  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

  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)

• Request for recommendation Java Heap Size

  Looking for suggestions on the development. CF10 update 13 on a Server 64 bit with 8 GB of RAM, running in memory problems running (I think). JVM is only set to 256 / 512 at the moment, so I'm going to increase. CF and a handful of sites is pretty much all this server has.

  Suggestions on what I should put this now? We seem to be less than 50% at the time current (now 3.44 GB) memory usage and the CPU is 0-2%.

  Hello

  Maybe the minimum JVM and maximum 2048 / 4096. While your FMV alters ask a setting minimum permanent generation and the maximum value for EG permanent expansion:
  -XX: PermSize = 284 m - XX: MaxPermSize = 512 m

  You might do well to do some Java CF followed to find out what values suit better and if indeed the cleanings managed by - XX: + UseParallelGC work optimally. Logging Java can be run by a few traditional Java logging in a file then read file or passes through a tool. You can also use Jconsole, Jvisualvm or even the new control of the Mission (in the 1.7.0_40 release from) graphical tools.

  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

• 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.

• 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.) ...

• Change the maximum size of the JVM heap to 1024 gives error

  Change the maximum size of the JVM heap to 1024 gives an error.

  Environment:

  CF9
  Windows 2003 R2 Sp2 operating systems
  XEON PROCESSOR
  RAM 2 GB

  After the installation of ColdFusion, one of the parameters that gets changed is:
  Server settings > Java and JVM > (MB) 1024 maximum JVM heap size
  ColdFusion Application service does not start with this setting. A file of errors is created in \ColdFusion9\runtime\bin\hs_err_pid1234.log (where 1234 number changes). The details of the log file are long so soon stick a sample.

  
  Arguments for the JAVA virtual machine are:
  Java.args =-Server-Xmx1024m - Dsun.io.useCanonCaches = false - XX: MaxPermSize = 192 m - XX: + UseParallelGC-Dcoldfusion.rootDir={application.home}/... /-Dcoldfusion.libPath={application.home}/... / lib - Dcoldfusion.classPath={application.home}//lib/updates, {application. Home} /... / lib {cation.home} / app... /Gateway/lib /, {application. Home} /... / wwwroot/Web-INF/Flex/Jars, {application. home} /... / wwwroot/Web-INF/cfform/Jars

  The JVM max 1024 m is one of the commonly recommended changes. Why change the maximum FMV of 512 m prevents ColdFusion from running?

  It is indeed a strange problem. Something does not seem right/normal.

  I did some digging and found a blog entry potentially useful:

  http://iamgoat.com/post/804922016/ColdFusion-application-server-wont-start-after-Windows

  It looks just like your problem, but it is true, it offers a quite specific problem/solution, that may not apply.

  Here's another question: are you looking in the \runtime\logs directory? The log files it may show more information on the problem, maybe before or after the time that develop these logs of PID? They may be secondary to another primary problem. Search specifically for the OutOfMemory string in the log files.

  If that can't find anything, I would suggest another thought: consider changing the JAVA virtual machine. I see you are using 1.6_0_14. There are several points between it and the last _21 you can try.

  Finally, a thought more to consider: since this is the Hotspot compiler which reports the error (SH in hs_err_pidnnnn.log), it is possible that the addition of a switch to turn off Hotspot, just to go beyond that, could give a different error message with perhaps more information.

• 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.

• Is it possible to tell what is the heap size JVM is on a 64-bit 2008 Server?

  Is it possible to tell what is the heap size JVM is on a 64-bit 2008 Server? We have a number, but it is unclear if the connection broker has been installed before or after that RAM was brought to more than 10 GB.

  In the register of HKLM\SOFTWARE\VMware, Inc. \VMware VDM\plugins\wsnm\TomcatService\Params they seem to all State

  -Xms128m-Xmx4096m - XX: MaxPermSize = 128 m-Xrs - XX: + UseConcMarkSweepGC - Dsun.rmi.dgc.client.gcInterval = 3600000 - Dsun.rmi.dgc.server.gcInterval = 3600000...

  Although I've seen a show - Xmx1024m

  This could be how say you?

  Also did anyone know if a 4.6 view upgrade will increase the size of segment correctly if the RAM is increased before the upgrade to 4.5 takes place, therefore not having to do a complete reinstall?

  Thank you

  On page 69 of the installation guide, it shows how to change the JVM for X 86 servers.  Maybe this will give you a place to start looking for your current size.  On X 64 if it has been installed with the 10 GB of memory, then would be a chunk of memory to 2 GB size and anything less than 10 GB would result in a segment size of memory 512 MB.

• 3467K heap size exceed the threshold of notification (2048K)

  Hi all
  Windows 2003 Server
  Oracle 10g express
  
  I am getting this in my alert log at least twice every 5 min. Is anyone know why and how I can remove it. ?
  
  Notification of memory: Cache object library loaded in SGA

• The JVM maximum heap size

  I upgraded the memory in my server today from 1 GB to 4 GB.
  
  Went to set the size of the heap max 2 GB instead of 512 MB, and CF wouldn't restart.
  
  Manually changed the file config and is went back up to 1 GB (even a doubling of the size) and all is well.
  
  Tried to manually edit to something greater than 1 GB, and CF server would not restart.
  
  I did a lot of research on this and found conflicting info, etc..
  
  East Alexander, c. Adam or anyone out there who knows the suggested/best/reasoning for setting?
  
  CF MX 6.1 updated; IIS 6, Windows 2003 server, SQL 2003 sp 4.
  
  Thank you

  There are approximately 1.3 GB limit by the JVM heap. It's one thing to 32-bit.

  Send with a 64-bit JVM, then you can go higher. But Adobe only goes to support on Solaris.

  If you want more, go to the company and turn additional instances.

• 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.
