Java heap error

Hi All
I have developed a Matrix report recently and it is throwing error when it was loaded and ran locally and also after registerd in the Apps.The error is "Java Heap Error".Correct me if i am wrong to my knowledge what i am thinking is it is getting time out and unable to process the data.The report is running fine for few number of records.Please help me in this regard.
Help will be really apreciated.
regards,
kalyan

Hi kalyan,
What i know about Java Heap error is, it comes when you exceed the length allocated.
Sometimes it happens that you have to take the whole name upto 59 characters, means if somebody gets beyond the limit of 59, ideally you should truncate it.
If you dont, then it starts giving translation length error or say java heap error.

I had tried using -Xms / -Xmx options (upto 1 GB).
The trace of exception gets delayed (from being displayed on the console) as the memory size is increased; but after sometime it starts getting displayed on the console.
Even though this exception is displayed on the console, the Timer Bean continues to execute upto sometime before it finally crashes!
If anyone has encountered such problem; would appreciate if you could share the solution.

Hi guys, I have the same problem. I have an application EAR file with two modules (EJB and WAR starting in this order). The application can schedule a process via EJB timer. In this case restarting the server I receive the error above. If I change the modules start order --> WAR - EJB the server start correctly, but the application scheduler fails (the persistency is not working) with this error:

Pages failing with Java Heap errors

We are running CF 8,0,0,176276 on a Windows 32 bit 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 are also getting the 'GC overhead limit exceeded'
error, which is concerned with the Java garbage collection. I tried
to change the JVM heap size from 1GB to 2GB, but CF wouldn't start
up. I've since found out that Windows 32bit servers can't use 2GB
for Java.
One java article I found said to turn off the Java garbage
collection using -XX:-UseGCOverheadLimit (
http://forums.java.net/jive/message.jspa?messageID=228596).
It seems like turning off the garbage collection would be the
opposite of what I am trying to do. Are there any thoughts about
this?
Are there any hotfixes for CF8? and where are they located?
Scott

Scott, the error is a symptom, not the cause of your
problems. Turning off that option won't "solve" the problem, which
is that you're running out of memory. More on that option in a
moment.
Let's talk first about your observation of trying to change
the max memory from 1 to 2 gig. Since you're on Windows (32 bit),
as you say, you can't use more than 2g per process (it's not really
a Java limit, but rather a Windows one).
But as you found, you can't set CF to 2g because the JVM
won't start. Again, this is not a CF-specific issue. You can see
discussions of the same problem with plain old Java apps, as at
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 somewhere between1.3 and 1.7 gb, before the JVM
won't start. You have to try different values for yourself.
Now, that extra few hundred meg may be all you need to get
past your problem, but really that's often just forestalling the
inevitable. You need to find why CF is using so much memory. You
say you're using CF8 but don't say if it's Enterprise or Standard.
If the former, then you have the CF8 Server Monitor (accessible in
the CF Admin, and discussed in a multipart series I wrote for the
Adobe Dev Center, as discussed at
http://carehart.org/blog/client/index.cfm/2008/7/30/45page_server_monitor_guide).
That, as well as tools like FusionReactor and SeeFusion, can help
you to better see how CF is using memory.
All three offer a graphical interface to show how memory use
is trending. You may see if it grows steadily throughout the day,
or grows in spikes. People tend to say "I have a memory leak", when
in fact it may be just that they have either a few requests that
use too much memory (so you'll see a stair stepping rise in memory
use concurrent with their execution), or it may be that they're
sticking stuff into shared scopes (session, application, or server)
and those are living well beyond the live of each request.
The CF8 Server Monitor even has a memory tracking feature,
but it has to be used carefully. If you enable it, you may find it
brings your server to its knees.I'll do a blog entry soon on how to
use it most effectively (something I learned since writing the
articles last year).
One thing that the monitor can tell you, without any of the
"start" buttons enabled at the top of the monitor, is how many
sessions you have. That may be very enlightening. You may have
thousands of them, and not realize it, because of bots, spiders,
and other crap requests. See the "active sessions" page of the
Server Monitor, and its graph icon in particular (discussed in more
detail in one of my articles).
Sadly, neither FusionReactor nor SeeFusion can tell you how
many sessions are currently running, so if you're on CF8 Standard
(or if others reading this are on 6 or 7, where they can use FR or
SF), you can't easily see how many sessions there are. (There are
undocumented, unsupported methods, such as discussed at
http://rewindlife.com/2003/09/08/undocumented-application-scope-functions/.
Just be aware some techniques work differently depending on whether
J2EE sessions are enabled in th CF admin.)
Finally, about your observation of the usegcoverheadlimit
option, and the recommendation to turn it off: the article you
point to doesn't say doing so would disable GC. I'm curious how you
may have concluded that.But digging into things more, I see that
disabling it (using the - before it) will turn off a feature
(introduced in 6) which limits the proportion of the VM's time that
is spent in GC before an OutOfMemory error is thrown. That's the
error you're seeing, that the JVM has detected too much time is
being spent in doing GC.
So turning off the option doesn't "turn off the Java garbage
collection". It just changes whether an OOM error will be thrown
even before being really out of memory, simply because too much
time is being spent in GC.
And even then, how this option works (if enabled, which it is
by default) changes depending on whether you're using a parrallel
or concurrent collector (as discussed in two places in
http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html,
if you search for that switch).
Hope some of that helps.

OEDQ - Java Heap errors - thoughts?

