R12 Memory needs

Hi all,
I'm installing R12 on my OEL4 box for learning purposes. My motherboard will only support 2gb of RAM. I see that kernel.shmmax needs to be set to half the size of physical memory, and at least 2gb. This would lead me to believe that I MUST have at least 4gb of RAM. Is this a cast-in-stone rule? This machine will have a max of 1 concurrent user, will only run what is needed for R12, and performance is not a real concern.
Thanks!
Scott

Hi Scott,
I've accidentally created a single-node R12 instance on a server with only 2GB of RAM available. :-) It ran fine, if a bit slowly, for a single user.
Michael Taylor (mdtaylor) offers a quick description of how he dialed down the memory consumption of an R12 instance to squeeze onto a laptop with 2GB RAM: Re: R12 Install under Linux

Runnable Class doubles memory need of application

Hi
I use a class called DisplayTimer to throw an event every second. This class is Runnable and runs as an own thread. Then I have OrientedText2D Object in a java3d environment that listen to these events and update their caption (countdown time) every time they receive an event. So far so good, the solution works. BUT the memory need of my application doubles when i .start() the Runnable DisplayTimer class to start the event-throwing for the countdown captions...
Here is the DisplayTimer class:
import java.util.*;
import de.qtobe.events.*;
import de.qtobe.tools.*;
public class DisplayTimer implements Runnable {
    private List _listeners = new ArrayList();
    Thread t;
    public DisplayTimer() {
        t = new Thread(this);
        t.start();
    public void run() {
        while (true) {
            _fireUpdateNotificationEvent();
            //Runtime r = Runtime.getRuntime();
            //System.out.println("before: " + r.freeMemory());
            //r.gc();
            //System.out.println("after: " + r.freeMemory());
            try {
                Thread.currentThread().sleep(900);
            } catch (java.lang.InterruptedException e) {
                Log.log("Error in DisplayTimer occured.");
    public synchronized void addUpdateNotificationListener(UpdateNotificationListener l) {
        _listeners.add(l);
    public synchronized void removeMoodListener(UpdateNotificationListener l) {
        _listeners.remove(l);
    private synchronized void _fireUpdateNotificationEvent() {
        UpdateNotificationEvent updateNotification = new UpdateNotificationEvent(this, false);
        Iterator listeners = _listeners.iterator();
        while (listeners.hasNext()) {
            ((UpdateNotificationListener) listeners.next()).updateNotificationReceived(updateNotification);
        updateNotification = null;
        listeners = null;
}This is how the listeners react:
    public void updateNotificationReceived(UpdateNotificationEvent event) {
            if (this.impactInfo != null) {
                //Ausgabe kommt in die "Machine"
                //String caption = "Remaining service time: " + this.impactInfo.getFormattedRemainingServiceTime();
                //caption += ", Countdown to breach of contract: " + this.impactInfo.getFormattedCountdown();
                String caption = "" + this.impactInfo.getFormattedCountdown();
                caption += " (remaining fullfill time: " + this.impactInfo.getFormattedRemainingServiceTime() + ")";
                this.setCaption(caption);
                if (impactInfo.getCountdownBreachContract() <= 0) {
                    this.setCaptionColor(Def.COLOR_RED);
                } else {
                    this.setCaptionColor(Def.COLOR_HOTRED);
                caption = null;
            }The events transport no information or data btw.
Does anyone have an idea how I can optimize this solution?
Thanks in advance!

The common understanding is that the swf is loaded into memory at once and in full, and so embedded assets take up initial memory based on how much they contribute to the SWF size even before any of them get instantiated into their runtime class form. This is certainly the case for Android or desktops that use the SWF, it isn't clear if the native iOS compiling ends up treating the embedded assets memory footprint in the same way or not, but possible.
There is a compiler flag which you can add called -size-report=report.xml that can give you a complete breakdown of how each type of data within the SWF contributes to the size in compressed form. It is most likely this memory footprint that contributes to loading the SWF (independent of actually instantiating or hydrating any of the embedded assets).
http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf67110-7ff4.html#WS19 f279b149e7481c45454d9412c561d3223-8000
There most likely are others here that know more details or might even want to correct some of these assumptions, but that is why most mobile developers choose to load assets from the filesystem if possible as opposed to embedding assets to avoid the extra memory hit on the initial SWF loading into memory.

My MacBook pro 2012 Mountain Loin 8.2 don't clear the inactive memory automatically when memory needed for other program so I get page outs.

My MacBook Pro 2012 Mountain Loin 8.2 doesn't clear the inactive memory automatically when memory needed for other program so I get page outs. There are much inactive memory when page outs. Why my mac does this?

That's completely normal. If other programs require memory then the system will reallocate Inactive RAM as needed. Page Outs don't mean anything.
About OS X Memory Management and Usage
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.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

More Memory Needed???

