Database out of memory error getting Web Intelligence prompts

The following code generates an exception for a particular web intelligence report object ID:
m_engines = (ReportEngines)m_entSession.getService("ReportEngines");
m_widocRepEngine = (ReportEngine)m_engines.getService(ReportEngines.ReportEngineType.WI_REPORT_ENGINE);
DocumentInstance doc = m_widocRepEngine.openDocument(id);
Prompts prompts = doc.getPrompts();
The exception is as follows:
A database error occurred. The database error text is: The system is out of memory. Use system side cursors for large result sets: Java heap space. Result set size: 31,207, 651. JVM total memory size: 66,650,112..(WIS 10901).
I can't understand how the result set could be over 31 million, or how to fix this. Any ideas?

So what happens in InfoView?
I ask since it doesn't appear to be a SDK coding issue.
Sincerely,
Ted Ueda

Oracle Service Bus For loop getting out of memory error

I have a business service that is based on a JCA adapter to fetch an undertimed amout of records from a database. I then need to upload those to another system using a webservice designed by an external source. This web service will only accept upto to x amount of records.
The process:
for each object in the Jca Response
      Insert object into Service callout Request body
      if object index = number of objects in jca response or object index = next batch index
           Invoke service callout
           Append service callout Response to a total response object (xquery transform)
           increase next batch index by Batch size
           reset service callout to empty body
       endif
end for
replace body with total response object.
If I use the data set that only has 5 records and use a batch size of 2 the process works fine.
If I use a data set with 89 records and a batch size of 2 I get the below out of memory error after about 10 service callouts
the quantity of data in the objects is pretty small, less than 1kB for each JCA Object

It appears to be the service callout that is the problem (it calls another OSB service that logins and performs the data upload to the External service) because If I change the batch size up to 100 the loop will load all the 89 records into the callout request and execute it fine. If I have a small batch size then I run out of memory.
Is there some settings I need to change? Is there a better way in OSB (less memory intensive than service callout in a for loop)?
Thanks.

Hey guys I am wondering whether you configure or allocated memory before you started your installation???? That should be in /etc just vi system as root of course and look for the line *To set variables in Unix
after the set maxuser=XX
add the folowing
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_sshmseg=10
set semsys:seminfo_semmni=100
set semsys:seminfo_semmsl=100
set semsys:seminfo_semmns=430
set semsys:seminfo_semopm=100
set semsys:seminfo_semvmx=100
and reboot you server then your installation won't hung this is the setting of my oracle 817 on Sun box
PS Take special care with set semsys:seminfo_semmns=430 if you are gona have more tha 200 process then do some calculation

Why do I get a Track out of memory error while running open loop frequency response?

MatrixX Build 61mx1411: I get a "Track out of memory" error when I run the Open Loop Frequency Response from the MatrixX pull down tools. What can I do to prevent this? We are running on an HP B1000 with 768 MB of RAM under HP-UX 10.2.

In the old days of Mx say Version 5 and prior the user actually selected the amount of memory that would be allocated. Depending on the size of the model etc. you would have to allocate memory. In version 6.0 and going forward there is no need for the user to manually allocate the memory.
Build {rstack=50000,istack=200000,sstack=50000,cstack=500 000}
If this is a command in a script file that you are running and the error is resulting from that then I would try commenting out everything after the letter d in the word build and then starting it back up.
i.e. only use Build
I don't believe that there is a way to manually allocate the initial SystemBuild Stack size.
I believe initially the stack size is set to 10010.
However, one way
you can manually set the initial SystemBuild stack size,is to create a large StateSpace as soon as you start up SystemBuild. This will prevent piece-meal reallocs while using SystemBuild.
You can created a new SuperBlock in SystemBuild and then drop down a StateSpace Block with 199 inputs and 199 Outputs and 1 State and entered ones(200,200)as the StateSpace Matrix without any problems. This would resize this internal stack to at least 40000.
You really should not have to do this but if that helps then you might think about doing this in your startup.ms file you could use SBA or load the file then you could delete the superblock and begin working.
"Bob" gave me this little tid bit.
Please let me know if any of this is of use.

Spooling to Text File - 30 million records - Getting Out of Memory Error

Hi All,
I have an extremely large oracle table that I need to spool to a .txt file. The table has approximately 30 million records. I'm using Toad For Oracle version 10.5 and I'm on Oracle 10g. I've tried running the following spool command a few times and it keeps crashing...I'm getting a "Out of Memory" error in my Toad window when I execute it as a script. Here's the code:
Spool on
set heading off
SET PAGESIZE 0
SET TRIMSPOOL ON
SET LINESIZE 100
set feedback off
set echo off
set termout off
Spool "C:\spooledtext.txt"
select
column1
from test_table
order by
column2,
column1
Spool off;
An ideas as to how I can get this query to spool to a text file without crashing and running out of memory?
Thanks

use sqlplus.
Or select smaller chunks and use copy to concat them afterwards.