I came across a rather annoying problem while trying to load data into OEDQ today and wondered if anyone can offer any insight.
2 separate installations (OEDQ 9.0.5) trying to load 2 different data loads (120k records and 35k records) both produced java heap errors while trying to create the datastore connection.
Following the various support articles regarding the java memory settings and systematically "playing" with the various values for min/max and reserved memory setting from dnconfig made no difference, the same java heap error every time.
I then noticed that the 2 data sources were both in the newer .xlsx format having been extracted to excel and then saved, I opened them and re-saved as first .csv and then .xls -- in both cases the data load now worked.
Given that more people will be moving to the newer xlsx format as "default" I wondered if anyone has any ideas on configuration to deal with what appears to be an added overhead when dealing with this format of files? we can of course just tell people not to use it but it would be nice to know why they cant.

Hi,
The current Excel driver works by pulling the whole of the spreadsheet into memory before capturing it. This can mean that with large spreadsheets it is possible not to have enough heap memory allocated to perform this function. This does not normally happen if using server-side data store connections as the server normally has considerably more memory allocated to it than the client application. If you do encounter this and cannot overcome it by adjusting the relevant heap memory settings, the workaround is as as you say to save as a CSV or other text files which can be streamed in (and out).
Probably the reason that xlsx files fail where xls files succeed is that the xlsx save creates a larger file.
Regards,
Mike

Java heap error when using compc

I have a large project, 100's of source files that I'm trying to compile into a swc. In Flash Builder 4 it works fine. When I try to do it in compc I get a Java heap space error. I've scoured google for help and haven't found anything useful. Does anyone on here know much about ant or compc? What am I doing wrong?
Here's the code that I use to compile. It gets all the files for me so I don't have to type them in one at a time. That part seems to work, it's when it calls compc that ant hangs for about 30 seconds then quits with a Java heap space error.

Latest nightly sdk causes Java Heap error during build

The latest nightly sdk 4.0.0.13210 causes out of memory error in Flash Builder during a clean build. However the prior nightly build (4.0.0.13175) works fine. I'm using build 262635 of Flash Builder. What changed in the latest nightly that could cause this problem. I have over 10 modules associated with this project. Here is details of the error that Flash Builder reports:
An internal error occured during: "Build Project"
An internal error occurred during: "Build Project".

Flash Builder 4.6 Java Heap Space Error

Hi,
I get this error "Java Heap Space" when trying to clean build (or build in any way) my project.
I have a lot of embeded assets (png, mp3 and some binary files embeded to be read as a ByteArray) which total about 37 MB. Including one more 1.6MB binary asset causes this error to occur.
I have tried to change my memory settings about (-Xmx and -Xms) as previous posts have suggested but this doesn't seem to make any difference.
Is there any patch or solution to this very frustrating limitation of Flash Builder?
Thanks for any help!
Tom

I constantly had issues with this. I managed to run into the max for increasing the heap space. I was able to get beyond the limit by flagging the FlashBuilder.exe file to allow it to allocate to higher memory address ranges. I'm on a 64 bit machine, so the only limitation was the 32 bit FlashBuilder process. Anyways i was able to get from 1024m up to 1720m. Also note that FlashBuilder 4.7 Beta is out and it is a native 64 bit application, so you will get higher addressing there. I just found it to be too buggy for my every day development tasks. Also missing the Design view really hurts development. I hope they put that back in.
Here's more detail on how I got beyond the java heap ceiling.

Java heap problem

Hi.
I have a question about objects in session scope.
I have created an object which holds a grid (a matrix of 2046 elements of HtmlnputText). At the beginning everything works ok, but later when several users create this matrix populating from database several times I get a java heap error. Reading several documents I think the object created are never released from memory so I don't know how to focus this stuff.
I have changed the scope of the object to resquest and the behaviour is the same..
Any comments about this?
thanks
PD: I use tomcat 6.0.x

Hi,
thanks both for comments.
I have no access to JVM, so I can't change it.
About the logic I think the problem is the GC is not working, I mean. when I get the recordset from database I make something like this:
Grid grid = new Grid(myData);
myData is an object populated from the recordset and I have defined the beans in request scope (not in session scope).
so everytime I make this, I lose the reference for the old Grid but I think this remains in memory so, when the application is running for some time it collapse and I get a java heap memory error. I'm not sure but I think that is the behaviour. Am I wrong?
Anyway I'll try with jmeter.
Thanks
greetings

When I try to load an image from the scanner, or from a file, into a bank deposit script, I get a message - "Error Java heap space". Need help to diagnose and fix this problem.

I am running a script from my banking facility which asks me to load an image of the front and back of the check. I never had a problem before, but this time when I try to load the images either directly from the scanner, or from previously saved jpg files I get an error window message that says - Error Java heap space,

Java Heap Space error while reading from Excel

Hello,
I have a data flow which reads from excel and updates records in an oracle table.
When the data flow tries to read the excel I get a java Heap space Error.

As Jay mentioned above it might be due to the size of the Excel spreadsheet as you might be hitting the limitation in Apache POI library used for adapter.
What is the size of the Excel file?
What is the value of -Xmx parameter - see DS Management Console > Adapter configuration page.
Thank you,
Viacheslav.

Java Heap Space Error in BI Publisher

Hi,
I have an issue with BIP reports.
My report is working fine in development instance as it has very less data.
But the same report is throwing "Java Heap Space" error in another instance which is having huge amount of data.
I tried to modify the oc4j.cmd file by increasing the values -XX:MaxPermSize=128m -Xmx1024m.
After restarting the oc4j serivices,my OBIEE and BIP URL's becomes dead slow.
Is there any solution to improve the performance (or) is there any other way to resolve this issue.
I am running on
OBIEE 10.1.3.4.2.
oc4j Server
Windows box.
Thanks in advance.
Pramod.

Changing os's may help, or it may not. Java requires contiguous memory addresses for the heap, and that varies with the os, os parameters, what has previously been loaded into memory, and how much physical memory is available. The heap can't be assigned to the os's swap space; the os handles paging in and out of memory. All modern os's provide paging to disk.