I have recently upgraded to Leopard on my iMac G5 with 512 MB Ram. Since the upgrade my Mac has been running slowly. If I try to run several programs, it sometimes takes a very long time for a program to come up. Also, often the fans will run very loudly.
I suspect that I might (?) need more RAM. What are your experiences running Leopard with 512MB? Should I buy more RAM?
Thanks for your help.

512MB is rather tight for memory these days.
Try starting an Applications -> Utility -> Terminal session and run the following command:
sar -g 60 100
This will give you pageout information every 60 seconds for 100 minutes.
Now use your Mac as normal. After using it for a while, go back to Terminal and check the pageout numbers.
If a 60 second interval is too long, then change the command to
sar -g 10 600
which will give you pageout information every 10 seconds.
Now if you have low pageout numbers or mostly zeros, then this is noise.
If you have consistant large numbers, then this is a strong indication that you could benefit from more memory.
And it my guess that with only 512MB you could use more memory, but sar will give you more concrete information to base a decision upon.

Upgrading Server Memory - Need to adjust Oracle DB Memory?

I have created a test database under Windows Server 2003 with 1GB of RAM. Now, we are planning to increase Server memory to 4GB. My question is, do I need to configure something on the Oracle DB? I am running Oracle 10G

If it is non tunable memory there is nothing much you can do..the code may consume a lot of memory....This has nothing to do with increasing the server memory
If you hit a insifficient-memory error a with pl/sql block with 1GB of memory, then you might not hit if the memory of the server in increased...
IF you want to say this as impact then i tend to agree it can impact ....Not realy flt most of the times...

If allowed, to: "BGreg" who touched upon Memory needs for "Lion" ... since mine has a mechanical maximum of (3000) even though I have physically-installed (4) does that suggest that I can't ever get "LION?"

Hi ..
Apparently, since my Imac only 'sees' 3,000 even though 4,000 Memory {physical maximum} has been installed - - it would appear that I can Never Install "LION" in ths Unit?? - - e.g. - need to remain w/ "Snow Leopard, 10.6" only, w/ all of it's updates??
Thank you!... Eli1938

More RAM or memory needed to run Windows-- AutoCAD 2010 on my mac?

Hi all,
I have researched for days and have still not been able to find an answer, last time I was here I was thoroughly impressed with the help, so I'm back!
I have a MacBook 5,1, basic model 2 Ghz, 2GB, 65.7 GB free on my hard drive. I run parallels to use Windows XP to use AutoCAD 2010. I borrowed a friends Mac, a larger "better" model and was instantly jealous at the speed his computer was able to do the same tasks my computer takes when I have Windows/AutoCAD running.
So my question is.. would more RAM help with the speed and overall function of my computer? Would more memory help? A combo of both? Also where is a reliable place to purchase what I may need? The best (and most cost effective) advice for my computer would be GREATLY appreciated!
oh, would upgrading to Snow Leopard help as well? I am currently running just Leopard as far as I can tell (10.5.8). Also would this require me to reinstall all programs on my computer?
Thanks in advance,
Laura

The short answer to your question is a resounding YES! RAM and memory are the same thing, but having more of that would most definitely improve your performance at almost everything.
Upgrading to SL may help a little, but not nearly as much as more RAM. I'm not positive, but I think that model maxes out at 4GB, so that should be your goal. If it's 8GB, even better. The more RAM you have, the better things will be with a memory hungry app like AutoCAD.

EJB and large memory - need expert advise.

Hi,
I have an application that uses alot of memory. There are many clients/session connecting to this application with persistent data.
Memory can be think of 2 parts:
- small portion which is different from one session and another, and needs to be persistent
- large portion, which is shared among clients, and change very infrequently. This is a large and complex data structure.
My problem is to avoid performance hit as much as possible. (very high client request rate).
How do I solve this problem using EJB? I am thinking either entity beans or a combination of entity and stateful session manage bean.
Swaping in and out big chunch of memory is slow. Assemble them back takes a lot of time. I may misunderstand how EJB works though. Could some of you help?
Thank you very much in advance,
VD

Is this an impossible thing to do?

Memory needed for 10.1.3.1.0 install

I'm trying to install the SOA Suite 10.1.3.1.0 so I can do a demo of the Booking application for a group of developers here.
In the installation, I'm getting an error during initialization of VM: "could not reserve enough space for object heap."
The machine is a pc with 2G of memory. I've also installed Oracle XE database and JDeveloper 10.1.3.1.0 on this pc. It also has other miscellanous Oracle products installed (eg, OWB client; AWM) but none that cannot be stopped for installation and the demo.
Can anyone tell me how much memory I'll need so the SOA installation will complete? I couldn't locate this info in the SOA Suite Quick Start Guide.
Many thanks.
Gary

Thought I'd update this thread just to put closure on it.
First, thanks to both Marc and Heidi for their help.
I ran out of time allotted to do the SOA evaluation in trying to get it installed. Even worked with Oracle tech support for a week via a Service Request. Very helpful technician, but we were unable to solve the problem. Doing an Advanced install rather than the Basic one did eliminate the VM heap space error, but other errors were raised when running the configuration assistants.
Maybe some other day.

