Oracle installer doesn't work on FC8. The problem is in the new libX11
which is rather buggy when using the new XCB binding mechanism. The error
produced by installer is the following:


java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.

Fiddling with the different versions of Java will not help and neither
will the "sed trick" which replaces the codec name in the Athena widget
library. The only thing that will help is to replace the libX11 packages

libX11-devel-1.1.3-4.fc8
libX11-1.1.3-4.fc8

with the FC7 versions:
libX11-1.0.3-8.fc7
libX11-devel-1.0.3-8.fc7


Of course, during that operation X11 cannot be active. Bug is well
reported on Fedora and affects most of the Java based tools. Netmgr is
also affected:

[oracle@mladen ~]$ netmgr
java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
/oracle/product/10.2.0/bin/netmgr: line 161: 4225
Aborted $JRE -
Dsun.java2d.font.DisableAlgorithmicStyles=true -mx100m -classpath
$CLASSPATH oracle.net.mgr.container.NetApplication
oracle.net.mgr.container.NetApplication
[oracle@mladen ~]$

In other words, if you are using Java, do not upgrade to FC8:

[mgogala@mladen ~]$ uname -a
Linux mladen 2.6.23.1-49.fc8 #1 SMP Thu Nov 8 21:41:26 EST 2007 i686 i686
i386 GNU/Linux
[mgogala@mladen ~]$

Scrap Java, use Perl.

There are workarounds available. I don't approve of one of them in
particular: you just hack the Oracle-supplied JRE. A rather more
sensible workaround (untested by me) involves setting nothing more
than an environment variable -viable if it works. Details on the blog
at www.dizwell.com

But to be frank, anyone contemplating running on Fedora 8 wants their
head tested.

Use Centos instead (or even, if you have to be cutting edge, Ubuntu or
Suse: both work fine without hacks, workarounds or botch-jobs).

I had a haircut last Saturday. Does that count as a test?

I am using CentOs, but this was just a new laptop that I wanted to play
with. Nothing major, but solving it was interesting.

I agree with this. I always learn ten times what I expected when I
have to "get something to work", especially on my time.
