Dbms_xmlschema.deleteschema hangs
Hi,
I am trying to delete an already registered schema using:
dbms_xmlschema.deleteschema('http://myurl', dbms_xmlschema.DELETE_CASCADE_FORCE);
This API does not complete and hangs forever. I am running this on Oracle 11g R2 database. Please help.
Thanks,
Ramesh
It's more likely that there is a session somewhere that has retrieved data from an object associated with the XML Schema and is still holding a 'PIN' on it...

DBMS_XMLSCHEMA commands concurrent executing
Java class methods execute statements 'DBMS_XMLSCHEMA.registerSchema' and 'DBMS_XMLSCHEMA.deleteSchema' on Oracle 9i through JDBC using Jboss 4.0.0.
Several users may request these service simulaneously and the following happens: one or both actions fail; after that records not associated with any registered schema can be found in 'user_xml_schemas' table or node for a schema url exists in the tree (Oracle treat this as the schema is registered) but no correspondent records can be found in 'user_xml_tables' and sometimes in 'user_xml_schemas'; then we cannot register any schema until we stop server and start it again. The methods, which are responsible for DBMS_XMLSCHEMA statements executing, first look up data source by JNDI-name, then call getConnection() of DataSource instance, then try to execute DBMS_XMLSCHEMA statement, e.g."BEGIN DBMS_XMLSCHEMA.registerSchema('some_url', 'some_valid_xsd_as_String'); END;", then close connection.
How can I avoid the situation described above? Or can I somehow prohibit executing any DBMS_XMLSCHEMA commands until a job is done (by Oracle means)?Sofia,
One possibility:
If you write an Oracle procedure/package and store it in the database, you could call this procedure/package instead of the dbms_xmlschema package. Then test for other sessions active from the user account with a select from the v$session view where username = the username your using. If there is an active session you could terminate the incoming session. If no active session you could then call the dbms_xmlschema package from your package passing it the correct information and execute immediate the registerschema. -
How do you "unregister a schema". The following is being used to register and validate but it will not "reregister". getting the following error:

DBMS_XMLSCHEMA.CopyEvolve produces ORA-30945: Could not create mapping tabl
Hi,
I am trying to update a XML Schema concerning the documents relaties.xsd (the old one) and relaties_v2.xsd (the new one containing only a minor change).
The document relaties.xsd looks like this:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xdb="http://xmlns.oracle.com/xdb"
elementFormDefault="unqualified"
attributeFormDefault="unqualified"

<xsd:element name="Geslacht">

<xsd:enumeration value="M"/>
<xsd:enumeration value="V"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="Sofinummer">

<xsd:element name="Woonplaats" type="xsd:string"/>
<!--xsd:element name="Postcode" type="xsd:string"/-->
<xsd:element name="Postcode">

<xsd:restriction base="xsd:string">

</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="Zrn">
<xsd:simpleType>
<xsd:restriction base="xsd:integer">
<xsd:minInclusive value="1000000"/>
<xsd:maxInclusive value="99999999999999"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
Here are the steps I took.
DECLARE
res BOOLEAN;
BEGIN
res := DBMS_XDB.createResource('/xsd/relaties.xsd',
bfilename('XSDDIR', 'relaties.xsd')
END;
DECLARE
res BOOLEAN;
BEGIN
res := DBMS_XDB.createResource('/xsd/relaties_v2.xsd',
bfilename('XSDDIR', 'relaties_v2.xsd')
END;
BEGIN
DBMS_XMLSCHEMA.registerSchema(
'http://localhost:8080/xsd/relaties.xsd',
XDBURIType('/xsd/relaties.xsd').getClob(),
TRUE,
FALSE,
FALSE,
TRUE);
END;
CREATE
TABLE relatie_documenten OF XMLTYPE
XMLSCHEMA "http://localhost:8080/xsd/relaties.xsd"
ELEMENT "Relatie"
CREATE OR REPLACE
TRIGGER upo_rdt_ai
AFTER INSERT ON relatie_documenten
FOR EACH ROW
DECLARE
doc XMLType;
BEGIN
doc := :new.SYS_NC_ROWINFO$;
XMLType.schemaValidate(doc);
END;
Then I inserted some xml documents into the table relatie_documenten. The XSD worked fine.
Then I executed the following statement:
BEGIN
DBMS_XMLSCHEMA.copyEvolve
( schemaURLs => xdb$string_list_t('http://localhost:8080/xsd/relaties.xsd')
, newSchemas => XMLSequenceType(XDBURIType('/xsd/relaties_v2.xsd').getXML())
, preserveOldDocs => TRUE
, mapTabName => 'RELATIE_DOCUMENTEN_TEMP'
, generateTables => FALSE
END;
This resulted in:
ERROR at line 1:
ORA-30945: Could not create mapping table 'RELATIE_DOCUMENTEN_TEMP'
ORA-00600: internal error code, arguments: [kqludp2], [0x66AB407C], [0], [],

ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 210
ORA-06512: at line 2
I checked system priviliges as documented in XML DB Developers Guide, Chapter 8 XML Schema Evolution. No other users were connected. The mapping table RELATIE_DOCUMENTEN_TEMP nor any other object named RELATIE_DOCUMENTEN_TEMP did not exist.
Anyone an idea why I cannot create my mapping table ?

About dbms_xmlschema.delete_cascade_force
with oracle 10g.
1. exec dbms_xmlschema.registerschema('http://someurl', bfilename('SOMEFOLDER','some.xsd'));
2. create table TTT (key_col varchar2(10) primary key, xml_col xmltype)
xmltype column xml_col xmlschema "http://someurl" element "Fields"
3. insert into TTT values('001', xmltype(bfilename('SOMEFOLDER', 'data01.xml'), nls_charset_id('AL32UTF8')));
4. exec dbms_xmlschema.deleteschema('http://someurl', dbms_xmlschema.delete_cascade_force);
after step 4,
desc TTT will got ORA-24372
select count(*) from TTT will got ORA-04063
Could anyone tell me how to resolve this problem with no loss of TTT's data?No..
This one falls into the cateogory of "If it hurts please don't do it"
DELETE_CASCADE_FORCE should only be used when you are sure that you do not care for the content of any tables or columns that are based on the XML schema.. Please don't tell me you've done this in a a production system and now you need the data, because "There is no way to recover this data" except from a backup of the database before the schema was deleted...
Basically once the XML Schema has gone we have no way to correcly interpret the contents of the tables that contain the content of the documents.

SQL>The mistakes included the XPath used to insert the new element into the XML Schema
You had
'/xsd:schema/xsd:complexType[@name="companyinfo"]/xsd:sequence',
where as the correct XPath is
'/xsd:schema/xsd:complexType[@name="companyinfoType"]/xsd:sequence',
and then you had
if (dbms_xdb.existsResource('/public/personDetails.xsd')) then
dbms_xdb.deleteResource('/public/personDetails.xsd');
end if;
res := dbms_xdb.createResource('/public/newpersonDetails.xsd',xmlschema);
end;
which means that once the document newpersonDetails.xsd had been created once a subsequent execution of the testcase would fail as the document would already exist.
I'm also a little confused... Your testcase implies that you were able to insert the second document, but the number of rows in the table is still shown as 1 after the insert apparently succeeded. Since you did not correctly update the XML Schema before the calling copyEvolve I do not understand how your output shows that the second insert succeeded. -
Loading datafrom a PL/SQL table into the Database table
I have created two procedures to try and achieve the problem at hand.
It retrieves and displays the record from a DBMS_OUTPUT.PUT_LINE prospective as indicated in (1&2), but I am having difficulty loading these values into a PL/SQL table from the package labeled as (3). I read your book and all but I do not see a solution to my problem
All code compiles. (1&2) work together, (3) works by itself but will not populate the table, and I get no errors.
1.The first being the one that retrieves the XML file and parses it.
CREATE OR REPLACE procedure xml_main is

ORA-31000: Resource 'example_name.xsd' is not an XDB schema document
Morning,
I'm running 11gr2 on OEL 5. I recently joined a project where a lot of work has already been done by a previous dba and xmldb is fairly new to me. I'm trying to register a new xml schema but keep getting the above error. The error is referencing a resource that I'm not even declaring in my statement. See statement below.
BEGIN
DBMS_XMLSCHEMA.registerSchema(
SCHEMAURL => 'http://localhost/xsd/test/collection_test.xsd',
SCHEMADOC => bfilename('XSD_TEST','collection_test.xsd'),
CSID => nls_charset_id('AL32UTF8'));
END;
I've used the FORCE=True option which has worked but then the error shows up again when trying to create a table. I queried the schema url and found that nothing was mapped to it so I deleted it as so:
DBMS_XMLSCHEMA.DELETESCHEMA('http://localhost/xsd/test/collection_test.xsd', DBMS_XMLSCHEMA.DELETE_CASCADE_FORCE);
This worked just fine. Problem now is, I'm still getting the same error when registering schema or creating a table. I thought maybe I could purge t he schema from the database now but I can't query the schema ID to do so. I feel I am stuck now. I've tried to look up solutions online for a day now to no avail. All help is GREATLY appreciated (and rewarded). Thanks!!I don't expect to be able to give you the answer you seek, but I'll ask a couple of questions to help others along.
1) What is your error message? That is useful
2) What does collection_test.xsd look like? Can you post it (or a portion of it, including any includes/imports and all namespaces)?
Reproducible test cases are always nice as they show others what is going on and give a starting point for reproducing/fixing the error. -
How to create XML from relational tables based on an XML Schema ?
There is no automated way in Oracle XML DB to define an automatic mapping between a set of columns in some existing relational tables and the elements and attributres defined by an XML Schema.
However it is easy solve this problem by using the SQL/XML operators (XMLAGG, XMLELEMENT, XMLFOREST, XMLATTRIBUTES, etc) to generate XML documents that are compliant with an XML Schema directly from a SQL statement.
If the XML Schema is registered with Oracle XML DB and the appropraite Schema Location information is added into the generated document using XMLAttributes then it becomes very easy to ensure that the generated documents are valid.
The following example show an easy way to do this by creating an XML View that contains the documents to be validated.

