Hi all,

As I am using UTL_HTTP package, I am required to provide access using dbms_network_acl_admin.create_acl
But I am confused in providing value for argument 'host' in dbms_network_acl_admin.assign_acl
I had executed pl/sql block like
SQL> ed
Wrote file afiedt.buf

  1  begin
  2    dbms_network_acl_admin.assign_acl (
  3    acl => 'utlpkg.xml',
  4    host => '*',
  5    lower_port => 1,
  6    upper_port => 10000);
  7* end;
SQL> /

PL/SQL procedure successfully completed.

SQL> select host, lower_port, upper_port, acl, aclid
  2  from dba_network_acls
  3  where ACL='/sys/acls/utlpkg.xml';

HOST
--------------------------------------------------------------------

LOWER_PORT UPPER_PORT
---------- ----------
ACL
--------------------------------------------------------------------

ACLID
--------------------------------
*
         1      10000
/sys/acls/utlpkg.xml
43748F35D57D4372805BAED3A9978D0F


This is because I am required to access any website using UTL_HTTP package.

But while executing

DECLARE
  P_URL_I VARCHAR2(200);
  P_LINK_I VARCHAR2(200);
  v_Return BOOLEAN;
BEGIN
  P_URL_I := 'http://www.toppica.com/submit.php';
  P_LINK_I := 'www.xlntseo.com';

  v_Return := SEO_VERIFICATION.VERIFY_LINK(
    P_URL_I => P_URL_I,
    P_LINK_I => P_LINK_I
  );
  IF (v_Return) THEN 
    DBMS_OUTPUT.PUT_LINE('v_Return = ' || 'TRUE');
  ELSE
    DBMS_OUTPUT.PUT_LINE('v_Return = ' || 'FALSE');
  END IF;
END;

ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1674
ORA-24247: network access denied by access control list (ACL)
ORA-06512: at "XLNTSEO.SEO_VERIFICATION", line 8
ORA-06512: at "XLNTSEO.SEO_VERIFICATION", line 30
ORA-06512: at line 9
29273. 00000 -  "HTTP request failed"

regrds,
Delna

I can honestly say that I've never even heard of the packages that you're using here.

Any chance of a 5 line summary of what they're used for?

Quote:
The DBMS_NETWORK_ACL_ADMIN package provides the interface to administer the network Access Control List (ACL).


Database Security Guide
Chapter 4 Configuring Privilege and Role Authorization
Section Managing Fine-Grained Access to External Network Services
Quote:
You can configure fine-grained access control for users and roles that need to access external network services from the database. This way, specific groups of users can connect to one or more host computers, based on privileges that you grant them. Typically, you use this feature to control access to applications that run on specific host addresses.

Quote:
To configure fine-grained access to database network services, you create an access control list (ACL), which is stored in Oracle XML DB. You can create the access control list by using Oracle XML DB itself, or by using the DBMS_NETWORK_ACL_ADMIN and DBMS_NETWORK_ACL_UTILITY PL/SQL packages.
