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....

How to change heap memory size for general java applications (not applets)
Hi. I made a java class which manipulates images and I sometimes get an out of memory error when the files are large. In these cases I can run it successfully from the command line using:
java -Xms32m -Xmx128m myappbut as I run this class from a firefox extension, I can't use this technique.
Could some one tell me how to set this globally? I've found a lot of info on setting it for applets in the control panel but that's it. I also tried editing my deployment.properties file by adding:
deployment.javapi.jre.1.6.0_11-b03.args=-Xmx128mbut none of these options seem to work.
Thanks for any help.Also you can use use [JAVA_TOOL_OPTIONS|http://java.sun.com/j2se/1.5.0/docs/guide/jvmti/jvmti.html#tooloptions], with more documentation here. JAVA_TOOLS_OPTIONS is available since 1.5. There is no direct documentation on [_JAVA_OPTIONS|http://java.sun.com/j2se/1.5.0/docs/guide/2d/flags.html] but was made available since at least 1.3.
The recent existing forum thread [Java Programming - How to change the default memory limits for java.|http://forums.sun.com/thread.jspa?threadID=5368323&messageID=10615245&start=36] has a long discussion on the issue.
You specified you are not using applets, but if you do, I would also suggest you use the next Generation Plug-in (since 1.6.0_10) that allows you specify the max memory in the applet without having to instruct the user how to make the change. See [JAVA_ARGUMENTS|https://jdk6.dev.java.net/plugin2/#JAVA_ARGUMENTS] for applets. Java Webstart uses resources. -
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

P965 (7235) memory timing and CPU-Z 1.36...
There's a problem with memory timing (overclock).
Motherboard: msi p965 neo-f(7235) with bios 1.5
memory: kingmax mars ddr2 667 mhz 4gb (4 * 1 gbytes) base timing 5.5.5.15 at 333 mhz.
and 4.4.4.12 at 266 mhz
Processor: Intel E6600
OS: winxp 32bits
If i set "dram timing" to "manual", the ddr memory frequency is adjustable.
In bios,i set the ddr memory frequency to 667 mhz for a "FSB:Dram" --> "4:5" (320 mhz cpu fsb frequency with 400 mhz ddr memory frequency)
Timing is set to 5.5.5.15 and overclock is 9*320 = 2880 mhz
But cpu-z 1.36 says "dram timing 5.5.5.23"
If i change "dram timing" to "manual" (because i can change ddr memory frequency) and all timings to "auto", cpu-z 1.36 says "dram timing 5.5.5.15"
Ok i know, the memory is out the Specification.
But now timing is set to "4.4.4.12" and i change the ddr memory frequency to "533 mhz".
The "FSB:DRAM" is "1:1" (320 mhz cpu fsb frequency with 320 mhz ddr memory frequency).
Then cpu-z 1.36 says "dram timing 4.4.4.20"
If i change "dram timing" to "manual" and all timings to "auto", cpu-z 1.36 says "dram timing 4.4.4.12"
The question is:
why bios don't respect my choice when i set memory timing ?
Thank you... If you understand what i wrote...Quote from: NovJoe on 26-August-06, 14:17:48
So there is indeed an advantage gain. CPU-Z needs to do some updates on their software now.
Well, I personally will not try Corecenter myself as it has given too much problems since it's 1st launch.
Corecenter does the job well, but what i said it's just possible ameliorations for perfection
Quote from: Maesus on 27-August-06, 01:32:06
Well, overclocking limit is highly depending on the parts you get, there is no guarantee of reaching your wanted overclocking speed by any part unless special tests and validations have been done on the parts. But no RAM manufacturer has done that... So, it's all depending on your luck!
I know, for the overclocking capability.
My little overclock, is what i thought with this motherboard. this is good for silence and consumption.
But it's just a problem with my memory and voltage more than 2.10 v. I'll do tests later, this is not important. But as i like to know the capability
finally if i have bought this motherboard, there were 4 raisons.
first a good price.
Three pci ports.
A minimum overclocking.
And before all, a mainboard with very good stability.
This is my first msi motherboard
This simple mainboard p965 neo-f does not disappoint me
Thank you with the regulators to help to solve the problems.
And It is nevertheless the best place to speak about it -
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,
JohnJohn,
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 figure out the size of an object - java out of heap memory error
Hi all,
I am using an object that I found in a library that I didn't create so I don't know its internal state or members.
I created a single one of these objects and I call announce() on this object which just sends a UDP announcement over the channel to notify listeners. However, after a message #124,288 I get a java out of heap memory error.
I am wondering if this announce() method is causing the state of the object to grow with every call...it seems unlikely but I want to check to see if it's reserving a growing amount of heap memory without ever allowing it to free.
My question is how can I check how big the object is within my program? I'd like to check, for instance, at every 10,000 messages sent how much memory the object is taking up. Is there a method call for that? Would I have to use some kind of debugger or memory monitor? I would like something easy to use.
Please let me know, and thanks in advance.
Julianjboolean23 wrote:
Thanks for the quick reply.
I say it's unlikely that the methods I call are filling up heap memory because I have one Message object. This one Message has a myMsg String member. Whenever I want to change the message I call myMsg = "anewstringhere". And then I do myMessageObject.announce(); And for that reason i say I only have one Message object. The only thing added to the heap would be the strings that I replace myMsg with. The old references to myMsg are no longer valid and should be garbage collected..
Unless of course if you are calling intern() on them.
so here's my train of thought (and this isn't what my actual code looks like):
myMessageObject.myMsg = "hello" //creates a string on the heap? I assume this is equivalent to saying myMsg = new String("hello")No they are not the same.
The text literal will be in the intern space. Both code fragments would do that.
The second example would create a second instance of String(). That second instance would be cleaned when no longer referenced. But the literal will not.
Is my thought process correct? You are calling a third party library right so mock it (write a simple replacement that does the minimal correct functionality.) Substitute it in your code. And then run. If it still fails then the problem is in your code. If not then it is either in the library or the way that you use the library. -
Is there a way to define the ideal size of the java heap memory?
Hello all!
Is there a way to define the ideal size the java heap memory? I'm using a server with (IR,FR,WA) installed and i'm using the Windows Server 2008 R2 with 32GB of ram memory. I have other server with the same configuration using essbase. How can i set the heap memory? I have around 250 users (not simultaneous).