Getting HeapDump on out of memory error when executing method through JNI

I have a C++ code that executes a method inside the jvm through the JNI.
I have a memory leak in my java code that results an out of memory error, this exception is caught in my C++ code and as a result the heap dump is not created on the disk.
I am running the jvm with
-XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=C:\x.hprof
Any suggestions?
Thanks

I'll rephrase it then.
I have a java class named PbsExecuter and one static method in it ExecuteCommand.
I am calling this method through JNI (using CallStaticObjectMethod). sometimes this method causes the jvm to throw OutOfMemoryError and I would like to get a heap dump on the disk when this happens in order to locate my memory leak.
I've started the jvm with JNI_CreateJavaVM and I've put two options inside the JavaVMInitArgs that is used to create the Jvm. -XX:+HeapDumpOnOutOfMemoryError and -XX:HeapDumpPath=C:\x.hprof
which supposed to create a heap dump on the disk when OutOfMemoryError occurs.
Normally if I would execute normal java code, when this exception would occur and I wouldn't catch it the Jvm would crash and the heap dump would be created on the disk.
Since I need to handle errors in my C++ code I am use ExceptionOccured() and extracts the exception message from the exception it self and write it.
For some reason when I execute this method through JNI it doesn't create the dump.

Keep getting Out of Memory error on InDesign CC 2014

I work with 5 documents on a daily basis that can have over 150 images imported each. When I try to move around the document, it either freezes up and the wheel keeps turning or it comes up with an Out of Memory error message and locks up. It also will just quit.
I had seen somewhere about being able to "assign" a certain amount of memory to the software using the "get info" panel, but I can't find any reference to memory on the "get info" panel.
Any help would be greatly appreciated.

I inherited the file from a previous employee and they had lots of embedded files. I am slowly replacing them with linked as they are updated. Are linked or embedded better?

Photoshop keeps on getting out of memory error after installing Premier Pro

I just upgrade my CS to CC. Yesterday I installed Photoshop and did my work without any problem but today after installing Premier and After Effect, I keep on getting out of memory error when I'm working even though I don't have any other application running accept photoshop alone. The file I'm working on is a small file, iphone plus size interface. Basically I can open the file, add blur effect and try to type text I will get photoshop telling me that my system is out of memory. Restarting photoshop give the same problem, restarting my computer give the same problem, ie do one thing and next will give memory not enough.
I don't think my system is slow as it is workstation with dual processor and 12 gig of ram, windows 7 64bits 1gb dedicated memory for graphic card.
I uninstall Premier and After Effect and suddenly the problem go away. Photoshop work as per normal. I didn't have the time to reinstall premier again but will try to do it tonight or tomorrow
Anyone experience such problem before?

When you get that error leaver the error showing and use something the can show you how much free disk space there is left on Photoshop scratch disk. It may be a problem with scratch storage space not ram storage space. I see Photoshop use much more scratch space the ram. I have seen Photoshop using less than 10GB of ram on my machine leaving 30GB of free ram on my system unused while using over 100GB of scratch space.

Hello All,
I am getting 'Out of memory' error while opening the file. I have tried several versions of Adobe 7.0,9.0,X1.
Also, it is creating issue to convert PDF into TIFF. Please provide the solution ASAP.

I am using Adobe reader XI. When i open PDF it gives "OUT of memory" error after scrolling PDF gives another alert "Insufficient data for an image". after clicking both alerts it loads full data of PDF. It is not happening with all PDFs. couple of PDFs are facing this issue. Because of this error my software is not able to print these PDFS into TIFF. My OS in window7*64. I tried it on win2012R2 and XP. Same issue is generating there.
It has become critical issue for my production.

Why do I get out of memory errors when 10GB memory is free?

I am on HP UNIX 64bit 11.23 titanium, running Oracle 10.2.0.3. . My server has 24GB memory and of that 10GB is free (as seen in glance). When I doing oracle exp or rman commands, I get:
ORA-04030: out of process memory when trying to allocate 1049112 bytes (KSFQ heap,KSFQ Buffers)
I checked both rman and exp are 64bit executables, so they should be able to access all the memory on the system.

I have just one parameter in init.ora sga_target which controls everything in SGA. hw two instance I was reporting porblem have sga_target of 256M and 192M, Problems happen off and on, but 9 to 10GN free memory is alwyas available on server.
Her is more information on the problem:
1.     I do not think problem is with ulimit, but something is definitely not set correctly. Ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 4194300
stack(kbytes) 131072
memory(kbytes) unlimited
coredump(blocks) 4194303
parameters are reasonable.
2.     I have 10GB free memory. I run simple java command
Java
it works.
3.     Now I increase memory for sga_target for one of my Oracle instance from 256M to 512M. I only hav eon eparameter sga_traget which controls everything in SGA. There are many other Oracle instances on the server. My Oracle instance starts without problems.
4.     I now run java, it gives me:
Out of memory error, so Oracle has exhausted some memory (probably shared memory) which is needed by java. I still have 9-10GB memory on my server, so why java is not using this memory.
5.     After iOracle instance starts, off and on Oracle backups fail with ORA- error (not enough memory) I reported earlier.
I hope HP engineers can figure this out.

OK - the problem you describe is definitely what's giving you grief.
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?