Personalization Issue with Master Item form EBS R12 -help needed

There is an existing personalization in EBS 11i on Master Item form (INVIDITM) that is ported over to R12. Personalization prevents one responsibility from making updates/inserts.
trigger event: WHEN-NEW-FORM-INSTANCE
responsibiity: INV Inquiry
Under Action tab:
Block>MTL_SYSTEM_ITEMS>UPDATE_ALLOWED>FALSE
Block>MTL_SYSTEM_ITEMS>INSERT_ALLOWED>FALSE
Block>MTL_SYSTEM_ITEMS>DELETE_ALLOWED>FALSE (although this is not needed since seeded form prevents deletes)
In 11i this works as intended, i.e. when form is opened no updates or inserts are possible. When block is queried the data is not updatable, no inserts are possible.
In R12 (12.1.3) when form is opened no updates or inserts are possible. When block is queried the data fields become updatable and can be saved. No inserts are possible though.
I thought this is an anomaly.
Has anyone encountered this. If so what is the solution?
Thanks,
Sunil

Are thery any other personalization events in 11i, apart from WHEN-NEW-FORM-INSTANCE which are not migrated to R12?
Thanks

"Out of Memory" - need to "edit to tape"

I deleted my render files on my current sequence and am hoping that it works - but can anyone tell me if there is a fix for the "out of memory" error - It is not a capture scratch disc space issue or a ram issue... I have rebooted the computer / the app/ switched computers / saved the project to the desktop / rendered in little chunks....
if this re-render of the files doesn't work... im stumped...
any advice??
dual2.66 macpro Mac OS X (10.4.9)

Compression settings error...assume you are using the buttons on the edit to tape screen...
From the web...
“The error message can appear because the Assemble, Insert or Preview buttons refer to whatever is currently loaded into the Viewer window. If there is a Color Matte, Slug, Bars & Tone, or any generated media element currently loaded in the Viewer window, no specific compression settings are applied and Final Cut Pro cannot proceed.
If you are using these generated media elements, they need to be placed into a sequence before they will acquire their specific compression attributes. You can then load the sequence into the Viewer window and use Assemble, Edit, or Preview buttons.
It is probably simpler, however, to simply drag the Sequence icon from the Browser directly to the Assemble, Insert or Preview overlay areas on the right side of the Edit to Tape Window. This saves the additional step of initially loading the Sequence to the Viewer.”

When is more memory needed?

The article http://docs.info.apple.com/article.html?artnum=107918 is very helpful explaining the different kinds memory shown in the Activity Monitor. The article states, "If the combination of Free and Inactive is very low, then you might need more memory." I am wondering how to decide when more memory would be called for. What is the threshold at which I should consider adding more memory? Is there a per cent of total memory? Something to do with performance? Number of apps I typically run simultaneously?
Current statistics for my PB are
Total memory: 768 MB
Free memory: 114 MB
Inactive memory: 243 MB

Another way to judge if you're running out of memory is to look at the Activity Monitor's "System Memory" tab. Notice the statistic about "Page in/outs". If the second number if very large, and especially if it grows steadily while you're using your computer, you should think about adding RAM.
That number growing quickly and steadily is a sign that you're using your hard drive as RAM (the disk thrashing mentioned by another poster).

Memory needed for 1 oracle10g database instance

Hi,
Anyone know what is the minimun memory size needed for 1 x oracle10g database instance. I had a sun solaris server with 2 x oracle9i instance, will be adding 4 x oracle10g database instance. What will the memory size needed for the above....
Thank You...

I think 512M is required for a single instance.
Generally, running 4 instance on single machine is not recommended, until, unless, you have no other choice.
For EM Console, you migh required more than 1GB for installation.

Need more memory, need help

Hi There,
I tried to download some software for my Powerbook and a window opened and said not enough memory. Where do I go to buy memory? I want to buy the Apple Word Version and update to Leopard but don't know if I need to buy 2 or 4GB or MB. What do I do? Do I go to Crucial or NewEgg? My budget is kinda limited as I'm a student currently. My CPU speed is 1.33 GHz, I don't know if you need more info. Thanks in advance for your help.

Nina:
So what brand memory do I buy and where is the most reasonable & reliable place to buy from? NewEgg or Crucial?
The PowerBook G4 behaves better with optimal quality RAM. This module from Crucial is what you need.
Can I install it myself?
Yes, you can with these directions from iFixit.
And will 1GB be enough memory for Apple's Word and Leopard?
It should. When you have installed an additional ! GB module you will have a total of 1.25 GB. That should easily be sufficient.
Don't mean to bombard you with so many quest. ;)*
My pleasure.
