Is Oracle XML DB a native xml database?

Hi!
XML DB provides native data type XMLTYPE, and it can provide traditional storage for xml. So is it a enabled xml database or a native one??
Cheers

It is an XML enabled relational database (XMLType OR storage) but has also native XML database capabilities in the form of binary XML (XMLType Binary XML storage)

VB6 & XML Datasource using Native XML Driver

We used to use reports that used ADO XML dataset, and in VB 6 we easily told the report which XML file to use by:
Dim objCRReport As CRAXDRT.Report
Set objCRReport = objCRApplication.OpenReport(App.path & "\crystal\" + rptName)
objCRReport.DiscardSavedData
objCRReport.Database.Tables.Item(1).Location = xmlFile
where xmlFile was the fully qualified path to the xml data to pass to the report.
Now we are trying to do this with a new report which uses a XML Native driver as its connection method. In VB6, how can we pass different xml files to use?
We looked at objCRReport.Database.SetDataSource, but it expects some parameters that I don't understand ( data , { data type } , { table number } )
Is there an example anywhere of how to switch your datasource in code while using the XML Native Driver?

See [this|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes.do] note.
I would also recommend that you read the following regarding distribution of the runtime. This is important as the xml driver (crdb_xml.dll) uses Java:
Apart from the regular deployment procedure for COM/RDC/NET applications, you have to follow the additional below-given steps in the client machines.
Install the Java (JVM) 2 Runtime Environment (this is essentially the Java Framework needed to launch the crdb_xml native driver 1.4.2 from the java sun web site at:
http://java.sun.com/j2se/1.4.2/download.html.
Create a java folder inside the " C:Program FilesBusiness ObjectsCommon3.0";.
Copy over the Crconfig.xml(C:Program FilesCommon FilesBusiness Objects3.0java) file from the development machine to the deployed machine in at the following path "C:Program FilesCommon FilesBusiness Objects3.0java" path. Open the crconfig.xml ; this file in Notepad and search for the line <JavaDir>. If JRE is installed to C:Program FilesJavaj2re1.4.2_12 in then the value should be look like this <JavaDir> C:Program FilesJavaj2re1.4.2_12 in</JavaDir>.
Create a folder called lib in the "C:Program FilesCommon FilesBusiness Objects3.0java".
Copy over the entire contents of the lib folder (especially the external folder) from the development machine to the newly created lib machine on the deployed machine. The point of this is to ensure that the crconfig.xml file contains all the files here which exist at the correct path which they now should because we copied over the lib and external directories.
Copy crdb_xml.dll, crdb_xml_res_en, and all the files with "crdb_xml_res_xx from your development machine to the deployment machine (C:Program FilesCommon FilesBusiness Objects3.0 in).
Restart your machine and try accessing your web application. The reports will show up the data without any issue.
The above is written for CR XI release 1. You may have to adjust the path given above as you do not specify the version of Crystal reports you are using.

How to use native XML driver in CR XI 2 (to avoid "Database Logon Failed")?

Hello,
I have a simple scenario:
The Java Part:
-Our Java application creates a pair of files: one XML and one XSD.
-Both files are uploaded to an ASP.NET page along with a report (RPT file - based on the same XSD and some generated XML using the native XML driver) for rendering a PDF.
The ASP.NET(VB) Part:
-Reads and stores 3 files (XML, XSD and RPT) to temporary files.
-Loads the report
-Updates connection attributes ("Local Schema File" and "Local XML File") to point to those temporary files.
-Exports the report to a PDF which is returned to the Java part.
What are the correct steps to accomplish this? I keep on getting "Database logon failed." exceptions.
My code looks like this:
Dim doc As ReportDocument = New ReportDocument
doc.Load(rptPath)
Dim attr As DbConnectionAttributes
attr = New DbConnectionAttributes()
attr.Collection.Set("Local Schema File", xsdPath)
attr.Collection.Set("Local XML File", xmlPath)
Dim conn As IConnectionInfo
conn = doc.DataSourceConnections.Item(0)
conn.Attributes.Collection.LookupNameValuePair("QE_LogonProperties").Value = attr
conn.Attributes.Collection.LookupNameValuePair("QE_ServerDescription").Value = xmlPath & " " & xsdPath
conn.Attributes.Collection.LookupNameValuePair("QE_SQLDB").Value = False
doc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, False, "")
Thank you for any help,
David

Hi,
When you get a database logon prompt like this it normally means the dataset you're creating at runtime does not match the schema that the report was designed with.
The simplest thing to do is write out the dataset to XML with Schema after you fill the dataset. Once you've written out the dataset you can go back to the report in Crystal Reports itself and try to point the report to the XML file directly. If you get any errors this confirms that the dataset does not match what the report is expecting.
Try it, address any differences, and you should be all set.
Sincerely,
Amit

