oracle? need help with installation

[Zbigniew Koziol]

Ok, so will have some additional comments to these letters.

First, regarding why I need oracle. Sure, I like postgres, I love it,
not like only. But sometime we are forced to use software that
otherwise we would prefer not to use. Simply, I am in a contact with
people from a Very Huge Company who do quite significant development
of Oracle itself. The company is from GIS industry, which is
attractive to me (there is shortage of of specialists in GIS
worldwide, and I do have basic experience in that field, equired in my
latest workplace). So, I simply want to try that opportunity as
possible direction in my future carrier.

Oracle has Oracle Spatial addition, which is largely regarded as a
kind of standard in GIS industry. I know, postgreSQL also has GIS
extension, which is very powerful. But thats not me who decides what
to use.

Oracle has also Map Viewer. Oh, well, I did hear that it does not work
very well, but I am very curious how it is designed, because I
programmed one myself working on Firefox, and there is possibly a lot
of interesting technology around that is related to the subject.

Besides all that, I am simply curios, I want to see how similar or
different are both database servers.

Yes, documentation exists to Oracle. Here is a link to one of documents:
http://download.oracle.com/docs/cd/B25329_01/doc/install.102/b25144/toc.htm

However, it is silly documentation. It uses language more like for
Microsoft products. Reading that just irritates me. May be I could
swallow it, but the point is that the documentation does not discuss
all possible problems that may happen around.

I am on Centos , 2.6.18-92.1.10.el5 , so it seems that a RedHat
version of their installation should work right away.

After installation I do have  listener working (again, I had for that
to create my own /etc/init.d script, which seems somewhat silly; why
wouldnt they prepare one?)

But I have no access to administrative web interface. And why? I have
no idea. It simply does not start. Log files are short and contain for
instance the following crap (what an insane path to log file!):

/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/log/localhost/client/css.log

What is that OCR? No, googling did not help me much...
