XMLTRANSFORM Too large stylesheet - code buffer overflow issue
Hi All,
My question is related to MSWordML generation from PLSQL stored procedure.
1. I have table, containing XSLT stylesheets for different documents
2. PLSQL stored procedure is generating dynamic content depending on some params and at the end I'm using
SELECT XMLTRANSFORM(XMLTYPE.createxml(db_data_clob), XMLTYPE.createxml(x.xslt_clob)).GetClobVal()
INTO res
FROM msword_ml_data x
WHERE x.report_id = rep_id_variable;
where : x.xslt_clob -> column, containing XSLT CLOB
db_data_clob -> dynamic content CLOB
res -> CLOB result
All this was working fine on Oracle11gR1, but I had to reinstall database and I said why not install Oracle11gR2 ...
Guess what. Stored procedure is raising exception when using XMLTRANSFORM :
Exception : : ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00004: internal error "Too large stylesheet - code buffer overflow"
Google says nothing about it. I don't recall setting some special DB property in Oracle11gR1.
Has anyone encountered this ?
I haven't changed procedure nor table.
I'm using exactly the same XSLT's from Java code and they are working just fine, so they are not the reason. My guess is that something in Oracle11gR2 related to XML processing is changed.
If anyone could help, thanks in advance
For those who are interested.
I have logged a service request and it turned out that this is is a bug in Oracle 11gR2.
"The limitation on the style sheet is not exactly a size limit but a limitation on the number of style sheet instructions and depends on the way the style sheet has been written. This is a C based parser limitation"
Anyway, the workaround is to create Java stored procedure and do transformation from there.

Imp-00020 long column too large for column buffer size (22)
Hi friends,
I have exported (through Conventional path) a complete schema from Oracle 7 (Sco unix patform).
Then transferred the export file to a laptop(window platform) from unix server.
And tried to import this file into Oracle10.2. on windows XP.
(Database Configuration of Oracle 10g is
User tablespace 2 GB
Temp tablespace 30 Mb
The rollback segment of 15 mb each
undo tablespace of 200 MB
SGA 160MB
PAGA 16MB)
All the tables imported success fully except 3 tables which are having AROUND 1 million rows each.
The error message comes during import are as following for these 3 tables
imp-00020 long column too large for column buffer size (22)
imp-00020 long column too large for column buffer size(7)
The main point here is in all the 3 tables there is no long column/timestamp column (only varchar/number columns are there).
For solving the problem I tried following options
1.Incresed the buffer size upto 20480000/30720000.
2.Commit=Y Indexes=N (in this case does not import complete tables).
3.first export table structures only and then Data.
4.Created table manually and tried to import the tables.
but all efforts got failed.
still getting the same errors.
Can some one help me on this issue ?
I will be grateful to all of you.

Edited by: user462250 on Oct 14, 2009 1:57 AMThanks, but this note is for older releases, 7.3 to 8.0...
In my case both export and import were made on a 11.2 database.
I didn't use datapump because we use the same processes for different releases of Oracle, some of them do not comtemplate datapump. By the way, shouldn't EXP / IMP work anyway? -
Screen too large for internal buffer
Hi,
2 days ago I have an issue when I execute "crontab -e" with my terminal maximized. The error say "Screen too large for internal buffer" and the term crash. But when the term isn't maximized the command works fine. I tried with teminal (XFCE), Konsole, rxvt... My screen resolution is 1680x1050. With visudo command I have the same issue.
¿Anybody have this problem too?
Many thanks

HELP!!! Error "code too large"
Hello, I am working on a program that has become very large... and apparently it is too large now...
When I try to compile the program it generates an error, "code too large", the code has exceeded 10000 lines and now I dont know what to do. Anyone that has any ideas? Thankful for any response...Let's say, for instance, that I wnat to initialize an array instance variable that will contain 7462 integer values in my constructor, just as an example. I'm not really sure if this exceeds the maximum size for a java array, but if it does that would be just as useless a restriction as this "code too large" thing. If I write huge code that means I need huge code. [ goes to write program in C, which would be my advice here. :) ]

Versions (databases, exp, imp), commands and parameters used - copy&paste, relevant part of logs - copy&paste, describe table, etc.
Some background, like what's the purpose, did this work before, what has changed, etc.
Also you might check the suggested action for the error code per documentation:

Requested buffer too large - but data is already in memory
Hello all,
I am writing a program that generates sound and then uses the Java Sound API to play it back over the speakers. Until recently, using clips have not led to any problems. On two computers I can play the sound without a hitch. However, on the newest computer (and also with the largest specs and especially more RAM), I am getting an error while trying to play back the sound. The exception that is thrown is:
javax.sound.sampled.LineUnavailableException: Failed to allocate clip data: Requested buffer too large.
I find this odd because the buffer already exists in memory: I don't have to read in a .wav file or anything because I am creating the audio during the course of my program's execution (this is also why I use Clips instead of streaming - the values are saved as doubles during the calculations and then converted into a byte array, which is the buffer that is used in the clip.open() method call). It has no problems allocating the double array, the byte array, or populating the byte array. It is only thrown during clip.open() call. I also find it strange that it would work on two other computers, both of which have less RAM (it runs fine on a machine with 512MB and 2GB of RAM, both XP 32-bit). The only difference is that the computer with the issue is running Windows 7 (the RTM build), 64-bit with 6GB of RAM. I am running it through Netbeans 6.7.1 with memory options set to use up to 512MB - but it's never gone up that far before. And I've checked the size of the buffer on all three computers and they are all the same.
Does anyone know what the issue could be or how to resolve it? I am using JDK6 if that matters. Thank you for your time.
Edited by: Sengin on Sep 18, 2009 9:40 PMThanks for your answer. I'll try that.
I figured it had something to do with Windows 7 since it technically hasn't been released yet (however I have the RTM version thanks to a group at my univeristy in cahoots with Microsoft which allows some students to get various Microsoft products for $12).
Edit: I just changed the Clip to a SourceDataLine (and the few other necessary changes like changing the way the DataLine.Info object was created) and wrote the whole buffer into it, drained the line and then closed it. It works fine. I'll mark the question as answered, however that may not be the "correct" answer (perhaps it does have something to do with Windows 7 and not being completely tested yet). Thanks.

Hi,
I am facing the problem of code too large in EP6 SP9 version and EP6 SP2 version. Is there a way to solve this problem.
Is this problem solved in the latest version EP6 SP12.
Please help me out in this regard.
Thanks and Regards
Padmaja.PI had this same problem, JSP code generated is too big. I had the problem on SP11. OSS Note 820282 tells you to change the jsp.bigmode.delimit.size = 10000. This did not work for me. I opened an OSS note about it. They told me to set it to "1". After that, it worked. I took them 3 weeks to tell me to set it to "1", in the meantime, I changed my <formlayout> tags to standard HTML, to get around the problem. I don't know if SP12 has fixed this issues or not.

Oracle JSP Exception code too large for try block
My jsp is exceeding the memory limit (64KB for Oracle 10g App server i think its the JVM limit),
so it is throwing exception ,code too large for try block,how to over come this,I cant minimize the use of logic tags because it is business requirement.please help me out.I think you need to give a value to the attribute buffer in the <%@ page%> directive to solve the problem.
There will not be any need of going for pagination then.
buffer="none | 8kb | sizekb"The buffer size in kilobytes used by the out object to handle output sent from the compiled JSP page to the client Web browser. The default value is 8kb. If you specify a buffer size, the output is buffered with at least the size you specified.

