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.

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...
Re: Deleting XML Schema

ORA-03113 when using references in xmltype

I get an 'ORA-03113: end-of-file on communication channel' if I try to use references in an xml schema on multiple levels. You can find an example below.
Setup:
exec dbms_session.reset_package;
declare
l_schema varchar2(32767) :='<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="qualified"
elementFormDefault="qualified"
version="1.0"
xmlns:xdb="http://xmlns.oracle.com/xdb"
xdb:storeVarrayAsTable="false"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="T_NODE" xdb:SQLType="T_NODE">
<xs:sequence>
<xs:element name="NODE" type="T_NODE"/>
<xs:element name="LEVEL" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:element name="NODE" type="T_NODE" xdb:defaultTable="T_NODE_REF"/>
</xs:schema>';
l_xml xmltype;
l_url varchar2(1000) := 'NodeTest.xsd';
begin
begin
execute immediate 'drop table T_NODE_REF';
exception
when others then null;
end;
begin
execute immediate 'drop table T_NODE_XML';
exception
when others then null;
end;
begin
dbms_xmlschema.deleteschema(
schemaurl => l_url
,delete_option => dbms_xmlschema.delete_cascade_force
exception
when others then null;
end;
l_xml := xmltype.createxml(l_schema);
dbms_xmlschema.registerschema (schemaurl => l_url
,schemadoc => l_xml
,gentables => true
execute immediate 'CREATE TABLE T_NODE_XML OF XMLTYPE XMLTYPE STORE AS OBJECT RELATIONAL XMLSCHEMA "' || l_url || '" ELEMENT "NODE"';
end;
The script:
declare
l_reference ref xmltype;
function rec(
i_level pls_integer
) return ref xmltype
is
l_url varchar2(1000) := 'NodeTest.xsd';
l_ref ref xmltype := null;
l_new_ref ref xmltype := null;
l_node t_node;
l_level pls_integer;
l_node_xml xmltype;
begin
if i_level > 0 then
l_level := i_level - 1;
l_ref := rec(l_level);
else
l_ref := null;
end if;
l_node := new t_node(null, l_ref, i_level);
l_node_xml := xmltype.createxml(xmlData => l_node, schema => l_url, element => 'NODE', validated => 1);
dbms_output.put_line(dbms_lob.substr(l_node_xml.getClobVal, amount => 200, offset => 1));
insert into T_NODE_XML t values(l_node_xml) returning ref(t) into l_new_ref;
commit;
return l_new_ref;
end;
begin
l_reference := rec(1);
end;
Any idea how to overcome this issue?
Thanks in advance

Your previous reply never said anything about commenting out dbms_output so how was I supposed to see the variations you were trying?<br><br>
You need to continue this discussion with Oracle as to why you getting the specific ORA-0600 that you are. This assumes you have a valid support contract. You are getting an internal Oracle error. I'm not Oracle nor do I know the inner workings of their system. If not, Google and maybe the XML DB forum might be able to help you with this issue. They will want to know your version (4 digits) and may question your hammer use of .delete_cascade_force when deleting the schema. This should only be a last resort to use that level I know. It's probably not related to your issue but may come up.

Structured storage XMLType but disappointing performance

Hi,
This relates to Oracle 11g, but maybe the same question can be asked for 10g.
I'm having a lot of big XML files which are structured following this xsd:

VARRAY "XMLDATA"."ea"."eb"
    STORE AS TABLE simple_nested1

/And I load some XML files of the following form:
<?xml version="1.0" encoding="UTF-8"?>

<c2>8.0</c2>
<c3>9.0</c3>
</eb>
<eb>
<c1>7.0</c1>
... etc ...
</ea>
</root>
Every document has about 50.000 <eb> elements and I loaded 6 sample documents.
A simple query like the following takes about 5 minutes:
SELECT XMLQuery('

Note with DOM Fidelity disabled on all types the SYS_XMLCONV is replaced with the more efficeint SYS_XMLGEN. However this is still not as efficient as the XMLTable approach..

XML binary storage format impairs schema validation?

