Excessive memory usage by app after moving to 8.1.7.8 drivers

Good day all,
I'm currently working with an app that communicates with an Oracle 8.1.7 database. The app is running on a WinXP system and the Oracle database is running on Win2K. After upgrading the ODBC oracle drivers the app utilizes from 8.1.7.6 to 8.1.7.8 a massive increase in the memory consumed by the app was observed.
e.g.
One of the functions of the app is to generate a statistical report based on data in the Oracle database. Running this report with the 8.1.7.6 drivers installed would cause an increase of ~20 MB in the memory allocated to the app process. Subsequent runs of the report would not cause the memory usage to increase beyond this point.
Running the same report with the 8.1.7.8 drivers installed cause an increase of ~130 MB in the memory allocated. Each subsequent run of the report causes another 130MB of memory to be consumed. This quickly results in performance hits as soon as the system starts paging memory and eventually leads to a program crash.
Any suggestions on what may be different between the two driver versions that might cause this behavior would be greatly appreciated.

Are you using the Oracle drivers or another vendor's ODBC driver (i.e. Microsoft)? Advanced Security should be transparent to the application...

Network stream fxp excess memory usage and poor performance

I'm trying to stream some datas à highspeed rate (3 channels à 1Mbytes/s) from my 9030 to my windows host. Because i don't need to use data on the rt side, i choose to forward FXP <+-,24,5> to my host throug a network stream.
To avoid data loose i choose to use a wide buffer of 6000000 with this buffer my memory usage grow from 441mo to 672Mo and my rio is unable to stream the data.
With sgl or double, memory usage is 441 to 491Mo and datas can be streamed continusly.
Anyone have encoutered this problem?

SQL Developer is java based and relies on the jvm's memory management.
I'm not aware of any memory leaks as such, but memory tends not to be returned to the system.
Queries which return large return sets tend to use a lot of memory (SQL Developer has to build a java table containing all the results for display).
You can restrict the maximum memory allocated by modifying settings in in <sqldeveloper>\ide\bin\ide.conf
The defaults are -
AddVMOption -Xmx640M
AddVMOption -Xms128M

Excessive memory usage with FireFox 3.6.8

Is it normal for the total memory footprint of FireFox.exe and Plugin-Container.exe to be 1.14GB (488MB and 651MB respectively)?
When first opening FireFox, it's footprint is approx 30MB, but inexorably creeps upward as I browse (typically YouTube/Hulu/4chan/GMail), consuming nearly 60% of total system memory before performance loss demands a browser restart.
Is there any workaround or update/patch or command-line argument that will cap memory usage? Will rolling back to an earlier version of FF solve the problem, or is it a problem with Flash? Any advice would be appreciated.

This is caused by the Flag Fox add-on, you can either disable or uninstall it.
# Open the add-ons manager - in the menus select Tools, then Add-ons
# In the add-ons manager go to the Extensions panel
# In the list of add-ons click on Flag Fox to select it, then either click on the Disable or Uninstall button
# Re-start Firefox to complete the process
Do you have Personas Plus 1.6 installed? If you do try disabling that one instead, it has been causing problems with add-ons.

How to reinstall apps after moving itunes files

I love my iPad.
I use 100+ apps and the iPad everyday for work en privat, sync several e-mail accounts, read books, edit photo's, and so on.
I synced my iPad on my PC in our netwerk.
At one moment I discovered, that it was part of my roaming profile. It had a negative effect on the performance.
So I moved my itunes files (Apps, music, film) as a map to another location to speed things (signing on a PC) up.
I cleaned my roaming profile.
Last week my iPad surpised me; it started as if it was brand new. Everything on it was lost. Why this happend, I'll still don't know. Anyone?
Syncing with my PC to get it back didn't work. I now have an iPad with no more than the standard apps.
My e-mail was available though. pff...
I copied the itunes files (I can see all my iPad as ios.apps) back to its origional position within my roaming profile.
I thought, that after that, syncing my iPad would find te files and restore them. It didn't!
Does anyone know a way to accomplice this?
I don't want te rebuy all the apps i payed for again. Some were realy expensive (Navigon)
Can anyone tell me were the files for the iPad have to be stored/placed/replaced and which files have to be there?
What files and which function they have?
I'm despared. Can anyone help me?
Thanks
Ted

Restore your iPhone with iTunes on computer. Very simple. If you have any problems, open iTunes on computer. Connect iPhone to computer. Hold both home and power buttons until iTunes recognizes iPhone in Recovery Mode. Usually takes about 20 seconds of holding both buttons. Click Restore Button of iTunes.

