GC and Java Heap OutOfMemory

We have two applications on the same server - an Oracle data source, and the other used a source SQL Server. When the Oracle application is run, it uses the heap space but GC periodically runs and restores the memory. However when the SQL Server application runs, the heap can contain more and more memory until it runs out of space.

These two applications are running a very similar code, but just to point to different data sources. I read many entries of forum about OutOfMemory errors but this can vary, because even if the code allows memory to be released, the heap is finally released when CF expires and the soft numbers went (the standard 20-minute timer). This happens with the Oracle application but not the SQL Server application. Even when the "Session Timeout" variable is reached of heap memory is still being detained. The only way to retrieve that memory is by restarting CF.

It is a RedHat AS 4 Linux machine and it happens with CFMX7 and CF8 as a single server. I watched (very cool) with CF8 memory cards and you can see the peaks and valleys for the race of the Oracle, but the SQL Server application develops and grows.

I turned on the logging of pile and watched several iterations of Young GC followed by a Full GC. This pattern continues as the Oracle application is running. However, the SQL Server application starts like that, but as time passes he resorts to only full GCs until it reaches errors ' time GC is higher than 98% GCTimeLimit "and" means: Java heap space "errors.

So my questions are: given that the applications run differently on the same machine, could there be a difference between Oracle and SQL Server data sources and why doesn't CF never find the app disappeared and give back a lot space?

I found the answer, and unfortunately I was wrong in my original assumptions. It turns out that the code was different from one application to the other because one of them uses "cachedwithin" and the other not.

The developer thought that he had removed this code as a possible problem when he used zeros as parameters (as in "cache to 0 days, hours, minutes and seconds"). However, he always hides the same data. But when he took the cachedwithin setting completely, then nothing has been put in cache and the job remained calm.

So that we can see that we will have to pay much more attention to what is cached and when and for how long. A list of exactly what is happening in each part of the Java heap would be nice (session variables, data cfcache, cachedwithin, etc.) ...

means: space of Java heap in weblogic 10.3.3

Hello
After activation JSSE and changing encryption to < ciphersuite > TLS_RSA_WITH_AES_128_CBC_SHA < / ciphersuite > I received "means: Java heap space" every 2-3 days.
My java from settings is - Xms256m-Xmx512m - XX: CompileThreshold = 8000 - XX: PermSize = 128 m - XX: MaxPermSize = 256 m
and memory total is 1321 m:
total used free shared buffers cached
MEM: 1321 1249 72 0 39 163
-/ + buffers/cache: 1046 275
Swap: 2015 12 2003
Could you please advice/Xms Xmx whose size is more appropriate for my weblogic. And how can I solve this problem...
Thanks in advance!

Each process has a fixed size:

Size of the Java process = (HeapSize + MaxPermSize native memory)

Free-m command that you run only watch not the size of the heap rather total memory being occupied by the process. Also, it is not very useful to understand the actual use of memory by the JVM process. Then you should look at the log of GC and the Dump of the heap in order to know what kind of objects are fill up inside the pile.

Following article can give you an idea:

OutOfMemory Causes and first aid measures?

http://middlewaremagic.com/WebLogic/?p=4464

As an initial investigation to try to increase the size of the heap a little more as - Xmx1024m and activate the GC log.

space for the heap is going

If you think that the Out-of-memory is caused by the underlying ViewObject that retrieves and stores in memory

You can configure the VO with "Range Paging" access mode rather than the default access mode "Scrollable". With the access mode "Range Paging" the VO not go get and keep in mind all the lines until the currently selected line, but he keeps in memory a few line ranges (for example only a few dozen lines). This way you will not be affected by an OutOfMemory error even if the user scroll down to a millionth line.

I hope this helps.