Playing a large Clip and "Requested buffer too large" exception
Hi All.
Through JavaSound, I am trying to reproduce a WAV audio file that I create within my application. Also the recording/acquisition of the audio file is performed through JavaSound.
The WAV audio file that I am trying to play has the following features:
- 44 Khz, 8-bit, mono
- Length = 1min 36sec
- File size = 4.04 MB
Here is a fragment of my code:
// Get the input stream from the input audio file
audioInStream = AudioSystem.getAudioInputStream(inputFile);
AudioFormat audioFormat = audioInStream.getFormat();
// Compute the buffer size (for a 0.25 seconds buffer)
float bufferTime = 0.25F; // 0.25 seconds of buffer
int frameSize = audioFormat.getFrameSize();
float frameRate = audioFormat.getFrameRate(); // frames per second
int numOfBufferedFrames = (int)(frameRate * bufferTime);
int bufferSize = frameSize * numOfBufferedFrames;
// Create the output data line
DataLine.Info sourceDataLineInfo = new DataLine.Info(Clip.class, audioFormat, bufferSize);
sourceClip = (Clip)AudioSystem.getLine(sourceDataLineInfo);
sourceClip.addLineListener(this);
// Prepare the output line for playing
sourceClip.open(audioInStream);
// Start playing
sourceClip.start();This code works perfectly fine on Windows (I am testing on a Windows XP Pro 32-bit machine).
On the other side, this code throws the following exception on Mac OS X:
javax.sound.sampled.LineUnavailableException: Failed to allocate clip data: Requested buffer too large.
at com.sun.media.sound.MixerClip.implOpen(MixerClip.java:561)
at com.sun.media.sound.MixerClip.open(MixerClip.java:165)
at com.sun.media.sound.MixerClip.open(MixerClip.java:256)
at mypackage.AudioPlaybackThread.run(AudioPlaybackThread.java:70)
at java.lang.Thread.run(Thread.java:637)The exception is thrown upon the sourceClip.open(audioInStream); call.
Googling around, I discovered that the MixerClip implementation seems to have some inherent buffer size limitation of 1 MB... Isn't it ridiculous?
But why this is working perfectly fine on Windows - even with clips of 4 megabytes -, while not working with larger clips on Mac OS X?
Also, will the following code line influence the size of the buffer used by MixerClip?
DataLine.Info sourceDataLineInfo = new DataLine.Info(Clip.class, audioFormat, bufferSize);I know that I could use a SourceDataLine class, and write() data into it in order to reproduce my long audio clip, but I need support for pausing, seeking audio to a specific position, seeking forward, etc., and using a Clip would be absolutely perfect for this purpose!
Any help or suggestion would be greatly appreciated.

end
ReportingServicesYou'll get this error if the difference between the start and end date is greater that about 68 years due to the "second" DATEDIFF specification. Perhaps the dates are greater than the expected range due to a data quality issue.
Taking the advice from the error message, you could use minutes instead of seconds like the example below the version below. This could still result in the error of the difference is greater than a couple of hundred years, though. You might consider
validating the dates and returning NULL if outside expected limits.

JSPX: code too large for try statement try
I'm migrating an application from Tomcat 5 to OC4J 10.1.3.2 and I'm getting the following error in a JSPX file.
8770
[jsp src:line #:931]
code too large for try statement try {
This isn't an issue in Tomcat because of the way jasper creates the .java file. OC4J creates one really long _jspService method. Is there anything I can do short of rewriting the page to fix this? Let me know if further information is required.I have created bug 6152265 to track this.