Updating apps after moving to new country

I have read the previous discussions but they provide no help for my situation.
I have moved from Sweden to Germany and now my (many) apps are not updating in iTunes. I can update any apps bought in the German store but any bought previous to my move a) do not show up in the purchased list and b) though iTunes tells me there are updates available I cannot update them.
I would expect all of my apps to be listed in the purchased list regardless where I bought them.
Also, it has been suggested I delete them all and reinstall from the German store but they are not all available form the German store.
Please advise me how I can untangle this terrible mess!
And please tell me when Apple will improve this aweful service. It really makes me long for an Android.

I think the whole Apple ID situation is a horrible nightmare, not entirely, but mainly Apple's fault. (Amazon is another 'global' player with national stores which don't sell the same things.)
I live in France, visit the UK regularly, speak French, but prefer to do my shopping in English (also there are apps I use when in England not available on the French store).
      Example:
      when in France I want the SFR app on my iPad
      when in the UK I want the iPlayer app.
I have one Apple ID which I use to got to the UK store and another to go to the French store. For each I give a different country of residence and a different bank card. I can't understand why I can't have one ID with different cards for the different countries. People do travel... ...
Syncing between my iMac, iPad and iPhone is a headache also, as I have to remember which ID I have configured on each device.
And don't get me started on global internet companies (Apple is by no means alone) which treat country of residence as the same thing as language of choice.
My 27-year love relationship with Apple is beginning to sour.

Memory usage is huge after upgrade to firefox 6

Firefox 6 chews memory like a big red rock eater eats rocks!
Consistently using 2gig of memory, make browsing slow as any thing. This has happened through all updates since version 6.
Tried on multiple machines and they are all the same.
Any fix for this?

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.com/kb/Safe+Mode
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
*Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

SQL Developer 3.2.09 and excess memory usage

This is really something that will ultimately end up as a bug-fix request, I'm thinking, but I was wondering if anyone else is seeing the same thing, before I report it.
We're using SQL Developer 3.2.09 in a Citrix environment, and we're finding that it's using up an inordinate amount of memory, causing performance problems for anyone else with applications open on the server. We haven't seen any patterns so far ... like if it's a side-effect of having the tool open for long periods of time (memory leak), or if certain activities within the tool are prone to using up too much memory.
Has anyone else experienced the same thing when running SQL Developer on their desktop, or in Citrix? And have you been able to tune it at all?
Thanks,

Excessively high memory usage by Tomcat in NT

We are facing the problem of excessive memory usage by our servlets (that call JNI functions). The memory usage seems to touch 50+ MB in 2000 Server but it drops down to 30 MB soon. But, this does not happen in NT. The memory keeps on increasing and there is a point in time when Tomcat occupies all the available memory.
We are taking care of garbage collecting the objects frequently(by calling Runtime.gc()). Is there any other way by which we can have some kind of control over the usage of memory?
Do we have to install a patch for NT (if something like this is available)?
NT Server:
PIII 500 MHz, 256MB RAM, 40GB HDD
2000 Server:
PIII 700 MHz, 128MB RAM, 20GB HDD
Tomcat:
Version 3.2.1
JDK:
Sun's JDK 1.3
Any suggestions, pointers are appreciated.
Thanks

Hi, Manish:
I've solved memory leak problem in JNI once. Memory leak may be resulted from inapproriate memory access in C or C++ library.
My previous problem is: I get a C byte array from Java byte array by GetByteArrayElements, however, I never call ReleaseByteArrayElements before C function return. That will let that Java byte array unable to be garbage collected. After inserting ReleaseByteArrayElements before return, it won't run out of memory again. Similar problems may happen when useless Java object's reference count not zero because NewGlobalReference without calling DeleteGlobalReference.
However, I've faced another problem in JNI (see http://forum.java.sun.com/thread.jsp?forum=52&thread=212275). I wonder if JVM release or reset memory allocated in C library. Hope it is not true.

David Wu

Premiere Pro CC 2014 60GB virtual memory usage

The longer Premiere stays open, the slower it runs and the more memory it uses until the system errors out and makes me close things.
Any ideas? 60GB memory usage seems ridiculous. The total footage size is only 10GB.
Running Premiere Pro CC 2014 and After Effects CC 2014 with dynamic linked files, app nap turned off.

Am having the exact same issue - premiere clogging up my system with excessive memory usage until I am forced to close things. Using most recent premiere update 8.1. Please help adobe! I'm on a deadline!

Why Does Safari Use Excessive Memory with Gmail?

