XML Schema registration error

Question

We installed XMLDB on Oracle Server Enterprise Edition 9.2.0.3 (AIX 4.3 version).
The status from DBA_REGISTRY for Oracle XML DB is VALID.
When trying to register schema, we get following error:
ERROR at line 1:
ORA-01031: insufficient privileges
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 0
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 12
ORA-06512: at line 35
Here are the steps:
1. Connect as SYS
2. grant xdbadmin to wb_interface;
3. connect as wb_interface;
4. Try to register schema as follows
declare
doc varchar2(1000) := '<schema
targetNamespace="http://www.oracle.com/PO.xsd"
xmlns:po="http://www.oracle.com/PO.xsd"
xmlns="http://www.w3.org/2001/XMLSchema">
<complexType name="PurchaseOrderType">
<sequence>
<element name="PONum" type="decimal"/>
<element name="Company">
<simpleType>
<restriction base="string">
<maxLength value="100"/>
</restriction>
</simpleType>
</element>
<element name="Item" maxOccurs="1000">
<complexType>
<sequence>
<element name="Part">
<simpleType>
<restriction base="string">
<maxLength value="1000"/>
</restriction>
</simpleType>
</element>
<element name="Price" type="float"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
<element name="PurchaseOrder" type="po:PurchaseOrderType"/>
</schema>';
begin
dbms_xmlschema.registerSchema('http://www.oracle.com/PO.xsd', doc);
end;
Please Help!!!

Answer 1

check if the user already has the following privileges.
CREATE SESSION
CREATE TABLE
CREATE TRIGGER
CREATE TYPE
ALTER SESSION
Else grant them.
The problem only comes when use do this in pl/sql.
here is a work around example.
create or replace function get_xml_data return varchar2 is
doc varchar2(1000) := '<schema
targetNamespace="http://www.oracle.com/PO.xsd"
xmlns:po="http://www.oracle.com/PO.xsd"
xmlns="http://www.w3.org/2001/XMLSchema">
<complexType name="PurchaseOrderType">
<sequence>
<element name="PONum" type="decimal"/>
<element name="Company">
<simpleType>
<restriction base="string">
<maxLength value="100"/>
</restriction>
</simpleType>
</element>
<element name="Item" maxOccurs="1000">
<complexType>
<sequence>
<element name="Part">
<simpleType>
<restriction base="string">
<maxLength value="1000"/>
</restriction>
</simpleType>
</element>
<element name="Price" type="float"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
<element name="PurchaseOrder" type="po:PurchaseOrderType"/>
</schema>';
begin
return doc;
end;
exec dbms_xmlschema.registerSchema('http://www.oracle.com/PO.xsd', get_xml_data);
good luck.
