Q: Minimum and Maximum Heap size ?
Hi Friends,
Can someone let me know like the minimum and maximum sizes required ?
I mean ,
What's the default minimum and maximum heap sizes (should we assign) for a 32-bit operating system ?
What's the default minimum and maximum heap sizes (should we assign) for a 64-bit operating system ?
Assume my operating system was LINUX.
thanks.

"Suppose say , if we observe lots of "FULL GC" occurring frequently.. What does this mean ?"
That the maximum heap space is reached frequently.
Another question that arises as well, what type of application are you dealing with. Is this an application that users are using, or is it an application that processes batches or something similar. In the first case you might want to check if you experience high pause-times due to these garbage collections, you could give the garbage collector some hints in what pause times you will allow (or by choosing a garbage collector strategy that runs concurrently). Note that it can also be a problem with the application, in the sense that it generates a lot of objects. For example, when the application performs adatabase query, how much data is that query collecting, and more importantly is that data really necessary. In the latter case you are not interested in pause time, but what the Java threads the have as much CPU-time as possible (and a garbage collection thread needs CPU too, of course), so in this case when you are dealing with very frequent garbage collections, you might want to increase the heap size (as this will less frequently trigger a full collection, i.e., you have more free memory to fill).
So based on the type of application, you might want to optimize for pause times (garbage collection pauses or minimized) or throughput (more CPU cycles for the application).

Q: heap issue
Hello,
I have set the minimum and maximum heap size to 512 M for the JVM. When I run my program, I keep gettting Java OutofMemory errors even though according to the Memory Window, I am only using about 100 M to run the program. I am using the NetBeans 5.0 IDE, so that's where I have the Memory Window. Can someone enlighten me as to how this is possible? The memory i am using shouldn't be anywhere near 512 M.
Thanks,
Jacob

A: heap issue
The memory window in the IDE represents the memory useage of the JVM that the IDE is running in. When you run your program, it executes in a new VM with default memory settings.
To adjust settings for your project, right click on the project node and choose the properties menu. In the dialog which is displayed, select the Run node in the tree on the left. Enter the -Xmx arguments in the "VM Options" textfield. Do not prefix with -J as that is something special for the netbeans launcher executable.

Hi there. I'm sure this question has been asked already, but my search of this forum didn't seem to find anything?
Is there a mechanism of supplying parameters to the Java Plug-in JVM, to control the minimum and maximum heap size, as there is with Java Webstart applications for example?
Thanks Neil

Hi,
try:

A: OutofMemory Error while sending file to database using Web services
Sorry for the delayed response here, forget to add it to my watchlist. I didn't catch if you were using Java 1.5 or not. Prior to 1.5 the default maximum heap space was 64MB which with the overhead of the appserver might be your problem.
Take a look at http://java.sun.com/j2se/1.5.0/docs/guide/vm/gc-ergonomics.html and the java -Xmx <size> command line option to change the default (I believe the size argument is in bytes, but don't hold me to that). I think you can pass that as a command line option to the startup script, but you should check the doco to see if it needs to be wrapped in some other arg etc.,
I seem to recall running into this same problem a few years back when I had a servlet doing some intense graphics processing on the fly and setting this option fixed the problem.

Hi All,
I am having confusion for providing hardware configuration for OBIEE setup.
We have most probably IBM AIX machine on which we have to insall OBIEE.
The Client has asked for the hardware configuration for the Setup. What would be the ideal setup for more than 50 users.
I have gone through the "System Requirement and Installation Guide for OBIEE" and it provide that it require 1Ghz Processor, 2GB Ram, some disk space like this.
But i also want some of the fact such as[b] what is the minimum and maximum heap size for OC4J and what is the optimum value of CPU cycle of the machine for good performance.
One thing more if i am buying OBIEE then Oracle appserver or OC4J license comes with that suite or i have to take seperate license for that.
Eagrly Waiting for reply. This will led to foundation of my first BI project.
Thanks in advance.

Call the Oracle Sales rep for your client. They can recommend something specific. Perosnlly, I would use the following as a minimum:
2 CPU; 8GB Ram in a production environment. You can run the Presentation Services and BI Server on the same machine. You can cluster in the future for scalability.

