Register schema: insufficient privileges to use enablehierarchy

Question

Hello,
In Oracle11g release 2 I'm trying to register a schema. It works, as long as I set enablehierarchy to ENABLE_HIERARCHY_NONE.
For all other values of this parameter, I get this error message:
ORA-31061: XDB error: DBMS_XDBZ.ENABLE_HIERARCHY
ORA-06512: at "XDB.DBMS_XDBZ0", line 131
ORA-06512: at "XDB.DBMS_XDBZ0", line 586
ORA-01031: insufficient privileges
ORA-06512: at "XDB.DBMS_XDBZ", line 37
ORA-06512: at line 1
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 55
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 159
ORA-06512: at line 4
for instance, this works:
declare doc xmltype;
begin
select dbms_xmlschema.generateschema(user,'VORM') into doc from dual;
dbms_xmlschema.registerschema('http://www.5hart.com/schema/vormen.xsd', doc,
gentypes => false,
enablehierarchy=>dbms_xmlschema.*ENABLE_HIERARCHY_NONE*);
end;
but this doesn't:
declare doc xmltype;
begin
select dbms_xmlschema.generateschema(user,'VORM') into doc from dual;
dbms_xmlschema.registerschema('http://www.5hart.com/schema/vormen.xsd', doc,
gentypes => false,
enablehierarchy=>dbms_xmlschema.*ENABLE_HIERARCHY_CONTENTS*);
end;
Could someone tell me what privileges I'm missing? I have the role XDBADMIN, I've tried "grant execute on DBMS_XDBZ, but nothing works.
Help would be appreciated.
Thanx,
Marko

Answer 1

Nowadays I can explain why this works - I think.
Locally registered xml schemas are protected by ACL's (more or less) and is accessable ONLY by the user that created it (besides SYS). DBA,XDBADMIN, system accounts etc are just not good enough.
The direct granted "alter session" prevents having to use the full syntax of OWNER.OBJECT_NAME.COLUMN_NAME@DBLINK etc, etc... and thus refering to objects can be reduced to OBJECT_NAME instead of OWNER.OBJECTNAME and makes it possible for the package to do its XDBZ thingy.
