-Xms -Xmx / Problem increasing plugin memory

A very interesting problem..
On a Win2000 Professional m/c with plugin versions 1.3.*,1.4.*, IE 5.5
I am trying to extend the memory 768M to 1G by doing
-Xms768M -Xmx1024M
I tried different combinations of max and min heap size.
Anything more than a 256M makes the browser crash. Sometimes that happens even for 256M.
Any idea??
I would greatly appreciate any inputs.
Thanks
aabr.

I have been having this same problem with an application we deploy for about 2 years! I've never been able to find out what exactly the problem is... Now, we are moving to WebStart, I thought getting away from IE would be a good way to get away from this problem, but WebStart also crashes when using "certain" values for -Xms and -Xmx
What do we do now, I know there must be lots of people with this problem. I'll open a new POST on the WebStart forum, since it happens on it also.
I really want to get this problem fixed.

Set Xms/Xmx based on Jconsole memory monitoring

I used jconsole to monitor memory usage of a java server program running with JDK 1.5.0.3 in Linux, in order to set the Xms/Xmx option for the program. I found that memory usage of the process is no more than 4MB. But somehow after setting the Xms/Xmx to be 4MB, the server program could not run (its client programs could not connect to it). So I tuned the Xms/Xmx value and when I raised them to 512MB, then the server worked again.
I don't understand why this happens. Is Jconsole reading not a good reflection of the heap memory usage? Or something else might be wrong?
Thanks for any idea on this.

Hi,
We are using weblogic 8.1 sp3 with the jdk1.4.2_05 (we do not use jrocket) for the implementation of some of our solutions.
We are trying to optimize performance generally on servers with 2 processors and 4-8Gb of RAM, and some exceptions such as forinstance a test-machine we have at the moment with 4 processors and 20 Gb of RAM.
>
Although we seem to be able to improve performance by raising the settings for Xms and Xmx to 1024m ( even though our developmenttests done in the labs in Cary, NC - USA have resulted in recommendations that show lower values ) we would like to have some more
info because not all info we have points to the same directions. For instance
1. What are theoretically the maximum values for these settings (in particular Xms and Xmx)?Theoretically the maximum is a memory space addressable by a process.
2. Should Xms and Xmx be set to the same value (as mentioned in info from your website - see below), or are there situations wheredifferent values could improve performance ?
For a production environment Xms and Xmx should be equal so that JVM doesn't
spend time shrinking and expanding heap.
3. Is there other general advice you can give for improving performance using these settings ?Generally it is a good idea to keep heap under 1G. Bigger heap means longer GC-s.
You may consider co-locating cluster nodes running in separate JVMs if you have
enough CPUs and extensive RAM. Generally 2 CPUs per weblogic instance is enough.

How to increase JVM memory for Web Logic 10.3.3 - OSB 11g

Hello folks,
I am running OSB 11g on WebLogic 10.3.3 to call some services passing large XMLs requests. These XMLs are something around 10mb each. Unfortunately, I got errors regarding memory.
I am using Eclipse with OSB plugin to develop, and I have configured the weblogic server to start up it from the eclipse, thus I don't need to start up through command line.
I would like to know where I can change the memory arguments to start up the JVM which runs the WebLogic server. As I am starting up the server from eclipse, I can't change the memory size args from command line.
Is there a file where those arguments are stored? or some configuration on WebLogic console which I can increase the Xms and Xmx ?
The JVM is jrockit_160_17_R28.0.0-679
This is the eclipse console output when the server is starting up:
JAVA Memory arguments: -Xms256m -Xmx512m

Hi Davinod,
Yes, the correct place is to change the memory arguments in the "setDomainEnv.cmd", however can you confirm if the changed memory arguments were reflected in the logs or not.
If yes then you need to try to increase the memory arguments again and test which is the best working memory argument suitable for your environment, this would take some trials.
However if the memory arguments are still not reflected then try to set it properly as shown below:
set MEM_ARGS=-Xms1024m -Xmx1024m

Java Heap Sizes -Xms -Xmx

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.

10.10.1 I use sysctl.conf to increased shared memory. 10.10.1 does not read sysctl.conf anymore

I need to increase shared memory. In 10.10 is use /etc/sysctl.conf with a line kern.sysv.shmmax=16777216 and this works. Also in 10.9. But in 10.10.1 shared memory can no longer be increased from the default 4194304 by this means.
The question is simple: how in 10.10.1 does one increase kern.sysv.shmmax in a way that survives a re-boot

I have the same problem on my windows 2003 server but the
thing is that I have not been able to get the same error on any
other machine including a windows 2003 I installed on VMWare on the
same machine. I have narrowed down to where in the encoder this
happens. The encoder uses page file backed file maps to register
session information. The call to MapViewOfFileEx method of the
Win32 API fails with the "access denied" error. Whatever it is,
it's due to some defect in the Windows installation I have because
I do not get that message on any other windows installation even
the ones I do with the same windows CD !
I am still trying to find out what the defect might be but I
thought you should know it's got nothing to do with you Windows
make and model...it happens for me on 2k3 and for you on XP...so
you should looke elsewhere..

Increasing Heap Memory

How do I do to increase the memory available to the JVM? I have an AVLTree class that I am trying to test how many nodes can hold, but even though I have tried on PCs ranging from 128MB to 2GB of RAM, the results is always the same: + - 2.3 million nodes. I have used -x option to increase heap size but that does not seem to work.

Hi,
I encounter the same problem with using 1G RAM & JRE 1.5 & running applet in IE.
The IE memory usage always run on maximum 139000K. Even I tried "java -Xms64m -Xmx512m" & "java -Xms256m -Xmx768m", the memory usage still in 139000K, and Java console shows "Exception in thread 'AWT-EventQueue-2' java.lang.OutOfMemoryError: Java heap space". How can I solve it?
Thanks.

