Max heap reached:Route Servlet:Out of memory
Hi All,
I have used max possible -Xmx value on a 32 bit Windows machine,
while starting oc4j from command line and the routeserver
initialization failed.
Did anyone face this issue or has any idea on how to initialize route servlet without errors
after reaching the max -Xmx value? Should we further partition the data?
Thank you,
-J
HI
On windows we have a limitation that heap cannot be more than 2gb.
You can have 2 JVM and check if it helps.
First and foremost you need to find whether there no objects leak in the code.

Out of memory: Java heap space
Hello,
I am working on a project, that simulates large populations, with each individual being a separate Objecta(a couple of kilobytes in size each).
Once i reach a bug enough number of those Objects (stored in a Vector), i get Out of memory: Java heap space exception.
Am i having a memory leak in Java? Or am i really reaching the maximal JVM limit and i need to reconfigure it, to support larger heap size?
:)Am i having a memory leak in Java?Because of garbage collection there, by far and large, aren't memory leaks in java. However, there certainly is memory waste.
If each of these objects you make room for are unnecessarily laden with references to other large objects creating huge networks of objects that never free their memory, and then you allocate 1 million of them, then, while not a leak, you are wasting your memory space.
Look through your class and inspect each field to see if any of them could be holding more data than you intend. If so, multiply the amount of that data by 1,000,000 or however many objects you are going to instantiate to determine if this produces and absurd amount of memory. You should be able to predict ~how much storage your data will need...each char is 2bytes, each int is 4 bytes, doubles are 8 etc -
Uploading large files from applet to servlet throws out of memory error
I have a java applet that needs to upload files from a client machine
to a web server using a servlet. the problem i am having is that in

The workaround is to use a socket connection and send your own request headers, with the content length filled in. You may have to multi-part mime encode the stream on its way out as well (I'm not about that...).
You can use the following:
http://porsche.cis.udel.edu:8080/cis479/lectures/slides-04/slide-02.html
on your server to get a feel for the format that the request headers need to take.

I get the out of Memory Error on the client side. I
was told that this might be a bug in the URLConnection
class implementation that basically it wont know the
content length until all the data has been written to
the output stream, so it uses an in memory buffer to
store the data which basically causes memory issues..
do you think there might be a workaround of any kind..
or maybe a way that the buffer might be flushed after
a certain size of file has been uploaded.. ?? do you
have any ideas? -
Out Of Memory Error every time my playhead reaches a slug I placed in timel
The past two days in one particular project I get an Error: Out Of Memory every time I play from the timeline and the playhead reaches the slugs I placed for the commercial breaks. I thought maybe the problem was with the commercial sequence I placed over the slug but I deleted it and still get the problem. When I get the message and then advance the playhead a little further to the right, but still over the slug, and press play I get a loud static cracking sound and the error message reappears. When I advance the playhead and hit play again FCP crashes. This happens in this order every time I reach a slug in the timeline. I am using FCP 6.0.5 (reinstalled last night) the project is HDV 1080i60 and I have a Mac Pro Quad Core with 6 GB of memory and I am saving to a esata Raid drive. I have ordered new memory although I do not think that is the problem. Why does stuff like this happen every time a deadline approaches?
meh... spoke too soon! I find that edit-to-tape (assembly edit on Sony HVRM-15 DVCAM mode) is unreliable whenever there is a slug in the timeline. Typically playhback crashes a few seconds after we hit the slug.
Im working around this by either using "black" clips rather than slug, or by dumping out the entire sequence to a separate QT movie, and then sending that out to tape.
Its puzzling that my current-gen quad-core mac pro (4GB memory total, NVIDEA 8800 card, seagate 250GB internal video drives) seems to be having such a hard time handling this... -
Download Servlet throwing Out Of Memory Exception
I am trying to download file of more than 500 mb through servlet but getting out of memory exception .
Before downloading i am zipping that huge file .
try {

