Zfs cache vs. Physical and swap memory

On Solaris 10: We are calculating the available physical and swap memories by using these
@ system calls 'sysconf' and 'swapctl' with appropriate parameters.
I don'tthink these system calls explicitly take the 'zfs cache' into account.
Can you please confirm, Or do we have any other command set to include 'zfs cache pool' also.

Not exactly sure what you are asking - Total VM = Real RAM + swap. The ZFS arc (as well as the UFS cache) competes to get RAM, as does running processes and kernel memory allocation. The arc will not add anything to the Total VM amount.

ZFS file cache and available memory

In one of our application, we use the Solaris calls 'sysconf' and 'swapctl' with appropriate parameters to find out the amount of total and free physical and swap memories on the machine at any moment.
1. I would like to know whether these calls would account for the memory reserved for the ZFS file cache, in the sense, would the above calls consider the memory
that is a part of the ZFS file cache within the total/used physical and swap memory?
2. Would the ZFS file cache be accounted in the in the output of command 'vmstat'?

frankrinmelrose,
With only 1.5 GBs free on your HD, it is not surprising that you are having difficulties. In fact, it is rather dangerous to operate your computer with this little space. While later versions of OS X are much better at dealing with too-little disk space, there is still a risk that you could suffer a major disk error. This is a common and well-known problem, and could result in a loss of all your data.
I consider around 10 GBs of free HD space a good target to shoot for, but certainly no less than 5 GBs. This should give OS X enough "flex" space on the boot volume. If you are using all of your available disk space, it might be time to migrate some of that data to an external HD.
I could give a long-winded explanation of how inactive memory fits into this equation, but the short version is that it just doesn't matter in this case. In this case, Safari (following your example) has been given all of the physical and virtual memory it is ever going to get, and the issue is not with what physical memory it occupies, but with how the HD is being accessed.

Swap memory

Hi,
Version :10.2.0.1 and 11.2.0.1
Os :Aix 5/6
We often getting swap issues.It reached 95%.we have 120GB real memory and 45 GB swap space.The db size is 2.5TB.Some time the db went to hang state and we restarted the db.
DB level
Is it possible to find A QUERY which memory using whether real memory or swap memory?How much amount from it?
OS level
Is it possible to find how much memory A PROCESS using from real memory and swap memory?
Thanks.

Thanks.SWAP is an OS operation & Oracle has NO knowledge about it.
OS moves "idle" processes to free up RAM.
do like below & wait for the 1 minute data collection to finish.

I used to be able to download a lot of cd's, now I cannot download more than one or two cd's at a time. I am told that my 'cache' is full and I need to re-start iTunes to clear some of the 'cache' memory. What is the cache and how do I resolve this?

CD download problems:
I used to be able to download numerous cd's at a time but now I can only do one or two until I restart iTunes. I have been told that my 'cache' is full and will only empty a little a each restart. I did look at the properties and the 'cache' is showing full How do I correct or improve
this?

Final Cut is a separate, higher end video editor. The pro version of iMovie.
Give iPhoto a look at for creating the slideshow. It's easy to assemble the photos in an album in iPhoto, put them in the order you want and then make a slideshow of them. You can select from various themes and transitions between slides and add music from your iTunes library.
When you have the slidshow as you want use the Export button at the bottom of the iPhoto window and export with Size = Medium or Large.
Save the resulting Quicktime movie file in your Movies folder.
Next, open iDVD, choose your theme and drag the QT movie file into the menu window being careful to avoid any drop zones.
Then follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
The reason I suggest iPhoto is that I find it much easier to use than iMovie (except for the older iMovie 6 HD version). Personal preferences showing here.

Crash dump size too big (ZFS cache is counted as kernel pages)

Hi,
After a system crash, no crash dump was available: kernel size is 17GB ( ! ) probably because we use ZFS and ZFS cache is counted as kernel pages.
How to do not save ZFS cache in dump ?
Thanks.

I checked around with more collegues and the problem of the ZFS ARC that is included in the crashdump is described in BUG ID 4894692 (caching data in heap inflates crash dump).
This BUG is solved in Solaris 10 U4 or in the kernel patch 120011-14.
If you don't want that ZFS ARC inflates the crashdumps, please upgrade to sol10 U4 or upgrade at least to this latest kernel patch ...

Difference between free and inactive memory?

I'm really just wondering what the difference is between inactive, and free memory. Right now, I have about 13MB of free memory, and 381MB of inactive memory. Is the inactive memory just on reserve in case the computer absolutely needs it? Is there any way to utilize this "inactive" memory to speed up the computer? Thanks.

Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.

High Resident and Virtual memory for DBWR

Hello All
on 64 bit RHEL5 with physical memory of 98gb.
I see in OEM db console for 11gR2 database that dbwr processes is consuming 21gb of Resident and Virtual memory.
There are 3 dbwr processes (all using 21g) running and i see swapping happens even there is not much load on database .
Is it normal for dbwr to allocate such high memory ?
other memory config
sga_max_size big integer 60G
sga_target big integer 39808M
pga_aggregate_target big integer 10G

That is an excellent document.
The one thing you have to remember when looking at memory usage of Oracle processes, is they all attach to the same set of shared memory so your values will look high. For example if you assume your sid is XE and run the following command you can get something like this.

ST22 Swap memory problem

Hi all,
I having problem in BI 7.0 server for swap memory goes to RED color... I know some variables and paramaters, but I am not sure how to calculate (depend on 12GB physical memory)
Screenshot here... if anyone know how to fix that I really appriciated
http://www.flickr.com/photos/38842895@N04/4538676180/sizes/o/
Thank in advance

Double click on the red highlighted swap, now click on current parameters.
Here you can see which parameters designates the memory for this buffer area. Once buffer is exceeded it begins to SWAP.
this is not a bad thing unless you are seeing performance problems. Most performance problems are far deeper than this.
You now need to research the overall memory usage and decide whether to increase the parameter and possibly decrease others.
use ST06 as well for overall usage amounts of swap.
There is much to understand but you can start by reading here:

Swap memory always at 0

Hi i recently re-installed arch and last time i've created a swap file that works perfectly, but this time i followed every step on the wiki but the swap memory use is always at 0. Even if the ram use is over the 60%
Anyone has the same issue?

i simply suposed it. My bad.
Anyway i try what Scimmia sugested and put swappiness to 100 and i got the same answer
I paste my console history

Swap memory & CPU rules

Hi people,
I need the requirements for choice the amount of CPU and type, and the rule to calculate the amount of swap memory of productive system. The amount of physical memory is 12 GB RAM.
In the installation guide says that PHYSICAL MEMORY+ 14 GB= Swap memory. Is this avalaible for productive system.
More thanks.

Ruben this is quite a frequently asked quetion...
Basically if your system is Unix based the thumb rule is that SWAP should be 3 times your physical memory (been 12 gb it shouldn't be much of an issue). In windows 64bit usually 20Gb of swap (pagefile) is enough for most installations
There is info at help.sap.com about this.
Regards
Juan
BTW, why won't you trust the info on the installation guide?

-- mod edit: read this is the right subforum, but it was the most relevant available.
which is plenty for me even though i use alot. There's an issue however, and that is that many heavy applications such as games like Garrys Mod or Elder Scrolls Online under Wine crashes when the RAM cache exceeds those 6gb. It's supposed to go over to SWAP, but heavy applications simply just crash instead which is very annoying. I do not know why it just crashes, since i always have at least 1500mb of free swap available, and since it's just for cache and not reserved memory that should be fine. Sometimes an excessive amount of cache is used, and i'm not sure what is using up all of it which makes me have to reboot my computer to be able to play games without crashing which is very annoying.
a ps aux of one of those times where excessive cache is used for unknown reason

Not a fix, but got my system to be more stable atleast.
Wrote a bash script that simply clears cache every minute. Very dirty, but it's better to have a stable and slow system than a system that crashes from time to time.
while true; do
echo 3 > /proc/sys/vm/drop_caches
sleep 60
done
simply execute as root and you're good to go.
Will continue to try to find the root of the problem though.

Satellite S50T-B - Adding RAM and swapping HDD for SSD

HI there,
I have recently purchased the Satelitte S50t-B laptop and have a few question about upgrading:
1. What is the recommended RAM to add (8GB)
2. What is the recommended SSD to add?
3. Are there any instructions to add RAM and an SSD to my laptop?
4. Will I void my warranty by installing more RAM and swapping the current hard drive for an SSD?
Thank you for your help

This notebook is listed on Toshiba page:
http://www.mytoshiba.com.au/products/computers/satellite/s50/pspq8a-008008/specifications
- What is the recommended RAM to add (8GB)
The unit supports 16GB RAM, so you can add an second PC3-12800 8GB DDR3L (1600Mhz) SO-DIMM module (i.e PA5104U-1M8G)
- 2. What is the recommended SSD to add?
Its up to you there are different SSD drive on the market and most of the 2.5 SATA SSD drives should be compatible.
- 3. Are there any instructions to add RAM and an SSD to my laptop?
It looks like both parts (RAM as well as SSD/HDD) are not user upgradable since there is no separate access to the memory or HDD bay. This means that whole plastic cover at the bottom of the unit needs to be remove in order to get access to these part.
But as far as I know this would cancel the device warranty!!!
- 4. Will I void my warranty by installing more RAM and swapping the current hard drive for an SSD?
If you want to keep the warranty valid, such upgrade should be performed by authorized engineer.

