You are running out of memory. You can change the allocated java heap space for reporting if you haven't tried that already.
Here is a thread regarding how to change the java heap space. Oracle recommends setting your -xmx to 1024.

Hope this helps,

and rerun the DBCA and the problem still there.
How to solve this problem?

Getting java.lang.outofmemoryerror: Java heap space error

I am using coldfusion 8. I frequently get the error 'java.lang.outofmemoryerror: Java heap space'. Can anyone help me?
Error Details :
500
Root cause:
java.lang.outofmemoryerror: Java heap space
javax.servlet.servletException: Root Cause:
java.lang.outofmemoryerror: Java heap space
Thanks in advance,
Regards,
Satheesh.

Well... what does the error message tell you is wrong? You're running out of memory. I presume you understand how computer memory works, if not specifically how Java memory allocation works. So... you have x amount of memory, and you're trying to use >x amount of memory. You can't do that. There are two approaches to dealing with a problem like this:
a) have more memory;
b) use less memory.
What are your JVM memory settings? They're in jvm.config dir, which'll be - by default - in your Jrun4/bin dir for a multi-server install, or somewhere like ColdFusion/runtime/bin or something like that on a stand-alone install.
Next... what are you loading into memory? This is trickier to answer. But every variable you create takes up memory. People often load up the application or session scopes with stuff that's "convenient" to store in shared-scope memory, but really chew through it. Putting CFC instances in the session scope is a really good way to waste memory, as they seem to have quite a large footprint.
It's really impossible to say what's eating the memory based on what info you've given us (basically: none), but you can use things like FusionReactor to examine what's going into memory. Or CF* Enterprise has some of its own memory profiling stuff... I've never used it but it might be of some use.
Have you googled "coldfusion java.lang.outofmemory"?

How to solve this ERROR --java.lang.OutOfMemoryError: Java heap space

I am Trying to read one TEXT file line by line. file size is approx. 7 MB or it contain approx. 35000 line of text.
i am processing that file and export data into another file.
mean while after some line i get error like below,
java.lang.OutOfMemoryError: Java heap space
After this error process stop.
my application is in Java Swing and i m using java 1.5 version of SDK and JRE.
is it a JDK version Problem?
please can any one give me appropriate solutions for this.
give me answer please.............

Are you able to post the code you use to read the file? Initially, I'd guess that you're stuck in a loop. Make sure you're getting out of all your loops. You can do this with breakpoints in your IDE's debugger, or by putting a println right after the loop.
It may also be that your IDE isn't allotted enough of your system's memory, though I doubt that is the case. You can easily google how to increase the memory allotted to the IDE.
For some reason, garbage collection isn't happening as you're expecting. Make sure you're not holding on to huge stuff any longer than you need to.

BPEL 10.1.3.x deployment error: java.lang.OutOfMemoryError: Java heap spac

I am using IBPELDomainHandle.deploySuitcase() API to deploy a bpel process. Each time, I got ServerException with the following error message: java.lang.OutOfMemoryError: Java heap spac
What configurations should I perform to the BPEL server in order to get rid of the outofmemeory error?
BTW: I was able to deploy the same bpel process by uploading the jar file to $OH/bpel/domains/default/deploy directory.
Thanks,

Hi Qian,
Check the -Xmx JVM setting in the OC4J_BPEL configuration. Raise the amount of MB to allow JVM to use more memory.

Servlet.service() Error. java.lang.OutOfMemoryError: Java heap space

Hi All,
I would be very grateful if you would draw some light for this error I got from running a online database connected image viewer (applet).
The application is quite simple, applet connect to servlet, servlet send 3 SQL statements to MySQL and retrieve image info (Strings) and 50 Files (- JPEG image) from a online database, and then pass all of data to applet from servlet. The size of total of images is around 3.5 MB, and I've increased JVM memory to 128 MB by using code "-xmx128m".
? Do I need send images from servlet to applet individually rather than push them in one go
? Is there memory leak in my codes
Please see the codes below:

wire the code into a simple unit test, then run a profiler on it to see where the memory is going. You need the help of these kind of tools to track down memory issues, before that it is only guesswork what might be soaking it all up.