outs.write(buf, 0, read);
fileToDownload.close();
outs.flush();
outs.close();
}catch(Exception e ) {
//Getting out of memory.
}Please suggest solution for this .cotton.m wrote:
My zip suggestion was as follows.
Take the file. Do not set the Content length header. Do set the Content encoding header to gzip. Create a GZIP output stream using the servlet output stream. Read the unzipped file in and output it through the gzip output stream.
This cuts out one full cycle of file reading and writing from what you are doing currently.Thanks for u r reply
InputStream fileToDownload = new FileInputStream(
file);
response.setContentType("application/gzip");
response.setHeader("Transfer-Encoding", "chunked");
response.setContentLength((int) file.length());
GZIPOutputStream gzipoutputstream = new GZIPOutputStream(outs);

while ((read = fileToDownload.read(buf)) != -1) {

Dear all,
In the config tool of a Java 6.40 system, for a server process I see the Max Heap size under Tab "General" and the Max Heap size under Tab "Bootstrap". What is the difference of these two values? If you can send me a link with documentation on this, it would be very much appreciated
Many thanks
AndreasCheck Note 876722 - the general setting for server node will take precedent over bootstap value
If you can see process details watch for -xmx value for the java process to find the actual value of the heap
Hope it helps -

Allocated Heap v.s. Max Heap and OutOfMemoryError
In my application, I specify heap size like following:
-Xms384m -Xmx384m
I got few OOME error recently. From our monitoring tool, I can see the 'allocated heap' was only about 280 - 340MB range when OOME happened. That means that the used heap size were close or reach the 'allocated' heap size but not the max heap that defined in '-Xmx'. My question is:
Why does JVM act like this? What is the problem that prevents JVM from obtaining promised memory from OS?
We are using JDK 1.5
Thanks,
JIts easy to check this, create as many threads as possible and configure a small heap size and a big stack size, count the number of created threads, then increase the heap and run the program again. Then you can see the number of threads increased too.
I have created a [java program to do exactly this, check it out|http://weblogs.java.net/blog/claudio/archive/2007/05/how_many_thread_1.html] .
See below, how thread stack size are allocated into the heap.
[http://java.sun.com/docs/hotspot/threads/threads.html|http://java.sun.com/docs/hotspot/threads/threads.html]
excerpt "TLEs (in 1.3) or TLABs (in 1.4) are thread local portions of the heap used in the young generation"
[Java Memory White Paper|http://java.sun.com/javase/technologies/hotspot/gc/memorymanagement_whitepaper.pdf]
For multithreaded applications, allocation operations need to be multithread-safe. If global locks were used to
ensure this, then allocation into a generation would become a bottleneck and degrade performance. Instead,
the HotSpot JVM has adopted a technique called Thread-Local Allocation Buffers (TLABs). This improves
multithreaded allocation throughput by giving each thread its own buffer (i.e., a small portion of the
generation) from which to allocate. Since only one thread can be allocating into each TLAB, allocation can take
place quickly by utilizing the bump-the-pointer technique, without requiring any locking. Only infrequently,
when a thread fills up its TLAB and needs to get a new one, must synchronization be utilized. Several techniques
to minimize space wastage due to the use of TLABs are employed. For example, TLABs are sized by the allocator
to waste less than 1% of Eden, on average. The combination of the use of TLABs and linear allocations using the
bump-the-pointer technique enables each allocation to be efficient, only requiring around 10 native instructions. -
Out of Memory Error running bea WLCS5.1
Hi everybody !
My team and I have to cope with the following bug :
Java.lang.OutOfMemoryError :
at weblogic.db.oci.OciCursor
at weblogic.jdbcbase.oci.Statement.executeQuery....
It runs under a cluster composed by 2 x BEA WLS 5.1 sp6.
heap min is 500Mo
heap max is 750Mo
total RAM is 1Go per machine
When memory use reaches 750Mo (max allowed), server should put
current instances in a queuing system while the garbage
collector is running.
At this point it appears that client requests are not queued but
canceled, returning an error to the client.
Why do we have to specify a heap limit if JVM goes over it anyway ?
Please give us a rope about it.Moi non plus.

