Oracle Database Discussions

Hi folks,

I installed successfully Oracle 10g r2 on MAC OS X 10.6 (snow leopard) following the instructions found here:
http://blog.rayapps.com/2009/09/14/how-to-install-oracle-database-10g-on-mac-os-x-snow-leopard/

SQL*Plus was working fine right after the installation, even SQL Developer.
After rebooting the computer it appears the following issue:

ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Mac OS X Error: 2: No such file or directory

Here is the informations:
