KEY and KEYREF support in Oracle XML DB

First of all, sorry for my english but I am a spanish researcher who have not been abroad too much :-).
I�m trying to use XML DB to store XML documents that represents UML models and the way I've choosed to map relationships in my schema is using KEY and KEYREFs. The fact is that It seems to me that XML DB does not use them whem it creates the different objects that results on the schema's load. Does XMLDB support the definitons of KEYs and KEYREFs in the schema?? If so, how does it do?? Defining constraints oon the objects created?? I suppose no, because the KEYs and KEYREFs are defined on 'complexTypes' and the Oracle's constraints goes to tables (not to object types).
I'm worling with the next schema:

it says.
I have done several attempts, deleting and including just some of the KEYs/KEYREFs in the schema and it seems to me that the problem is that it let me include so much keys as I want but it fails when the number of KEYREFs that I include increase.
Help!!!
Thanks on advance for spare your time helping us.

Help!!!
Thanks on advance for spare your time helping us.

Looks like known bug 2831302 fixed in (forthcoming) 10g release. In the mean time I would simply comment the key/keyref out of the schema

Nls support with oracle xml parser in java

I'm using The JAXP interface to manipulate xml with xsl. the implementation that I use is Oracle xml parser.
My xml contains a lot of hebrew chars, and in the result stream each char translated into 5-6 chars, which makes the result to be 5-6 times bigger than it suppose to be, and harder for me to debug my application.
The client's browser shows the results well.
How can I make the transformator to transform the hebrew chars to hebrew char istead of longer and not readable string ?

Buy spare keys and plastic support

Hey there
Had an accident and ended up with a loose key ( "Y" ) and its broken plastic support. How do I go about getting a replacement key and support ?
Appreciate your advise
Thanks
Rodney

Sorry to hear about your system problems. I can't help you any but if you do not find help here try posting you question at the L.A. Final Cut Users Group at http://www.lafcpug.org/ These are the guys and gals who edit feature films and large scale videos. I have not posted there but from lurking they seem to be very willing to help and you do not have to be a member to post in their forum.
Surely one of them has heard of this and may have a work around.
Wish I could help more.
Best of luck

FOR ORACLE XML TEAM -- XML TOOLS BUG FIXING POLICY/RESPONSE TIME/RELEASE SCHEDULE

Hi,
The release of Oracle XML tools and utilities by Oracle XML team is a significant milestone and is definitely appreciated. However, as part of a large organization, some factors need to be clarified before using these utilities in production softwares.
I have noticed that XML parsers and other utilities are now coming as part of other softwares like JDeveloper etc. Following are my questions to the Oracle XML team and urgent and prompt reply will be greatly appreciated.
1. What is the XML tools support policy. Is it only OTN? Can we buy support? Are these utilities supported if large organizations have corporate server licenses. I have read at the XML site the XDK is fully and freely supported by Oracle Word Wide support. What does this mean?
2. What is the release schedule for the XML tools?
3. What is the response time?
Once again, your help and prompt reply will be appreciated.
Thanks.

As you noted many of the Oracle XDK components are production. This means that if your company has an Oracle Server Support contract you will get the corresponding level of support for the production XDK components.
If you don't have one, then OTN is your support resource. We will also have standalone support agreements in the future which you can purchase through the Oracle Store. The response time would be the same as for the server.
There is not a specific release schedule for components on OTN as they have different development schedules.

Installing support for Oracle Designer Objects in an existing repository

We have been using SCM to store Forms and other files
for our development work.
Now I want to use Repository Reports in the Repository
Object Navigator, this requires me to install support
for Oracle Designer Objects.
Can I use the Repository Administration Utility and
Install support for Oracle Designer Objects
without effecting the existing repository data?
(I've tried metalink but keep getting TCP Error
while logging the TAR).
Cheers

How can i install oracle designer and prepare the repository at first on my personal my pc

"Oracle xml Database" INVALID

Hi,
when i executed the following query:
SELECT COMP_NAME, STATUS
FROM DBA_SERVER_REGISTRY;
i got all the objects status as VALID except that
"ORACLE XML Database" was INVALID
Can someone help me to make this "ORACLE XML Database" as VALID.
Thanks,
Philip.

HI Frank,
now what i did was i actually ran catpatch.sql and utlrp.sql after i did startup migrate.
and when i did
SELECT COMP_NAME, STATUS
FROM DBA_SERVER_REGISTRY;
i got all objects as valid, but i dont see "Oracle XML Database" anymore.
so now i suppose i cannot reinstall, but actually do a fresh install. and the following are the steps for a fresh install in the documentation
Installing a New Oracle XML DB Manually Without Database Configuration Assistant
After the database installation, you must run the following SQL scripts in rdbms/admin connecting to SYS to install Oracle XML DB after creating a new tablespace for Oracle XML DB repository. Here is the syntax for this:
catqm.sql <XDB_password> <XDB_TS_NAME> <TEMP_TS_NAME>
#Create the tables and views needed to run XML DB
For example:
catqm.sql change_on_install XDB TEMP
Reconnect to SYS again and run the following:
catxdbj.sql #Load xdb java library
Note:
Make sure that the database is started with Oracle9i release 2 (9.2.0) compatibility or higher, and Java Virtual Machine (JVM) is installed.
Postinstallation
After the manual installation, carry out these tasks:
1.     Add the following dispatcher entry to the init.ora file:
dispatchers="(PROTOCOL=TCP) (SERVICE=<sid>XDB)"
2.     Restart the database and listener to enable Oracle XML DB protocol access.
3.     To allow for unauthenticated access to your Oracle XML DB repository data through HTTP, you must also unlock the ANONYMOUS user account.
is this right. can u tell me what i should do please.
Thanks,
Philip.

Does Oracle XML parser support scripts?