I am using the J2se 1.5.0_05 release of the JVM. I have customers that should get a lot of benefit from this feature. So, I have devised a test program to give us an idea of how much benefit will be derived and so that we can give our customers detailed instructions on how to use the feature.
I am trying to test the JVM and the test program using both the Windows XP Professional and the Suse Linux 10.0operating systems.
First Windows XP. The user code that runs the Java program has been granted the lock pages in memory. But regardless of whether the program is run with the -XX:+UseLargePages option is set on the Java command line, the program always seems to perform about the same. The Java command line also calls for a minimum and maximum heap size of 256M.
Second Suse Linux. The test machine has 3.8G of memory, the /proc/sys/vm/nr_hugepages parameter has been set to 524, the /proc/sys/kernel/shmmax amd /proc/sys/kernel/shmall parameters have been set to 4294967295, and the /proc/sys/kernel/shmmni parameter has been set to 100. The Java command line calls for a minimum and maximum heap size of 256M. Again regardless of whether the program is run with the -XX:+UseLargePages argument, the program always seems to perform about the same.
The test program simulates thousands of messages being sent back and forth between the various entities of a large enterprise, and is very math dependent to calculate the numbers of items that the various enterprise entities are to manufacture, order, and deliver to customers.
The statistics on how long it takes the various enterprise entities to repsond to various types of messages is used to guage the performance of the JVM.
Our expectations are that if the JVM is keeping the entire heap in large pages and those large pages are pinned in memory, that the test program will perform orders of magnitude faster than when large pages are not used.

Okay, I just found another article in this form written by dinoklein that seems to address my questions concerning Linux.
It indicates that the user running the Java program has to be able to lock memory and has pointed me in the direction of the /etc/security/limits.conf file to set that up. That seems in line with what I have found was needed in Windows. Both Windows and Linux require the user to be able to lock memory.
I will give that a try and see if that helps the Linux situation.
But, that has not yet helped the Windows situation. So, I would still like to know if there are other Windows options to which I need to pay attention.
Thank you for any help,

Hai,
We have created stand alone application using java swing. In our application we have read the text file (more than 100 MB). While reading that much size file we got "{color:#ff0000}java OutOfMemoryError: java heap space{color}" problem. For that we have set the minimum heap size as 10 and maximum as 128 MB. Does it cause any problem to JVM or any other software which are installed in my system? {color:#0000ff}Can we increase the heap size further?{color}
Thanks.

A: Increasing Heap size for java OutOfMemory Error?
If the application really needs more memory, you give it. If it's possible to change your implementations and you are going to do so, it doesn't need more memory.
What do you do with your text file? You read into your memory? If so, check how to stream from an InputStream directly into an OutputStream (like download a File from a server).
If you're displaying in a TextArea or something, here's a hint: when I open a 220MB logfile in UltraEdit, UltraEdit only needs 9MB of RAM ;)

Q: Java Heap
Hi
I have a webserver with weblogic510/SP6 and JDK1.2.2 running under windows NT. Recently we increased memory from 1GIG to 2GIG.
I have tried to change heap size to -ms512M -mx1532M
But I am getting error message "out of memory" during Weblogic server startup.
I have tried to setup minimum heap size to 25% of available memory and maximum is 75% of available memory. But it didnt work. I am trying to allocate maximum available memory to application. Please someone suggest me best solution.
Thanks

A: Java Heap
I have experienced a similar problem with wl510/sp9. I was able to set 320m / 2000m, but not 512M / 2000m. It wouldnt take 2048m for max heap size for some reason. Wierd part was it took 800m - 1200m bit not 512 / 1536 etc.

Hello,
We have a load balanced environment running ColdFusion 10 Enterprise with 5 instances currently running. Currently we only have one instance being actively used but have been encountering a problem within a time frame of 12 to 36 hours (calculated on the times we have had to restart CF to come back online) the garbage collection is running almost constantly and CPU holds at 50% until the server just becomes unresponsive until the CF instance is restarted.
I have been monitoring the server via VisualVM to watch the CPU and Heap usage since I have found that running the server monitoring systems build into CF 10 Enterprise accelerate the problem to cause a crash within 4 to 5 hours.
This issue has been occuring regardless if there is heavy load or not on the server. I have been seeing some odd behaviour when running CF Stat where I am seeing 4 Requests Queued and Running Requests never shows anything other than 0. I increased the Minimum Heap Size to 512 MB and Maximum Heap Size to 1024 MB and below is our JVM arguments
-server -XX:MaxPermSize=192m -XX:+UseParallelGC -Xbatch -Dcoldfusion.home={application.home} -Dcoldfusion.rootDir={application.home} -Dcoldfusion.libPath={application.home}/lib -Dorg.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true -Dcoldfusion.jsafe.defaultalgo=FIPS186Random -Dcom.sun.management.jmxremote.port=8701 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false
We are running on a Windows 2008 64 Bit and IIS 7.5 on both of the load balanced servers and have updated the server to ColdFusion 10 Update 2. I am aware of the issues that are being fixed in Update 3 that was removed last week by Adobe due to bugs introduced.
If anyone has any insight in how to fix this issue, I would be greatly appreciative. This is affecting a production server that did not show these problems when we put the servers under load when we did pre launch settings.

