Oracle Base System Installation

Unfortunatly i have not got the actual oracle installers going but this will setup the base system so that the oracle installer should go through without issues.

Package Configs

Firstly you need a copy of libaio. You can google for the deb package. I installed this on my private debian mirror

package_config/ORACLE

PACKAGES install
binutils
libdb2
libdb3
libdb4.1
libdb1-compat
cpp-3.3
gcc-3.3
libstdc++5-3.3-dev
libstdc++2.10-glibc2.2
base-files
netbase
libc6
libc6-dev
make
vncserver
libaio
gcc

Scripting

The following is used to setup the various parts of the system so that the oracle installer will work without problems.

Init Script

The init script is copy'd using fcopy during the script phase of the installation. Below is the init script used to start oracle