How large is too large to eliminate sycn issues
I am new to Captivate and have downloaded the trial version
before I buy it. I have seen many online videos between 10 to 15
minutes lenth i.e., Lynda.com where the producer who created the
files looked to be doing it in full motion recording with narration
at the same time. I have created several projects all from 10 to 15
slides. After they were published the collection of .swf were
between 10 to 20 megs. When I upload them to a server, after half
way through captivate video, the audio and video become out of
sync. I did not recorder all 10 to 15 slides at once. I recorded
about 15 to 30 seconds at a time.
I called Adobe Customer service and the representative said
that my files size was too large, and that was the reason for the
sync issues. Is this common with only with Captivate and are there
better products to be using? The rep suggested that I export the
audio and put it in a program to decrease the file size and import
it back into the slide. I exported the audio and imported the mp3
back into the slide however the published version was still the
same size.
I saw another post where the person suggested recording the
video first and then returning to the slide to record the
voiceover. That seems like it would be more challenging to read a
script and match it to the activity i.e., opening windows, typing
data into fields etc. vs. doing it simultaneously. Is recording the
audio and motion simultaneously a waste of time. Do I have to
record audio at FM radio bit rate which sounds awful?
I have spent several hours and am very frustrated. If any one
could help, that would be appreciated.Hi there,
Thank you for your kind words, please find answers to the
questions you posed below.
quote:
Thank you for your suggestions. When you say daisy chain, do
you mean daisy chain multiple projects or slides? The 30 day trial
version does not allow my to export to Flash 8. Doesexporting to
Flash 8 give an additional opportunity to decrease file size? You
have buttons to the right side of your Training presentation, were
those created in Captivate too?
By daisy-chaining I mean to load one SWF once the previous
one has finished, essentially this is what I am doing in the
example I included. In Adboe Captivate 3 you carry out the
following steps:
1. Choose Edit > Preferences
2. Choose Start and End
3. In Project End options and from the Action menu you choose
Open another project
4. In the text field enter the name of your SWF such as
file2.swf
5. Click OK.
The navigation you see in my example is custom built by one
of our engineers. Essentially we are just using a web page with
some javascript code. You can see the JS code used by simply
viewing the source code in your web browser.
quote:
Full motion and simultaneous narration just seems to be a
quicker solution and the Lynda.com videos can always be paused and
rewound if necessary. What software are the camtasia videos dropped
into to reduce file size and can the Captivate video use the same
software to get the same results?
In some cases full motion recording and voice over can be a
quicker solution. This is the approach I used to take when I worked
for VTC, I would record the voice over and screen action at the
same time. However and bearing in mind that most of the time I was
working with beta software, if the application I was creating
training for crashed then it would be easier to start over and
capture the whole thing again from scratch. Using Adobe Captivate
and capturing in either Audio Recording or Manual recording mode,
because Adobe Captivate only creates the backgrounds as static /
background images I can move the mouse points and adjust things
much more easier than I could with products such as Camtasia.
Personally I much prefer Adobe Captivate because it just
gives me a greater level of flexibility. You can read more about
this via the
Adobe
Case Study
quote:
Back to Flash 8, if a Captivate project were exported into
Flash 8, I assume all the buttons would work and that the
components are exported as well? If so, and I put a preloader on
Flash 8 project, would this eliminate the sync problem? Probably
not because the Captivate has a preloader and that doesn't help.
Exporting to Flash may not solve your problem. Adobe
Captivate does include a number of preloaders which you can find by
carrying out these steps...
1. Choose Edit > Preferences
2. Select the category Start and End
3. Check the option Loading screens
4. Click the "..." button and browse to select one of the
preloaders.
5. Click OK.
quote:
Well it looks like I have to take static images and do a
voice over with Captivate or use CAmtasia and figure out what other
software they use to do the full motion/narration type training
videos.
For effective full motion recording most people will use
Camtasia. Though there are other products such as Hypercam which
you might want to take a look at. If you need something on the Mac
platform then Snapz Pro is a great tool. Just remember that when
working with full motion you are capturing frame by frame and
making dramatic changes to screens (if required) can be a time
consuming process. Adobe Captivate makes this a heck of a lot
easier. To learn more about this take a look at the Captivate 1.01
article I wrote.

Jdeveloper Error: "Code too large"
Hi all,
While running a page in Oracle Jdeveloper 10g, I am getting compilation error “Code too large” on ‘processformrequest’ in controller. I tried the below steps from metalink, but I am still getting the error message.
1. Try to compile your page with the standard "javac" Java compiler instead of the "ojc" Java
compiler, as it generates methods a bit smaller.
2. Change the compiler used by the Embedded OC4J:
2.1) Go to "Tools" -> "Embedded OC4J Server Preferences..."
2.2) Under "Global" select "Java Compiler"
2.3) Select "javac" from the "Compiler" list
2.4) Then under "Bin Directory", point to the location of the javac compiler
(usually in the JDK bin directory).
Please let me know if there is any way to resolve this error.
Thanks in Advance,

Can too large a folder cause issues and effect performace of my Mac Pro
Hi, I have a 180 gb folder filled with important data within my Home folder. This folder has a many subfolders as well. The folder is on my startup drive and where I have Snow Leopard installed. Can too large a folder cause issues with my mac and effect performance? Thanks
another way to ask, would you make better use of, and improve I/O and performance, if you used your other drive bays? yes.
Boot drives with even less than 50% free is probably not a good idea. All depends on whether 200GB is on 1TB or on 500GB drive. And how fragmented free space even.
Lifting, loading and writing or copying 4GB files of course does have an impact, so if you work with 2GB files in CS5....
Having a dedicated type boot drive, media drive (and isolate media and library files) as well as scratch drive is normally done with Mac Pro.
The biggest bang in performance: lean mean SSD boot drive. -
