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.

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.

Document on XML support in Oracle 8i

Hi.
I am looking for a brief document about Oracle 8i's support of XML. I am
aware of the whole book on XML under Online Documentation, but want a
more concise one. Could anyone 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:

Oracle 8i XML Support (Urgent !)

Hi
I would like to know the support offered by Oracle 8i for
storing XML documents in database and querying on them.
What component of 8i offers this support and in what way is it
different from support offered by PLSXML ?
I am looking to store XML documents in Oracle 8i database and
querying on them. Also I want to extract data from database and
dynamically generate HTML paged for on-line viewing.
This information is very crucial to me. Help of any kind is
welcome on the same.
Hoping for some quick replies,
Premal Mehta.

I am not sure to which features you refer? If you are asking
about the CONTAINS operator that works in 8i now. The document
registration to a schema will be delivered in the iFS beta.

Details on TAF support in Oracle AS 10g

Hi experts,
I'm currently writing a Master's Thesis on High Availability of Applications based on Suns JEE platform.
With Oracle being one of the big players in this market I'm going to investigate the features of the Oracle product stack and compare it with other solutions including opensource.
At the moment I'm looking for details on TAF-support in Oracle AS 10g. Lets assume one has installed the latest release of the Oracle 10g database in a RAC configuration on two or more physical nodes to store the applications data. Lets further assume one has set up the latest release of the Oracle AS 10g on different hosts building an AS farm with clustered OC4J-instances. Now one would like to connect a JEE application running within these OC4J-instances to the RAC database.
Therefore one can configure an OC4J datasource to use a service definition supporting network failover and transparent application failover (TAF) specified in the tnsnames.ora on the AS hosts or directly describe the service in the data-sources.xml. To my knowledge only datasources configured to use the OCI client can be used with TAF. Everything right so far?
Now the interesting part. The best what TAF can do is automatically reconnect to the next known database node if its current node is not reachable or fails, and continue processing an open cursor for select so that the application can continue to use its current connection.
If the application is running a database transaction it can only be rolled back and rerun after failover.
In a good old plain Java application one had to implement the OracleOCIFailover interface and register a callback with the db connection in order to receive failover events. Therefore you need to process the query in a different thread.
In a JEE server only the container should be responsible for creating threads, or? How does the Oracle AS support TAF? How can a user application get notice of a failover and react appropriately. Is the behaviour always the same no matter one decides to implement the data access via simple DAOs or entity beans (CMP/BMP)? I assume it is safe to use a connection pool and container will take care of the necessary cleanup jobs, right? Will the complete connection pool be reconstructed or only connections to the failed node?
Does the application server internally use these OCI callbacks and wrap them up into special Exceptions? Is there anything an application programmer has to do in order to make his data access code ready for TAF, especially in case of failover while the db is processing transactional code?
Any insights and/or code snippets would be greatly appreciated!
Ah, one last question. From a HA perspective is it generally a bad idea to put application logic into the database (use CDM RuleFrame and so on) as there is no support in preserving package states or do you think this makes no difference as one has always to repeat everything since the last commit point no matter in which tier the code resides?
During the next days Im going to set up the above environment for testing. A 10.0.2.1 RAC on RHE4 is already up and running fine. AS 10.1.3.0.0 on RHE4 is following today or tomorrow.
Many thanks for all answers!
Regards,
Eric