A: Garbage Collection and Constant CPU Usage
Further from your images - while it shows CF CPU at 50% the GC activity is 0%.
So could be your not garbage collecting more than necessary and something else CF wise is taking CPU time.
What would be interesting is the Jconsole Memory tab Details section. It shows the time spent in minor and major GC's. eg:
HTH, Carl.

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 for instance 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 development tests 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)?
2. Should Xms and Xmx be set to the same value (as mentioned in info from your website - see below), or are there situations where different values could improve performance ?
3. Is there other general advice you can give for improving performance using these settings ?

You may consider co-locating cluster nodes running in separate JVMs if you have

A: JAVA Max. and Min. Memory size
the java command has defaults documented here

i'm not sure this is the same as for applets (if thats what you mean by WEB based application)
You can find out at runtime using
Runtime.getRuntime().maxMemory(); // the hard limit
Runtime.getRuntime().totalMemory(); // how much of the hard limit has been claimed
Runtime.getRuntime().freeMemory(); // how much of the current total memory is free

We are running CFMX 7.01 Standard on Win 2003 Server in
single server configuration. Upgraded the memory from 1G (2-512) to
2G (2-1G) after a memory failure. Seeing we have more memory, we
changed the Minimum JVM Heap Size from 256 to 512 and the Maximum
JVM Heap Size from 512 to 1280.
Since doing so, jrun.exe runs using around 128mb of physical
memory and almost 1G of virtual memory/swap.
Any one have any ideas on what may be causing the up in
virtual memory usage? Seems silly to be gobbling up all that swap
file when it still has almost a full gig of physical.

A: JRun using excessively large amounts of swap/virtual memory
Thanx for the feedback. But it doesn't seem to make a
difference. We decreased the MaxHeap and the virtual memory usage
went down, but the real issue/question is why is it taking up so
much virtual/swap when there is 1.5G of free physical memory
available?
Looking at task manager, jrun is only using 128mb of physical
memory yet almost 600mb of virtual when there is 1.5G of free
physical memory.
This is our main production server that is running 1
Coldfusion website and MDaemon. MDaemon is used only for sending
out our website emails. There is a separate, dedicated company
email server for all other emails such as orders from the website
and all company emails. Our SQL server is also separate.
We also have a dev server that runs about 5 CF sites and a
handful of .NET sites. On that machine, jrun is using 350mb of
physical memory and max virtual memory usage is a little over
100mb. That has a setting of Max Heap of 512 and MaxPerm of 128.
This server probably gets beat up as much as the live seeing it
hosts the maint site for the website and the companies
intranet/reporting sites.
The only real setting differences except for the MaxHeap-Perm
is that the dev server is not set to save the class files. The
production server has more memory than the dev server yet it wants
to take more virtual memory than physical. I just don't get it!
Any help would be greatly appreciated!

Hi,
I am facing issue with Java process in AIX Machine. The issue is Java Process takes around 3GB memory, which is not acceptable in our environment.
We are running a Weblogic server in AIX environment with IBM JDK. JVM heap size is set to 512M for both maximum and minimum values. But still the process(java) is taking 3GB.
But the same application only takes 0.7GB for process in some other box with Websphere(AIX) and IBM JDK.
Is there any reason to occupy such a huge memory by Java process in AIX? Is there any way to control it?
Environmental Details:
========================
OS : AIX 5.2(Box is having 18CPUs and 14GB RAM)
Appserver : Weblogic 8.1 (SP4)
JDK : IBM JDK(1.4.2 ClassicVM)
JVM Command Parameters : -Xms1024m -Xmx1024m -verbose:gc -Xgcpolicy:optavgpause
Below command has been to get the process size of Java process (I never seen process size as 3GB. It was told by server admin).
ps -eo user,pid,pcpu,vsz,time,args
Here, vsz - gives memory size. Any idea why this is happening?

A: Java Process takes around 3GB memory in AIX Environment
Are there any regular GCs happening?
If so the memory will shoot up high. Otherwise there should not be any problem with WebLogic.
Are you using HotSpot or Classic Version of the JVM?
BEA recommends some specific JVM type for AIX Box. Check the documentation and see what they recommend.
If not raise a BEA Ticket for this problem. They should be able to resolve it for you.