Tomcat Error: "java.lang.OutOfMemoryError: Java heap space"

Hi,
We are on BOXI 3.1 SP3. We are using Tomcat as a application server.
After certain time interval tomcat server hangs and users are unable to login to Infoview. When we checked in catalina.out file, we got error "java.lang.OutOfMemoryError: Java heap space". As a workaround, we restart tomcat server. That time we are unable to stop tomcat server using tomcatshutdown.sh script and we need to kill it forcefully. Once we restart the tomcat server, occupied memory free up and users are able to login to Infoview.
Below are my observations on this issue:
1. We have observed that this is not happening only during peak time/heavy load on system, but is happening during weekend as well which shows that it is not related to user load.
2. Issue occurs intermittently.
3. Tomcat is unable to release unused memory. It just adds the memory and reaches it's maximum allocated memory.
I raised SAP case for this and they suggested to add parallet garbage collector parameter. but that did not help.
Below is heap size setting for Java under /Install Dir/setup/env.sh:
JAVA_OPTS="$JAVA_OPTS -Xmx1024m -XX:MaxPermSize=256m -XX:+UseParallelGC"
Below are my environment details:
Product : BOXI R3.1 SP3
Linux: Redhat 5.3
RAM: 10 GB
Web Application Server : Apache - Tomcat
I am thinking that somehow tomcat is unable to free up it's occupied memory which is not used by any object further. It just keeps adding memory and reaches its maximum threshold limit which is 1024 MB.
We have installed SP3 on server last Sunday. Issue was there before SP3 installation as well and it was occuring very rarely. But after SP3 installation, it is occuring on daily basis. Is there any known bug in SP3.
Any help would be greatlt appericiated.
Thanks,
Swapnil Rodge.

Hi Sebastian,
Did you use the -Xmx2048m setting for Tomcat? If yes, how did it work for you? When I do the same tomcat refuses to start.
Thanks,
Vinayak

"java.lang.OutOfMemoryError: Java heap space" while trying to read Excel.

Hi Experts,
Here is my query. I'm trying to upload excel data into database table. This excel contains more than 20000 records. I'm storing this data in a vector after reading it & passing this vector as a parameter to another method(not mentioned in the below code) which writes into the database. The code works for records <4000, but fails to read beyond that & throws exception as below.

HOW did you increase the heap space? As that is the only solution you have in this case really.
It is a known fact that POI can use up a lot of memory for big spreadsheets. If at all possible, I would try to switch to plain text comma separated files / tab delimited files. If you cannot do that, I would try to put a size restriction on the sheets that your application will process to get rid of the heap space risk. A sheet can contain 20000 records, or four sheets can contain 5000 records; in both cases you process the exact same data, but at only 25% of the total memory usage.

i have a huge XML file of size 9 MB. I need to parse it and store it in a MYSQL database. When i execute the program, it throws me out of memory error and only 12668 rows have been inserted into the database. I use SAX parser to parse the XML. i have also given the stack trace of the error below. Kindly let me know how to resolve the issue.
I have also changed the JAVA_OPTS to -Xms128m -Xmx512m but this didnt solve the issue.

Check your code where u set the connection query; there's a procedure in my DBConnection class, looks like this:
public void setQuery(String query) throws SQLException {
this.query = conn.prepareStatement(query);
Should look the same for u, at least similar.
I set the query this way: dbConn.setQuery("insert into groups (id, code, sectionID, languageID, year, no_students) values (?,?,?,?,?,?)");
I had to insert 24,827 records into a table, and it throws the heap space exception u mentioned when it reaches 12,667. So what i did was to put dbConn.setQuery(...) outside the loop, and inside the loop it remains to set the parameters and execute the query from connection. It works for me. Hope will help u save some memory space.

Trouble with "java.lang.OutOfMemoryError: Java heap space"

Hello,
I use a Java-based modeling tool that very few out there are probably familiar with. This tool allows me to run models (program) from within the development environment, to create Applets or create jar files that can be executed in a stand-alone fashion.
I am using a database on my local harddrive to read in some data using JDBC, so am not using the Applet option with certificates. The development environment is expensive, so can't be distributed. That leaves the stand-alone option.
The model (program) I've written runs perfectly fine in the development environment and, previously, has worked fine as a stand-alone program. However, the stand-alone option isn't working anymore, because I keep getting this error.
I am not much of a Java programmer; I'm learning as I go along. If anyone can help me solve this, I'll be most appreciative
From my cmd prompt:

Hi I am ancountering the same problem with the 'heap space'.
Is there any way I can find out what it is set to for my system? I dont believe its 32Mb and dont want to increase it randomly to too large a size if theres no need for it.
Thanks,
Bobby

Finally, the problem was :
    jstring str;
    for(int i = 0; i < xxx.GetSize(); i++){
        CString cstr = xxx.GetAt(i);
        str = env->NewStringUTF(cstr.GetBuffer(0));

        /* release memory */
        env->DeleteLocalRef(counterUIName);
    }The "DeleteLocalRef(counterUIName);" should be made for each iteration.

Thanks for your help

pretty obvious to me "java.lang.OutOfMemoryError: Java heap space"
Read,
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/jsts/(Kernel)OOM
or
java.lang.OutOfMemoryError: Java heap space
those links should give you a fairly good idea on how to solve the issue.
