Steve, why is xmldom.writetoclob so slow ??

I am using xmldom.writetoclob, which is OK when transfering small ( < 1MG ) documents to a CLOB, but as the documetns get bigger it is very slow..
It takes 15 minutes to transfer a 5MB document to a clob using xmldom.writetoclob.
Anything I should be doing to see better results ?
Thanks.
I am using the PL/SQL parser

what is your java_pool_size?

To : Oracle Team.. xmldom.writetoclob is too slow

HI;
I had Oracle 8.1.6, Used the xmldom package a lot to manipulate and create xml documents ( all sizes ). then I used xmldom.writetoclob which it was giving a GREAT performance.
I UPGRADED ti Oracle 8.1.7 and xmldom.writetoclob is TOO SLOW now, I have the same settings ( java_pool_size, share_pool, etc)
What changed from 8.1.6 to 8.1.7 ??
Why xmldom.writetoclob is so much slower in 8.1.7 ??
when tranfering a 300 KB document with 8.1.6 it used to take 30 seconds, no with 8.1.7 IT TAKES 2-1/2 minutes ?????
WHY ? ? ? ? ?
Tahnks for any information..

My guess is that you are creating a clob with cached set to false
e.g
dbms_lob.createtemporary(v_myclob,false);
When set to false any time the clob is written to the characters are written to the disk. causing it to be slow.
try
dbms_lob.createtemporary(v_myclob,true);
I had the same problem. This speeds it up significantly

Xmldom.writetoclob hanging forever when writing a domnode to a temp clob

Hi
Wondering has anyone come across anything similar (or know a work around)
1. Basically the the procedure below loads an XML file. (OK)
2. Removes reference to external dtd, ref was causing and error (OK)
3. Parses the XML (OK)
4. Gets a list of the "item" tags (OK) - should be up to 500 item elements in XML
5. Loops on all elements
a. writes node to temp clob *(PROBLEM HERE)*
b. Creates xmltype from clob (OK)
c. transforms xmltype and assigns to another xmltype (OK)
d. inserts new xmltype (OK)
This procedure is used by a threaded os java app to load thousands of files to db.
It works fine 99% of the time but for some files the procedure is hanging at (5.a : write domnode to clob using xmldom.writetoclob)
I am absolutely sure the problem is due to the characters in the domnode as all files that have hung on processing contain these bizarre characters,
the db character set is Unicode AL32UTF8 so it should be able to handle almost anything, saying that, if the it is a prob with the characters then why does
the loadclobfromfile procedure succeed.
Developed on Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit
I have no prob rejecting node and continue processing but procedure just hangs and i have to kill the thread on the os.
Is there a way to
1. Test for invalid AL32UTF8 chars and skip on error.
or
2. Get around the xmldom.writetoclob procedure and create an xmltype from the xmldom.domnode (i tried to convert domnode -> domdocument -> xmltype, no joy)
or
Open to suggestions

2. Get around the xmldom.writetoclob procedure and create an xmltype from the xmldom.domnode (i tried to convert domnode -> domdocument -> xmltype, no joy) Which version of Oracle (4 digits)?
Also look in the FAQ in the upper right for how to use the tag to wrap PL/SQL to retain formatting to make it easier for all to read.

Problem with special characters and xmldom.writetoclob

Hi!
I have a problem with oracle parser in pl/sql.
My situation:
i have a clob with valid xml with for example decoded characters:
(spaces between & and # are for good representing characters by browser - in really there is no spaces)
<xml>
<any><![CDATA[ & #187; ]]> text <![CDATA[ & #187; ]]></any>
</xml>
i read this xml from clob, parse it and put into another clob by using
xmldom.writetoclob procedure.
And in second clob i have"
<xml>
<any>& #38;#187; text & #38;#187; </any>
</xml>
(ampersand is representing as & #38; !) Why there is not the cdata sections ?
Why the value of these sections changed?
Any ideas? I'm using newset xdk (9202) in 8.1.7.3 database.
Please help!

Hi John,
According to your description, my understanding is that the Author showed incorrect character in SharePoint 2013 search result page.
I tested the same scenario per your post in my environment, and the Müller showed correctly in SharePoint search result page.
I recommend to reset the index in Search Service Application and run a full crawl to see if the issue still occurs.
Best regards.
Thanks

Using xmldom.writeToClob to update xml clob corrupts clob

We are storing an xml document in a clob field in the db. As part of a data check we need to parse the xml and possibly remove a node. I can do that, and check the results using 'xmldom.writeToBuffer'.
When I try to write the data back to the db using 'xmldom.writeToClob' I get strange results. Data seems to be appended to the end of the clob and contains chr(13) characters at the end of each line.
Also does anyone know if the existence of whitespace in the xml clob would cause a parse/search to be slower?
I am new to xml and might be missing something fairly basic in the following code. Thanks in advance for any help.
Here is some of the code:
doc xmldom.DOMDocument;
curNode xmldom.DOMNode;
parentNode xmldom.DOMNode;
theNodeList xmldom.DOMNodeList;
str varchar2(4000);
begin
-- open xml_rec cursor (xml is the clob field opened for update)
-- Loop through all item elements
theNodeList := xmldom.getElementsByTagName(doc, 'item');
for m in 0..xmldom.getLength(theNodeList)-1 loop
curNode := xmldom.item(theNodeList,m);
--perform a check and possibly delete the current node
parentNode := xmldom.getParentNode(curNode);
parentNode := xmldom.removechild(parentNode, curNode);
xmldom.writeToBuffer(doc, str);
--I check the results here and everything looks good
xmldom.writeToClob(doc, xml_rec.xml);
--When I check the clob the data is incorrect.
null

