Why do I get a java.lang.OutOfMemory exception
Thanks, in advance, for you help.
I just wrote a fairly large program. Every time I run it, I get a java.lang.OutOfMemory exception. I have no idea how to debug my code. Why would I get such an exception and how would I debug it?
put more debug statements
and see which line its giving that exception and see whether some where u have any line which is kind of looping or memory allocation .
As i havent seen ur code thats vague idea iam giving
java.lang.OutOfMemory exception is Thrown when the JVM cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector.
hope this might help

Java.lang outofmemory exception in IR
Hi
We are on XI 3.0 SP13 and involved in creating a message mapping. We have a big XCBL PO structure as the target - and while we do the mapping effort, every now and then, we get a java.lang outofmemory exception ( display error ) when we save the mapping.
I notice that my CPU util is 100% and is taken up by javaw.exe. I have a 1.6 G RAM desktop - but still face this problem. Any suggestions as to how to overcome this memory problem ? Am I missing any setting in my desktop ?? Or do we have to live with this problem since the target structure is a generic/big structure ??
Thank you in advance for your time.Hi
actually, this problem has nothing to do with the server at all. Also paging size and your desktop ram do not really matter. By default IB starts with the parameter -Xmx512M, what means that Java gets maximum 512M of RAM. You can change it saving JNLP file to your local file system and changing there this argument to -Xmx 800M or -Xmx 1024M.
The second way is to reduce schema sizes. Usually there are a lot of "annotation" and "documentation" tags. They can be easily removed withoud damaging the mapping(the only problem that in design time you'll not see a documentation for fields). If you want to go this way, you can tell me and I'll find out how it can be done by some tool. Because we had this problem with other customers and as I remember there were some tool made for this purpose.
Although it might help to install the latest SP, because there were made a number of changes to reduce a memory consumption for Message Mapping tool

Weblogic 8.1 SP4 getting Java.lang.outofMemory exception
Dear experts,
We are running WL8.1 SP4 on our Solaris 5.9 Server.
We want to do MQ implementatin on this server and for the same some kernel parameters were changed.
now our system has below parameters in /etc/system:
set semsys:seminfo_semmsl=1000

Java.lang.outofmemory exception
Hello,
I have an application, that writes several thousands of records into a file and transfers the same to the server. I am encountering an exception "java.lang.OutOfMemoryError" exception.
I had checked this forum earlier and found a solution that recommended an increase in the memory slot allocated to the JVM. Despite, an increase in this slot from 256MB (eclipse's default) to 1024 MB, my problem still persists. I had updated the eclipse.ini field from "-vmargs -Xms40m -Xmx256m" to "-vmargs -Xms40m -Xmx1024m". Is there anything else that I need to do, to take care of this problem? I am using green threads in the application, does this have anything to do with the above mentioned exception?
Thanks!I am using
green threads in the application, does this have
anything to do with the above mentioned exception?It wouldn't be hard to find out. Create a new java class where the main method does the same work; writing several thousands of records into a file and transferring it to the server.
Maybe it's all the other variables you have in your application that are cutting into the memory. But can you really reduce them?
Are you loading all thousands of records to memory (I'd imagine in a hashmap or a list) all at once? Like said, do this in smaller chunks, store the records in memory just one at a time and see if that works. It will be slow but it won't run out of memory. Then increase your "batch size" until you find the optimum. -

exception. Why it doesn't work as a servlet?

It still compiles, it just won't allow me to launch the program in the emulator. If I take that one piece of code out, everything runs fine again. I've been messing with it, and searching for a long time in an attempt to solve the problem but I've yet to come across a solution.
I'm also using Bluej

Sun identity manager - java.lang.OutOfMemory
Hi, I have one very interesting issue regarding JVM memory. I have one sun idm (version 7) application deployed in sun java web application server. I am facing JVM error - java.lang.OutOfMemory very frequently now days in production server. I am sharing you the details regarding configuration :
Their are 4 app servers - IDMAPP01 IDMAPP02 IDMAPP03 IDMAPP04
current total memory on each of the 4 app server 8 GB
memory allocated to JVM on each server 5 GB
os - solaris
admin task recon are performed only on instance - IDMAPP04
JVM setting is - -Xmx5g -Xms5g -Xmn1500m -XX:MaxPermSize=512m
Log file locations:
/var/opt/SUNWappserver/domain1/logs/vm.log
/var/opt/SUNWappserver/domain1/logs/gc.log
/opt/SUNWappserver/appserver/config/asadminenv.conf
/opt/SUNWappserver/appserver/config/asenv.conf
idm app deployment path:
/var/opt/SUNWappserver/domain1/applications/j2ee-modules/idm
logpath
/var/opt/SUNWappserver/domain1/logs/
Whenever I am getting this issue, we are restarting all the 4 server instances which is impacting business as this is prod server.
Can anyone suggest how can I solve this issue. (please suggest good performance tuning tips without increasing physical memory).

