform within it's capabilities. All the other disk IO will be slowing the process too.
See some of the old posts too…

A search of the MOS knowledge base turned up Support Recommended doc 1009494.1 How to use DTrace and mdb to Interpret vmstat Statistics.
The section titled "kthr: Swapped out Threads (w)" includes the following statements and commands:
To see the kernel threads swapped out during the sample period:
$ dtrace -q -n 'fbt::swapout_lwp:entry{ proc = (proc *)arg[0]->t_procp; printf("Lwp: %d of \t Proc: %s being swaped out\n",arg[0]->t_id, proc->p_user.u_comm);}'
The vmstat output doesn't tell what processes are swapped out. Mdb(1) can be used to print swapped out processes:
# echo "::walk thread myvar|::print kthread_t t_schedflag|::grep .==0x8|::eval <myvar=K|::print kthread_t t_procp|::print proc_t p_user.u_comm"|mdb -k
The dtrace command does not pass edit:
*dtrace -q -n 'fbt::swapout_lwp:entry{ proc = (proc *)arg[0]->t_procp; printf("Lwp: %d of \t Proc: %s being swaped out\n",arg[0]->t_id, proc->p_user.u_comm);}'*
*dtrace: invalid probe specifier fbt::swapout_lwp:entry{ proc = (proc *)arg[0]->t_procp; printf("Lwp: %d of \t Proc: %s being swaped out\n",arg[0]->t_id, proc->p_user.u_comm);}: syntax error near ")"*
The mdb command does not return any thing:
*#echo "::walk thread myvar|::print kthread_t t_schedflag|::grep .==0x8|::eval <myvar=K|::print kthread_t t_procp|::print proc_t p_user.u_comm"|mdb -k*

Swap constantly grows - but why?
Hello.
I've noticed that my system constantly makes the swapfile bigger but I don't quite understand why…
MacBook-Pro:~ alex$ du -sch /private/var/vm/swapfile*

64M /private/var/vm/swapfile1

3,5G total
If I sum up the amount of the physical memory shown by activity monitor, I end up with about 2.4 GB. I've got 4 GB RAM. Why is any Swap used at all in this case? And even more important: Why does it keep on growing?
!http://i.pgu.me/Vsava6Fi_original.png!
Thanks,
AlexanderBecause between the time you booted your Mac and when you look at /var/vm,
you ran applications that wanted more memory than you have phyical RAM.
And looking at your resident RAM usage is meaningless with respect to swap usage.
There is no easy way to figure out what is in swap.
Virtual memory is filled with empty holes, so that cannot be used
to measure swap usage.
And both virtual and resident RAM may be counting shared library code
so there may be double (or greater) counting of the same physical RAM page.
If you have 3.5GB of swap, it is because you peaked out at needing 3.5GB
of swap.
The more important question is, are you seeing a performance issue due
to swapping?
I like to start a Terminal session and run the following command:
sar -g 60 100
which will show pageout activity once per minute for 100 minutes
(adjust values to suit your tastes).
When you see jumps in pageout activity, you can cross reference
that against what you are currently doing.
Web browsers can be memory intensive depending on what web sites
you visit. Also photo and movie editors are very memory intensive. -
Protocol for swap install of files
When reaching the limit of physical memory, enter /sbin swapon -a.
What protocol exists for the entry of data into swap...lifo...fifo ...?
What data enters swap, already installed or newly installed?lilsirecho wrote:
Interesting, iphitus.
In my actual case, everything in Arch is in memory, Live Larch and that means it is categorized in various locations, opt, etc, var, etc.
What determines the modus operandi for the exodus to swap?
The data entering is one large GB file, contiguous data...video.
not sure how filesystems in ram are dealt with in terms of swap, or even if they are swapped. I suspect that kswapd doesnt discriminate or even know what things are taking up ram, it just swaps pages of ram that havnt been used, from certain zones of memory irrelevant of what they are.

Hello,
I have installed Max DB 7.6.03.16 on AIX 5.3, however when trying to create a database I receive following message:
-24994 Runtime environment error (db_admin -f); 1, Check knldiag! Kernel exited with '0' before reaching ADMIN state (OS error code 11000)
I have reduced the CACHE_SIZE parameter to 800 and still receive the error.
Any suggestions?
Below is the knldiag and the ulimit for the user creating the database.

