Oracle on the Web, Part 2 - Oracle 10g's HTTP Server and HTML DB

By Steve Callan

In part one of this series, the installation and basic configuration of Oracle9i's HTTP Server was covered. This part of the series looks at how the HTTP server has changed with respect to how you get it and how you use it. Part of the process is very easy, and other parts are somewhat confusing. If you were hoping for a clean, "one CD type of install and there it is" situation, the result is a mixed bag.

Framework for getting the 10g HTTP server

Unfortunately, the installation is not just one CD. The HTTP server component, along with other products, is on a companion CD. Oracle10g Standard Edition One and the companion CD, like virtually every other Oracle product, are available at OTN. However, another way you can get the CD set is to ask for the Oracle 10g Resource Kit (click on the advertisement seen on several Web sites is one way).

The kit includes three CDs: one for SE1 (the RDBMS software), a companion CD, and a study guide CD. There is a requirement to register online (the Web address is shown in an OUI window) to receive a registration code, and then you enter the code before OUI will continue.

In case you have not installed 10g yet, the installation footprint is a bit different in terms of what you would expect from OFA standards in the past. Additionally, if the installation s and you need to clean the registry, the "HOME" key begins with "KEY" instead of HOME under HKEY_LOCAL_MACHINE > Software > Oracle.

As another tip, if you encounter a failure related to OracleCSService (the clustering service), the DBCA assistant will fail (which means no database to play with later). Turn off or disable any anti-virus or firewall software, stop any 10g services, delete the files, and clean out what you can from the registry, focusing on the DBConsole and the CSService.

After SE1 is installed, the Enterprise Console will appear. Take a tour of that, and then exit.

Insert the companion CD and start (or autorun) OUI again. This part of the installation requires a separate ORACLE_HOME - by name and location. You can choose either companion products option, but only one at a time. At the "Select a Product to Install" window, pick the bottom option to get the two items of interest for later on: Oracle HTTP Server and HTML DB.

Tip: Do not have TNS_ADMIN set because a net configuration assistant creates its own tnsnames.ora file using "HTMLDB" connecting to the name of your target database. If the assistant cannot connect to the HTML DB, the setup will fail.

      (ADDRESS = (PROTOCOL = TCP)(HOST = D2JW5021)(PORT = 1521))
      (SERVICE_NAME = db10)

Be sure to record the password for the HTML DB DBA.

Take note of the URIs at the end of the installation. More than likely, the port will be 7777.

What makes the HTTP server so important is that it is your gateway to the HTML DB - which leads to a thought: name as many different types of DBA's you can think of. No doubt, you thought of production, development, applications (as in Oracle Apps), data warehouse, and jobless (ouch!). It is time to add one more type to the list, and that is the HTML DB DBA.
