How to decrease memory usage in XE 11.2

Yesterday I uninstalled Oracle XE 10 and installed OracleXE 11. Everything is going fine so far except for the memory usage - it's around 800 megs. I remember having this problem with the last XE instance, and there was some way to change this, but I don't recall what it was. I looked around on the XE web interface - which is very different from the last interface - but couldn't find anything.
Does anybody know what I'm needing to change?
Thanks in advance!

How to minimize memory usage with VM settings

Using JDK 1.4.2, I am trying to minimize the memory usage of my application.
Our GUI application consumes about ~20MB of heap space during normal operation, but it can easily grow to 50MB in some rare cases (Special feature accessed by user).
We have to be able to run multiple instances (separate process/VMs) of this application on low end Windows PCs.
The applications don't usually run for very long (less than 8 hours).
Here is my problem.
If I set the -Xms=20M -Xmx=64M, it works fine, but the GC is not very aggressive and soon, the application starts using a lot of memory, even if it is not really needed. And it never returns the memory to Windows OS.
So each VM take more memory than really needed, which causes significant swapping on these low end PC (little RAM available).
If I reduce the -Xmx flag, than I run out of memory in the rare cases where I need the full memory.
Ideally, I would like to configure the GC to be more aggressive, i.e. the GC should collect instead of getting additional memory from the OS when possible.
I read a few papers on Sun's web site about HotSpot tunning, but most of them are geared for large servers.
Thanks!

And you are using the task manager to determine how "much" memory is being used correct?
I suggest that you search out and read the numerous threads on this site that discuss that subject.

How to determine memory usage?

Is there something built into OSX that permits me to monitor and/or log memory usage?
I use Logic Pro and FCP and would like to know if I reaching the limits of my memory (4GB) with the type of work I do.
Thanks, Rob.

How to check memory usage of a debug

I am very new, sorry for any newbishness on my part.
Is there a way to track how much memory your debug is using? I am trying to make a game, and I have 2 ways of doing something.
One with an array of square objects doing hitTest, and one only 1 object and an array of cords doing a nested if{}.
I want to see what each of these are doing in terms of memory usage during runtime and which one would be better.
(added)
Specificly not just which one of these is better, but also as different things are applied, I want to test how each of these things responds and which one would slow down a computer less. And later on as things progress I want a way to test it.

How to reduce memory usage when loading bitmaps from the library?

When I use BitmapData.loadBitmap() to load an image from the library and then attachBitmap() to add it to a MovieClip it takes a lot more memory as opposed to just having the same image inside a MovieClip statically in a frame on it's timeline.
The function dispose() not only clears the BitmapData object but also destroys the previously attached bitmap inside the MovieClip, so it can not be used to free any memory.
Is it how it is supposed to be or is there any other way to dynamically attach bitmaps with memory usage comparable to just having them on stage?

no, you use attachMovie() to create instance from library movieclips that have a linkage id.
you can then create a bitmapdata instance and use the draw() method to overlay as many as needed.

How to monitor memory usage of "Memory-based Snapshot" executable (MRCNSP) in Linux?

We have noticed in the past that MRCNSP/Memory-based Snapshot program executable consumes around 3.8 GB of memory on the linux VM. I understand that value change planning is 32 bit executable so 4 GB is the limit. I want to monitor the memory usage of the executable when the program runs. The program usually runs overnight. I wanted to check with you experts if you have any MRP executable memory usage monitoring script that I could use.
I found the metalink note OS Environment and Compile Settings for Value Chain and MRP/Supply Chain Planning Applications (Doc ID 1085614.1) which talks about "top -d60 >>$HOME/top.txt". Please share your ideas for monitoring this process.
We do not use Demand Planning or Demanta or Advanced Supply Chain Planning which are 64 bit application. That is our future direction.
Environment:
EBS : R12.1.2 on Linux. The concurrent manager is on 64 bit linux VM, web services on 32 bit VMs.
DB: Oracle DB 11.2.0.3 on HP UX Itanium 11.31. Single database instance.