SQL>There is no automated way in Oracle XML DB to define an automatic mapping between a set of columns in some existing relational tables and the elements and attributres defined by an XML Schema.
However it is easy solve this problem by using the SQL/XML operators (XMLAGG, XMLELEMENT, XMLFOREST, XMLATTRIBUTES, etc) to generate XML documents that are compliant with an XML Schema directly from a SQL statement.
If the XML Schema is registered with Oracle XML DB and the appropraite Schema Location information is added into the generated document using XMLAttributes then it becomes very easy to ensure that the generated documents are valid.
The following example show an easy way to do this by creating an XML View that contains the documents to be validated.

Oracle 10g R2 - Metadata Issue With Version Controlled Resources
We are trying to utilize the Oracle 10g R2 feature that allows user-defined metadata to be attached to XML DB resources. However, we are encountering errors when we try to append/attach metadata to a version-controlled resource (VCR). The following steps were followed:
1. Register a new schema to be used for metadata (XMLSCHEMA.registerSchema).
2. Add a new resource to to the XML DB and make it version controlled (DBMS_XDB.createResource and DBMS_XDB_VERSION.makeVersioned).
3. Checkout the newly created version-controlled resource (DBMS_XDB_VERSION.checkout)
4. Add metadata to the version-controlled resource (DBMS_XDB.appendResourceMetadata)
However, after step 4, the errors shown below are encountered:
========================================================
begin
ERROR at line 1:
ORA-00600: internal error code, arguments: [qmxStrCopy: INLOB 2], [], [], [],
ORA-06512: at "XDB.DBMS_XDB", line 890
ORA-06512: at line 2
========================================================
The steps followed for adding metadata to a resource were taken from Chapter 26 of the "Oracle XML DB Developer's Guide 10G Release 2" (http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb_repos_meta.htm#sthref2302).
Is is possible to append and maintain metadata to an XML DB version controlled resource (VCR)? If so, what are the correct steps to do this? Note that if this is tried with a resource that is not version controlled, then no errors are encountered.
Thanks,
SteveIt appears that this issue has been solved in the next release of the database

Disconnected from Oracle Database 11g Enterprise Edition Release 11.1.0.0.0 - Alpha
With the Partitioning and Data Mining options
I've filed bug 5313655 for the 10.2.x behavoir. If this is important to you you might want to consider signing up for the forthcoming beta program for the next release of the database -
ORA-07445 in the alert log when inserting into table with XMLType column
I'm trying to insert an xml-document into a table with a schema-based XMLType column. When I try to insert a row (using plsql-developer) - oracle is busy for a few seconds and then the connection to oracle is lost.
Below you''ll find the following to recreate the problem:
a) contents from the alert log
b) create script for the table
c) the before-insert trigger
d) the xml-schema
e) code for registering the schema
f) the test program
g) platform information

Kind Regards,
EyðunYou should report this in a service request on http://metalink.oracle.com.
It is a shame that you put all the effort here to describe your problem, but on the other hand you can now also copy & paste the question to Oracle Support.
Because you are using 10.2.0.3; I am guessing that you have a valid service contract... -
How to improve performance of a query that is based on an xmltype table
Dear Friends,
I have a query that is pulling records from an xmltype table with 9000 rows and it is running very slow.
I am using XMLTABLE command to retreive the rows. It is taking upto 30 minutes to finish.
Would you be able to suggest how I can make it faster. Thanks.
Below is the query.....

