Impdp and available memory

Just a quick one on how available memory can affect datapump imp.
Will increasing the SGA from 2GB to 8GB of a database on which data is being imported affect the total import time?
Just a bit curious!
Thanks

Hi,
What is the method of the Import Method. Whether it is External Path or Direct Path. If it is Direct Path it will not use buffer cache, it will directly insert after the HWM. If it is External Path it will use the SGA. I dont find a point to increase the size of SGA for the import process alone. If you have a luxury of having 8GB instance for import process you can have it for the normal databse operations too. Rather you can do the import process on the less peak time or you need to address the below questions to increase the size of SGA for this process
1) how much data are you going to insert?
2) how many users are going to be connected to the Oracle database when import is going to happen?
3) how big is your improting data and how it wll affect the performance
You can go for direct path insert which will be faster than the external path
Thanks,
Vijay

Smart paging Question , What happen if i don't enable smart paging and available Memory is about 1GB and the VM need 3GB for Booting ?

Hi ,
I configure a dynamic memory With 512 MB for a VM , and available memory 1GB
what happen when I boot the VM , While it actually need 3GB for booting - Note I don't configure Smart Paging ?
Thanks.

You won't be able to boot at all.
pagefile and dynamic memory only comes into play when you don't have enough memory on the host, to support the 'startup RAM' on the VM, and when the VM does a
reboot.

IPad available memory NOT consistent with available memory shown in iTunes and available memory reduced after a connected sync...doesn't make sense.

I was looking through my pictures on iPhoto on my iPad 2 and noticed in some of my albums there were duplicate pictures, but on iPhoto on my iMac there wasn't. I had also noticed that my 64GB iPad 2 had only a little over 14GB left for available memory. I decided to connect my iPad2 to my iMac and sync it with itunes but this time I unchecked Sync Photos. I was asked to remove photos which I agreed to. My intnet was to re-install my photos in hopes that I would no longer see the duplicate photos and quite possibly free up some memory. In short, none of that worked and instead the pictures remained on my iPad2 and my available memory jumped to 956MB. I then tried selecting a " Selected Events, Faces, Albums..." in the Photo section of iTunes but I did not select any albums or events or faces. The sync ended and I still had all of the pictures on my iPad2 with 7GB left of available memory showing on my iPad2 but now showing 12GB on my iTunes on the iMac.
I then tried to do a sync again, syncing all photos and the sync cancelled. I tried it again and it went through. This sync ended with 14GB of available memory showing on iTunes on my iMac, BUT on my iPad2 it showed 7.1GB.
None of this makes any sense. I guess I could have left it alone and viewed duplicate photos but if duplicate photos were causing available memory to be reduced, I wanted the memory to come back up for future use.
Also, I noticed that the amount of photos being synced has randomly changed on a couple of these occassions as if I had more or less photos to sync and I haven't. I'm not sure what would cause this either.
Where it says "Other" in the memory bar in ITunes on my iMac is 26.34 GB. Before I did the first sync it was a little over 7GB. What would cause the "Other" to consume so much memory? and what is "Other" Why did it fluctuate so drastically when I've made no changes to my iPad?
I hope I can get some help to this.
Thanks!

"Other" can be the cause of this storage capacity snafu that you have going on with your iPad. "Other" is pretty much what it sounds like it should be with regard to what is stored on your iPad. It is "stuff" associated with apps but not the apps themselves or any other media. It consists of Safari Bookmarks and history, Notes, text messages, email messages, contacts, photos associated with contacts and items of that nature. It should not be anywhere near 26 GB and the fact that you have much is a little bit of a problem.
Sometimes the only way to rid your device of that bloated "other" is by restoring as a new device without using the backup. There could be something corrupt on your iPad and if you restore from a corrupted backup, you will just end up back where you started. Also, sometimes this issue is caused by syncing photos and while I don't know this for a fact, it might have something to do with the metadata associated with the photos that gets corrupted and then that might cause this "other" storage problem.
Take a look at some of these and see if something in one of them helps.

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.

Available Memory displays 2 devices. Is this right?