Salut Laurent -
Faut que tu ecrit 'Mb' au lieu de 'Mo' puisse que les americains tecomprendre
The JVM does not exceed what you specify for max heap - the Java heap
is
only
part of the memory that the JVM uses.
Out-of-Memory exception occurs when the garbage collection cannot
recover
sufficient
memory for your application. A heap of 750Mb is very large - you may
wish
to verify
with JProbe that your application is not hanging on to memory that itdoesn't
need. Also the JVM arguments -verbose:gc will give you some additionalinformation
on GC. Specifying it twice will give you more information.

My analysis is that hashtable is causing this issue.
In my application I am using hashmap to store resultset objects and use request.setAttribute("databasevaluesforuser", databasevalues) to show in jsp.
Could it be that after the values are displayed the hashmap still contains those objects and when multiple users
access the application, heap size increases and this causes out of memory issues. I also paginated some jsp so that users view part by part of the results from database and thus prevent memory outage.
Could anybody help me in this issue. Please inform me if I need to provide any further information.Aplogies for answering late.
I am using SUN 1.4 jvm
The analysis of GC logs showed that lot of memory is consumed by java hashmap. In my application I am using hash map only to store the results from database and then represent at jsp using the request parameter. -
Out of memory error while deploying Oracle Service Bus Ressources
Hi,
When i am trying to deploy resources on sbconsole,it is showing below error on activation.

I have min and max heap size 3072M and min and max perm size set to 512M. I tried number of ways to solve this issue .
1. I restarted the weblogic and tried deploy again. every time i see the same error.
2. This steps turn out into whole mess. I deleted plan files from $domain_dir/osb/config/plan and again restarted web logic. After deleting plan files also , i can see all my proxies in sbconsole. Can somebody explain what is plan files in plan directory and ear files in sbgen? How OSB uses this ?
Thanks for your help
-Bplan.xml and ears are to deploy MDBs and customize them. When you deploy a Proxy Service who consumes JMS messages, OSB deploys a generic ejb.jar module and customizes it trhough a plan.xml (honestly I don't all all the nitty gritty)
in your case, for the OOM problems I am using a JVM option HeapDumpOnOutOfMemory, it's priceless, it produces a heap dump on which you can run a complete analysis with yourkit.com or Eclipse MAT. PRICELESS! if I were you, I would run such a test and send to Oracle Support the heap dump and your findings. -

Server goes out of memory when annotating TIFF File. Help with Tiled Images
I am new to JAI and have a problem with the system going out of memory
Objective:
1)Load up a TIFF file (each approx 5- 8 MB when compressed with CCITT.6 compression)
2)Annotate image (consider it as a simple drawString with the Graphics2D object of the RenderedImage)
3)Send it to the servlet outputStream
Problem:
Server goes out of memory when 5 threads try to access it concurrently
Runtime conditions:
VM param set to -Xmx1024m
Observation
Writing the files takes a lot of time when compared to reading the files
Some more information
1)I need to do the annotating at a pre-defined specific positions on the images(ex: in the first quadrant, or may be in the second quadrant).
2)I know that using the TiledImage class its possible to load up a portion of the image and process it.
Things I need help with:
I do not know how to send the whole file back to servlet output stream after annotating a tile of the image.
If write the tiled image back to a file, or to the outputstream, it gives me only the portion of the tile I read in and watermarked, not the whole image file
I have attached the code I use when I load up the whole image
Could somebody please help with the TiledImage solution?
Thx
public void annotateFile(File file, String wText, OutputStream out, AnnotationParameter param) throws Throwable {
ImageReader imgReader = null;
ImageWriter imgWriter = null;
TiledImage in_image = null, out_image = null;
IIOMetadata metadata = null;
ImageOutputStream ios = null;
try {
Iterator readIter = ImageIO.getImageReadersBySuffix("tif");
imgReader = (ImageReader) readIter.next();
imgReader.setInput(ImageIO.createImageInputStream(file));
metadata = imgReader.getImageMetadata(0);
in_image = new TiledImage(JAI.create("fileload", file.getPath()), true);
System.out.println("Image Read!");
Annotater annotater = new Annotater(in_image);
out_image = annotater.annotate(wText, param);
Iterator writeIter = ImageIO.getImageWritersBySuffix("tif");
if (writeIter.hasNext()) {
imgWriter = (ImageWriter) writeIter.next();
ios = ImageIO.createImageOutputStream(out);
imgWriter.setOutput(ios);
ImageWriteParam iwparam = imgWriter.getDefaultWriteParam();
if (iwparam instanceof TIFFImageWriteParam) {
iwparam.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
TIFFDirectory dir = (TIFFDirectory) out_image.getProperty("tiff_directory");
double compressionParam = dir.getFieldAsDouble(BaselineTIFFTagSet.TAG_COMPRESSION);
setTIFFCompression(iwparam, (int) compressionParam);
else {
iwparam.setCompressionMode(ImageWriteParam.MODE_COPY_FROM_METADATA);
System.out.println("Trying to write Image ....");
imgWriter.write(null, new IIOImage(out_image, null, metadata), iwparam);
System.out.println("Image written....");
finally {
if (imgWriter != null)
imgWriter.dispose();
if (imgReader != null)
imgReader.dispose();
if (ios != null) {
ios.flush();
ios.close();