Whenever I am getting this issue, we are restarting all the 4 server instances which is impacting business as this is prod server.Why? The whole idea behind running recon on a separate server is that you can restart that one without affecting the others.
Can anyone suggest how can I solve this issue. (please suggest good performance tuning tips without increasing physical memory).
Enable gc logging and use a profiler to capture the behaviour of the jvm. You need to understand what it is doing and find where the problem area is before you can recommend what to tune.

Java.lang.OutOfMemory error while retrieving data from a large table
Hi,
i am trying to fetch data using "executeQuery()" into a ResultSet from the database. But since the data in that table is large. i am recieving "java.lang.OutOfMemory" Error. So, to resolve that, i have used "setMaxRows()" for my statement object. This resolved the error but i don't recieve the entire data. If i call "executeQuery()" again, i recieve the same data. I don't even know a filtering criterion where by i can filter the data for each "executeQuery()"..
How can i resolve this problem
Thanx in advance
--ChaitanyaEither use some criteria you develop related to one of the keys on the table or use some sort of record limiting method.
Note the method of limiting will vary related to the database you are using. You will have to look at the documentation.
For example I am told this will work in MySQL to get 200 records starting at record 100.
SELECT * FROM myTable ORDER BY whatever ASC LIMIT 100,200
Because you are running out of memroy I assume the table is large,
I am not sure what the impact of the above will have on performance because if in the above if the order by is not based on an index at the server level all the records will be selected and sorted before the records are limited.
I would make sure you have an appropriate index.
If you use the advanced search over the user forums using "resultset paging" and possibility the database you are using you should be able to get some ideas.
I hope this makes sense to you.

Unable to read big files into string object and java.lang.OutOfMemory Prob
Hi All,
I have an application that uses applet and servlet communication. On the client side I am reading an large xml file of 12MB size (using JFileChooser) and converting the file to an string object using below code. But I am getting java.lang.OutOfMemory on the client side . But the same below code works fine for small xml files which are less than 4MB sizes:
BufferedReader in = new BufferedReader(new InputStreamReader(new FileInputStream(file),"UTF8"), 1024*12);
String s, s2 = new String();
while((s = in.readLine())!= null)
s2 += s + "\n";
I even tried below code but still java.lang.OutOfMemory is coming:
while (true)
int i = in.read();
if (i == -1)
break;
sb.append(i);
Please let me know what am I doing wrong here ...
Thanks & Regards,
Sony.Using a String is bad for the following reason:
When you initially create the String, it has a certain memory size (allocated length if you will). As you keep appending to this String, then memory reallocation will occur over and over, slowing your program down dramatically (ive seen with a 16k x 8 Char file taking 30 secs to read into memory using Strings in this way)
A Better way would be if you knew the number of characters in the XML file (Using some File size method for example) Then you can use a StringBuffer, which will pre allocate enough space (or try to, it may just be that you cannot create a string as large as you need). You can use toString() method to get the resultant in a String Object (the extra allocated space at the end of the Buffer will be removed)
StringBuffer strBuf = new StringBuffer(xxxx);
Where xx is the length (int). Assuming that you are only allowed to enter an int to the constructor then (platform depedant) an int is 2^31 at maximum (or whatever) which allows 2.14e9 characters, therefore an xml file being totally filed would allow a size of ~2048 MB to be read in.
Try it and see. -

I could avoid the java.lang.OutOfMemory error using below code. But using below code I could read small files of sizes less than 4MB
but with large files of 12 MB the below code just simply hangs and I am unable to print the string object namely 's'.
My purpose is to construct an String or StringBuffer object out the user uploaded xml file at the client side and pass that object to server for processing. So how can I construct such object avoid memory problem and increasing the performance of such operations.
BufferedInputStream in = new BufferedInputStream(new FileInputStream(file));
byte[] b = new byte[in.available()];
in.read(b, 0, b.length);
String s = new String(b, 0, b.length);
in.close();

Cannot start OC4J instance - after java.lang.OutOfMemory errors
Hi, I have successfully deployed an application (using Oracle Web Services, J2EE - EJB, TopLink ) to a new OC4J instance that we created. We use the OEM web site to manage the start/stop and deploy operations.
Then we tried to run simultaneously 10 clients....against the server app... ran ok for a while and after approx. 5 to 10 min... java.lang.OutOfMemory errors were being thrown at the client.
After a set of OutOfMemory errors, other clients received errors like the ones show below:

Im not sure if this is due to a memory leak or something in my app ? Or does Oracle IAS / Toplink have any such issues for which any possible patches are available ?
Could anyone please direct me in the possible right direction !
Thanks,
KrishnaHi,
We have had this problem too, it only started after we deployed to production and got some load on our application server. We are using JRun as our application server.
We found that Macromedia (JRun) already addressed the issue in general - that if you get java.lang.OutOfMemory errors, then you need to increase the heap size.
Previously we had been using our own caching mechanism and never ran into this problem. Since we decided to go with TopLink (which has caching) we no longer use our own caching mechanism... but now we have this problem.
We have chosen to use FullIdentityMap for caching, but didn't think we would run out of memory in the JVM. Is there a suggested or minimum JVM memory requirement to run TopLink?
Thanks,
Aaron