RAM on the controller is not the same as the C: drive. With respect to the controller, you can think of it in the same terms as your computer. RAM is volatile memory and your C: drive is non volatile flash memory.
Depending on the frequency of the temperature excursions above and below your 70C threshold, the service life of the controller and the method you used to append to the file, there could be a number of issues that may creep up over time.
The first, and the one you brought up is the size of the file over time. Left unchecked this file could grow continuously until the system literally runs out of flash memory space and chokes. Depending on how your are appending data to this file, you could also use more than a trivial slice of processor time to read and write this big file on disk. While I have not personally ever run one of the RT controllers out of "disk space", I can't imagine that any good could come of that.
One thought is to keep a rolling history of say the last 3 months. Each month, start a new file and append your data to it during the course of the month. Each time a new file is created, delete the data file from something like 3 months ago. This will ensure that you will always have the last 3 months of history on the system, however the monthly deletion of the oldest data file will limit you to say 3 files at whatever size they happen to be. Unless there are hundreds of thousands of transitions above and below your threshold this should keep you in good shape.
I also eluded to the method you use to write to this file. I would ensure that you are appending data using the actual file functions and not first reading in the file, appending your data as a string then writing the entire file contents back to disk. In addition to causing the highest load on the file system this method also has the largest system RAM requirements.

How to calculate memory usage base on graphic utilization

Dear All ,
We have t2000 server with solaris 10 and 15 zones inside , and install SMC server include module ,Harddware configuration is 16 Gb Memory , 4 x 72 gb Hardisk and Swap 4Gb .,from menu Manage container manager , we select host of the server then click utilization , but i see memory usage 19759 Mb , How to calculate memory from this graph ? cause maximum ream RAM only 16 Gb in our server.
Regards
Hadi

PL/SQL collections are stored in the PGA. So you can monitor the PGA utilization of the session(s) to see how much PGA they use.
SELECT sid, name, value
FROM v$statname name
JOIN v$sesstat using (statistic#)
WHERE name.name in ('session pga memory', 'session pga memory max' )That will show you, for each session, the current PGA consumed by the session and the high water mark of PGA consumption by that session. You can join to V$SESSION and add additional predicates to narrow things down to the particular sessions you are interested in.

How to reduce memory usage?

OK - I've read through a ton of posts that discuss the "Out of memory" problem in Encore, but what can I do to reduce memory usage?
I'm trying to produce a very simple Blu-Ray (h.264) project in Encore CS3 on Windows Vista. There are 8 or 9 timelines, a main menu, and 6 sub-menus. Each sub-menu has six static buttons. There are no transitons or motion menus. When I load the project, Task Manager says Encore is using about 1.3 GB RAM. I constantly get "out of memory" errors.
I've loaded the same project on Vista 32-bit w/ 4GB RAM and Vista 64-bit w/ 8 GB RAM. Same behavior on both.
Two questions:
1. Why does Encore need 1.3 GB RAM for such a simple project?
2. How do I reduce the memory usage?
TIA for help on the PITA,

T520 - How to decrease memory frequency

Hello everyone,
I am lucky owner of T520 with Intel 2620M processor and 4Gb of memory onboard.
One day I bought memory kit Kingston "Hyper X" KHX1600C9S3P1K2/8G (2*4Gb) and thought "memory supports 1600 and 1333Mhz, and my laptop needs 1333, so it will select correct frequency automatically".
But there started problems - processor initiated new memory with frequency 1600Mhz, and all the system now works unstable. I have errors in Windows 7 memory test. By the way, I tried to check memory pieces apart each other, and in single mode they work fine. SO I think that processor's memory controller is loaded too much in 'dual channel'
So my question is - how can I decrease memory frequency on Lenovo T520 laptop? I was confused, but in BIOS there is no option to change frequencies like it is on Desktop PC...
Thanks.

Preload - how to see memory usage?

excuse me for revitalizing this, but this:
lucke wrote:Set PRELOAD_OPTS to verbose 10.
still is neccesary to get an output in the log.
btw. my log doesn't inform the memory-usage.
is there an easy way to see how much memory it actually uses?
Shouldn't there be a proccess running wich I can see in htop and therefor the memory usage?

