How to Install Oracle 11g under Linux SUSE

Depends on version of Suse... 11g is only compatible (so far) with Suse Enterprise 10.0

Link is also some general installation instructions: http://download.oracle.com/docs/cd/B28359_01/install.111/b32002/pre_install.htm

I have installed gcc and others using Yast---software management, but still i am unable to run runInstaller command following error occurs:
java: xcb_xlib.c:52: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.

what should i do experts?

What this command do :- I didn't find these files in my system. somebody wrote that if u r not using RAC then do the following.
# /etc/init.d/init.cssd disable
# /etc/init.d/init.cssd stop

I got the solution of above problem, just type export LIBXCB_ALLOW_SLOPPY_LOCK=1 before execute ./runInstaller
