In my previous blog entry, I explained why I would expect Result Cache not to scale well. Unfortunately, at the time that blog entry was written, I had no access to hardware with more than two cores. That left me in an everything-but-the-proof state. Since then, I got a chance to re-run my test cases on a quad-core CPU, moving one step forward. Here is what I got:
Apparently somebody who reads blogs regularly found one that said Fedora 8 bombed because he couldn’t install oracle on it. So I took on the challenge. I have to say installing Fedora 8 was the most difficult part of the challenge. The workaround given is to patch the libmawt.so with sed (!). The link in this post has all the gory details, but how do you do it for the oracle installer? The jre is compressed and there is no libmawt.so or any other .so to be found.. Here’s how in a nutshell…
Welcome to the 70th edition of Log Buffer, the weekly review of database blogs.
Thinking I had something new, I wrote this article about recovering deleted files. However, it turns out Frits Hoogland had already blogged about recovery of deleted files on linux, as Frits pointed out in a comment on my blog, where he also mentioned a metalink note on this matter. The procedure outlined in the note describes how to recover the deleted file and put it in the same location as the deleted file. The problem is that it doesn’t include offlining/onlining the file, so the database ends up with two distinct copies of the file.
So you have accidentally removed a datafile from your production database? First thing, DON’T PANIC! There’s an easy way to recover deleted datafiles, for as long as your database remains up. The procedure, outlined here, works on linux, however this method conceivably can work for other platforms.
After many requests from readers, I’ve put together new, revised version of the Oracle 11g on Ubuntu recipe. This new version is a little different than the first one published: it’s based on a bare-bones install of Ubuntu 7.10 (Gutsy Gibbon) server version instead of the desktop version. As an improvement, I’ve tried to pare down dependencies to a minimal set. Your feedback is more than welcome — it’s the main reason why I wrote a new version of this HOWTO. I’ve also tested and repeated this procedure twice. Even so, it might still have problems, so please let me know so we can improve it 1.

I found some interesting software pieces available for download from Oracle TechNet. “Oracle Outside In Technology” represents a set of SDK’s for various content management operations. Basically, those are excellent building blocks for content management applications and tasks. Here are couple descriptions to heat your interest up.
