Java Aplication Maximum Memory size

Hi all,
im developing a fingerprint matching server that would load 10'000 fingerprints each fingerprint has 10KB, but the java application could only load 6500 fingerprints, it means, 64 MB of fingerprints then a java.lang.OutOfMemoryError appears, the machine has 512DDR on windows xp.
My question is,
Has Java any application memory limit?
If is that the case, what should i do?
Thanks for your attention

pass -Xmx256m as an argument to java will allow java to use up to 256 megabytes. You can specify up to around 1600m on Windows 32bit XP. In 64bit OS and 64bit java vm it is much, much higher.
type the following on the command line to see other options
java -X
and/or
java

Maximum Memory Size & Memory Size

Will a server's memory automatically increase from Memory Size to Maximum Memory Size as the VM requires it? Or is this only valid for adding memory to the Memory Size value manually?

Or is this only valid for adding memory to the Memory Size value manually?No, there is no automatic increase in memory. The max memory size just specifies the maximum amount to which you can manually adjust the memory of a running VM. I've now taken to setting the max memory size to the total available memory on my Oracle VM Servers, with memory size set to something reasonable. This way, I can adjust right up to the limit of physical memory without rebooting.

Java HttpSession Object Memory Size in Tomcat

Hi,
Is it possible to measure the size of a single session attribute [Any Object Let say String Object].
How Tomcat stores the HttpSessionObject in its memory.
Is it beneficial to have one object in session with say 7 String member variables than seven sessions. If it is then what is the estimated memory size difference in above scenario?

you can try this:
open your connection outside the function, and then pass it like as a parameter...
writePicture(OutputStream out, String siteID, Connection conn)
this can solve the problem because opening the connection inside the function spends a lot of memory...
Hope this can help you

Fernando

Specifying maximum memory size of a jar

We have the following issue:
We have a jar file which should be opened with double click. Our application needs a custom memory settings due to high amount of memory need.
Could we set this in the manifest.mf?
We read some resouces which tell that this is not possible, however the resources are not new. Was there any changes in the specification of the manifest file?
The resources which we read:

Maximum Memory size of Collections

hi,
can anyone please tell me how much data can be stored in a collection.
I would be using an Arraylist to store objects created at runtime, but i am not sure how much data can be stored into Arraylist.??
Please reply , Thanks in advance

The collections store object references and each one takes 4 bytes. Then there's an overhead by if you multiply with 2 you're on the safe side.Takes 4 bytes on a 32 bit platform... maybe. It's not specified by the JVM spec.Well, then use 8 bytes if you have a 64 bit platform. My point is that the objects aren't stored in the collection, just their references.
I was just offering a rougth estimate. If you've got something better please feel free to spill it out.
Say you store 1000 object references in an ArrayList. This will take no more than 1000 * 4 * 2 = 8000 byte.What about the actual objects themselves?Yes what about them. They're stored on the heap but not in the collection.
In general the sum of the memory of all objects is far larger than the collection that holds their references. So if there are memory problems it's seldom due to collections.

Maximum memory size

Hello,
another question about upgrades in my MacBook Alluminum (MB466LL/A).
According to the specifications, this MacBook only supports 4GB. But, I have a doubt! It's per slot or is a total amount?
Have you already tried to install 8GB (4GB per slot) in this MacBook?
Regards,
Felipe Perez

Here are the specifications for your model:
http://www.everymac.com/systems/apple/macbook/stats/macbook-core-2-duo-2.0-alumi num-13-late-2008-unibody-specs.html
Officially, a total of 4 GB is supported; but you can see that some third parties say you can use up to 8 GB - so that would be your decision to try it or not.

Is there a problem with maximum RAM size for Satellite 320CDT?

I have a Satellite 320CDT with the latest BIOS (v8.00) and Windows 98 SE installed; there is 32MB base memory and a 32MB module in the single expansion slot. If I change this for a 64MB expansion module I can still only see 64MB total memory reported, not 96MB as expected; the spec for the machine states that the maximum allowable memory is 160MB (32MB base + 128MB expansion). Does anybody know if there is a problem with the maximum memory size for this model and whether there is a solution or workaround? I need to know quickly, in order to decide if I need to return the memory module to the supplier! Many thanks for any help, Peter

Are you certain you tried the correct type of memory module? It sounds like you're maybe trying to fit an incompatible type.
There's a few different suppliers below.

K9N6SGM-V Maximum memory?

