Do you know if the stability of these databases and the functionality they provide is at the same level when they are run on Apache or Linux as it is when they are run on Unix or NT? Err... Apache is a web server, not an OS. It runs on Linux, various Unices, and also on NT (or even Win98!). It really doesn't make sense to talk about a database "running on Apache". Although Apache will interface with most databases. I actually wrote an apache module for a company I was working for that authenticated web users directly against a custom database running on Oracle (using OCI). The features of the database will be the same regardless of the OS it is running on, but the stability of the database will be limited to that of the underlying OS. For example, the Solaris version will be more stable than Linux, which will be more stable than NT, etc... The speed of the database will be determined to a large degree on the overhead imposed by the operating system, but can also be affected by whether or not the database uses it's own raw disk partition, or makes use of the underlying OS filesystem. Again, this will vary from database to database, and OS to OS. -Mitch

Eric, I was going to respond to your query, then I read Mitch's response. He is basically right. Apache is a web server, not an operating system. (Other web servers include Netscape Enterprise and Microsoft Internet Information Server, this last, on NT only of course.) Performance of an enterprise DBMS depends on many, many factors. (Critical tuning of this software is an archane and wonderful art.) It's fair to assume that the Linux port of these DBMS have the same feature set as their brethren that run on other flavors of UNIX. In fact, I was told by the developers that did the Linux port at one of the enterprise database companies that all that was involved was taking the source for the version that ran on SCO [the Santa Cruz Operations UNIX flavor], throwing some compiler flags, recompiling, and running it through QA. Hopes this helps, it may be more than you ever wanted to know about the topic... PB
