Currently we have installed apex 3.2 in our production system. Both the Oracle HTTP Server (Apache) and the Db reside on same server as such they are on the external DMZ. Security issue has been raised for this as the Database is exposed to external world. Requirement is that Apache should be on external DMZ and the Db should be in the internal DMZ. Is it possible to seprate both layers on different servers.
Can I have only the OHS on one server and Db on another.Yes, but it incurs additional licensing costs. OHS is free to deploy on the same server as the DB, but not if they are separated.
We are also thinking of moving to Oracle 11g. In 11g there is not need for OHS to be installed separately.If by this you mean you are thinking of using the Embedded PL/SQL Gateway then reconsider: OHS provides better performance and infinitely better features and flexibility.
But as above, we would like to separate Apache and Db in separate DMZ.A frequent solution is to use a standard Apache web server in the external DMZ as a reverse proxy to OHS in the internal DMZ, with OHS and the DB on the same server for licensing reasons.
Can somebody provide help for above....
