Is it possible to set the heap size limits in system-wide config?

Hi,
I am trying to set the JRE heap size limits (-Xms and -Xmx) by using the system-level deployment.properties file. The JRE version is 1.6 update 6.
Normally, I would have something like this in the user-level deployment.properties file:
deployment.javapi.jre.1.6.0_06.args=-Xms64M -Xmx192MHowever, when the same line is put in the system-level properties, it does not seem to have any effect. I have tried different options, also unsuccessfully:
javaplugin.vm.options=-Xms64M -Xmx192M
or
javaplugin.minHeapSize=64m
javaplugin.maxHeapSize=192mIs it not possible to address this setting via system-level properties at all? I am hoping that I will not have to resort to per-user config files.
Best regards,
Martin

Hi Michael,
thank you for your answer. I am sorry, I was unable to find the link to the message 10144001.
My ultimate goal would be setting the system level settings as opposed to settings per applet. I was unable to find any mentioning of "deployment.javapi.jre.X.X.X_XX.args" in the official documentation here: http://java.sun.com/j2se/1.5.0/docs/guide/deployment/deployment-guide/properties.html
Best regards,
Martin

Setting the heap size

Hi all,
I wanted to ask you about setting the heap size value.
How we can calculate the heap size?
I had problems with the max heap size in my application.
So I increased the max value to 2048 MB, but I am afraid that
the same error may come up again some time depending upon the
usage.
So how I can find, say for a server having 2 GB RAM,
how much heap size I should give? I read that there is no defined
formula to calculate this. But I wanted to get the best way of doing it.
Please advise,
Sandeep

As has already been said, you probably have a leak. However, when trying to gauge the maximum heap you can (not should, but can) use you have to take into account what the server is doing, and its operating system. You do not want your JVM to page. So, for a 2GB server, with no other app on it, I think the "usual" is something like 75% max? Though I really wouldn't take my word for it...it's not my field.

How to set the heap size in adminstrative console

Hi All,
Please let me know how to increase heap size in weblogic Adminstrative console.
Regards
Madhu

The answer to this depends on whether you're trying to set the heap size for a manager server which is managed by NodeManager, or the admin server.
First click on "Lock and Edit".
If the former, go into "Environment"->"Servers", then click on the server you want to configure. This should start you on the "Configuration"->"General" tab. Now click on the "Server Start" tab. Find the "Arguments" field. Assuming this is blank, put something like the following in the field value:
-Xmx1536m
Then click "Save", then "Activate Changes". When you restart the managed server the next time, it should use those new settings.
If, however, you're trying to set this on the admin server, you can't do this in the admin console at all. In that case, go into $DOMAIN_HOME/bin and edit the "setDomainEnv.{sh,cmd}" script (".sh" if on Unix/Linux, ".cmd" on Windows). Find the line that sets the "MEM_ARGS" variable, like the following on Windows:
set MEM_ARGS=-Xms256m -Xmx512m
Change this line to whatever you want, then restart the admin server.

I think the default heap size is 16MB, as for the GC output:
these [GC 2598K->2145K(2696K), 0.0035829 secs]
show the collection of Objects within the eden area of the heap (Short lived Objects),
the heap size before GC was 2598K and after GC was 2145K and the time taken was
0.0035829 secs.
These outputs:
[Full GC 2713K->2070K(4028K), 0.1933980 secs]
show the details for a full GC, these are the ones to watch out for, they will
take longer and the JVM (no mater how many processors) will block during a full
GC....I.E no server response at all.
The smaller the heap size the more often a full GC will occur, however the larger
the heap, the longer the full GC will take.
One of the new options for jdk 1.3.1 is the -Xincgc option, this will do incremental
Garbage Collection, overall it will take longer than normal, but the individual
Full GCs will take less time....so the server is not hung for as long at any one
time.
Set -Xms (the minimum heap) to the same as -Xmx (max heap), this increases performance
as the JVM does not have to repeatedly assign more memory to the heap.

How to set the page size and the margins programatically

Hello,
I am working with crystal report XI Release2 and asp.net.
One of my report is having 4 graphs in a single report.In order to display all the graphs in one page i have set the paper size as A3.(Via Crysta report ->File->Page set up)
But the page size A3 is not provided by all printers.So problem comes when the application is diployed on a machine which does not support A3 Printer.All the graphs will not be shown on a single page.
Also Each and Every time ,when the application is diployed on a machine,user has to open the crystal report and adjust the page size accordingly to get all the reports on a single page.
This is a kind of usability issue also.
Is it possible to set the page size and the margins programatically say for eg 11 X 17.so that with out doing anything all the 4 graphs will get displayed on a single page ?
Please let me know if you require more information regarding this issue.
Thanks in advance.