Hi, I'm new to this format, and hope someone can help.
I've done a hard reset on my T5 after saving my data to my MAC. Before adding anything back, I'd like to see if I've got a problem or am good to go. On the screen that shows battery level and available memory, I'm seeing two devices, one reports 97% and the other 85%. After doing a hard reset, I expected there be only one empty (but for OS data) device? What have I done wrong, and more importantly, how do I proceed?
Post relates to: Tungsten T5

CLose. The T5 has a built is storage card. Like an SD card built into the device. This shows as separate memory. One is the device itself, the other is this built in storage card. If you inserted a SD card, there would be three devices showing.

My iPad is double downloading iTunes TV series shows and when I delete, the extra show does not delete from the available memory. I have lost almost 30GB of my 64 to this phantom shows.

I am losing available memory on my iPad (64 GB 3rd gen) and it appears to lose memory because some TV shows that I have downloaded from iTunes are appearing twice in my downloads. Both download, but when Only appear as 1 show on my "videos". After viewing the show, I delete, but the duplicate show appears to be still there somewhere (not visible anywhere) taking up the same amount of memory that showed before downloading. It reduces my available memory to download other shows. The general settings do not show any of these phantom shows taking any memory, but the total available is much, much less than what is showing for all usage such as music, videos, photos, apps, etc
Is it possible to delete a show from the download portion of iTunes if you have already seen a show and do not want to waste time or memory downloading again? The only way that I know is to let it download completely and the delete from "Videos".

John0618. Did you ever get a response or solution to problem? I have the same problem (starting about three months ago).

Issue with turning on project 2010 / 2013 - "There is not enough memory to complete the operation. To free up available memory, close programs, projects, or windows you aren't using, and then try again."

I get the following error after the installation and configuration window of MS Project: "There is not enough memory to complete the operation. To free up available memory, close programs, projects, or windows you aren't using, and then try again."
It happens both with MS Project 2010 and 2013 on a Windows 7 desktop.
I tried installing / uninstalling Office 2010, MS Project, tried installing 32 and then 64 bit versions, clean up, disk error checker, startup changes (msconfig), anti virus, running as Windows 7 and then Windows XP compatible mode.
Nothing helps. I see this issue reported as early as 2007 version of MS projects on Microsoft forums, but I do not see any solution anywhere. Any suggestions on how to fix the issue without having to reformat hard drive? Every other application, including
all other Office programs work seamlessly.
I also tried Microsoft support, after an hour and a half of basically doing what I did before, I was told I have to pay 99$ for "premium" support, so someone can look at this bug.
I have 16 Gb RAM and more than 200Gb or hard drive free, so actual memory is not the problem.

This issue was originally reported with MS Project 2007 and keeps popping up since.
A quick Google search provides more than 200K pages of results of this issue:

Computer was defragged already. I run more tests, and specifically when MS Projects tries to run, it tries to take all memory, more than 300Gb, on the computer. (DropBox was running at the same time, and warned that there were no space. As soon as MS Project
stopped attempting to configure itself, everything came back to normal and the available space became available again.)
Looking through older forum posts, looks like this application tries to take "unlimited" amount of memory. Some registry fixes are mentioned potentially, but I was not able to apply them.
Since everything else works, this is a MS Project bug reported by multiple users on various versions of Windows, including Vista and 7, so please provide a fix and not 'not a know bug' lie. All the premium support will say, is to format the hard drive, unless
they have a patch or a registry edit solution. If the latter is true, since the issue exists for multiple years, it should have been already been provided to users.
Also, I am not running a SQL server, or any server, this is an installation on a local machine.

I have an iMac OS X ver 10.7.5. Processor speed is 3.06 GHz intel core i3, and the memory is 4 GB 1333 MHz RAM. My online banking app is being updated and requires OS ver 10.8 or newer.

You can update directly to Yosemite (for free) through the App Store (this is 10.10). Make sure your existing applications will run on this OS.
If you wish to stay at 10.8, you can order this through the online Apple Store (it's $20), and they will email you a redemption code to be used on the App Store.

Hi, I have Mac with Snow Leopard and was trying to purchase Lion , so I can move to I cloud, when trying to buy the app I get a message that a minimum 2gb of memory is required. I went check the hard disck info and it says available memory 20gb :-(

Apple Logo, left hand side of the menu bar, About this Mac. It should be right there. If not then More Info, Sys Info.
But it would seem you don't have 2GBs installed and more then likely both RAM slots are already filed. So you just need to buy more RAM in a pair. That could be 2 1GBs chips or if your Mac can have more then that then 2 2 GB chips or 2 4GB chips.
Get your model # and go to Crucial.com and use their memory search to find out how much your Mac can have installed and the price for it. I suggest you install as much as it can take. Cost is very low on RAM these days.