Permission issues accross schemas to load XMLTYPE column - structured storage
Hi,
We have a table in BIUSER schema this table is object-realtionally stored with XMLs. When we are trying to load receords from ETLUSER schema we are getting the error as
Record 1: Rejected - Error on table "BIUSER"."PWAYWORKFILE_TABLE".
ORA-00604: error occurred at recursive SQL level 1
ORA-01031: insufficient privileges
Heres the oracle installation details
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
"CORE 11.2.0.3.0 Production"
All the records are moving to the bad file, whereas the same load happens normally in its own schema i.e. BIUSER
Suspecting this as permission issues we have already given the permission to the table sysnonym as given below in the registration script.
We googled and found few things about ACLs that we are not sure of , its that is the issue please let us know if this table can be created and loaded from different schema
Heres the table creation and registration script

Regards,
ArghyadipHi MarcoGralike,
I have finally acquired a sample schema and xmls to reproduce the errors that i am getting even after acquiring XDBADMIN privilege and registering my schema as GLOBAL.
Here's the problem i am facing, whenever i intend to store the PublisherList (publisher.xsd) out of line while registration i am running into insufficient privilege issues even if i have the schema registered using (LOCAL => FALSE), whereas it runs smooth in BIUSER and if i dont set it out of line it works in ETLUSER as well.
Here are the 2 XSD files
books.xsd --- this is the root element
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" version="1.0" xdb:storeVarrayAsTable="true">
<xs:include schemaLocation="publisher.xsd"/>
<xs:element name="books" type="bookType"/>
<xs:complexType name="bookType" abstract="true">
<xs:sequence>
<xs:element name="author" type="xs:string" minOccurs="0"/>
<xs:element name="title" type="xs:string" minOccurs="0"/>
<xs:element name="genre" type="xs:string" minOccurs="0"/>
<xs:element ref="PublisherList" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
publisher.xsd -- this is a child elelment which in my actual scenario is so big that i must keep it out of line during registration
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" version="1.0" xdb:storeVarrayAsTable="true">
<xs:element name="PublisherList" type="PublisherListType"/>
<xs:complexType name="PublisherListType">
<xs:sequence>
<xs:element name="Name" type="xs:string" minOccurs="0"/>
<xs:element name="Office" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
Here's the sample XML
<?xml version="1.0"?>
<books xmlns:xs="http://www.w3.org/2001/XMLSchema">
<author>Writer</author>
<title>The First Book</title>
<genre>Fiction</genre>
<PublisherList>

Hopefully i have given you all the set up required to pin point the evil error.
Please let me know if i have missed something. -
Actually I have a problem relating to Oracle 10g XML DB. Ill explain the scenario.
1. First an xml file needs to be loaded into the database( after registering the schema)
2. Later maybe after inserting suppose 10 xml files into the table, I need to add an element in the xml.
3. And the new xml's which are later loaded will have that additional field coming in. so how should I go about from here.
What Ive thought is:
1. Generate a new XSD schema (dont know how to generate this automatically), implementing the additional field change.(can u help me in this)
2. Create a new XSL depending on the new XSD schema (dont know how to generate this automatically). (can u help me in this)
3. apply the new xsl to the original xml to get the new xml.
4. in the meantime, keep the old xml in a temporary tables, and later, update those xml corresponding to the new schema (can u help me in this)
I dont know if this a correct procedure, if in case, there is a different and an easy method to do it, please let me know.
regards,

where msg_id = 8
and I get the error:
ORA-30937: No schema definition for 'MESSAGE_NUMBER' (namespace 'http://www.forensic.gov.uk/eMessages/Pnclink/NDNA') in parent 'MESSAGE_HEADER'
ORA-06512: at "SYS.XMLTYPE", line 0
ORA-06512: at line 27
But if I remove the MESSAGE_NUMBER I get
ORA-31154: invalid XML document
ORA-19202: Error occurred in XML processing
LSX-00213: only 0 occurrences of particle "MESSAGE_NUMBER", minimum is 1
ORA-06512: at "SYS.XMLTYPE", line 0
ORA-06512: at line 37
So it knows there is supposed to be a particle called message_number if it's not there, but not what to do with it if it is.
One other thing, which I think is significant: If I amend my test.xsd schema so I define MESSAGE_HEADER there, so the only thing being referenced from testinclude.xsd is the SIMPLE type "MessageTypeType", I don't have a problem. It seems to be only when I include COMPLEX types.
Any suggestions?Dave
I can't register the XML Schemas with XML DB, since we do think versionfiltered is a valid attribute for a schema element...
