Java Heap Size Recommendation Request
Looking for suggestions on tuning. Running CF10 update 13 on a 64 bit server with 8 GB RAM, running into memory issues (I suspect). JVM is only set to 256 / 512 right now, so I'm going to increase it. CF and a handful of sites is pretty much all this server does.
Suggestions on what I should set this to now? We seem to be under 50% memory usage at the present time (right now 3.44GB), and CPU is 0-2%.
Carl,
Thank you! I appreciate your answer very much, with reasoning and a holistic view.
I will look into Java monitoring. Have not done that yet, but always looking to upgrade my skills.
I can set JVM in CF Admin and have done so. I know there are some things you can do to activate the jvm config file but I haven't had the need to mess with that yet. Thought I changed it once, but it was reset when I restarted CF so swing and a miss.
Systems running better already though with that huge headroom in memory.
Thanks again!

How to increase Memory and Java Heap Size for Content Server
Hi,
My content server is processing requests very slowly. Over performance is not good. I have 2 GB of RAM any idea what files I can modify to increase the Java Heap Size for the Content Server. If I increase the RAM to 4 or 6 GB where do I need to make changes for the Java Heap Size and what are the recommended values. I just have Content Server Running on the linux box. Or how do I assign more memory to the user that owns the content server install.
ThanksYou might find these interesting:

Please let us know if there is any other parameter which can be used to
fine tune this and get this up and running,
Thanks for the help.Raviraj,
Are you working with Boopaln? The reason why I as He posted the same error (in the same complex table) With the same changes but just a different user shown.

I am getting the below error while deploying some soa applications in WLS 10.3 on solaris platform.As a workaround,
the server instance has to be restarted everytime i make the deployments when i face this OOM situations.
usually i face this issue after first deployment onwards.
So, everytime i make the next deployment the server instance has to be restarted before that.
The server is configured with 1Gb JVM and runs on JRockit jrrt-4.0.0-1.6.0.

Thanks,
BoopalanLooks like ur getting heap size error while trying to fetch records for ctparts complex table. From platform point of view you have increased heap size. Next step is to analyze application settings for ctparts complex table. As indicated by Steve from application point you need check the need for amount of materials your trying to retrive , can you set filter for ctparts , does ctparts BAPI execute in SAP without any timeout error.
What is the version of Work Manager your using ? With WM 6.1 you have options to take advantage of data staging that is delievered as part of standard application.
Thanks

You should run your JAVA AS with the recommended settings described in the note
"Java VM settings for J2EE 6.30/6.40/7.0"
SAP Note Number: 723909.
If you do so, you can find the garbage collector log messages in your dev_server* or your std_server*.out file.
You can also use the option -Xloggc:<file> to log to a seperate file.
You can visualize the GC log file with a tool like GCViewer.
See
http://www.javaperformancetuning.com/tools/gcviewer/index.shtml
for an overview of this tool.

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.

8.2 EPPM Application Server Java Heap Size
Hello I am reading the sizing guide is there a way to calculate the Java Heap Size required? The guide suggest 8GB was wondering if anyone has any experience and how much java heap size are you using?
JVM configuration is largely based on the load on the server. You can start with as little as 2GB and based on the load, you can increase it. Other factors that you need to consider is the number of CPU, RAM, Swap space etc.
Sachin Gupta -
Gurus,
Could some body help me to understand the differentiate between heap size parameters -Xms and -Xmx ? I usually change both of them. One another is that, the maximum heap size we can use is total ram/2 ?
Thanks,Text from the above link
==================
As part of the Best Practices, we know that we should be setting -Xms & -Xmx Java command line parameters. What are these settings and why is it required to set these.
As JAVA starts, it creates within the systems memory a Java Virtual Machine (JVM). JVM is where the complete processing of any Java program takes place. All JAVA applications (including IQv6) by default allocates & reserves up to 64 MB of memory resource pool from the system on which it is running.
The Xms is the initial / minimum Java memory (heap) size within the JVM. Setting the initial memory (heap) size higher can help in a couple of ways. First, it will allow garbage collection (GC) to work less which is more efficient. The higher initial memory value will cause the size of the memory (heap) not to have to grow as fast as a lower initial memory (heap) size, thereby saving the overhead of the Java VM asking the OS for more memory.
The Xmx is the maximum Java memory (heap) size within the Java Virtual Memory (JVM). As the JVM gets closer to fully utilizing the initial memory, it checks the Xmx settings to find out if it can draw more memory from the system resources. If can, it does so. For the JVM to allocate contiguous memory to itself is a very expensive operation. So as the JVM gets closer to the initial memory, the JVM will use aggressive garbage collection (to clean the memory and if possible avoid memory allocation), increasing the load on the system.
If JVM is in need of memory beyond the value set in Xmx, the JVM will not be able to draw more memory from system resource (even if available) and run out of memory. Hence, the -Xms and -Xmx memory parameters should be increased depending upon the demand estimation of the system. Ideally both same should be the same value (set at maximum possible as per demand estimation). This ensure that the maximum memory is allocated right at the start-up eliminating the need for extra memory allocation during program execution. We recommend aggressive maximum memory (heap) size of between 1/2 and 3/4 of physical memory.

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.

Jean marchello,
thanks for your answers.
i install oracle bi publisher in standalone on windows 2008 64 bits.
the installation create a weblogic server with an adminserver, bi publisher is installed in the adminserver.
if i look for setDomainEnv.cmd,
i have
set XMS_SUN_64BIT=256
set XMS_SUN_32BIT=256
set XMX_SUN_64BIT=512
set XMX_SUN_32BIT=512
set XMS_JROCKIT_64BIT=256
set XMS_JROCKIT_32BIT=256
set XMX_JROCKIT_64BIT=512
set XMX_JROCKIT_32BIT=512
so , i use java sun 64 bits , so the setting XMX_SUN_64BIT=512 is used.
but if i look in the task manager, the java.exe process, the memory allocated is around 2G .
i don't find xmx settings in adminserver.log located at
I:\BI_HOME\BI11G2\user_projects\domains\bifoundation_domain\servers\AdminServer\logs

Iseries Settings for JAVA (Heap sizes)
I am new to SAP, not to Iseries. The notes 717376 and 990892 give me insight as to what needs chging but not the how to change it.
I want to know if I can set the heap sizes directly in the IFS and How. Our consultants are not ISeries strong... I can not get the Config tool to work, and Visual Admin is too
foreign for me to find where the sizing is.
PI takes way to long to start up and my guess is we need initial heapsize to be set and max increased.
thank youHi
I am not sure about iSeries but the configuration of parameters in SAP Java stack always affect the Java system performance. The few steps to change parameters are as follows:
Main point is you have to use the configtool only. You cannot use Visual Administrator to change the memory parameters.
Open the ConfigTool ( usr/sap/<SID>/DVEBMGS<sys nr>/j2ee/configtool file would be configtool.sh)
Then at the left hand pane you would get the Server and Instances (local and global : these are used for the cluster environment; local means that you are logged into the current instance....global means that you want to change the settings for whole of the Java stack)
If you click on them like Instance_<instance number>; right hand side you would get all the parameters where you can change these settings.
Follow the notes instructions.
It would ask for the restart of the SAP server