I cannot backup because no more storage is displayed when the storage statistics shows Total Storage 5GB and Available Storage 5GB - basically i haven't used any memory but i cannot backup! please help

i cannot backup my iphone4s because no more storage is displayed when the storage statistics shows Total Storage 5GB and Available Storage 5GB - basically i haven't used any memory but i cannot backup! please help. i am only trying to back up my notes and contacts. that's it. and i don't think it will use up 5GB

On your iPhone, go to Settings>iCloud>Storage & Backup>Manage Storage. There you should be able to see how much of your used storage is allocated to different things (ex., iphone backup, ipad backup, mail). From there you should be able to figure out what is going on.

Sap server uses PF usage and not taking up the available memory

good day basis experts,
I have 16BG of total physical memory on my server. I set parameter phys_memsize to 8192 to allot the rest for my database. but it seems the server eats up PF usage instead. It eats up upto 18.3 BG and I still have 11GB available memory. I wanted my server to consume the available memory instead of PF usage. How can I do that? Should I increase phys_memsize parameter?
I know I should try this for me to know the ans but the issue is on our PRD so i cant just do resets.
Thank you for your help

Hi,
but it seems the server eats up PF usage instead. It eats up upto 18.3 BG and I still have 11GB available memory.
That's the way the SAP memory management system is designed. This behaviour is perfectly normal.
At start up a lot of shared memory is allocated directly in the PF.
By the way, in my opinion you have allocated too much memory for the DB and not enough for SAP.
On a 16Gb server, I usually allocate 4 GB for the database (PHYS_MEMSIZE = 11 GB) at the beginning. Then I tune the system depending from its use and load.
Regards,
Olivier

PCI 5112 and fetch more than available memory

I regularly have 15 MB of Available Memory - Should I upgrade or is there an issue I should solve first? EtreCheck report pasted below

Hello,
My MacBook is running super slow. I downloaded Memory Clean from the App Store and I regularly have 15MB or free memory available.
In Activity Monitor I usually see the following:
~800 MB kernel_task
~500 MB softwareupdated
~500 MB Image Capture Extension
In Console, I see mdworker.bundle errors attributed to UID's: 501, 503, 1422
My current UID from what I can tell is 502. Other UID's left over from various upgrades are 89, 99, 235.
Lastly, Drive Genius is giving me a Drive Integrity Warning. But I can't create a bootable clone.
I have no idea if the above problems are related. I'd like to think I just run a lot of stuff that eats my memory and upgrading the RAM would be the easy path. What say you all?
-Jeff

Will Installing more RAM improve performance, IF laptop has "available memory" not being used?

My laptop has 2x 1GB of RAM.
Right now, and usually, The Physical Memory shown in Task Manager, shows that there is "available memory" (currently it's 500megs worth). (And "system cache" says 300megs.)
There is also, right now, 2.5GB of page filing being used.
If I were to replace the 2GB of RAM with 4GB (of the same Mhz), would there be a noticable increase in performance?
(windows XP 32bit OS)

A matched set of DDR2 ram will perform a lot faster one memory not matched. Its required for the double data rate to work. Hence 2+2 is the max you'd need/want in a 32bit machine. Windows 7 was built for large memory footprints. XP was built to run just barely in 64MB but really needed a min of 128MB to support a network connection and printing. It was never enable to truely go a whole lot further than a few machines built capable of 1GB. There was even a bug which was patch causing problems if a !GB or more was available. Just because it can see it does not mean it actually uses it !! The kernal by default is swapped in/out of ram even in larger memory systems. Why, it was is not aware of the extra memory and does not change its behavour from a 512MB machine.
As for the 1333Mhz ram the timing may be faster than the other memory used. Hence it flow the data faster on the bus. Fewer delays in various cycles including the RAS/CAS etc but thats all under the hood so to speak.

