a user wanted to use utl_inaddr.get_host_name but got an error regarding network acl permissions, so I tried granting them as such:

SQL> begin
2 DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('somename.xml',
3 'somecomment',
4 'SOMEUSER', TRUE, 'connect');
5 DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('somename.xml',' *');
6 end;
7 /

But I keep getting this response:
ERROR at line 1:
ORA-31003: Parent /sys/acls/ already contains child entry somename.xml
ORA-06512: at "XDB.DBMS_XDB", line 192
ORA-06512: at "SYS.DBMS_NETWORK_ACL_ADMIN", line 195
ORA-06512: at line 2

However, I cannot see this when I do

SQL> select * from dba_network_acls;

no rows selected

I've tried reading the docs here http://download.oracle.com/docs/cd/B...n.htm#BABJJBJI
but haven't figured this out yet. I tried the dba how to see network acls thing but that also returned no rows.

I don't understand why I can't create this acl and also cannot see it.

Can anyone point me in the right direction?