How to change Virtual Memory in Windows 7 with SSD and 16GB RAM
I have SSD Samsung 850Pro with OS Windows 7 and have installed physical RAM 16GB.
In Adobe Help/Optimize performance/Photoshop written :
" To change Virtual Memory in Windows 7 and Vista, quit all applications and then do the following:
Choose Start > Control Panel, and double-click System.
Choose Advanced System Settings in the Tasks list.
Select the Advanced tab and click Settings in the Performance section.
Select the Advanced tab and click Change.
Deselect Automatically Manage Paging File Size For All Drives.
Click each hard disk letter to show the available space on that drive. Select a hard drive that has three times the amount of your computer’s installed RAM and doesn’t contain a scratch disk.
Select Custom Size, and type the amount of your physical RAM plus 300 MB in the Initial Size box. Type three times the amount of your computer’s installed RAM into the Maximum Size box.
Click Set, and then click OK. Continue to click OK to exit all dialog boxes.
Restart the computer: If you have applications open, select Restart Later, close your applications, then restart Windows. Otherwise, click Restart Now. "
Select Custom Size, and type the amount of your physical RAM plus 300 MB in the Initial Size box. Type three times the amount of your computer’s installed RAM into the Maximum Size box.
I have 16GB RAM
in the Initial Size box : 16384+300=16684MB
in the Maximum Size box:16684x3=50052MB
but in the description of SSD written :
" In order to address any potential lack of memory capacity, the Windows operating system automatically generates a block of virtual memory (pagefile.sys) on the C: drive. For example, a Windows® 7 64-bit system with 4 GB of physical memory would generate 4 GB of virtual memory at boot time.
In the past, before PC Memory (DRAM Modules) were available in high volume, PCs needed to utilize some HDD space to address any memory shortcomings. Today, with PCs featuring 4 GB of memory or more, it is possible to reduce or even eliminate the use of virtual memory. Additionally, using expanded physical memory, rather than creating virtual memory on the SSD, has performance and reliability advantages for the entire system. Some applications may require the use of virtual memory. In this case, please consider your specific application requirements before disabling this feature!!! ”..."SET virtual memory in the Initial Size Box :200MB and in the Maximum Size box: 2048MB"
what is the right choice ???
Please HelpWindows set to default virtual memory : 16348 MB =16GB !
But SSD program Samsung Magician wants virtual memory between in the Initial Size Box :200MB and in the Maximum Size box: 2048MB or 4096MB. If more than 8GB suggests that SSD will work slowly.
Perhaps the description in Adobe execution Help / Optimize / Photoshop is not correct or ? -

I have a iMAC(got it in less than 2 months ago), can I change the memory(upgrade it from 4 GB to 8GB) myself? I mean I need to open the screws and exchange the memory chips. Does it cancel the guarantee?
No, unless you break something or install the wrong RAM, new RAM is not covered by warranty/AppleCare of course.

I tried to change the memory and now my Imac will not power on. and there are no beeps. what did I do wrong?
Don't know. Could be any number of reasons. Re-read the how to install RAM manual again for your model iMac. Double & triple check to make sure you purchased the right RAM chips. Make sure they are seated properly. If you didn't hear a snap when seated, the RAM is not properly seated.