The next cod is a sample of the implementation xmldom.writeToClob used xmldom.DOMNode in the parameter of input.
DECLARE
XMLOut CLOB := EMPTY_CLOB();
XMLIn Varchar2(2000);
XSLPath Varchar2(2000);
BEGIN
DBMS_LOB.CREATETEMPORARY(XMLOut,TRUE); -- Give permit
DBMS_LOB.OPEN (XMLOut, DBMS_LOB.LOB_READWRITE); --open the file of read and write
XSLPath := '/users/gcardona/plantillas/report.xsl';

GE_BSXMLCONVERT.addElement();
XMLIn := GE_BSXMLCONVERT.toXML();
XSLTranform(XMLIn, XSLPath, XMLOut);--XMLOut is a variable in out in the procedure,
--here is where is return the file XML Process
insert into in_prueba (ID,XML_CLOB) values (200, XMLOut);

Why is my Macbook so slow to open?

Why is my MacBook so slow to start up? I've recently cleared more space on the start-up disk (currently has 49GB of the 74GB capacity), but it still takes about 2 minutes to start up from cold. Any suggestions?

Hi Stevie,
several thing could caused that, like a lot of application that need to be opened during start up, your default boot up destination is not your internal HD (so it will try to look to optical first, "clogged HD", etc.
Try to optimize and repair permission in your macbook HD using ONYX or MAcHelpMate,
http://www.apple.com/downloads/macosx/systemdiskutilities/onyx.html
http://www.apple.com/downloads/macosx/systemdiskutilities/machelpmate.html
Try to reset PRAM:
http://docs.info.apple.com/article.html?artnum=2238
Open system preference: account : Login item and uncheck application that you don't want to start automatically.
Good Luck

Xmldom.writeToClob error. [URGENT]

Any idea why I get the following error when I call:
xmldom.writeToClob(root, xml_out);
ORA-20000: An internal error has occurred: CLOB to write to can not be null ORA-06512: at "XML.XMLDOM", line 37 ORA-06512: at "XML.XMLDOM", line 358 ORA-06512: at line 131
'xml_out' is initialised with null, but 'root' have some nodes and elements, but no text nodes. I do not get this error if I use
xmldom.writeToBuffer(root, v_xml);

Why is my ipad2 really slow after updating to IOS 6.1.2

Why is my ipad2 really slow after updating to IOS 6.1.2

Try this.
Quit all apps completely and reboot the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

UTL_FILE comes as part of the database, you shouldn't have to install it, and you most certainly shouldn't install it as SCOTT. System packages should be installed using a system user such as sys.
Firstly, I would suggest dropping the UTL_FILE package from your scott schema and then logging on as sys and granting execute permission on UTL_FILE to the scott user.
Secondly...
The UTL_FILE_DIR parameter has been deprecated by oracle in favour of direcory objects because of it's security problems.
The correct thing to do is to create a directory object e.g.:
CREATE OR REPLACE DIRECTORY mydir AS 'c:\myfiles';Note: This does not create the directory on the file system. You have to do that yourself and ensure that oracle has permission to read/write to that file system directory.
Then, grant permission to the users who require access e.g....
GRANT READ,WRITE ON DIRECTORY mydir TO myuser;Then use that directory object inside your FOPEN statement e.g.
fh := UTL_FILE.FOPEN('MYDIR', 'myfile.txt', 'r');Note: You MUST specify the directory object name in quotes and in UPPER case for this to work as it is a string that is referring to a database object name which will have been stored in uppercase by default.

Why is the refresh rate slower in lab mode? photoshop cc 2014

hi
why is the refresh rate slower in lab mode?
for example i load an image , rgb , ad an adjustament layer -> curve and i start to play with curve -> the refresh is instantaneous (i mean the image become more dark or lighter instantaneous )
but if i load an image -> conver in lab mode , the refresh rate is slower
i tried cs6 too, same behavior
ps how can i have an email to notify me that someone answer to this discussion?

Why is Bridge CC so slow?

I'm trying to figure out a way to diagnose why Bridge CC is so slow. I regularly use programs like Photoshop, Lightroom and Premiere and don't notice any kind of inapropriate lag or delays at all. However, when working in Bridge it just feels slow. Opening menus occasionally just hangs for seconds on end before dropping down. Thumnails from a gallery I've previously viewed can take upwards of 10 seconds to appear after opening the software. But the most noticeable and repeatable issue comes when trying to select more then one image files. CTR-Clicking a second (or however many additional files) can take anywhere from 5-8 seconds to happen. This, more then anything else, is making bridge unusable.
What should I do?

