When you install DBPrism CMS at installation time there are parameters which define where a deployment Web Site will be deployed.

These parameters affect where ESI invalidation messages are sent when a public page was changed. If you perform a new deployment web site with a new IP address or port is necessary to grant a connect resource to the new location into the ESI access list.

Perform this SQL command logged as SYS:

SQL> exec DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('acl_for_cms.xml', 'newserver', newport);
SQL> commit;

Now Oracle database is able to sent ESI invalidation messages to a new deployment web site.

Finally you can update using DBPrism CMS Front End using a menu option USERNAME->User's Preference the information relative to Deployment Web Host and Deployment Web Port.