Hi,
well, I thought I could dig into the OC4J documentation before installing the server. After reading the OC4J Service Guide for 10.1.2 and 10.1.3 I'm a little bit confused.
First I read the 10.1.2 Service Guide and almost everything seemed to be clear. I found a lot of answers to the questions above. I'd like to sum them up. Please correct me if I got something wrong!
- TAF only works on top of OCI driver
- TAF can be used with connection pooling
- OC4J takes care of connection pool cleanup (OC4J and OCI Pool)
These two pools are mentioned. It's not clear to me how they work together. Do one of you know some source where I can get more information about this?
- after a failover all connections in the pool are checked by OC4J and only alive ones will survive
- in case of a failover TAF issues an exception
- the application has to catch this exception and acknowledge with a rollback, after that the transaction can be restarted (this seems to be the responsibility of the applications code, oc4j will not replay something automatically; If I got it right, CMP entity beans will be an exception to this rule - there OC4J will proceed transparently...)
- the application can use OCI callbacks to customize the failover behavior (well I would like to see some source code example here, as I can't imagine how this could look like)
After that I read the 10.1.3 service guide. The section about datasources in conjunction with HA is much shorter. Besides TAF new? mechanism is introduced, namely Fast Connection Failover (FCF). There is not much information about it but references to the JDBC Guide, because FCF is a feature of the implicit JDBC connection cache. Where cache seems to be just another word for pool.
By the way, the example on p. 4-36 looks wrong at first glance. Enabling FCF and setting:
<property name="fastConnectionFailoverEnabled" value="false"/> ???
Seems to be a typo in the docu, or?
I got the impression, that the text is written as if FCF being TAF's successor, without explicitly saying this. Is this right?
So I proceeded reading the JDBC Developer Guide to lean more about FCF. Here is what I learned:
- since 10g available
- FCF is driver independend (you can also use the thin driver)
- prerequisites are implicit connection cache (pool) enabled, ONS must be configured
- in case of a failover the transcation will be rolled back automatically (not by the application); whereas using TAF you have to use a rollback to acknowledge the error
- only one exception ORA-17008 to catch
- application has to obtain a new connection from the cache (pool), where as using TAF the old connection object can be used, and resend the transaction (same as with TAF)
So when to use what? The comparison on p. 27-8 was not very helpful to find an answer to this question.
On p. 28-1 one can read that TAF does not work with the OCI Connection Pool. That's seems to be contradictory to the statement in Service Guide of 10.1.2 that OC4J takes care of both pools (OC4J and OCI). Or has something changed in 10.1.3 in that regard? May be this is because of the changes in Cache or Pool Management?
What is the advantage of using TAF within OC4J in 10g, if there is any?
What about select statements with FCF? You can only read about transactions. I'd assume the application would get the same exception executing a query (ORA-17008) as executing a transaction, right? So TAF should have the advantage of transparently proceeding selects after a failover. Am I right?
I'd love to see more examples and comparisons of TAF and FCF.

Eric

XML DB in Oracle DB Express Edition?

Hi,
Can anyone tell if XML DB is available in Oracle 11g R2 Express edition?
Thanks in advance,
Divya

Please avoid duplicating (cross posting) threads.
Search the forum or see Licensing Information, to find that XML support is available, except for parts of it that depends on Java VM, which is not included.
http://docs.oracle.com/cd/E17781_01/license.112/e18068/toc.htm#BABJBGGA
Also, the EPG that Apex uses, is based on XML DB functionality, so it's obvious that (at least parts of) it is there.

You are out of luck. Oracle 9i is not a supported version.

Putting XML data in Oracle 8i tables.

Hi,
For a ongoing project, I have to put XML data in Oracle
tables. I have to parse the XMl and extract few key items and
the rest of the XML is to put into CLOB column. I am looking to
use Event-based parser.
I was trying to use Oracle XML parser for PL/SQL. This parser
does not have SAX support curently. Does anbody know by when
this parser support SAX? It has already been promised as one of
the feature.
Can somebody suggest using some other parser? Can I use some
parser which can be integrated within Oracle so that I wont have
to use ODBC etc. for accessing tables.
Has somebody used Oracle XMl parser for Java ? Does parser
integrate within Oracle. How can we go about the procs of
parsing and putting results in oracle tables.
Looking forward to quick response,
Premal.

There is no announced date for the addition of the SAX interface
to the PL/SQL Parser yet. Your current option is to use the XML

A valid SOAP will have content-type: text/xml

Load XML file to Oracle 10G XE

The load xml wizard in Oracle XE asks for a table in the HR schema to load into.
Well I create one using the 'Create Table' procedure with a script that runs and creates the table. Now I have a XML file that matches the table I created and try to load the file contents into the table. I get an error. Am I surprised? no, I am not. Nothing works the first time.
Is there a preferred format for the xml file that supports loading into a table?
There appears to be no help file, but then I may be mistaken.
Could someone show me where to find this help file?

The bug you are referencing occurs when an Enumerated Value also has min and max lengths specified..

     </xsd:annotation>

           </xsd:simpleType>
         </xsd:element>
      </xsd:sequence>
    </xsd:complexType>
</xsd:schema> Do you have something like this in your XML Schema. If this is the case try removing the minLength, maxLength as they are redundant, which is probably why we didn't catch this one in internal testing, it sort of falls into the "if it hurts please don't do it" category :). Also the fix for this bug appears to have been backported on top of 9.2.0.6.0 so upgrading to 9.2.0.7.0 or 9.2.0.8.0 or the later releases of 10.1 or 10.2 should fix the problem.

No improvement. please help me out of this.
how can i get arabic support in oracle AS by using jstl?
Thanks,

Only Apple Account Security could help at this point. You can try calling Apple Support in Canada - you'll have to find one of the several ways, such as Skype, to call an 800 number from outside of the relevant country - and ask for Account Security and see if they can help. Or you can find a friend who speaks Chinese and ask them to help you talk to Apple Support in China. There are really no other options that I know of.
Note, by the way, that these are user-to-user support forums. You aren't speaking with Apple when you post here.