Hi ,
The Java Heap Size changes are most likely due to garbage collection.
Add "-Xverbosegc:file=tempfile.out" to your start up script to get the
verbosegc
output to an external file.
eg : java -Xmx256m -Xms256m -Xverbosegc:file=tempfile.out -classpath
The output file may be created in some other directory than the one you

We have a Java application running on the Sun 1.5.0_09 JVM on a Solaris 8 server. When we started the application, we set the heap size settings as follows: -Xms256m -Xmx256m. With these settings we have typically found that a call to Runtime.getRuntime().totalMemory() will return a constant value over time, because we essentially set the maximum and minimum heap size values to the same size. However, we have a couple of systems where the value returned by Runtime.getRuntime().totalMemory() is decreasing over time. Can anyone explain how the total heap size can decrease when it has been set to a constant value? Note that we didn't have this problem on 1.4.2. We have only seen it on 1.5.0.
A: totalMemory Decreases Over Time
could be because of memory leaks or incorrect settings of jvm parameters like heap size, survivor ratio resulting in infrequent GCs. How much time does it take to loose significant amounf of memory ? have you looked at heap graph ? Typically application server admin consoles show heap graphs ..

We have two Win2k3 IIS CFMX webservers in a DNS roundrobin.
Periodically, they will report "JRun closed connection", and we
will have to restart CFMX to get it functional again. The errors

Hi Raf,
You can have for MTO Strategy 20, at the max you can have Rounding Values.
If your requirement can be fulfilled with Rounding then you need to maintain the below settings.
Transaction : OMI4

Is there a limit to maximum heap size. I know for EP6 SP2 the limit was 1536 mb.

A: EP6 SP4(NW04) and maximum heap size
First, the tuning guide suggests to start with 1024 and increase when you feel performance is suffering - and also do some validation that the larger heap is usefull.
Second, the paradigm has shifted from SP2 - as long as you have CPU capacity it is better to add more server processes with samller heaps. The old 1.5 CPUs / server still holds.
Third, the limit depends on your OS, ~ 2GB+ for 64 bit architectures.

In infotype 8 Annual Salary is showing 0.00
A: Minimum and Maximum amounts of a wage type
That is one location you could maintain the pay structure. Another place which is the same table is under
Personnel Management -> Compensation Management -> Job Pricing
In the area where you define your pay type, pay area, and reference salary with the start date and end date, towards the bottom there is a place where it ask you if you want to check for the range. You could specify to warn you, hard stop error, or no error.
This is how it works..
When you configure your pay structure with the min/max/midpoint in the pay table, you will configure it as "Annual Salary". So the frequency will need to be selected as "Annual" not monthly or any other.
In infotype 0008, when you enter in the annual salary, "IF" IT0008 is configured properly, it will auto calculate the wage type value based upon the workschedule assumption.
So let say the wage type config is usually set in accordance to the payroll area frequency of pay (also T510W controls it as well). Weekly, Bi-weekly, semi month, monthly etc.
The annual salary amount you enter will check back against the pay structure, given you have the right pay type, pay area, pay grade, and pay level matching the pay structure combination you've created. If the config is set to warn only, it will warn you saying the new annual salary amount is not within range. If it is set to error, you get a warning, but can't save at all. Or set to no error wher eyou don't see any error.
http://www.saphelpbykevin.net there is an article there that sort of explain basic pay usage.

hi,
I need to set the maximum heap size of the JVM. I know that I can do
it for a single run by saying:
java -Xmx75M example.class
But how do I make the JVM use this maximum heap size for all its
runs, without specifying '-Xmx75M' in every run.
I need this because I am using my system as a server for JSP web
site. For that site if a very simple query is given such as 'a' in title, as many as 6000
records as retrieved from my Filemaker Databases and the java
ResultSet object is not able to handle those records. The system is
then throwing an exception and error message 'Host not found' is
sent back to the client's browser. As far as I know, Filemaker does
not support 'LIMIT' keyword in queries.
So please tell me how can I rectify that problem.

Still I am having the problem that when some 5000 records are fetched from the database, the ResultSet object is not able to handle them. It is able to handle upto 2000 records. I am using windows2000, jdk1.3.2 and Filemaker Pro 5.0 databases.
I tried to set the maximum number of records that can be retrieved to 2000 so that the problem will be solved. But I am not able to set that as well. I did:
Class.forName("com.fmi.jdbc.JdbcDriver").newInstance();
Connection con = DriverManager.getConnection("standard statement");
PreparedStatement pstmt = con.prepareStatement("select id, pubyear, Checkedoutby, >>callnumber from mprrc_materials");
pstmt.setFetchSize(2000);
ResultSet rs3 = pstmt.executeQuery();Its giving the error:
java.lang.AbstractMethodError at that setFetchSize() statement.
I guess the JDBC driver provided by Filemaker Pro does not support that. So what can be done to solve the problem.