I'm using Oracle 11g R1 on Windows Server 2003. I successfully registered schemas and created tables and indexes in the new binary storage format. However, when trying to load data, I'm running into problems. Schema validation behaves as if not the full feature set of XML Schema mysteriously isn't supported anymore.
There is probably more but at least wildcard elements (xs:any) and element references (xs:element ref="STH") are simply ignored in the schema definition and data is rejected even when it conforms to the schema.
Is there any solution for this or am I out of luck? I wanted to go back to CLOB storage as used in a previous installation but I'm running into problems when registering the schema. It complains about an empty SQL name although I don't have any defined. I'm pretty weirded out by all this.
I created the schema and table in a straightforward way:
begin
dbms_xmlschema.registeruri(
    schemaurl => 'http://www.xxxhello.com/archive_tsd.xsd',
    schemadocuri => '/public/user/archive_tsd.xsd',
    gentypes => FALSE,
    options => DBMS_XMLSCHEMA.REGISTER_BINARYXML
end;
CREATE TABLE archive OF xmltype XMLTYPE STORE AS binary xml XMLSCHEMA
"http://www.xxxhello.com/archive_tsd.xsd" ELEMENT "CompleteDocument";
create index idx_lastmodified_archive on archive t
(extractvalue(VALUE(t),'/CompleteDocument/DocContent/LastModified'));Because of xs:any or element references is ignored, I get errors like
LSX-00213: only 0 occurrences of particle "REFDELEM", minimum is 1.
Thanks for your help.

The schema is very large (>200kb). Where should I upload it or can I send it to you? I'm bit concerned about confidentiality of company data. However, the instance is not valid yet. I'm in the process of modifying the schema to match all instances, but it breaks on places that should be already okay. No, I didn't use SchemaValidate ever.
But I've made an example where at least xs:any doesn't work. Element references work, though.

Reregister modified XML Schema

I have some XML Schemas registered with my oracle 10g database. The types are created, but not the tables.
Now I have a change in field length in one of the Schemas and I need to reregister it. All the other schemas are dependent on this modified schema.
I used the following approach to delete the schema and register it.
dbms_xmlschema.deleteschema(schemaurl => 'my url',
delete_option => dbms_xmlschema.DELETE_CASCADE_FORCE);
dbms_xmlschema.registerschema(schemaurl => 'my url',
schemadoc => BFILENAME(SCHEMADIR, 'schema_name'),
local=>true,
genTypes=>true,
genbean=>false,
genTables=>false,
force=>false);
This successfully registered the schema.
But whenever the database is restarted, I face a dangling ref error whenever I try to access the OOT created for the Schema.
Any pointers on this will be of great help. Is this the right approach?
Also I read about dbms_xmlschema.copyevolve() procedure. I only need the types, so I am not interested in any transformations as I dont have any instance documents.

The last problem regarding dangling ref's on this forum ended up in creating an SR with support...
Before you register the schema you could set an event that will trace all statements that are executed in the "background" and stored in a trace file in the UDUMP directory
ALTER session SET events = '31098 trace name context forever';It is also always useful to check the database alert.log for errors...

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.

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

You 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...

ORA-30937 when validating element referenced from included schema

I've boiled my latest problem down to a simple test case. Basically it seems as though the included schema is the problem, but I can't figure out why:

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?

I can't register the XML Schemas with XML DB, since we do think versionfiltered is a valid attribute for a schema element...

Bug in xs:pattern implementation when calling schemaValidate?

Hi all,
I have a schema with a pattern <xs:pattern value="(0?[1-9]|1[0-2])"/> that is supposed to validate the digits 01-09, 1-9, 10, 11, 12. When validating XML against the schema, values such as '12' fail. If the xs:pattern in re-written "(1[0-2]|0?[1-9])", i.e. the parts either side of the | are swapped, the xs:pattern works as expected, i.e. '12' validates as correct. The pattern itself works as expected with validators such as with Eclipse, and the RE seems to work as expected in PL/SQL
Is this a bug with the XML parser used in "Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production", or is there another parser I can configure 10g to use? I have a number of xml schemas and patterns to check, and want to be sure that they work as expected.
thanks
Paul

end;
/

Please patch one fo your machines to 10.2.0.3 and then try and duplicate. You do not have to go through the complete registration of the XSD process thoguh you can check and see if the c based parser will validate on the command line using the
schema executible under your oracle_home bin directory.
schema 1.xml 1.xsd
for example
if it dupes in 10.2.0.3 open a TAR with support so that we may bug it.

Unable to register XSD into Oracle using trigger / procedure

Hi,
I am using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production.
I have a table which stores XSD and i need to register this XSD. I am able to register the XSD if dbms_schema is executed from PLSQL anonymous block. But if i mention the same code in trigger / procedure is not working . Getting the error as insufficient privileges.
Table, trigger and procedure are in same schema. This schema has all the privs required for XSD registration globally.