Hi David,
see above. Did you try to reduce the number of tasks?
What about free memory on OS level? What about free swap space on OS level? Are there any kernel parameters to be set in AIX? I'm not very familiar with AIX as I come from Solaris. But on Solaris you can configure different parameters for max files open etc. using kernel parameters. Is there something similiar in AIX?

Faulty hard drive? Memory analysis
Hey
Been trying to figure out whether or not my new MBP's hard drive is faulty.
It's a 13" 2,56GHz (Core2Duo) with 4 GB RAM
Can you help me find out by "analyzing" these numbers?
I did this clean install and got these numbers - after the clean install, no extra software installed and no external HDD plugged in:
Uptime: 3 days
Load averages: 0,38 0,49 0,62
Page ins: 2,26 GB
Page outs: 384 KB
Swap-disc used: 3,0 MB
0,6 GB free + 1,4 GB passive memory / 4 GB total = 50 %,
when running 13 diff. apps, incl. Safari with 10 tabs open (a slight bit of Flash)
Hard drive sleeping turned off.
Numbers after doing doing a full restore from Time Machine:
Did a test, running 30 apps (pretty heavy ones too, like all iWork apps, FF, Chrome, Safari etc.).
Free memory was gone, but had 1 GB passive left at all times. Got a lot of page outs though.
See screenshot.
[URL="http://img30.imageshack.us/i/screenshotot.png/"]http://img30.imageshack.us/i/screenshotot.png/[/URL]
Not sure why my memory usage stays this, somewhat, high now when only having very few apps open.
Also, what about the SWAP disc number, is that bad?
After another 24 hours, just normal usage (no heavy multitasking at all):
See second screenshot
[URL="http://img402.imageshack.us/i/screenshot2ux.png/"]http://img402.imageshack.us/i/screenshot2ux.png/[/URL]
System does seem a little slow and i'm getting some beachballs
Hope you can help me out
Thanks in advanceWhat you've posted gives no indication of any problem with your hard drive. Indeed, it has hardly anything to do with your hard drive. OS X is busy managing RAM to allow all your applications to keep running at once, and that's about all that appears to be happening.
You may want to read this Apple article about the several different RAM usage states and OS X's RAM management strategies:

It may reassure you about the normality of what you're seeing. -
Installing SSD in GT60 Dominator
Hi,
I just picked up a new GT60 Dominator 3K Edition. The laptop did not come with an SSD installed, though I had a 240GB SSD from my old laptop, and I would love to be able to shift the OS over to the SSD and use the 1TB drive just for data and a few rarely used programs.
Anybody have any answers as to how to do this?
F3 system Reset/Refresh doesn't give me the option to install on a different drive, Creating a recovery disc using BurnRecovery software doesn't seem to work? Any solutions? What if i Swap the 2 drives over physcially inside the laptop, and use the different SATA ports, would that get me anywhere?
Thanks in advance?There's a number of different ways to do it, but here's my preference....
1. Make the MSI Burn Recovery (backup) disks/DVD's.
2. Before installing the SSD, ensure that there are NO partitions on the SSD. It needs to be unpartitioned so the Burn Recovery disks can set it up properly.
3. Remove HDD, Install SSD (into SATA3 location).
4. Install the OS and such using MSI Burn Recovery.
5. After setting up the OS and getting everything running properly, shutdown.
6. Install HDD into secondary/SATA2 slot.
7. Ensure that the BIOS recognizes both drives and that the SSD is set as the boot drive.
This is much longer than just attempting to clone, but I don't trust cloning from a HDD to an SSD. In the end, if/when it doesn't work, you'll end up doing this anyway. Personally, again, I know this works and it's how I would do it. Save yourself the headache.
IF MSI Burn Recovery isn't working, I'd contact MSI. Something might be wrong with your installation.