I just got an MSI K9N6SGM-V ( GeForce MCP61(V/S/P) + nForce 410 Chipset Based )
I was reading the manual and it says there on the memory support:
- DDRII 533/667/800 SDRAM ( 2GB max )
- 2 DDRII DIMMs ( 240pin/ 1.8V )
- Dual Channel
Does this mean I could only install 1GB memory per slot? or 2GB per slot which makes total of 4GB?
Any help would be greatly appreciated.

K9N6SGM-V is one version: http://global.msi.com.tw/index.php?func=proddesc&prod_no=1086&maincat_no=1
"Like my unit it says on the box MSI K9N6SGM-V ( GeForce MCP61(V/S/P) + nForce 410 Chipset Based ) while others MSI K9N6SGM-V AM2 NVIDIA GeForce 6100 Micro ATX AMD.."
It means the same.
Isn't it conflict if in the manufacturers manual it says:
Main Memory
• Supports Dual Channel DDR II 533/667/800
- 2 DDRII DIMMs (240pin / 1.8V)
- Supports a maximum memory size up to 2GB.
and then you'll make it to 4GB? I do not wan't to be a smart ass I'm just a complete moron on this.
I could still have it replaced from the dealer if it will make conflicton my PC's performance.
Thanks BOSSKILLER, I really appreciate your help

Maximum file size handled by java

Hi
What is the maximum file size that java can handle i.e if I need to read a disk file using java, is there any limit on the size of the file being read?

The size you can handle is not limited... only by your code :-)
Check MemoryMappedFiles... i handle Gigabyte files with no problem ;-)

How to calculate OS memory size in java?

I want to calculate free memory size , when I tried by Runtime class
like this Runtime.getRuntime().freeMemory() it gives JVS free memory size
But I want OS free memory size
If anybody know then plz reply me ASAP

Since the question was asked the last time (yesterday afternoon), I don't think Java has changed much, so the answer is still: you can't do it with Java.

Certain Java applets are crashing after increasing Memory Size to 1GB

The default java memory stellent uses in 384MB in the intradoc.cfg file. I recently updated both max and min to 1GB. Now I'm not saying memory increase is causing the crashes but I'm guessing. Say if I go to configeration manager applet and try to add a value or property, after clicking add the java applet freezes and I have to close the browser and restart again and same thing happens. Now the machine has in total 2GB of memory. I know that if java uses shared memory space (as the memory is increased to 1GB) with other application unpredictable random may happen. What do you think?

Hi,
i need do modify the intradoc.cfg to increase java memory. Can you send me all modifications that you apply in your intadroc file?
thanks!

How to get a java card memory size info ?

Hi everyone ,
I want to get my card's memory size and free memory size .I appreciate it if anyone could help me with these questions :
1 . Is there any way to find out card's defferrent memories size (EEPROM , ROM , RAM , FLASH) from Get Data command or any other apdu commands ?
2 . is there any function in the API which we could use to reach memory size within an applet ? I found a function named GetMemorryAccessInstance in JCRE 2.2.2 API but I need something more global for all API versions .
3 . Which Memories size information do we have access to ?
Best Regards,
Shemeine

Hi Shemeine,
Some cards have proprietary APDU's to find the free memory on a card. Even on cards that have such an APDU, you may have to have it enabled when the card is produced.
As for a way to find it programatically, you can use:
JCSystem.getAvailableMemory(JCSystem.MEMORY_TYPE_PERSISTENT);
JCSystem.getAvailableMemory(JCSystem.MEMORY_TYPE_TRANSIENT_DESELECT);
JCSystem.getAvailableMemory(JCSystem.MEMORY_TYPE_TRANSIENT_RESET);The problem with these is they return a signed short. This will only show up to 32KB of free memory. If you have more than this, you will have to allocate some memory using new byte[32*1024] until you start seeing results less than 32KB. You then work out how many blocks of 32KB you had to allocate to reach this state. The types of memory you can find are self explanatory.
Cheers,
Shane

Maximum heap size for 64bit JVM

Hi,
I am trying to set the maximum heap size for a java process in a 64bit JVM . I am not able to set more then 3G
command line config:
java -Xms64m -Xmx3g -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=8000 com.superpages.puboptions.CampaignFeedStarter >> publisher.out 2>&1 &

*64 bit JVM*
JDK1.6
where is this limitation coming from. How to set the heap size to 6g.
Thanks for your time
Meena

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.
$ java -showversion -d64 -Xmx6g HelloWorld