Hi Ludek,
i could solve the issue by using the follwing code.
report = new ReportDocument();
PageMargins customPageMargin = report.PrintOptions.PageMargins;
report.PrintOptions.PaperOrientation = PaperOrientation.Portrait;
report.PrintOptions.PaperSize = PaperSize.Paper10x14;
customPageMargin.rightMargin = 1;
customPageMargin.topMargin = 0;
customPageMargin.bottomMargin = 0;
report.PrintOptions.ApplyPageMargins(customPageMargin);
Thanks for you help.

Good afternoon,
This works: f?p=1:#MYPAGENUMBERCOLUMN#::Session:Request:Debug:Clearcache:itemname:itemvalue:printerfreindly
It works very well. I have been struggling for a couple of hours trying to figure out how to calculate the page number I wanted to link to from a report column defined as a linked item. I ended up modifying my VIEW to include the page number for that particular type of data and use this technique to jump to the correct page.
Thanks for posting this. Nothing else seems to work.

How to set max-heap-size outside the jnlp file?

Due to bug_id=6631056 It may not be possible to specify max-heap-size within
the JNLP file for certain jnlp java applications.
Are there other possibilities to specify this Jvm parameter?
In the ControlPanel there is the possibility to specify Xmx for applets but not for jnlp.
I have tried to add properties like
"deployment.javaws.jre.0.args=Xmx\=128M" without success
Many thanks

Even in JNLP also you can specify the max heap size
<j2se version="1.5+" initial-heap-size="128m" max-heap-size="512m"/>
Thanks,

Plz can you help me. How to increase the Heap Size!!!!!!!!!!!

Hi,
i'm new to 10g appl server
Failed to deploy web application "AGXI51". Failed to deploy web application "AGXI51". . The evaluate phase failed. The Adapter used in the evaluate may have thrown an exception.
Resolution:
Please call Oracle support.
Base Exception:
java.lang.OutOfMemoryError
null. java.lang.OutOfMemoryError
i'm getting this Error while deploying the application.So wat is the procedure to increase the Heap Size
Regards,
Niranjan.D

Locate opmn.xml on your instance. In file locate section relevant for container you use (i.e. "home"). In next line you can see tags where startup parameters are set. You should add following parameters (this will set heap size on 512Mb)
-Xms512m -Xmx512m
For detailed explanation I would recommend you to check following link:
http://download-uk.oracle.com/docs/cd/B25221_03/web.1013/b14431/troublesht.htm
Hope this help.

Upto how much I can set maximum Heap size for jvm?

I am running application on 8GB RAM Windows 64 bits machine.
I am running out of OutOfMemory (Heap Space). I want to increase the Heap Size for my jvm.
But can anybody please tell me what is the limit by which I can set the maximum size for heap?
Thanks in Advance,
Jenish

Max allowed memory per process is 2 raised to the 64th power. What maximum memory you can set depends on the memory available
for your application. You may be able to set more than 8GB ram then it will use the swap space and it will slow down your application
performance. So try different memory size and see which one works best for your application.

How to increase the heap size of the container in whioch BPEL is running ?

Hi All,
I recently raised an SR they have asked me to do the following,
Can you please try and start the container running the BPEL process with max
heap space (-Xmx) of 2 GB and the eden space (-Xmn) at about 60% of 1228m and
the option -XX:+AggressiveHeap set. (even though this option is recommended for
multi processor machines say 4)
can anyone kindly explain me how to increase the Heap size and Eden size of BPEL container ?
Thank You

Hi Deepak I cant see any attribute or element in the oc4j_opmn.xml file regarding heap memory. In the server properties I changed the size of heap memeory how can I rollback.

Need help setting the exact size of my JSlider

Hello everyone. I'm trying to build a small program to help people learn a about RGB colour values, and at the same time teach myself a bit more about Java. Things have been going fine so far until I came to setting my JSlider's size. The intention is to have three JSliders with a JPanel next to each. The I need the track of the slider to be exactly 256 pixels tall (one pixel per gradient value painted into the adjacent JPanel) plus whatever extra padding and spacing the Look And Feel dictates.
I've got the height set to 256 pixels in the following code, but it makes the JSlider as a whole 256 pixels tall and so squishes the track. I've set the minor tick spacing to 2 so that if the track was actually 256 pixels tall, the ticks would alternate over each screen pixel. If you compile and run the code, you will notice that a few ticks appear next to each other without a one-pixel gap between them. I've also verified it by taking a screen capture, pasting it into the GIMP and then using the measure tool to check the size.
I've tried searching through the API documentation to find ways of doing it, or to see if some ideas I've had so far were possible, but so far, I've not found anything particulairly satisfactory. I even tried to see if I could set the JSlider size to current JSlider size minus the track size, plus 256, but I couldn't find a way of getting the current size of the track.
Can anyone help me out here? I'm rather stuck.

Here's the code with all but the JSliders stripped out. Sorry about having to put it in a seperate post; the forum wouldn't allow it.
Here's the code I have so far:

Is it possible to set the heap size limits in system-wide config?