Thanks everyone. I got the solution from one of my colleague. I can invoke dbms_xmlschema.registerschema through my standalone procedure by using current_user authid.
create or replace procedure prc_reg_xsd
(in_id IN NUMBER
, in_xsd IN XMLTYPE)
authid current_user
as
begin
dbms_output.put_line (' startd');
BEGIN
dbms_xmlschema.deleteschema (
schemaurl => in_id
, delete_option => dbms_xmlschema.delete_cascade_force
EXCEPTION
WHEN OTHERS
THEN
dbms_output.put_line (' Failed'); -- This XSD was not registered
END;
dbms_xmlschema.registerschema (schemaurl => in_id
, schemadoc => in_xsd
, local => false);
dbms_output.put_line (' done');
end;
DECLARE
x number:=9;
t xmltype := XMLTYPE(
'<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:books" xmlns:bks="urn:books">
<xsd:element name="books" type="bks:BooksForm"/>
<xsd:complexType name="BooksForm">
<xsd:sequence>
<xsd:element name="book" type="bks:BookForm" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="BookForm">
<xsd:sequence>
<xsd:element name="author" type="xsd:string"/>
<xsd:element name="title" type="xsd:string"/>
<xsd:element name="genre" type="xsd:string"/>
<xsd:element name="price" type="xsd:float"/>
<xsd:element name="pub_date" type="xsd:date"/>
<xsd:element name="review" type="xsd:string"/>
</xsd:sequence>
<xsd:attribute name="id" type="xsd:string"/>
</xsd:complexType>
</xsd:schema>');
BEGIN
prc_reg_xsd(x,t);
END;
This worked for me. The procedure is in the same schema which has XDBADMIN role. So i am able to register the XSD.

Invalid objects and ORA-00600 after deleting XML schema

I am running Oracle 10.2.0.3 on Solaris 10. I am new to XML DB but my developers requested it for a new application. Recently we have noticed the following issue:
My developers have attempted to re-register several schemas using:
DBMS_XMLSchema.deleteSchema(SchemaURL => l_strSchemaURL,
Delete_Option => DBMS_XMLSchema.Delete_Cascade_Force);
And then re-register.
DBMS_XMLSchema.RegisterURI( SchemaURL => l_strSchemaURL,
SchemaDocURI => l_strImportURL,
Local => True,
GenTypes => True,
GenBean => False,
GenTables => True,
Force => False,
EnableHierarchy => DBMS_XMLSCHEMA.ENABLE_HIERARCHY_RESMETADATA);
Afterwards I have noticed several invalid objects:

I opened a TAR with oracle but they have not made much headway. Are we attempting to de-register the schemas improperly? Has anyone seen this issue before?
Thanks,
Brian

SR 6204906.993. Up to this point oracle was able to help me identify that the invalid objects were related to the ORA-00600 but it was just recently that it appeared the Issue was possibly related to the delete schema procedure. The informed me that they were not aware of any known issues with this procedure.
Thanks

Removing xml schema fails

When i try to remove an xml schema using the enterprise manager (10.1.0.2.0) console i receive the following error:
VB0-8051: ...
ORA-31000: Resource ... is not an xdb-schema document
ORA-06512: in XDB.DBMS_XMLSCHEMA_INT: row 70
ORA-06512: in XDB.DBMS_XMLSCHEMA: row 103
ORA-06512: in row 1
Thanks for any hint,
Christian
What i see in the schema code (see below) is that the <xs:schema>-tag is directly following the comment.
Even if i register a schema without a comment, i can't remove it from xdb :-((((

Christian,
I run the following code from sql to remove the schemas I register.
I've noticed when I try to register schemas multiple times I will get errors.
I got this code from one of the XML documents or XDB documents. I don't remember where I found it. You may be able to do a search if you want more information.
declare
unregistered_schema exception;
PRAGMA EXCEPTION_INIT( unregistered_schema -31000 );
begin
dbms_xmlschema.deleteschema('schemaregisterednamehere',dbms_xmlschema.DELETE_CASCADE_FORCE);
exception
when unregistered_schema then
null;
end;