A: Maximum heap size for 64bit JVM
You need to use the -d64 switch to request the 64-bit JVM. E.g.,$ java -showversion -Xmx6g HelloWorld
Invalid maximum heap size: -Xmx6g
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.

Hello friends,
Can anyone tell me how to maintain minimum quantity in sales order, (Not Minimum order quantity of material master) as only maximum (target) quantity is maintainable in sales order at Item level? So after this development in sales order, one can enter two quantities (minimum and maximum) so that sale can be done between this quantity range.
I know this is not possible without exits or developments, but please tell if someone has came across the same scenario which exits used by you.
Thanks in advance

You can have your abapper code the Additional Data B screen user exits at the line item level. You will add two quantity fields - min qty and max qty. You will also have to code USEREXIT_CHECK_VBAP to enforce the rule that order quantity is between the limits.

Well, I don't really see whats exactly wrong, since i am using a for loop, every time it executes the grade is going to be a different number,Every time through the loop, you set both max and min to the current number.
5, 8, 9, 1, 7
max=5, min=5
max=8, min=8 Is 8 really the smallest number found so far?
max=9, min=9 Is 9 really the smallest number found so far?
max=1, min=1 Is 1 really the biggest number found so far?
max=7, min=7 Is 7 really both the biggest and the smallest number found so far?
so from the first input, that input is the min and max as of then, so i set the min and max to the grade.But you're doing that for every number.
There are two basic approaches.
1) As you're trying to do know, blindly initialize max and min to the first number--because, as you stated, it is both the largest and the smallest found so far, because it's the only one we have. Then for subsequent numbers only set max or min to that number if it's greater than max or less than min, respectively. That's where you're going wrong. You're setting max and min to every input, and then you're checking that input against max/min. But by this point the previous max/min are gone.
2) Initialize max to the smallest possible value you can get, or smaller. Initialize min to the largest possible value you can get, or larger. Then no special handling is required for first input vs. subsequent inputs.

Your requirements:
i want to have minimum stock level and maximum stock level,
and
... lot size is EX lot for lot order qty. Is there no way do maintain as per my requirement with this MRP type and lot size
are by definition incompatible. EX by definition means that when you have a shortage, the system will propose exactly enough to meet the shortage. If the shortage is for a quantity greater than the max, the system will still cover the shortage. It is possible, then, that stock will exceed max from time to time.
Within PD, you can get similar functionality to 'reorder point' by placing your 'minimum' number as 'Safety stock'. When the projected available stock falls below Safety stock quantity, the next MRP run will propose a replenishment order.

A: Maximum Heap size for better performance
You could try using these tools: http://www.javolution.org/ . They will help you control memory consumption and garbage behavior. The libs also take a fair amount of memory space, so it is not always very efficient to use.

A: maximum heap size limitations on Windows 32-bit
You should be able to use up to 1.5 Gig (-Xmx1500M) safely (as long as you don't create too many threads. If you fiddle with windows settings you can persuade windows to only use 1 gig of address space for the OS (rather then the normal 2) this will allow you to use up to 2.5G for heap.
Note that this problem is not caused by the amount of physical memory you have installed in the computer. It is a limitation imposed by the fact that a process on a 32 bit OS/machine can only ADDRESS 4Gig of ram. 2 gig of that address space is normally reserved for use by the OS (high 2 gig). The other 2 gig of address space can be used by the process itself (low 2 gig). That low 2 gig also has to load any static libraries and map any shared libraries reducing the available address space to about 1.5 to 1.8 gig.
The stack created for each thread also comes out of this "low" 2Gig (and is not part of the java heap). Therefore if you need to create lots of threads it is best to keep your max heap size below 1.5G.

I have a Windows 2003 64-bit server w/ 20GB that I'm running the 32-bit VM on. For the past several months I have been able to run VMs with the maximum heap set to 1500M. Recently I am no longer able to allocate 1500M. The maximum I can get now is about 1024M. The system has over half of the physical memory available when I'm am trying this allocation.
What could cause this change in behavior? The system experienced several OS patches and upgrades recently. Is it possible that these are causing Java to be unable to allocate a 1.5GB continugous memory space? After a bit of googling and discussions with others I am told that a new DLL could potentially be splitting up my virtual address space and preventing me from ever getting a continguous allocation of more than a gig. Is there anyway to confirm this and figure out what the culprit is? I was directed to vadump or ProcessExplorer but I haven't been able to parse the output well enough to determine what's going on.