Pages with errors of Java Heap
We run CF 8,0,0,176276 on a 32-bit Windows 2003 server with IIS 6 and Java Runtime version 6 (it's really version 1.06).
We started getting the java heap error messages two weeks ago. Now, we also receive the "GC overhead limit exceeded" error, which deals with the Java garbage collection. I tried to change the JVM from 1 GB to 2 GB heap size, but the CF would not start upward. I have since discovered that 32-bit Windows servers cannot use 2 GB for Java.
An article in java, I found said to disable Java cleaning using the - XX:-UseGCOverheadLimit ( http://forums.java.net/jive/message.jspa?messageID=228596). It seems that turn off garbage collection would be the opposite of what I'm trying to do. Are there any ideas on this?
Are there patches for CF8? and where are they located?
Scott
Scott, the error is a symptom, not the cause of your problems. Turning off this option will not "solve" the problem, it's that you are short of memory. More information about this option in a moment.

Let's talk about first your comment to try to change the 1 to 2 GB max memory. Since you're under Windows (32 bit), as you say, you cannot use more than 2g per process (this isn't really a limit of Java, but rather a Windows).

But you have found, you cannot assign CF 2 g because the JAVA virtual machine does not start. Again, this is not a question of specific CF. You can see the discussions on the same issue with plain old Java apps, to the http://forums.java.net/jive/message.jspa?messageID=228596.

So, similar to what they say, the consensus seems to be that you can set it to a between1.3 place and 1.7 GB, before of the JAVA virtual machine does not start. You have to try different values for yourself.

Now, that extra few hundred meg can be all that you need to get past your problem, but in reality that's often just to prevent the inevitable. You will need to find why CF uses as much memory. You say you use CF8 but do not say if the company or Standard. If the former, then you have the CF8 server monitor (available in the CF Admin and discussed in a several part series that I wrote for the center of Dev Adobe, such as discussed at http://carehart.org/blog/client/index.cfm/2008/7/30/45page_server_monitor_guide). That, as well as tools such as FusionReactor and SeeFusion, can help you to better see how FC uses memory.

All three offer a GUI to show how the memory usage is likely. You can see if it grows constantly throughout the day, or develops in spikes. People tend to say "I have a memory leak", when in fact, it may just be that they either a few requests that use too much memory (so you will see stairs Ford increase in the use of simultaneous memory with their performance), or it is possible that they are stick stuff in shared scopes (session (, application or server) and those who live well beyond the life of each request.

The CF8 server monitor has even a follow-up feature memory, but it must be used with caution. If you enable it, you can see that it brings to your server to its knees. I'll do a blog entry soon on how to use it more effectively (something I've learned since the drafting of the articles of the last year).

One thing the monitor can tell you, without that none of the buttons "start" at the top of the screen, it's how many sessions you have. This can be very informative. You can have thousands of them and not realizing it, because of robots, spiders and other requests for shit. See the page "active sessions" of the monitor server and its graphic icon in particular (discussed more in detail in one of my articles).

Unfortunately, neither FusionReactor nor SeeFusion can tell you how many sessions are running, so if you're on CF8 Standard (or if others reading of 6 or 7, where they can use EN or SF), you can't easily see how many sessions there is. (Ago undocumented, no supported methods, as discussed at http://rewindlife.com/2003/09/08/undocumented-application-scope-functions/. ) Just be aware that some techniques work differently depending on whether J2EE sessions are enabled in CF admin th.)

Finally, about your option usegcoverheadlimit observation and recommendation to turn it off: does not the article you point to do so would disable GC. I'm curious to know how you have concluded that. But digging into things, I see that turning off (using the - entry) will be disable a feature (introduced in 6) which limits the share of the virtual time machine happened to the GC before an OutOfMemory error is thrown. This is the error you see, that the JAVA virtual machine has detected much too much time is spent by the GC.

To disable the option is not "Disable Java cleaning." It changes just so an OOM error will be thrown even before being really out of memory, simply because a lot too much time is spent in GC.

And even then, how does this option (if enabled, what does default) change depending on if you use a parallel or concurrent collector (as discussed in two places in http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html, if you are looking for this switch).