Column int_objname empty after register schema

Hi all,
We have come across a very strange feature in our XDB repository (RDBMS 10.2.0.2 EE) and I hope someone can give a hint to solve it.
In the past we registered xml schemas and worked with it with success. The schemas are local. Now, we're implementing new versions of these xml schemas by deleting the old ones and registering the new versions. But, when we try to delete the old xml schemas, ORA-31000 is the result:
begin dbms_xmlschema.deleteschema ('budget-canoniek.xsd', dbms_xmlschema.delete_cascade_force ); end
ERROR at line 1:
ORA-31000: Resource 'budget-canoniek.xsd' is not an XDB schema document
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 82
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 102
ORA-06512: at line 1However, all_xml_schemas shows that the schema does exists:
1 select owner, schema_url, int_objname
2    from all_xml_schemas
3* where schema_url like '%canoniek%' and local = 'YES'
puc@PGIO> /
OWNER      SCHEMA_URL                INT_OBJNAME
PUC        budget-canoniek2.xsd      XDLTCTsQgnhyHgQPwK+fx/kQ==
PUC        budget-canoniek.xsdTo test what is happening I registered a schema under another name : budget-canoniek2.xsd. This schema can be unregistered without any problems.
The difference between both schemas is a missing value INT_OBJNAME.
Questions:
- Does anyone have a clue how can this int_objname get nullified? I guess some internal process is doing this?
- Does anyone have a clue how we can get this column fixed and filled again. Apparently, this column causes the dbms_xdb.deleteSchema procedure to fail. It also causes other functions on this schema to fail.
- In thread Error when deleting schema the same issue was "solved" by deleting a record in xdb$schema table, but was not recommended. An aternative was not given. Before I totally wreck up my XDB by executing this delete statement: is there an alternative?
Please help,
Regards,

Harm, could you request the backport via metalink? An upgrade to 10.2.0.3.0 will not be a solution, just checked on metalink
I will install it on Thursday (tomorrow I am off to a client) for the project if it is available for download.

Duplicate entries in referenced table (SQLInline=false)

Hi,
I'm testing with the following example XSD from Oracle:

begin
-- dbms_xmlschema.deleteSchema('http://xmluser.de.oracle.com/xsd/deptemp.xsd', dbms_xmlschema.DELETE_CASCADE_FORCE);
dbms_xmlschema.registerSchema('http://xmluser.de.oracle.com/xsd/deptemp.xsd', doc, TRUE, TRUE, FALSE, TRUE);
end;
Whenever I insert a line into the DEPT_TAB created by the above example, I get two entries for any contained Employees element in the EMPLOYEES_TABLE.
E.g. the EMPLOYEES_TABLE is empty:
SQL> select * from EMPLOYEES_TABLE;
No rows selected.
Then I insert the following:
SQL> insert into DEPT_TAB VALUES (sys.XMLType('
<depttable xmlns:xdb="http://xmlns.oracle.com/xdb" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmluser.de.oracle.com/xsd/deptemp.xsd">
     <Deptno>1</Deptno>
     <Deptname>Sales Consulting</Deptname>
     <Employees>
          <Name>ABC</Name>
          <Age>11</Age>
          <Addr>
               <Street>Street1</Street>
               <City>City1</City>
          </Addr>
     </Employees>
     <Employees>
          <Name>DEF</Name>
          <Age>22</Age>
          <Addr>
               <Street>Street2</Street>
               <City>City2</City>
          </Addr>
     </Employees>
</depttable>
After this I find the following in the EMPLOYEES_TABLE:
SQL> select * from EMPLOYEES_TABLE;
SYS_NC_ROWINFO$
<Employees>
<Name>ABC</Name>
<Age>11</Age>
<Addr>
<Street>Street1</Str
<Employees>
<Name>DEF</Name>
<Age>22</Age>
<Addr>
<Street>Street2</Str
SYS_NC_ROWINFO$
<Employees>
<Name>ABC</Name>
<Age>11</Age>
<Addr>
<Street>Street1</Str
<Employees>
<Name>DEF</Name>
<Age>22</Age>
<Addr>
SYS_NC_ROWINFO$
<Street>Street2</Str
SQL> select count(*) from EMPLOYEES_TABLE;
COUNT(*)

What's wrong here?
Thanks for your help,
Andreas

Physical design is different depending on the DB, so let's start there, e.g. the Dim tables have unique indices built on the DIM IDs, but in Oracle - the fact table (Non-transactional and no Line Item/High cardinality dims) would just have bitmap indices, so not having a unique index on the fact table is not an issue in Oracle.
What DB and version?
Do any of the Dims have more than 16 charateristics in them?
Are there concurrent loads to the InfoCube from different data sources?
Is Number Range buffering used for any of the dimensions?
Key figure(s) identical values, or are they different?
