How to adject ABAP HEAP SIZE???

Hi,
How do I adjust ABAP Heap size..??
any step by step or note?
Thanks,

Hi Afi,
you can get some information here:
http://help.sap.com/saphelp_nw04s/helpdata/en/7a/caa6f3bfdb11d188b30000e83539c3/frameset.htm
There you will also find the parameters:
abap/heap_area_dia: Heap Memory Limit for Dialog Work Processes
abap/heap_area_nondia: Heap Memory Limit for Non-Dialog Work
abap/heap_area_total: Total Quota for Heap Memory
and recommendations how to configure them.
Have a look and award points if useful.

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.

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.

How to increase JVM Heap Size

Hi all,
Our Environment
===============
OS - Windows XP Service Pack 3
Oracle Developer Suite - 10.1.2.3.0
Oracle Forms & Reports Service 10.1.2.3.0
Oracle Database 10.2.0.1.0
JDK 1.5
Jinitiator 1.3.1.30
Apache POI 3.5
From forms we are writing to excel files after copying XL template using Apache POI 3.5 and JDK 1.5. This XL template file has got lot of macros.
We have imported the Java class files into form as pl/sql library. We are able to write upto 7Mb size of XL file. Beyond that size it comes with the error Ora-105101.
We tried to increase the JVM Heap Size to 640M by setting values -Xmx640M everywhere in OC4J_BI_FORMS/Server Properties/Java Options, Home/Server Properties/Java Options through Enterprise Manager console. Also manually set the values in OPMN.XML and reloaded the same. Also set -Xmx640M in Jinitiator 1.3.1.30 Java Runtime Parameters. Also set in Java console. All settings have no effect.
We have written a small program to display the run time memory from forms, which displays only maximum memory 63M all the time.

From command prompt if we run the same java class file by passing -Xmx256m parameter we are able to write to big XL file.
Can anyone tell me where I am wrong... Can we increase the JVM Heap Size from forms...

I have a simular problem.
Via Forms I call a Java class (import Java class -> PL/SQL class java method).
For this specific process I need to set the Xmx java option...
How do I do this ?
Changing the java option for the Forms-OC4J in the EM doesn't help.
Is there an other level where I can modify this ?
Does the java process of the forms is the single process that exists ? How does he handles such java calls?
Are that separed java processes ? threads ? ....
Thanks !!!

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:

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,

How to Increase Java Heap Size through Java Code. Increase inside Code?

Hi All,
I am using a third party tool. When i run a particular program it says OutOfMemory error. I like to increase heap size through Java Code before calling the particular Java application or Code..
Is there is any way to set the Heap Size through Java Code in run time ???
Pls Kindly help.
Thanks.

if you start the program with a -Xmx512m flag, the virtual machine gets half a gigabyte of memory to use (or that's the max it's allowed to use). All things run in the same virtual machine will have the same limit, third party tools run in the same virtual machine can't "not care about this" unless they're throwing OOMs themselves for some stupid reason.

How to increase the Java Heap size ?

Hi
I am new to java. I have created a java application and i configured in Eclipse. While running my application it throws an error that
"Exception in thread "Thread-21" java.lang.OutOfMemoryError: Java heap space"
i have used threads in my application. Then i searched some forums regarding this. The answer i got is "Increase the java heap size" using
"java -Xms64m -Xmx256m prog" in command prompt. while running.
But i am not running my application in command prompt. I used Eclipse to run my application. Here my ultimate question is how to set the heap size while running the application in Eclipse and where to set in Eclipse.
Kindly help me.

where is this limitation coming from. How to set the heap size to 6g.

You need to use the -d64 switch to request the 64-bit JVM. E.g.,$ java -showversion -Xmx6g HelloWorld
Invalid maximum heap size: -Xmx6g
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.

Heap Size in 64 bit operating systems

Hi,
I have written a Java application which needs huge size heap. I tried to run the application under 32 bit windows operating system, but with 32 bit OS I got maximum heap size of 1.5 GB. To get more heap I have installed Windows 2003 Standard edition 64 bit version. Also I have installed JDK 1.7 64 bit for windows. I am using Netbeans IDE 6.7. I have configured Netbeans for 64 bit JVM. With this configuration I tried to set heap size of 1.6 GB it gives error "Could not create Java Virtual machine......". Also If I check proceess in task manager I see java.exe * 32 process. Does this mean JVM being used is still 32 bit JVM?
Please let me know how to get more heap size under 64 bit OS?
Regards,
-Suresh Shirgave

From a cmd window run a simple program using a 64-bit jvm (HelloWorld or similar) with different -Xmx values to establish the limit at which the program will run.
<pathTo64-bitJVM>java -Xmxnn HelloWorldIf that's different from NB, then it's a setting of some kind in NB. Maybe you are pointing NB to a 32-bit JDK? Check the value in <NBInstallDirectory>\etc\netbeans.conf. If that's not it, check NB Help. You might want to ask the question at a NB forum, since this is a new version there may be a problem. Note that these forums are for Java language topics.

Setting Heap Size from JAR

Hi,
Does anybody know here how to specify the Heap size with JAR.
From command line, I type java -jar -ms128M -mx350M IzoneIDE.jar
My jar file is executable, so how can I specify the heap size in Jar Files.
Please dont comment this as a Cross Post as I dont find any answer in Java Programming forum, thats why I post it here.
Thanks
