Using HTTP and HTTPS for Advanced Queuing Propagation
2. Create the dblink with protocol as HTTP and the host and port of the Web
server running the AQ servlet, with the username and password for
authentication with the webserver/servlet runner.
For example, if the webserver is running on the machine
webdest.oracle.com and listening for requests on port 8081, then the
connect string of the database is as follows:
(DESCRIPTION=(ADDRESS=(PROTOCOL=http)(HOST=webdest.oracle.com)(PORT=8081))
If SSL is used, then specify HTTPS as the protocol in the connect string.
The database link is created as follows:
create public database link dba connect to john identified by welcome using
'(DESCRIPTION=(ADDRESS=(PROTOCOL=http)(HOST=webdest.oracle.com)(PORT=8081))'
;
Where user john with password welcome is used to authenticate with the Web
server and is also known by the term AQ HTTP agent.
3. You can optionally set a proxy to use for all HTTP requests from the database.
Use the UTL_HTTP.SET_PROXY procedure, as described in Oracle9i Supplied
PL/SQL Packages and Types Reference.
4. If HTTP over SSL is used, then a database wallet must be created for the source
database. The wallet must be open for the duration of propagation. If HTTPS is
used for propagation, communication between the source database and the AQ
servlet is encrypted and the HTTPS server is authenticated with the source
database. The database uses the database link username-password to
authenticate itself with the HTTPS server.
5. Deploy the AQ Servlet.
Create a class AQPropServlet that extends AQxmlServlet as described in [create
the AQ XML Servlet Class]. This servlet must connect to the destination
database. The servlet must be deployed on the Web server in the path
aqserv/servlet.
In Oracle9i, the propagation servlet name and deployment path are fixed; that
is, they must be AQPropServlet and the servlet, respectively.
6. Make sure that the AQ HTTP agent (John) is authorized to perform AQ
operations. This is done at the destination database:
a. Register the AQ agent as follows:
dbms_aqadm.create_aq_agent(agent_name => 'John', enable_http => true);