U are right, SGA is too large for my server.
I guess oracle set SGA automaticlly while i choose default installion , but ,why SGA would be so big? Is oracle not smart enough ?Default database configuration is going to reserve 40% of physical memory for SGA for an instance, which you as a user can always change. I don't see anything wrong with that to say Oracle is not smart.
If i don't disincrease SGA, but increase max-shm-memory, would it work?This needs support from the CPU architecture (32 bit or 64 bit) and the kernel as well. Read more about the huge pages. -
Setting max heap in Oracle JVM
Hello -
I'm having a problem with a Java stored procedure running out of heap memory in Oracle 10g running Java 1.4.
Normally (running Java in a standard context) I would just modify the -Xmx with a higher value, but for the life of me I can't figure out how to do it in a stored procedure context.
I have browsed Google and I have browsed the Oracle JVM installation stuff, all to no avail.
Can anyone help me with how to set my max heap size, or verify that it's impossible? I have taken all of the standard Oracle memory parameters (JAVA_POOL, UGA/PGA/SGA limits) out of the picture by jacking them up and keeping an eye on memory values up to the point that the procedure fails (at ~700m), so I'm pretty sure that this is my problem.
So far I have looked at:
Config files
Config tables
DB parameters
I haven't been able to find anything remotely related to JVM option configuration in any of the above.
It is worth noting that I ran across another forum where someone was wanting to set their minimum heap size, and they were told that it was not possible. I'm just having trouble believing that it's the same story with something as critical as max heap size.
Much obliged for any help.
Thanks,
AnnakaFrom Metalink Note 466112.1:
Applies to:
Oracle Server - Enterprise Edition - Version: 9.2.0.1 to 10.2.0.3
This problem can occur on any platform.
Symptoms
When attempting to execute a java class that works fine in a stand alone JVM, fails with Oracle JVM with the following error:
ERROR
ORA-29532: Java call terminated by uncaught Java exception:
java.lang.OutOfMemoryError
ORA-06512: at "IDS_SYS.POD", line 3
Cause
The MaxMemorySize was set 256M (the default values) where the JSO needs memory more than 256 MB to run.
This can be checked as following:
SQL> create or replace function getMaxMemorySize return number
2 is language java name
3 'oracle.aurora.vm.OracleRuntime.getMaxMemorySize() returns long';
4 /
Function created.
SQL> select getMaxMemorySize from dual;
GETMAXMEMORYSIZE
268435456
After increasing the MaxMemorySize to a larger value(1 GB), the problem was fixed
Solution
Please increase the MaxMemorySize to a larger values(i.e. 1GB), this can be done as following:
SQL> create or replace function setMaxMemorySize(num number) return number
2 is language java name
3 'oracle.aurora.vm.OracleRuntime.setMaxMemorySize(long) returns long';
4 /
Function created.
SQL> select setMaxMemorySize(1024*1024*1024) from dual;
SETMAXMEMORYSIZE(1024*1024*1024)
Then you can check if the value is set correctly using the following:
SQL> select getMaxMemorySize from dual;
GETMAXMEMORYSIZE
1073741824
In my case I had to set the parameter within a job's the session.