Mac OSX Lion 10.7.4 and Parallels (memory issues)

I bought a 2011 Macbook Pro i7 2.2ghz with 4gb of ram, 5400 rpm 500gb hard drive. Base 15 inch model pretty much.
I actually purchased it for a few reasons. 1) I had a 1200 dollar credit at a local electronics store and 2) I figured the battery life would be decent and 3) I was interested in playing around with Mac OSX a bit more.
Long story short I still need to use windows for various applications and for work. So I purchased Parallels since it seemed to have pretty good reviews and installed Windows 7 in one and Windows XP in one. Giving them 2gb for 7 and 1 gb for windows XP. Now since I knew I wouldn't have enough ram, I upgraded my ram to 8gb and upgraded the hard drive to a 7200 rpm.
So this is where my problem is, I am unable to run both of them at the same time without Mac running out of memory and swapping like no tomorrow bringing the entire computer to a halt.
In general Lion seems to be pretty slow, even without any virtual machines running. I have done a reinstall of the entire OS, repaired permissions etc.
So at this point I think I have come to the conclusion that the only solution is to again get more memory and go up to 16 gb, which is crazy in my opinion. I also installed Windows 7 in bootcamp and then installed Vmware workstation and I can run 4 virtuals (1 windows 7, 2xps and a win2k3) before the base OS gets really sluggish, so it isn't the hardware, it is simply the OS.
Case and point is my other laptop a Lenovo W700ds (for anyone who has seen this thing, it is a beast and has horrible battery life.. one of the reasons I wanted the Mac) runs a core2quad and has 8gb of ram but I usually keep 3 virtuals up without any hit to Windows 7. But it also only gets 30-45 minutes of battery life, while my Macbook Pro gets about 2-2.5 hours of battery life with the virtuals running however everything runs like crap so I usually have to suspend and only keep 1 at a time open.
My question being simply, is this normal? Should better hardware have such poor performance or am I just expecting to much? At this point my options are to install Windows 7 native (which i'd rather not do, I actually do like some of Lions features) or am I forced to buy even more ram?
I was also thinking of getting rid of the superdrive and moving my main drive there and then getting a 256gb SSD as the primary. But it seems to me at this point I am just dumping money into something that should already do what I want. This would split the hard drive access load though.
Any suggestions?
Thanks

Honestly I would never run both Win 7 & XP at the same time in a VM. 7 needs at least 4GB to run properly and uses more resources then XP.
I personally use VMware Fusion and XP. At this time there is no software, that I'm aware of or use, that does not run on XP. So for my Mac Win VM purpose I only run XP with the software in need to use in Windows. This work very well for me. I have 2 CPUs and 3GBs of RAM assigned to XP. Leaving the other 2 CPU cores, 4 HT cores, and 5GBs of RAM for OS X.
Not sure why you need, or want, to run both versions of Windows at the same time. I don't see the need as stated above.

Jrockit crashes due to outofmemory and illegal memory acces

Hello,
We have been using jrmc-3.1.2-1.6.0 and lately we are seeing JVM crashes after every couple days. Note: We have been seeing these crashes recently , for last 1 year we did not see such crashes.
Following are different issues that we have seen over last few days:
1. Crash due to illegal memory access
2. Crash due to out of memory error
3. Sever becoming unresponsive/Idle
For illegal memory access and out of memory crashes, there was jRockit dump file created and Dump file seems to be pointing at Jrockit libjvm.so module for the exception/crash.
Any help would be appreciated!

From the command-line (-Dehcache.monitor.enabled=True) you are using some form of caching.
The out-of-memory occured as the JVM was unable the allocate an object: C Heap : 1 memory allocations have failed
Could you check how the live data set is going (or the memory leak detector)
Some concerns with regard to tune a JVM that runs a cache can be found here: http://middlewaremagic.com/weblogic/?p=7083
Note that the example given discusses Coherence, but can be adopted for another caching mechanism as well.

Safari is running very slow. I have cleared cache, reset safari, and put in new DNS 208.67.222.220 runs worse now.
