Hi,
Do you mean to say that your ECC 6.0 system is running on Windows XP System ?
How come ???
Please chek with your OS Version.
Also check your JDK Version.
Please use Sun J2SE 1.4.2_11 SDK and above. Please also do not use J2SE 5.0.
For details please refer : SAP Note 716604 - Access to Sun J2SE and recommended J2SE options.
May be you could also refer SAP Note 940893 - Analysis of errors within the startup of J2EE Engine 6.40.

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.

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.

R 6018 unexpected heap error when generating a form in Designer

Has anyone else encountered it before with forms?

You put the question to wrong forum. If it is regarding to Oracle Forms, then post to Oracle Forms forum. If it is regarding to Oracle Designer, then post to Designer Forum. This is the forum for Oracle Reports.

Heap Error during Windows OCIEnvCreate() call

During a call to:
OCIEnvCreate(&m_handles.m_pOCIEnv,
                         OCI_THREADED | OCI_OBJECT,
                         NULL,
                         NULL, NULL, NULL,
                         0, (dvoid **)0);
A crash occurs which reports the following in the MSVC 2005 debug output window:
HEAP[AutoTest.EnvironmentPkg.DatabaseConnectionManager.exe]: Invalid Address specified to RtlFreeHeap( 00150000, 0015ED80 )
Windows has triggered a breakpoint in AutoTest.EnvironmentPkg.DatabaseConnectionManager.exe.
This may be due to a corruption of the heap, and indicates a bug in AutoTest.EnvironmentPkg.DatabaseConnectionManager.exe or any of the DLLs it has loaded.
We are using version 10.2.0.3 of the Oracle Basic Lite client on Windows XP, called via SQLAPI++.
I have verified that the memory we allocate is not being corrupted before this call. Using Compuware's Boundschecker VS add-in, I've verified that the heap error is in a memory range allocated by oraociicus10.dll. Since the OCIEnvCreate call is the first time that oraociicus10.dll allocates memory (i.e. my code doesn't have a chance to trample Oracle's data structures), there's a good chance IMO that it's an internal Oracle problem.
Boundschecker reports errors such as:
Pointer Error: When calling LocalFree, pointer 0x03A60A5C is not at the beginning of the block 0x03A60998 (65536) allocated by LocalAlloc.
These errors are reported in a Debug build; the same kind of error happens during a Release build.
According to a previous thread, a special release of the OCCI interface DLLs was needed to fix MSVC 2005 compatibility issues like this one. (See Debug in Visual Studio 2005 (vs8) ? )
I've posted looking for any such release for OCI DLLs, but haven't found any yet ( MSVC 2005 compatible OCI DLLs? )
My questions:
1. Could this be a compatibility problem between the OCI DLLs and MSVC 2005? and
2. If not, what could the problem be?
Thanks in advance for your help.

Are you using the oracle thin client ...?? Try using the full client install.
Is it working with OCI_DEFAULT or OCI_THREADED alone ???
Please note the following points in WINDOWS Platform.;
1)Try always a fresh installation for Oracle and VS products.Preferably a clean install of the OS.
2)If don't want to remove OS , do a clean UNINSTALL (This should include a complete clean up in the Registry and file systems).
3)Always reboot the system before and after installations and try your code.
If the above sequences are followed most of the DLL/LIB problem are solved for me.

Out of HEAP error installing JSE8.1 beta

My installatio fails with an out of Heap error - any idea on how to overcome this problem ? There don't seem to be any switches on the installer for setting up a bigger heap.
Using JDK1.6.0 beta 2

I'd suggest the following workaround:
1) Run the installer with -is:extract parameterб e.g.
./jstudio_ent81-beta-linux.sh -is:extractThis will extract the installer jar file either in the current directory, or in a subdirectory named isXXXXXXXXXXX (where X is a number).
2) Then run the jar file, setting the heap space, etc:
java -Xmx1024m -jar jstudio_ent81-beta-linux.jar

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

Heap error when trying to map a CLOB element to an object using toplink

I ran a SQl query which retrieves a clob element of 40MB size. The application retrieves the CLOB and probably stores in the temporary buffer. And when the CLOB is retrieved from the buffer to map it to the actual business object, we are getting a heap dump error. The error is as follows:
kghalo bad size 0x05063398

We also tried increasing the heap size settings of the JVM. But no luck.
Any suggestions would be appreciated.
Thanks

A similar issue was fixed in ODP.NET 92040 beta release. Please give it a try.

Heap Error: Invalid Address specified to RtlValidateheap

I have an OCCI program that connect to the Oracle database using Oracle\oraclient\9.2.0 and executes a query. I'm able to connect return a result set and actually display contents from the first row.
However, as soon as I attempt to access the second row I get a heap error - - invalid address specified to RtlValidateHeap.
I've seen other post where changing the type of run-time library under the Code Generation options of the compiler made a difference. Here, I've tried them all: /MTd, /MLd, /MDd but to no avail.
I'm using Visual C++ 6.0 and linking in occi library oraocci9.lib.
The line of code that's getting the error is the following:
while ( resultSet->next () )
no problem in getting the first row. Its the second next that dies.
Any help would be appreciated.

When I build the App with a RELEASE build instead of a DEBUG build this problem goes away.
Apparently there is a bug in the oraocci9.lib regarding allocating on the Heap for DEBUG builds.
While reading the other post on this forum I've discovered that I need the 9.2.04 version of the oraocci9.lib and oraocci9.dll that have been linked with MSVCRTD.dll, which is required to use in Debug mode for MSVC.
It's unfortunate that this bug is not documented in the OCCI Programmer's manual that is available online. I could have saved myself a lot of time.
Where can I find the most up-to-date patches for Oracle 9i?
Any help would be appreciated. Thanks.
Are these files available as standalone downloads on the Oracle web site? I haven't seen them. I don't want to download the entire database if I can avoid it. I just need the upgraded version of oraocci9.lib.

Internal heap ERROR 17177

Hi All,
how to slove this problem.
The main xyz switch has some pro* c code in the database module which has been compiled against 8.1.7.4 Oracle client libraries. So far, we have been running xyz against 8.1.7.0 database but now we are looking forward to upgrading our database to 10g.When we try to connect to 10 g using oracle 8.1.7.4 client, we face core dump issues + oracle error messages thrown on the screen. Sqlplus calls seem to work fine but the path we take using libclntsh.sl.8.0 seem to fail.
The following is the error:
