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.

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?

Confusion on Java heap memory and WLS_FORMS

Hello all,
Background first:
Oracle Forms/Reports 11.1.2 64-bit
WebLogic Server 10.3.6
JDK 1.6 update 37 64-bit
Microsoft Windows 2008 R2
Using nodemanager to start/stop managed servers
After having read all of the documentation and searched both this forum and the Internet for advice, I'm still utterly confused about the best way to make use of memory on the server (the server I'm working on now has 8GB). The two trains of thought that I have discovered in my search:
1). Don't change the Javaheap size at all (stick with the defaults) and just create additional managed servers on the same machine.
2). Increase the Java heap size for WLS_FORMS
Having said that, here are my questions:
A). What is the best-practices approach (#1 or #2)?
B). If it's #2, what's the approved way to increase the heap size? I have tried adding -Xms and -Xmx arguments to the WLS server start arguments in the WLS console. These are applied when the managed server is started (confirmed in the log file), but because of the way WLS_FORMS is started, there are more -Xms and -Xmx arguments applied after mine, and Java picks the last one mentioned if there are duplicates.
First update: Question #2 seems to be answered by support note 1260074.1 (the one place I hadn't yet looked)
Thanks for any insight you can provide. If there's a document I've missed somewhere, I'm happy to be told where it is and will read and summarize findings here.
Regards,
John

John,
Let me try to comment on each of yours:
1). We had been getting some "Apache unable to contact the forms server" type errors (the users were seeing the "Failure of server APACHE bridge" error). The log files showed nothing of interest. I increased the memory allocated using setDomainEnv.cmd, and the error seems to have gone away. Yes, I know that it was a shotgun approach, trying something without really having a reason to do so, but it seems to have helped Edit: Now that I review the OHS logs instead of the WLS_FORMS logs, I have found log messages, which leads me to Doc 1380762.1, which tells me I need a patch. DOH. And, oh crikey, Forms 11.1.2.1 is out, it came out shortly after we downloaded 11.1.2.0 to create these environments. Good news/bad news kind of thing... <blockquote>The Apache Bridge error is fairly straight forward if you understand what it is telling you. It is an error generated by mod_wl_ohs who is owned by OHS (Apache). This module is responsible for the connection between OHS and WLS. The Apache Bridge error means that OHS (mod_wls) was unable to get a response from the WLS managed server it was calling. Basically it was unable to cross the bridge ;) The cause could be anything from the managed server is not running, to the managed server is over tasked, or there is a network configuration issue and the managed server simply didn't hear OHS calling.
This is all discussed in MOS note 1304095.1
As for 11.1.2.1, this can be installed fresh or as a patch over 11.1.2.0. So for machines that don't currently have anything installed, you can go directly to 11.1.2.1 without having to install 11.1.2.0 first.</blockquote>
2). As tony.g suggested, we are looking for what we should do to solve the "I have n servers with x GB of RAM, what should I do to the out-of-the-box configuration of Forms for stability" question. <blockquote>As I mentioned, there really are no "Forms" specific tweaks related to how much RAM your machine has. The only exception to this is (although somewhat indirect) to use JVM Pooling. JVM Pooling can reduce the size of each runtime process's memory footprint by moving its java calls to the jvm pool then sharing common requests with other running runtimes. Memory usage by OHS or the WLS managed server really has little to do directly with Forms. Specifically to the managed server, from a Forms point of view, I would not expect the memory cost of WLS_FORMS to increase much because of load. I expect it to increase as concurrent load increases, but I would not expect it to be significant. If I had to guess, seeing an increase of 1m or less per user would not surprise me (this is just a guess - I don't know what the expected values would be). If we were to use our (Oracle) older scalability guidelines, typically we would have suggested that you should consider about 100 sessions per 1 jvm for best performance. Given that v11 uses a newer java version and scalability is better today, I suspect you can easily scale to a few hundred (e.g. 300) or so before performance drops off. Beyond that, the need to add more managed servers would likely be necessary.
This is discussed in MOS note 989118.1</blockquote>
3). HA is important to us, so we are implementing a cluster of Forms/Reports servers with an LBR in front of it. I have read in the docs on clustering, cloning a managed server, and via Support, how to increase the heap memory for the WLS_FORMS server. My thought process was "if Oracle gives me instructions on how to increase heap memory and how to clone managed servers, there must be a scenario in which doing so provides benefit." I'm trying to understand the scenarios in which we would do either of those activities. <blockquote>Refer to the note I mentioned above. Generally, if you limit the number of concurrent sessions to less than around 300-400, I would think the default settings should be fine. If you think you would like to go beyond 300 or 400 per managed server then likely you will need to increase the max heap for the managed server. Again, refer to the note I mentioned previously.
Also see MOS note 1260074.1</blockquote>
I am aware of the JVM pooling (yes we do call out to Reports) - I've yet to implement this, but it's on my to-do list.
<blockquote>This is discussed in the [url http://docs.oracle.com/cd/E38115_01/doc.111210/e24477/jvm.htm]Forms Deployment Guide</blockquote>
Hope that helps ;)

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?