I've tried using scripts in my XSL which I parse with Oracle XML parser v2. If the function does not exist, I get error. But if the function exists, I get nothing at all on the output! Not even simple function that only returns a string.
I also have the same problems with <xsl:eval>.
Thank you for reading this,
David.

We fully support the XSLT 1.0 Recommendation.
<xsl:eval> and <xsl:script>
are not features of the XSLT standard.

Fatal Error and NullPointerException in Oracle XML Transformer

Hi,
I'm building a dom tree in memory with oracle xml parser. Then I transform the dom document into a string to send xml to the client. But I get an fatal error on calling transform.
I don't know what could be the problem, because apache and weblogic parser works, an when I create a dom document with org.w3c.dom elements and statements then the xml document can't be invalid,
because the document implementation would throw an exception if wrong nodes or something like this should be inserted...
I'm using oracle xml parser 9.2.0.4 for java, bea weblogic 7.0 and win2k.
Thanks for help.

XML Parsing in Java Stored Proc--Oracle XML Support Installation?

I am working with a third party product that is having difficulty running a java stored proc that is parsing a supplied XML file. The proc basically looks like:
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
InputStream is = getXMLAsInputStream(xml);
try {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse( is );
... parse the document ....
catch (FactoryConfigurationError e) {
// unable to get a document builder factory
We are running on 9.2.0.6, HP-UX 64-bit. At first, when we would attempt to run the proc, a database hang would occur; now after attempting to install using loadjava jars for xerces2.6: ORA-29532: Java call terminated by uncaught Java exception:
javax.xml.parsers.FactoryConfigurationError: Provider
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found)
The vendor says that the errors we are getting when running are not due to any dependency on xerces or jre1.4, and that we need to "install Oracle XML support", but I'm not certain what this means (I cannot find any documentation on what to install). I believe that there are jars that need to be loaded into the database to support the XML parsing, as jre1.3 does not include built-in XML support, and Oracle 9.2.0.6 uses jre1.3.
So...does anyone have any thoughts as to how to resolve the missing references? Is there a way to "install Oracle XML support", or is it to install the necessary jars?
Thanks,
Candi

Candi,
The following resources should be of help:
Oracle9i Database Release 2 (9.2) Documentation Library
In particular, check out the following:
Java Developer's Guide
Java Stored Procedures Developer's Guide
XML API Reference - XDK and Oracle XML DB
XML Database Developer's Guide - Oracle XML DB
XML Developer's Kits Guide - XDK
If that doesn't help, then try the following:

Good Luck,
Avi.

XML support in Oracle 8i

Hi,
I have a requirement of storing XML documents in the Oracle
database. As Oracle claims support for XML in Oracle 8i, I would
be thankful if the following questions could be answered.
There will be around 15000 or more XML documents generated
annually, each of around 200 pages . Various views of the same
XML instance will be shown to different customers depending on
their preferences. All views will be generated dynamically and
the results will be sent as HTML pages to the client or XML
instances which will then be manipulated and shown as required
on the clients machine.
Please bear with me in case a few questions are naive
Questions :
1) Does Oracle 8i propose to have XML as a new datatype
2) Does a document descriptor mean the mapping of the XML
elements to certain columns in an Oracle table? Does it have
anything to do with the DTD? Will an XML instance be mapped to a
single table only or across multiple tables in a master-detail
relationship as the heirarchy in the instance gets too complex ?
3) How will the ConText cartridge be able to identify XML
documents? How will the queries be written to enable 'element-
level' searching?
4)What is iFS , especially in relation to XML storage?
Regards,
Kedar

A Document Descriptor is basicly a mapping between a DTD and the
tables and columns in the RDBMS. More that one table can be
mapped to.
: 3) How will the ConText cartridge be able to identify XML
: documents? How will the queries be written to enable 'element-

Context, now interMedia Text, does not 'identify' XML documents
per se, but can index colums with imbedded XML and search the
contents between specified tags.
: 4)What is iFS , especially in relation to XML storage?

Does Oracle XML Parser support double byte charset?

Hi,
Does Oracle XML Parser support double byte characters such as Korean or Chinese? If so, please tell me what version and how to construct xml/xsl files (...encoding="???")?
Thanks for any help,
Tuan

Hi Raymond,
Thank you for your help. It worked when I running in JDeveloper with your posted code. However, when I tried in my real application, it won't work.
The problem is for localization purposes, my application using some texts display in browsers are saved in Unicode file. Later, application runs and depends on languages setting in browsers, with JavaServlet retrieves those texts and saves in formated xml StringBuffer. Then, using existed XSL Stylesheet file and OracleXMLParser to generate an output HTML.
It has worked fine with English, France or others (single byte characters), but it can't
for double bytes character such as Korean or Chinese. I also tried different charset in xml file.
The following is one of returning errors:
-- oracle.xml.parser.v2.XSLException: XSL-1004: Error while parsing input XML document (<Line 1, Column 552>: XML-0221: (Fatal Error) Invalid char in text.)
I run this app in win2000/IIS with ServletExec3.0, JDK1.2.2 and OracleXMLParser v2.0.2.10
Thank you for any helps,
Tuan

Does Oracle XML Parser support Content Validation

Hi there,
Could someone out there give me a hint on whether the Oracle XML Parser has the capability of handling Content Validation? If yes, what's the mechanism behind it?
From my understanding of the Oracle XML Parser, even with the validating mode turned on, the parser only validates the XML data against the DTD (if any), which involves checking whether or not the attribute names and element tags are legal, whether nested elements belong to where they are, and so on. But I dont see any Content Validation. And my guess is that this feature, namely Content Validation, is simply not supported in the current version of the Oracle XML Parser. Am I right?
Any suggestion would be greatly appreciated. Thanks.
