Severe xml inconsistency

Question

HI gentlemen,
When trying to install basicDemo, I got in a mesh.
- Installing xdbUtility it does not create resource /sys/databaseSummary.xml because it already exists (from a first trial).
- On trying to delete it from Enterprise Manager I receive ORA-942 - not found. However it is listed under resources.
- When I select value(x) from XDB_DATABASE_SUMMARY x, I get reasonable answer, however ...<ServiceName>enable</ServiceName>... is nasty. What is "enable" here and why do I not have a normal construct instead?
- When I type C:\TEMP>lsnrctl status, several other services are listed but not "enable".
- And when I connect through ftp, and then
ftp> get /sys/databaseSummary.xml - this is mad. Again ORA-942.
- Finally, when trying to verify HTTP, ie
http://<myhost>:8080/sys/databaseSummary.xml, the page can not be displayed.
That means, I am fully prevented from exercising with the demo and learning.
Could you please help me a bit, where am I wrong and what to do?
Many thanks, regards from
Miklos HERBOLY
ftp> get /sys/databaseSummary.xml

Answer 1

login to the database using sql*plus with SYS user with SYSDBA privileges and issue.
dbms_xdb.deleteresource('/sys/databaseSummary.xml', 4)
this is force delete option.
then execute the below
create or replace view XDB_DATABASE_SUMMARY of xmltype
with object id
substr(extractValue(sys_nc_rowinfo$,'/Database/@Name'),1,14)
as select xmlelement
             "Database",
             XMLAttributes
                x.NAME as "Name",
                extractValue(config,'/xdbconfig/sysconfig/protocolconfig/httpconfig/http-port') as "HTTP",
                extractValue(config,'/xdbconfig/sysconfig/protocolconfig/ftpconfig/ftp-port') as "FTP"
             XMLElement
                "Services",
                (Select XMLAGG
                           XMLForest(Value as "ServiceName")
                 From V$SYSTEM_PARAMETER
                 WHERE NUM = 491
             XMLElement
                "Hosts",
                (Select XMLAGG
                           XMLForest(HOST_NAME as "HostName")
                 From V$INSTANCE
FROM V$DATABASE x, (select dbms_xdb.cfg_get() config from dual)
declare
res boolean;
-- dbref ref xmltype;
   dbxml xmltype;
begin
   begin
     dbms_xdb.deleteResource('/sys/databaseSummary.xml');
   exception
     when others then
       null;
   end;
   select value(x)
   into dbxml
   from xdb_database_summary x;
   res := dbms_xdb.createResource('/sys/databaseSummary.xml',dbxml);
end;
select xdburitype('/sys/databaseSummary.xml').getClob() from dual
Check for the output here itself. Once your view creation is successful even you http should go through.