OAS Heap memory issue: An error "java.lang.OutOfMemoryError: GC overhead

OAS - 10.1.3.4.0
We are running out of Heap memory and seeing lots of full GC and out of memory events
Verbose GC is on.
Users don't know what they are doing to cause this
We have 30-40 users per server and 1.5 GB heap memory allocated
There are no other applications on the machine. Only the PRD instance with 1.5 GB allocated to the JVM. We do not have any issue with memory on the server and we could increase the heap but we dont want to go over the 1.5 GB since that is what I understood to be the high end of what is recommended. we only have 30-40 users on each machine. There are 8 servers and a typical heavy usage day we may have 1 or two machines that have the out of memory or continuous full GC in the logs. When this occurs the phones light up with the people on that machine experiencing slowness.
below is an example of what we see in a file created in the OPMN log folder on the JAS server then this occurs. I think this is the log created when Verbose GC is turned on. I can send you the full log or anything else you need. Thanks

Allocated heap memory goes up even when there is enough free memory

Hi,
Our Java application's memory usage keep growing. Further analysis of the heap memory using JProbe shows that the allocated heap memory goes up even when there is enough free memory available in the heap.
When the process started, allocated heap memory was around 50MB and the memory used was around 8MB. After few hours, the inuse memory remains at 8MB (slight increase in KBs), but the allocated memory went upto 70MB.
We are using JVM 1.5_10. What could be the reason for heap allocation going up even when there is enough free memory available in heap?

Increase JVM memory using Java Code

Hi Friends
I am in a critical situtation and not able get the solution. My application is huge and need of increase in JVM memory. I am able to increase JVM memory in command prompt
java -Xmx500m classname
Simarly I am able to run jar file also
java -Xmx500m -jar sample.jar
I need to know how to set JVM memory for executable JAR. When I just double-click the JAR application load and i am getting Out Of Memory. I dont what ti use command prompt to execute. Please help me with this program. Thanks in advance

I gone through the code of ImageJ software. ImageJ is
a freeware and wrtten in Java. They are setting jvm
memory in code, getting the description of the code
was difficult.
long memoryBytes =
s = Runtime.getRuntime().maxMemory();
     long memoryMB = memoryBytes/1024/1024;
     long memoryDiff = memoryMB - 64;
String s = "Runtime.maxMemory: " + memoryMB +
B + "MB\n";
     s = s + "Difference: " + memoryDiff + "MB";
     System.out.println("s..." + s);
The above code will give you the memory allocated for JVM. Yes.
When there is a way to find the memory space,
there should be some way to set it. No.
I am still trying to set the memory in code r using external resource.Read reply 4.
I want to just give the executable jar to users. They
are not satisified with the bat file and hidding
command prompt in background.You may be able to use Runtime.exec() to launch another instance of java, with whatever heap setting you desire.

Changing heap memory paramter and Additonal Java node configuration

Hi All,
Kindly provide me the procedure to change the heap memory parameter and location (in Visual admin). How to install/configure 2nd Java server node in PI system.
Thanks in advance.

Hi Ramesh,
You would have posted this question in Netweaver Administrator forum...
Well here are the answers.
Login to Configtool.
Expand Cluster-Data->instance<xx>->dispatcher. On the right hand side you can change the heap size for the dispatcher
Follow the same procedure to increase the server heap memory.
To add the server node click on instance<xx>. Then click Server->Add server.
Cheers....

Find heap memory Size for Web Intelligence processing server in BO 4.0

Hi All ,
We need to gather data for sizing inputs.For Adaptive processing server , we can find same by going in CMC> Server > APS > Properties & check value for the parameter -Xmx . Could you please tell how to find the max heap memory allocated for a Web Intelligence processing server in BO 4.0 as for Webi server this parameter is not maintained. ?
Regards ,
Abhinav

Hi Abhinav,
The maximum threshold is a value which may reach on peak usage and Webi processing server cannot occupy memory beyond this value at any time.
In your situation 9 Webi Processing servers with 16 GB of RAM on server is not recommended. This is because consider situation with total 16 GB of host RAM.
4 GB should left for OS
Tomcat will need minimum 2 GB for 200 users
So you are left with 10 GB RAM for all BO services
Now 9 Webi Processing servers with 6 GB of Threshhost will not work here
For this configuration you can have 2 Webi Processing servers with default threshold should be running on single host.

Threaded inner classes & heap memory exhaustion

(_) how can i maximize my threading without running out of
heap memory?
push it to the limit, but throttle back before an
java.lang.OutOfMemoryError.
(_) within 1 threaded class ThreadClass, i have two threaded inner classes. for each instance of ThreadClass i only
start one instance of each inner class.
and, i start hundreds of ThreadClass, but not until the previously running ThreadClass object exits, so only one should be running at any given time.
so, what about threaded inner classes?
are they good? bad? cause "OutOfMemoryErrors"?
are those inner threads not dying?
what are common causes of:
java.lang.OutOfMemoryError: java heap space?
my program runs for about 5-minutes, then
bails with the memory error.
how can i drill down and see what
is eating-up all my memory?
thanks.