I am running Safari 7.0.1 along with Maverics (10.9.1) on a 2011 MacBook Air with 4 GB of memory. Just recently I have begun to notice excessive memory usage when using Gmail. I have iStat Menus as well as something called MemoryKeeper so I can monitor memory use in real time.
The table below shows numbers taken from Activity Monitor with each of the sites running in a single tab. The Safari Web Content is through the roof with Gmail compared to My Yahoo or indeed with any other single site. In Gmail it starts out above 500 MB and slowly comes down to the lower end indicated if I do nothing. If I open tabs with both My Yahoo and Gmail, I sink below 100 MB and if I have three tabs open I'm heading to zero. As far as I can tell, the excessive memory useage only occurs with Gmail.
Process
Yahoo
Gmail
Safari
156 MB
167 MB
Safari Web Content
96 MB
531-338 MB
Kernel Task
464 MB
464 MB
Free
662 MB
210 MB
Typically I will close Safari and start it again if I get much below 100 MB. I usually have to close Safari at the end of the day to refresh it for the next day. This has only become a problem within the last month or so, and I am at a loss to explain it. I thought it might be Mavericks related (though I have been running Mavericks since its release), but then the Safari I have on my 5 year old Mac Mini running Snow Leopard gives me similar results.
When I run Google Chrome I don't have any of these problems. Indeed, though it is not my preference, I am having to use it more and more for day to day activities or I have to stick with one tab if I am going back and forth between Gmail and other sites. I have not seen this problem reported elsewhere, so I have to believe there is something going on in my system. I have cleared the cache one time on both systems, but that doesn't seem to have made any difference. I would appreciate any comments or suggestions.

I would not have even tried this app had I not heard about it on the Mac Rountable podcast (episode #222), where it received favorable comments from otherwise knowledgeable people. It also has a 4.5 star rating on the Mac App Store with 706 5-Star ratings out of 1,049. If you add up the 5-Star and 4-Star ratings you get close to 1,000 favorable rates right there. I have to wonder if people really know what's going on. Since the most obvious detrimental effects for me were centered around using Safari with Gmail on Mavericks, others must not be using that lethal combination. As I mentioned, using Google Chrome does not seem to have any obvious deliterious effects.
Well, there's going to be one more 1-Star rating reflecting my experience.

Mailclient memory usage

Hi!
I've been developing a supposedly lightweight email client for my own use, to learn java better. The problem is that when I run it, it is not exactly as lightweight as I'd like. It sucks up 20-30MB of memory, which I think is quite much, as at the moment it's not really more than a mail notifier.
Is this due to JVM overhead or because of poor programming on my part? If the latter, are there any guides or similar to avoiding the most common pitfalls of excessive memory usage in java?
//T
EDIT: the only GUI classes that I'm using (except for when adjusting setting and such) is a subclass of awt.TrayIcon
Edited by: ojve on May 10, 2008 9:50 AM

I doubt your code takes up 30 MB, so I would venture a guess that it is also showing the JVM.

CPU/Memory Usage increases when loading SWF files in AIR.

Hi,
We face the below mentioned problem. Would be great if someone could help us.
Due to problems with uploading the attachment here, please send a email to the following email-id ([email protected]) and I shall send the attachment in response.
CPU/Memory usage increases drastically while moving the SWC components and loading the SWF Files.
"Problem Description" - On executing the sample application, a window with multiple objects is shown. The loaded SWC components in flex consume too much Memory and CPU cycles. This is visible in TaskManager. On dragging one of the object, CPU / memory usage increases drastically.
"Steps to Reproduce" -
Draggable window is placed at the bottom in the sample application with Text indication.
Drag the indicated window.
"Actual Result" - System's CPU usage increasing drastically around 50% to 60 %.
"Expected Result" - Drastical increase in memory\CPU should not occur.
"Any Workarounds" - No"
Thanks in advance.

You can control your external swf from your main.swf in the following method:
loadswf(clips[0]);
function loadswf(tmp:String):void{
    passedString=tmp;
    ldr= new Loader();
    ldr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressListener);
    ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);
    ldr.load(new URLRequest(animPath+tmp));
    function progressListener (e:ProgressEvent):void{
        ploader.visible=true;
    function swfLoaded(e:Event):void {
        mcExt = e.target.content as MovieClip;
        ldr.contentLoaderInfo.removeEventListener(Event.COMPLETE, swfLoaded);
        mcExt.addEventListener(Event.ENTER_FRAME,onEnterfn);
        ploader.visible=false;
        addChild(mcExt);
function onEnterfn(e:Event):void{
    var num:int=mcExt.currentFrame;
    switch(passedString){
        case clips[0]:
            if (num==1) mcExt.play();
            if (num==9) {
               mcExt.skipmc.addEventListener(MouseEvent.CLICK,skipfn);
                function skipfn(e:MouseEvent):void{
                    mcExt.stop();
                   mcExt.removeEventListener(Event.ENTER_FRAME,onEnterfn);
                    gotoAndStop("help");
            if (num==mcExt.totalFrames){
               mcExt.removeEventListener(Event.ENTER_FRAME,onEnterfn);
                gotoAndStop("help");
            break;