I just bought a new computer with with Windows 8.1 and plenty of all the hardware that make Adobe CC work great. Unfortunately Bridge had the sluggish slow response that seems to be haunting many people. I read through the adobe support and forums and found a number of good places to look but nothing that outlined a working solution for me. I tried all this http://helpx.adobe.com/bridge/kb/troubleshoot-errors-freezes-bridge-windows.html and nothing worked. I was facinated to find people were able to create new account and found the unresponsiveness went away. I also payed close attention to the fact that network drives might cause problems. Not being familiar enough with Windows 8.1 I looked for traditional XP network drives and found that wasn't the problem. But yesterday I realized I have "Libraries" that point to my windows 8.1 laptop and one that pointed to SkyDrive. The settings transfered to my new PC when I used the same login information from my laptop. So I went in to the libraries and removed all the links that went to my laptop and skydrive and Bridge worked perfectly as would be expected on a new PC. So check your libraries. This might also explain why some people found that a new account solved the problem.
Open the "desktop"
Open "file explorer"
Go to the "view" tab
Click on "navigation pane" in the ribbon
Select "show libraries"
Expand "Libraries" in the folder view
Check the path to every folder in the list
Right-click and choose "remove location from library" if anything points to another computer or SkyDrive
Obviously I can't say it's everyone's problem, but it worked for me. I hope it helps someone. Good luck everyone.

Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

Why is my mac so slow i have cleansed and cleaned it is a 2010 mac mini i5 but it runs like a 20 year old pc i have only had it for a few months and it was straight out of the box

I'm thinking that you have a > Mac mini (Mid 2011) - Technical Specifications because the 2010 model's only have Core 2 Duo processors and the 2011 had the first i5 processor.
2 GB of RAM is the minimum requirement for Mountain Lion, but it's hardly enough to really enjoy doing anything else.
see > Memory and Free Installation Guides for Apple Mac Mini
Plus I don't have any problems running Mountain Lion and a load of App's on my 2010 Mac Mini with 8GB of RAM.

Why is the library so slow to upload to iCloud?

Hi there,
After a bit of hassle getting Photos to accept all my pictures from iPhoto I thought it was all fixed and ready to go to cloud storage so that I can have the same library on iMac, Macbook Pro and my iPhone.
My photo library isn't that big, about 40Gb (4607 items) but it seems to be taking forever to upload to iCloud.
My broadband speed isn't great (Around 6.5 MBPS download and around 0.7MBPS upload) but after several days my Photo library states that it is uploading 4570 items. When i try to run photos from my macbook there are only a few photos on there.
At this rate I'll probably die of old age before all the photos are in the cloud and bounced back onto my macbook & phone.
Other than slow broadband speed and apple being busy with people like me uploading, are there any other reasons why this is taking so much time? Bad settings anywhere?
As another example my iMac has been on for a couple of hours today and the Activity monitor states that 887.2MB has been sent to the cloud. That's pretty damm slow isn't it?
Thanks

Why is my finder so slow to update. For example, if I
download a file (using Safari), I can't find it on
the desktop. If I use Find at the Finder level, it
says it's there, but I can't see it.
Same thing happens with Mail, trying to attach a PDF
I just made. Mail can't see it.
I love all the wondrous glitz of OSX, but wouldn't it
be nice if it could do the basic stuff as well as
System 6? At the rate Apple's going, we'll probably
get a breathless announcement about a spanking-new OS
called Snail, which doesn't do anything but look
pretty.
Stu,
Did you ever get an answer to this? My finder is pathetically slow to update, a minor irritation a dozen times a day. System 9 never had this problem. Is there a way to get my expensive computer to do this simple task? Is there any news on this?
thanks,

Potential problem with XMLDOM.writeToClob()

I'm really hoping that someone can help me with this. Last fall, wrote some code that used XMLDOM to build a document and send it to a web service. I remember having problems with WriteToBuffer and WriteToClob during my development efforts, which I thought were successfully resolved. Now it looks like the problem may be occurring at a client who recently upgraded to use this code. I can't get this to fail in-house, so I can't do much debugging on it. So I'm hoping that someone else has come across a problem like this and remembers what they did to fix it.
Basically, what happened was, WriteToClob (or sometimes WriteTuBuffer) didn't return anything, even though the DOM document was not empty. I remember going back and forth between WriteToBuffer and WriteToClob, trying to get it resolved. But I don't remember specifically finding any "magic bullet". Here's what I currently have in the code:
DBMS_LOB.createtemporary (v_source_data, TRUE);
DBMS_LOB.OPEN (v_source_data, DBMS_LOB.lob_readwrite);
xmldom.writetoclob (v_main_doc, v_source_data);
DBMS_LOB.CLOSE (v_source_data);
Has anyone had a similar problem, and remember what the fix was? I'm also not sure that the Open/Close calls are necessary. Or what TRUE means on CreateTemporary (aside from some generic comment about "buffer cache" without telling me what a buffer cache is).

Steve, why is xmldom.writetoclob so slow ??
