Deploying Oracle data on the web

Oracle Tips by Burleson Consulting

Now that mainstream American business is internet-enabled, midcaps and small businesses are exploring methods for deploying their data over the web. For a typical example, retail companies are driven to give their customers real-time access to order and shipping information, but they don't want to hook-up their server to the internet.  Why take the risk?

What tools for deploying Oracle data?

There are many ways to get Oracle data on the web, just to name a few:

There are also third-party tools that deploy Oracle data over the web:

Safety First

With all these choices, what's a company to do?  The answer is always "safety first", use a solution that will not expose your central server to attack.  Such a solution would have a remote webserver running Oracle XE, totally disconnected from the main database.  Your production database simply streams updates to a known-internet port for the XE database, with no backward connections possible.

No storm in the port

Hackers are persistent and an FBI field agent once told me that a determined hacker can crack and system, given enough time. 

All they need is an internet port.  Any server that has an internet port is a target for hackers, and the only safe solution is an asynchronous data deployment method to a remote server, completely disconnected from the mission-critical computing environment.  Oracle has graciously provided the license-free Oracle XE database, which has APEX and makes the ideal environment for web-enabling Oracle data (Note that Oracle XE has limits, and you must have a database < 4 gig and only run one CPU).

Many companies are taking baby steps into the internet by deploying customer information periodically, leaving the remote Oracle database (the one that's connected to the Internet), read-only except when it's being refreshed.

One ideal solution is to use Oracle replication (snapshots or Oracle Streams).  With Oracle replication, your secure server only opens it's port for a very brief period of time as it blasts any table changes to the internet copy of Oracle.  The internet server has a process listening for refreshes, but the remote Oracle cannot connect back to the sending database.  If a bad guy hacks into the internet Oracle system, there is nothing that points back to your mission-critical environment.
 
I have implemented this for many clients, and BC provides complete support consulting for deploying your Oracle data.  Just call if you want help.

 

If you like Oracle tuning, you may enjoy my new book "Oracle Tuning: The Definitive Reference", over 900 pages of BC's favorite tuning tips & scripts. 

You can buy it direct from the publisher for 30%-off and get instant access to the code depot of Oracle tuning scripts.