A Thread class is not the same as a thread of
execution. Those inner class based threads of
execution are not dying.maybe. but this is the way i test a thread's life:
public void run() {
System.out.println("thread start");
System.out.println("thread dies and release memory");
}for each inner thread, and the outer thread, this approach for
testing thread life reveals that they die.
Why don't you use a thread pool?ok. i will think about how to do this.
>
If not, you need to ensure those inner threads have
exited and completed.what is a 100% sure check to guarantee a thread exits other than
the one i use above?
note:
the outer thread is running on a remote host, and the inner threads
are running locally. here are the details:
public class BB implements Runnable, FinInterface {
public void run() {
    // do some work on the remote machine
private void startResultsHandler(OisXoos oisX) {
     ResultHandler rh = new ResultHandler(oisX);
     rh.start();
public void startDataProxy(OisXoos oisX, String query) {
     DataProxy dp = new DataProxy(oisX, query);
     dp.start();
        public class ResultsHandler extends Thread {
           // runs locally; waits for results from servers
           public void run() {
               ObjectInputStream ois = new ObjectInputStream(oisX.input);
                Set result = (Set) ois.readObject();
        } // ____ class :: _ ResultsHandler _ :: class ____
       public class DataProxy extends Thread {
           // runs locally; performs db queries on behalf of servers
           public void run() {
               ObjectOutputStream oos = new ObjectOutputStream(oisX.output);
                while(moreData) {
                    .... // sql queries
                    oos.writeObject(data);
             StartResultsHandler(oisX);
        } // _____ class :: _ DataProxy _ :: class _____
}now, the BB class is not started locally.
the inner threads are started locally to both service data requests
by the BB thread as well as wait for its results.
(_) so, maybe the inner threads cannot exit (but they sure look
like they exit) until their parent BB thread exits.
(_) yet, those inner threads have no knowledge that the BB
thread is running.
externalizing those inner thread classes will put 2-weeks of work
in the dust bin. i want to keep them internal.
thanks.
here this piece of code that controls everything:
while(moreData) {
FinObjects finObj = new BB();
String symb = (String) data_ois.readObject();
OisXoos oisX = RSAdmin.getServer();
oisX.xoos.writeObject(finObj);
finObj.startDataProxy(finObj, oisX, symb);
}

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.

How to Increase the memory size of a File in the Application Server

Hello Abaper's

But , while transferring the XML file to Applicationserver , it's transferring only upto max 4 Records.I     assume that the memory is insufficient to allocate 10 Records. Can we Increase the Memory size of the File on Application server. OR, is there any error in My Source Code.

Problem increasing heap size using Java Control Panel

I am running a web-based bioinformatics package which uses a Java applet as the client application. It mostly works fine, but some large clustering processes don't complete, they just cycle endlessly. The user manual advises increasing heap space "by entering the following command in the Java Control Panel or Java Plug-in dialog: -Xms128M -Xmx256M." I can open the Java Control Panel OK and enter the necessary command in the Java Runtime Parameters box, but after clicking OK then Apply, the Runtime Parameters box is empty again and there is no increase in the heap size allocation. In other words, the change doesn't take effect.
I have already tried: adjusting one parameter at a time (max heap size first, then min); changing uppercase to lowercase M (-Xmx256m); restarting the browser after the change; rebooting my PC - none of these has helped.
Technical details: it's Java 6 standard edition, build 1.6.0_10-rc-b28; browser is Internet Explorer 7; operating system is Vista (Service Pack 1); PC is a 2.4 GHz processor with 2 GB RAM (so I have plenty available to allocate to Java). I have local admin privilege on my PC.
Help would be much appreciated, as I really need to complete these cluster analyses. I'm a biologist not a developer, so ideally I need a solution that doesn't involve major programming, though I'm OK with registry edits and use of the command line. Thanks in advance.

The failure to retain the parameters is a bug, per hdong in this [Java,net thread|http://forums.java.net/jive/thread.jspa?threadID=44540&tstart=0] dated August 14
"I did a little more research and found out that the problem is only with "-rc" or "-beta" versions of plugin. When 1.6.0_10 is finally released, the version string will be "1.6.0_10". Plugin works fine to set/get jvm parameters when version string is "1.6.0_10".
I am surprised that this issue was not discovered earlier. It was probably because the internal test binary use "1.6.0_10" as version string.
Yeah, it is a bug that will affect many manny developers. It will be fixed as soon as possible."

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
Cheers!

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

Are all columns in the WHERE clause indexed?
Are statistics current & accurate for all tables & indexes?