Native XML Driver Deployment

For a while we had trouble using the native xml driver, but it has been worked out here:
VB6 & XML Datasource using Native XML Driver
In that thread there was mention of deploying the driver, and some extra work that needed to happen. I found those instructions repeated again here for another user:
https://boc.sdn.sap.com/node/1428
We have followed the instructions of coping the required files and java runtime to a new test client, but our reports do not launch.. we get this error after a good 30 seconds of hang-time,
Invalid Argument Provided
I've doubled checked the instructions and all files are copied, and edited the crconfig.xml to point to the new j2re bin folder. There doesn't appear to be many discussions with this error, what does it mean? Thanks.
Note that we are using the RDC, Native XML Driver, Crystal Reports XI R2 SP4.

Ok I went over the process again, and am a little confused -

Native XML Database

Does anyone know if DSP will ever ship with a native XML database? It makes sense to me, given the XQuery strategy, that a native XML database would make sense for storing data that is not in an external system.

Can you elaborate a little on what you would like to do?
Currently you can use XQuery and SDO to store and query data in a database. It shouldn't matter if it is a true XML database or Oracle, or something else.

Not able to create XML from an existing relational database

Hi,
I am trying to create and xml from an existing relational database. I am not able to get any XML data, I receive "XMLTYPE()" as the result.
Here's the query -
SQL> select o.order_id, XMLELEMENT("order", XMLATTRIBUTES(o.order_id as ID)) AS "result" from order_
info o where order_id=2793;
ORDER_ID
result()
+2793+
XMLTYPE()
I was expecting to get +<order id=2793 />+ instead of XMLTYPE().
I am using -
SQLPlus: Release 9.0.1.0.1*
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
I have also run some checks to confirm XML DB installation -
SQL> select 1 from all_users where username = 'XDB';
+1+
+1+
SQL> desc RESOURCE_VIEW;
Name                                      Null?    Type
RES                                                SYS.XMLTYPE
ANY_PATH                                           VARCHAR2(4000)
RESID                                              RAW(16)
I think, I have something wrong with installation or configuration.
Any idea about what have I done wrong here?

Works fine now. Got the result "<order ID="2793"></order>".
Thanks. :-)

XML SCHEMA registration for XML TYPE (storing XML files in Oracle 10g)

I have created the XML Schema for the XML file stored in Oracle 10g and also added this Schema into the database. I have related that schema with the column in the table which contains the XML file. When i execute the query to fetch the data from the stored file i am getting a blank resultset. Is registering the XML Schema is necessary, if yes then please let me know the process of doing it. I have tried following steps to register Schema, but it is not working
Step1:
DECLARE
v_return BOOLEAN;
BEGIN
v_return := dbms_xdb.createFolder('/home/');
v_return := dbms_xdb.createFolder('/home/DEV/');
v_return := dbms_xdb.createFolder('/home/DEV/xsd/');
v_return := dbms_xdb.createFolder('/home/DEV/messages/');
v_return := dbms_xdb.createFolder('/home/DEV/employees/');
COMMIT;
END;
STEP 2:
Connecting To XML DB
Step3:
Register XML schema
I am failing to execute step number 2 and hence not able to register the schema also.

DeleteXml() causing xml data format error in database

Hi, guys,
I'm using the oracle xml db 11g in my website application. Last week I found that using the deletexml() to delete a node in the xml may cause a terrible problem that the rest data in the database had wrong xml format. I wonder is it a bug when using binary xml storage.
My xml data is describe below,
<root>
     <nodes>
          <node id="1">
               <name>John</name>
               <age>16</age>
               <hobby>football</hobby>
          </node>
          <node id="2">
               <name>Alex</name>
               <age>22</age>
               <hobby>table tenisl</hobby>
         </node>
     <nodes>
</root>
I using deletexml() to delete just a node once time,
"update projects set object_value=deletexml(object_value, '/root/nodes/node[@id="1"]')"
Usually it successes and the rest data is as excepted, but sometime, I find that after deleting a node, any query in the database except "select * from projects" gets null. And the rest data has wrong format like below,
<root>
     <nodes>
          <node id="1">
               <name>John</name>
               <age>/hobby>
          </node>
          <node id="2">
               <name>Alex</name>
               <age>22</age>
               <hobby>table tenisl</hobby>
         </node>
     <nodes>
</root>
Just one format error causes the whole xml data valueless, but it seems that in most time the deletexml() works well, does anyone knows what happens?
Thanks a lot.

XMLPatch?
Do you use it yourself on a regular basis?
Personally, I find it fun to use but the performance doesn't match my expectations (no piecewise update/streaming eval AFAIK).