Increasing Available Memory

Is it possible to increase available memory in Appleworks so it can open larger files, such as templates?

Welcome to Apple Discussions, Doug!
OS X manages memory for you, there is no way to change the memory setting on your own. Adding memory to your machine, or closing some other programs while you are running AW will give the OS more to work with. How much memory do you have? What problems are you having when opening templates?

How to increase the memory for my weblogic server in Jdeveloper 12.1.2.0.0 ?

Hey everyone,
So as my title says, i'm trying to increase the memory for my weblogic server in my windows 7 64 bit machine, with 8GB ram.
The values appear to be: JAVA Memory arguments: -Xms256m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=512m
I've done some search from this forum and i've added this to my jdev.conf:
AddVMOption -XX:MaxPermSize=1536M (in this one i've only changed the value)
AddVMOption -Xmx1536M
AddVMOption -Xms1536M
And i've changed this: MEM_ARGS="-Xms1024m -Xmx1024m" in my startNodeManager.sh file
I'm still getting the same line in my server but i need to change the values since i'm not getting the server to run my application very well (it gets stucked in loading my databases and graphs) and i think it will continue untill i get a heap exception error.
Any ideas of how to change this?
Regards,
Frederico.

Thanks Alejandro .
I'm going to ask you another question and this one is quite important.
Whenever i run my project a couple of times, i'm not able to retrieve the page, it just gets stuck on loading.
It just stops the loading, like its a really really slow page. I'm not using a lot of rows in my database so i don't take to much memory but it doesn't load and i know everything is fine but i just added some graphs after testing it.
Do you know why?
In the console it says that everything is fine and shows the link for the page but it never loads completely until it gives a error because it does not respond in 600 seconds.
Strange right?

Is there a way of Apple increasing my memory and processors?

Is there a way of Apple increasing my memory and processors so that my 2010 MacBook will run faster? I use 3D programs and filmmaking editing software, and my laptop, as awesome as it is, can't quite keep up with what I do. The programs I am using:
Blender (Open source 3D software)
Final Cut Express
iMovie '09 (usually editing off an external hard drive)
I make most of my films in HD too.
I heard that you can manually replace the RAM and stuff, but Im not too keen on it. Being me, I might brake something. But does anyone know of a safe and secure place to buy extra RAM and memory and processors for a 2010 MacBook.

The only way to upgrade processors is to buy a new Mac. In your case a MacBook Pro would be more appropriate for the tasks you're undertaking.
Your MacBook will only take a maximum of 4GB RAM.
In addition to etresoft's recommendation, Crucial Memory is reliable and equally good service. I think this is the RAM for your model, but to be on the safe side, use the "scan my system" option to getthe exact match.

Problem in ABAP memory

Hi Experts,
This is problem about ABAP memory.
I have two programs. Program-A & Program-B
Program-A sets value to variable and EXPORT command is used to set this variable in memory.
EXPORT variable TO DATABASE indx(st) ID 'KEYVALUE'.
Program-B gets variable using IMPORT command from memory.
IMPORT variable FROM DATABASE indx(st) ID 'KEYVALUE'.
User runs Program-A in SE38. Program-A calls Program-B using a button click event (SUBMIT).
The scenario is..
User1 executes the Program-A,
which set the variable = User1 in memory.
User2 executes the Program-A,
which set the variable = User2 in memory.
User2 clicks button to call Program-B,
which imports variable = User2 from memory.
User1 clicks button to call Program-B,
which imports variable = User2 from memory.
(But User1 expects the variable = User1).
So User1 gets wrong variable value set by another User.
How to handle this situation?. How to set memory variables user specific? I will appriciate all helpful answers.
Thanks in advance
Hari.

What you are using is global memory, if you don't want other sessions to see it, then you have to use a memeory id instead. This will work when submittin program b using the SUBMIT statement.
export variable to memory id 'ZRICHTEST'.
import variable from memory id 'ZRICHTEST'.
Or you can simply make your KEYVALUE unique by giving the USERID as part of it.

I've not found the option to increase shared memory of intel hd graphics card in BIOS

Hi! I don't find that option. I have the 2.08 version, but the 3.01 is out there. The graphics performance is not very well now. Is there a way to increase this memory to 256 mb or more? Thanks in advance

hi freinn,
Welcome to Lenovo Community Forums!
This is on Auto by default.
The amount of memory shared to your graphics is dependent on how much RAM you have. Also even if you max out the RAM capacity there will no big jump on the shared memory just few MBs will be added
The Manual is not available even if there is an updated BIOS.
Even if a Manual option is available still you can only share the same maximum as the one on Auto. Not a big jump.
i hate to say it but that's how it will be
Hope this helps

I want to increase my memory for oracle because i need to insert 31 billion rows into a table with nologging. I am inserting them chunk by chunk and commit after each chunk. But it is taking 62 hours to insert the rows. So i think if i increase the memory i could reduce the time to insert the rows.
I really am not sure whether i am thinking in the right way. Please advise. If i want to increase the memory please let me know how to increase it.
Thanks in advance

Can I increase heap memory without specify any class or jar file??

Hi,
I tried to increase my heap memory in this way :
java -Xms256m -Xmx256m
but I got an error ... it's seem that I must specify a class java or a .jar file ...
This is the error :
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-client to select the "client" VM
-server to select the "server" VM
-hotspot is a synonym for the "client" VM [deprecated]
The default VM is client.
-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A ; separated list of directories, JAR archives,
and ZIP archives to search for class files.
-D<name>=<value>

-version print product version and exit
-version:<value>

-showversion print product version and continue

What is it supposed to do with your request to use 256m of memory for heap
when you are not giving it a class or a jar to run?