Hope some of this aid.

CAP: Unrecoverable internal error: means: Java heap space

Hi guys, I get this error when I try to launch my application with Eclipse:

Unrecoverable internal error: means: Java heap space

It is at the stage of the rapc.exe of the compilation where this happens. I tried to remove eclipse and starting with a new facility, but in vain. Running my application worked once or twice, but then I tried to add a newer version of the BlackBerry JDE components, and that's where this problem started to occur.

Does anyone have an idea on how I can resolve this issue? Currently using the Eclipse of BlackBerry plugin components version 4.6.0.

Any help is very appreciated!

Tom

This must have been a configuration option. I backed up my Java files, deleted the project and then created a new project, and everything worked well. I have no idea what caused the problem in the first place, but I would recommend this as a solution, if someone else goes in.

Does garbage collection occurs in the region of PERM of Java Heap?

Hi guys,.

I am a new Member to this forum, my name is Javin Paul and I'm a Java programmer. I have a question related to the garbage collection in Java

Does garbage collection occurs in the region of PERM of Java Heap?

According to my knowledge PERM area is used to store metadata about classes, methods, variable etc also string Pool created in PERM area of the heap, so I believe that garbage do not occur in this place, but I just wanted to know what you guys think of it?

Thank you
Hervé

Basics segment of memory and so on that you are used to, do not apply the FMV of Blackberry - well they probably not, but it is well hidden from us. I recommend you check out this video to understand what you can control re garbage collection operation.

Before you increase the Max 6 GB heap size, it is 4 GB. After the question is change us to 6 Gb.Even after that the problem happened.
What can we do?
How much we need to increase? (Size of RAM 20 GB, virtual memory: 6 GB, 4 processors, 70%, use of memory virtual. 50% RAM usage)
Can - I need set the Min and Max Size as 6 GB?
Is there no changes have to make space PermGem?
We are using IBM j9 VM Jdk version 1.6.0?
How can we control java class wicj took more heap? (any tool is here)
Waiting for your answers...
Kind regards
Raj.

A 64-bit process cannot see that 264 bytes of memory. In practice, most operating systems limit each process to one or more less than the space available address, so that the kernel can handle 64-value which can be pointers to the kernel memory, memory of the process or memory device.

Maximum segment size of 32-bit or 64-bit JVM seems easy to determine glancing the addressable memory such as 2 ^ 32 (4GB) for 32-bit JVM and 2 ^ 64 for 64-bit JVM. Confusion starts here because you can't really put 4 GB as maximum segment size for 32-bit JVM options to the help - Xmx JVM heap. You get could not create the maximum segment size is not a valid virtual machine Java: error - Xmx. There are several reasons different segment space maximum for the FMV is less theoretical limit and vary from one operating system to another for example different in Windows, Linux and Solaris. I saw some comments on my post of 10 points on Java Heap Space about what is segment space maximum for Java or JVM 32 bit or 64 bit JVM and why Windows allows only of up to 1.6 G memory as the maximum segment etc. See more about this in frequently asked Questions about the Java HotSpot VM

The formula I posted is a generic. MaxPermSize may vary depending on the scope of application, number of JSP pages, classes etc contained in the request. It may not necessarily be 1/3 or 1/4th of Max Heap which is just a starting point tuning after that we need to see how much more PermSize is necessary. (However in your case, that PermSize adjustment is not necessary at this time because it is OOM's bunch)

Hello OPA Experts.
We receive above error in WAS (WebSphere Application Server) and Tomcat on determinations of the takeover server. We use the 10.4.4.21 OPA.
OPA application contains 12000 documents (size 5 MB) then we get the response ok. If the application contains 50000 documents (17 MB) and then in error response, after checking the log found below error:
means: Java heap space
How to increase the size of the java heap for the determinations server?.
Thank you
Moses.