How to meter memory usage

Hi,
I want to meter the memory usage of some XML-Parsers. Thus I do something like
long before = Runtime.getRuntime().freeMemory();
//parse
long after = Runtime.getRuntime().freeMemrory();but always the difference (after - before) returns a negative value, which means that the parsing creates memory ;-)
First I guessed, that during parsing the GC gets active and collects more objects than created. So I called the GC right before the upper code, wait for 2000ms to ensure the GC does something, but the result is the same.
I tried this with the kXML2.0, XParse-J and ASXMLP with different sizes but the same result.
What goes wrong there?
Kay

Where are you trying it out?
Some phones, specially high-end phones like Series 60, allocate more heap memory dynamically while the program is running, so the freeMemory() keeps getting bigger the more memory you allocate.
Other than that, there really is no way to make sure the garbage collector runs after you call System.gc(). Implementations are free to completely ignore a call like this, even if you give them time to do it.

How to Maximize Memory usage for JDK 6 on Solaris 10.

Hi there,
I deployed jdk 6 & Tomcat 6 running on Solaris 10 with 8GB of RAM Sun Fire x64 x4100 M2 m/c.
Its relatively fast. However, the java could allowed me to set the Max Java OPT to only 3GB. I don't understand and there isn't any extra applications. All are prior Solaris 10.
Java will not be able to start if I set more than -J-Xmx3072m.
Appreciate your advise and expertise.

Hello Neville:
I seem to be coming off as negative - not my usual approach. However.......
I am a retired webmaster and don't have Lion but I am impressed by your tip. Well written and researched. I think we should all do our bit to educate and encourage others to open applications and use the Terminal.
a different point of view from someone who has been posting in these forums for many years.
Almost all of the people who seek help here are not:
1. Retired webmasters.
2. Know anything about the arcane terminal commands and, more importantly, how much damage they can cause their system by a missing space or character. Apple has spent a lot of time to develop OS X to a point where people do not need to learn about or understand Unix-like command language.
I salute people who are technical enough to use terminal commands. It is, however, IMHO, a real disservice to suggest to non-tecchie people that it is ever necessary (or desirable) to operate at that level.
Having said all that, I respect your comment and point of view. I would reiterate, however, that solving non-existent problems is a waste of time. By non-existent, I mean that if there are no performance problems, it is irrelevant how much memory a program uses. My current base-level iMac has 4 GB of memory and a Terabyte of HD space.

How to monitor memory usage in a cRIO controller?

I have an application where I suspect the customer is operating in a hotter environment than they are claiming. I prepared the RT host vi to log a simple text file directly on to the RT's C: drive. In this case I'm only logging the transition of events when the chassis temperature exceeds 70C and then becomes less than 60C along with a date and time stamp. (It's not continually logging data.) However, I'm concerned that over time (i.e months from now after I've long forgotten the project) the file will get overly large and affect system operation. There are articles that deal with memory management but I'm not sure how to interpret them. They talk about RAM. Is RAM the same as the C: drive on the controller? How do I determine the available memory on the C: drive; like using "dir" in the old DOS days? What is the best Knowledge Base article that deals with this issue. This system is a stand alone application. (The host PC is not normally connected.) I am using a cRIO-9012 controller and LV v.8.6.

Large image sequences in Flash - How to reduce memory usage?

So I'm trying to publish a looping animation in Flash with a large amount of image sequences in it. (around 3000 frames all told). And I'm having problems with the swf using too much memory when it's played.
The swf is about 80mb, but the file uses an excess of 2gb of ram when played. I don't know why that would be. A memory leak?
My understanding is: that Flash will just load all images in a swf into memory unless you dump the memory somehow.Can anyone explain how to do this? Is it possible? I can't seem to find a solution online.
Thanks

Thanks for your reply. I think I was being just overly ambitious trying to get this to play in swf form on sub 4gb ram machines. I've resorted to external video.