Calcualte Oracle applications memory usage

Is there a way or does anyone have a script for oracle applications memory usage of a period of 30 days??

Hi
By implementing the statspack you can get most of the statistics information including memory usage of apps instance with time intervals. Since there is no GUI performance analysis is complicated with statspack. If you are on 10g a new feature called AWR(automatic workload repository) which gives you statistics and metrics with html format report.
There are some tools to monitor the Oracle applications services like cpu , memory consumption... I prefer to go with your own customization scripts to monitor the instance.
You can get plenty of scripts in the net.
http://www.orafaq.com/scripts/
I have little experience with bmcsoftware which monitors oracle Applicatons. But I am not sure whether it gives statistics for the timeperiod. See the below whitepaper of bmc.

Having a problem with Excessive "modified" memory usage in Win7 x64, upwards of 3.6GB, any suggestions?

I have 6GB of ram, a fresh install of Windows 7 x64, and the screenshot shows what happens after leaving my PC on for a couple days. (3782+MB being used by modified memory ATM).
http://wow.deconstruct.me/images/ExcessiveMemory.jpg
Any ideas on this?
Edit:
Added this after first round of suggestions
http://wow.deconstruct.me/images/NotSoExcessiveMemory.jpg
This is uptime of around 2 hours.
The first image is of uptime of around 3-5 days.

Matthew,
The only reason why these pages are kept on the modified list indefinitely is because the system doesn't have any available pagefile space left. If you increase the size of the pagefile the system will write most of these pages to disk and then move them from the modified list to the standby list. Standby pages are considered part of "available memory", because they can be reused for some other purpose if necessary.
Whether this would "fix" the problem or not depends on what the actual problem is. If it's an unbound memory leak then increasing the size of the pagefile will simply allow the system to run longer before it eventually hits the maximum pagefile size limit, or runs out of disk space. On the other hand, if it's a case of some application allocating a lot of memory and not using it for a long time, then increasing the pagefile might be a perfectly valid solution.
Allowing the system to manage the size of the pagefile actually works well in most cases. Pagefile fragmentation (at the filesystem level) can only occur when the initially chosen size is not large enough and the system has to extend it at run time. For win7 we have telemetry data that shows that even for systems with 1 GB of RAM, less than 0.1% of all boot sessions end up having to extend the pagefile, and this number is even lower for larger amounts of RAM. If you think you are in that 0.1% and your pagefile might be getting fragmented, you can manually increase its minimum size such that the total system commit charge stays below 80% even if you run all your apps at once (80% is the threshold at which the pagefile is automatically extended). This will make sure the pagefile is created once and then stays at the same size forever, so it can't fragment. The maximum size can either be set to the same value as the minimum, or you can make it larger so that the system is more resilient to memory leaks or unexpectedly high loads.
By the way, Windows doesn't use pagefiles as "extra memory", it uses them as a backing store for private pages, just like regular files are used as a backing store for EXEs/DLLs and memory mapped files. So if the system really has more than enough RAM (like in your second screenshot, where you have 3.6 GB of free pages) you shouldn't see any reads from the pagefile. You can verify this by going to the Disk tab in the resource monitor and looking for any disk IO from pagefile.sys. On smaller systems that don't have an excess of free pages you may see periodic reads from the pagefile, and this is expected because the total amount of data referenced by the OS/drivers/processes is larger than the total RAM. Forcefully keeping all pagefile-backed pages in memory (which is what disabling the pagefile does) would simply mean some other pages (memory mapped files, DLL code or data etc) would have to be paged out.
Regarding further troubleshooting steps: If the system runs fine with a larger pagefile (commit charge stabilizes well below 80%, and you no longer see gigabytes of modified pages accumulating in memory) then you don't really need to do anything. If the problem persists, you can check for any processes with an abnormally high commit charge, and also check kernel memory usage in task manager. If it's a kernel leak you can usually narrow it down to a particular driver using poolmon.exe or kernel debugger.