Special Character Restrictions for Native XML Driver

Hi,
I have found the following special character restrictions in the documentation:
"Because they are handled specially by the Native XML driver, do not use the following special characters to define element types and attributes in your XML schema:u201C.u201D, u201C/u201D, u201C\u201D, u201C:u201D u201C@u201D."
After checking the createad XML-Files in our projects that we will use for CR4E there is often a u201C.u201D in the definition. Because this is delivered from third-party, we wish that the u201C.u201D will be enabled.
In the moment we create the XSD-Files from the XML-File with XML2XSD.
It is possible in the future?
Best Regards
Arnold Meier

The changes aren't in XI Release 2, but in 2008.
Do you still have Nha's XML data? I edited Document_Policy, Policy_AllCoverages, Policy_Beneficiary to Document.Policy, Policy.AllCoverages, Policy.Beneficiary, then use the following code in CR4E 2.0:
reportClientDocument reportClientDocument;
ConnectionInfo connectionInfo;
PropertyBag propertyBag;
* Connect to the Java Print Engine and create a new document.
reportClientDocument = new ReportClientDocument();
reportClientDocument.setReportAppServer(ReportClientDocument.inprocConnectionString);
reportClientDocument.newDocument();
* Define connection to the XML and XSD files.
propertyBag = new PropertyBag();
propertyBag.put("Local XML File", "C:\\Documents and Settings\\tueda\\Desktop\\nha.xml");
propertyBag.put("Local Schema File", "C:\\Documents and Settings\\tueda\\Desktop\\nha.xsd");
propertyBag.put("Convert Multivalue to Table", Boolean.FALSE);
propertyBag.put("Database DLL", "crdb_xml.dll");
connectionInfo = new ConnectionInfo();
connectionInfo.setAttributes(propertyBag);
* Specify the dataset in the XML as a Table, and add to the report.
Table table = new Table();
table.setConnectionInfo(connectionInfo);
table.setName("Document.Policy/Policy.Beneficiary");
table.setAlias("Document_Policy/Policy_Beneficiary");
reportClientDocument.getDatabaseController().addTable(table, null);
* Save report to file C:\local_xml.rpt
reportClientDocument.saveAs("nha_local_xml.rpt", "C:\\", ReportSaveAsOptions._overwriteExisting);
reportClientDocument.close();

Can I have Oracle Application Server to work XML DB

I am new to XML DB. I read some of the document about XML DB. It looks like that I have to configure a DAD in Database. It looks like the database is served as an Application Server. I am wandering if I can use Oracle AS to work with XML DB to achieve the the same results.
Thanks a lot!

Question on Native XML Builder

Hi everyone,
I am working in SOA11g, using File Adapter component and then using Native XML Builder to convert a cobol copy book file to native xml file.
I have chosen the option to create New> Create cobol copy book to native xml
- I gave the file name with .txt extension.
- Entered TargetNamespace
- Root-Element: Root-Element
- Character Set: UTF-8
- Big endian
Records Delimiter: End of Line ($eol)
Is something wrong with these entries, I get an error 'Unable to generate native format': Is there a way to get the detailed error description.
Please advice.
Thanks.

Hi,
You need to target the cobol copy book schema file, not the data file (just to be sure because it is not clear from the ".txt" extension)
Also, if the schema file is not compliant to Jdev then it will show this kind of error.
Check that all the declarations made in the schema file are supported by Jdev native builder (particularly the iteration one).

Xml data into non-xml database.. solution anyone?

Hi,
My current project requires me to store the client's data on our servers. We're using Oracle9i. Daily, I will download the client's data for that day and load it into our database. My problem is that the data file is not a flat file so I can't use sql*loader to load the data. Instead, the data file is an xml file. What is the best way to load xml data into a non-xml database? Are there any tools similar to sql*Loader that will load xml data into non-xml database? Is it the best solution for the client to give me an XML dump of their data to load into our database, or should I request a flat file? My last resort would be to write some sort of a script to parse the xml data into a flat file, and then run it through sql*loader. Is this the best solution? One thing to note is that these files could be very large.
Thanks in advance.
-PV

I assume that just putting the XML file into an
extremely large VARCHAR field is not what you want.
Instead, you want to extract data elements from the
XML and write them to columns in a table in your
database. Right?Yes. Your assumption is correct.
It sounds like you already have a script that loads a
flat file into your database. In that case I would
write an XSL transformation that converts the client's
XML into a correctly-formatted flat file.Thank you. I'll look into that. Other suggestions are welcome.

There is no automatic way to generate XML documents from an arbitary set of relational tables using the information contained in an XML Schema. Typically the easiest way to generate XML from relational data is to use the SQL/XML operators (XMLElement, XMLAGG, XMLAttribtues, XMLForest). There are many examples of using these operators in the forums You can validate the generated XML against the XML Schema by registering the XML Schema with XML DB and then using the XMLType.SchemaValidate() method