K9A2 Platinum and 4 Memory Modules

Hey gang, the saga continues.
BIOS 1.2
With Vista Enterprise x64 SP1 RC and 4x DDR2-800 OCZ modules (see my signature) my system will POST but not boot properly (even in safe mode!) at either 3-4-4-15-2T-2.4V or at 5-5-5-15-2T-2.4V. It gets almost to the point where it wants to bring up the vista logo after loading all the drivers however then the screen resets to "no signal" and the system reboots from POST.
I removed 2 of the memory modules, leaving 2 in the slots closest to the CPU. At 3-4-4-15-2T-2.4V (which is what the memory is rated for) the ATI kernel driver gets a page fault during load, blue screen, memory dump. However at 5-5-5-15-2T-2.4V the system is stable. I expected 2 memory modules to work at the rated speed of the memory. I expected 4 memory modules to work at looser timings. I'll try 5-5-5-18-2T-2.4V with 4 modules just to see.
I'm getting 8GB/s throughput in Sandra XII at 5-5-5-15-2T-2.4V.
With BIOS P.0D I was getting 9.5GB/s at 5-5-5-18-2T-2.3V with the mushkin XP8500.
Maybe P.0D doesn't have the erratum in it, and tighter memory controller timings.
Oh and the Sandra disk benchmark test posted a RAID0 score of 140.5 MB/s throughput. WD360JD was 55 MB/s. I need to run a better benchmark though. I bought EVEREST Personal Ultimate, maybe it'll have something more useful in it. I can tell you the EVEREST benchmarks for memory performance on my system absolutely suck. They're pinning it around midrange in all the tests. :< I cannot run HDTach on this system because it doesn't recognize me as an Administrator (although I am one).
I have my final water cooling parts arriving on Wednesday - an inline temperature sensor which will hang right off the egress on the video card stack, for accurate CPU + video card heat levels on the liquid for the fan control.
At idle this system keeps the CPU at 99F temp, HD at 105F (I removed the front case fan, it would probably be cooler with it in there, but slightly noisier). Memory therefore is probably around 102F. I haven't gotten to stress testing yet because of the stability issues.
I also am trying Catalyst 8.1 beta to see if CrossFireX will work.
** At least the system is POSTing BOOTing **

AaronYuri: Using Vista Enterprise x64 SP1 RC, no fixes come up through Windows Update, I assume I have everything... point me to something that wouldn't be in the service pack RC?
Quad: So you think with an X2 CPU this wouldn't be a problem, but the Phenom is inferior?
Russ: I'm using fixed memory voltage as specified in the test. 2.4V and 2.1V. Both of which should have worked. Since I can do DDR2-800 2x 3-4-4-15-1T-2.4V stable (running Prime95 now...), I would expect to be able to do DDR2-533 5-5-5-18-2T-2.1V. Also this board originally posted with the memory at DDR2-1066 5-7-7-20-2T-2.4V so I know the memory isn't the issue.
One additional comment I would like to add to this discussion is that with all 4 memory modules loaded I can install the Vista operating system. It is only after I reboot, after the initial install, that it won't complete the boot cycle any longer. So the install boot works (which is probably a limited kernel?) but the real thing won't work.
As for DDR2-400 I might give it a try but I have to say if that's the only way I could do 4gb memory, I wouldn't do it.
Hello, I have the SAME sort of problems except with the K9A Platinum
Here is the fix/update they are talking about
http://support.microsoft.com/kb/929777/en-us
I have applied it and did not work for me. You are getting a BSOD likely. Boot to 2gb, go to System Settings under Control Panel. Click Advanced Setting on the left. Then click Settings button under Startup and recovery. UN-check automatically restart. You may then see the BSOD when you try booting with 4gb again.
I a using latest bios on my MSIK9A and I still cannot boot Windows to 4gb.
I have read thru all 20 pages here:
http://forums.microsoft.com/technet/showpost.aspx?postid=1292561&siteid=17&sb=0&d=1&at=7&ft=11&tf=0&pageid=10
Even though I do not run 64bit, this still seems to be a very common problem with running 4gb on 32bit and 64bit. It is not just a Windows problem. I have read Linux has exhibited this as well.
I even did a clean install of Vista on a spare drive last night with only 2gb installed. I then updated all drivers in order and then applied MS Hotfix I linked to above. I shutdown, put in all 4gb and BAM!! same exact BSOD. I have tried setting timings to many different settings. I have tried all "suggested fixes" to no avail. All 4gb of Memory all passes memtest86 v1.7 scans. Ran 17 passes overnight and all passed.