Moses,

The heap size memory is to do with the JAVA virtual machine running the server of determinations of the OPA. It is under the control of the application server infrastructure in which you operate. In general, you cannot increase the allocation of memory for an individual web application, but need to increase the allowance for the server on which it is running.

Modify the application of memory for a web application varies depending on what Application Server. For example Tomcat works as a single server in a JAVA virtual machine and so it's just a matter of increasing the maximum memory (usually the flag - Xmx).

I'm not sure how Websphere works, but it should be a fairly simple task to find out how to increase the maximum memory allocation for a Websphere server.

See you soon

Discovered a lot of upgrade and java server connection

I'm about to upgrade my 4.6 5.3 view connection server. If I bump the RAM on my server connection view to 10 GB, the view connection Server Setup will modernize the resources of bunch of java along the way? The kb article and a SR, I had to open with VMware both said to uninstall/reinstall, but if I can improve I rather do.
http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 2009877
Thanks in advance for any help you can provide.

I think that the java heap is configured on a new installation. You can always update your current environment (to the current specification) and then create a new CB in the same group of replica with your 10 GB memory footprint. Which should allow an easy transition.

OUTLINELOAD means: higher GC limit exceeded; Java Heap Space

Any suggestions on how to fix this problem when you use the new OutlineLoad utility? I get incomplete. Files exported CSV and newspapers complain of exception OutOfMemoryError. Command and associated newspapers listed below.

Have you tried to increase the Xmx - value in the script - setHPenv.bat

I think it is defined as - Xmx512M so try - Xmx1024M or higher to see if it exports more disks

HAL & Java Heap Space error
Hi all

First of all, I know that we are late, but it's a challenge to try to get a update here.

We still use Hyperion Planning System 9. When it has been implemented, it has been implemented using HAL VA to add new members or members through the sketch. Recently, we started getting the following error when HAL running that requires the mobile members.

java.lang.RuntimeException: java.lang.Exception: means: Java heap space

Adding members is not a problem, that displacement. To my knowledge, nothing in the environment has changed and I tried to change the size of the heap in Contracting options, but this seems to just make things worse.

I know that there is an overall upgrade java done company wide, but that did not cause problems with other products.

I'll take ideas, because we have some massive moves to perform, and to make them all manually in the planning is a pain. It is much faster to use HAL.
He is member of entity you move, I know that this can cause a problem if it is permissible to workflow.
Having also enabled for the members version and scenarios that are not required to process management can impact so you better browsing and remove when it is not required.

See you soon

Hi Hussein

I have a question about this OPP java heap space.

Let's say I have 10 process allocated for the OPP and segment memory allocated to OPP is 1024 MB.

Q 1. Let's say 5 queries are run by 5 process OPP... So how this bunch of memory allocated?

is this something like heap space / number of applications being run by OPP (1024/5 in this case)

Q 2. Let's say that I filed 2 requests. A single application requires 800 MB of heap (based on the final races)
And second, it requires that 500 MB of space for the heap.

In this, we have java out of memory error? Am I wrong?

Q 3. Will, all applications submitted after after the test scenario 2 (2Q) encounter errors of memory, since the heap space was exhausted until the OPP bounced or full gc completed.

Please correct me if I'm wrong

-Thanks in advance.

Contour utility load - Java heap space problem

I thought it failed because of the parenthesis in the alias, but I don't think that's the case, since the fifth file without special characters or parenthesis also failed.

No idea why this isn't working and driving me crazy? John, are you still in place? It is only 20:50 in England, light! :)

Just so you know, we are on 11.1.1.3, and planning is under UNIX.

Thank you
Mehmet
I'm glad it's resolved :)

Hello

Looks like you are using generic Jar Installer... so in this case please run the Setup program by using option - Xmx1024m:

Example:
JAVA_HOME/bin/java - jar - Xmx1024m wls1001_generic.jar

As suggested in the following link: http://middlewaremagic.com/weblogic/?p=2731