Solaris 10 Cluster 3.2 with 2 zones in a failover scenario
Hi
Looking for the best way to set up things for the following scenario
I have 2 M5000 servers with internal storage and a 6140 array for shared storage
I need to create 2 zones on each in a failover scenario (active /standby)
On Server1 3 out of 4 cpus for Oracle Database Server 11g and 1 out of 4 cpus for Oracle Application Server
On Server2 3 out of 4 cpus for Oracle Application Server and 1 out of 4 cpus for Oracle Database Server 11g
Database files will be placed on the shared storage. In case of failure of Server1 Oracle Database will fail over to Server2 and in case Server2 is down Oracle Application Server will fail to Server1.
Would a zone cluster using clzonecluster be better?if yes how can i achieve the difference in cpu power in case of failure.
where is best to keep the zone root path on the internal storage or on the shared storage?
What about the swap space for both zones?
Better use exclusive ips or shared will be fine?
Will it be better to have sparse zone installation for the zone or do the whole thing?
What is the best way to achieve the cpu assignments needed and how much should be left for the global zone?
Thanks in advance
vangelisHi Vangelis,
Building a cluster, requires some planning and understanding the concepts.
A good start would be reading some of the documents linked to in this url: http://docs.sun.com/app/docs/doc/819-2969/gcbkf?a=view

Design of DB which stores files and has a history.
We have a very simple requirement: Object 'A' might have several attachments. Attachment means either a physical file stored in the DB (max 10 MB) or URL pointing to a file in the web/network/anywhere. In case an attachment is a file,
that file cannot be updated. Attachments might be deleted.
We started with the following simple DB schema:
Then we realized that we need to have a History table for the attachments to track changes in the FILE_NAME and URL columns. (The file stored in the ATTACHMENT column cannot be changed, but its name can be changed). The whole row in the
attachments table might be deleted. So the initial thought was to create this table:
However, this design has one drawback – the same file is duplicated (stored in several places). Since the file once inserted, can never be changed, there is no point to store it in the history table every time its name was changed.
Option 1.
My idea is to leave this schema unchanged, but to change the logic a bit. Every
update in the ATTACHMENTS table should trigger copying only of ATTACHMENT_PID, TABLE_A_ID, FILE_NAME and URL fields from that table to ATTACHMENTS_HIST. The ATTCHMENT field is not copied. When the row is
deleted from ATTACHMENTS table, then all fields including the file itself are copied to the ATTACHMENTS_HIST table. As a result of this, we store the file only in one place.
See option 2 in the next message..
AlexeyOption 2.
Split ATTACHMENTS table into 2 tables (ATTACHMENTS_META and ATTACHMENTS_DATA) to store the file in a separate table. Files will never be deleted. As a result, we can safely remove ATTACMENT column from ATTACHMENTS_HIST table. We don’t
need it anymore because ATTACHMENT_ID will always point to the file:
Here ATTACHMENTS_DATA table has FK:
CONSTRAINT FK_ATTACHMENTS_DATA__ATTACHMENTS_META
FOREIGN KEY (ATTACHMENT_ID)
REFERENCES dbo.ATTACHMENTS_META
(ATTACHMENT_ID)
Because of this, the relationship between ATTACHMENTS_META table and ATTACHMENTS_DATA table is 1:1.
At first blush the idea possesses common sense, but on closer examination it fails because we cannot delete a row from ATTACHMENTS_META. Why? Because it is a Master table and ATTACHMENTS_DATA is a Details table. We cannot leave the detail
without master. (The data in the ATTACHMENTS_DATA never deleted.)
What if we swap Master and Details table? I mean if ATTACHMENTS_DATA is Master and ATTACHMENTS_META is Details. Well, in this case we can delete a row from ATTACHMENTS_META table and leave the corresponding file in the ATTACHMENTS_DATA.
So it seems that it solves the problem.
However, it raises another issue. Do you remember that instead of a file we can have URL? URL stored in the ATTACHMENTS_META table which is Details table in this case. And we cannot create a row in that table until we create a row in the
Master table. But we don’t need a file for URL attachment. So this solution will not work.
Eventually, option 2 has the following solution:
Here ATTACHMENT_DATA table is Master and ATTACHMENT_META table is Details. Optional (null-able) ATTACHMENT_DATA_ID column was added to ATTACHMENT_META table. It allows splitting PK and FK in this table.
Now the question: Which option (1 or 2) would you prefer? Can you suggest option 3?
Option 1
+ There are only 3 tables
- File is copied from ATTACHMENTS to ATTACHMENTS_HIST table before deleting from ATTACHMENTS.
Option 2
+ File is not copied.
- There are 4 tables.
- Relationship between ATTACHMENTS_DATA table and ATTACHMENTS_META table is 1:n which actually does not reflect the reality.
Thank you in advance.
