## Oracle 11g XE on CentOS 6 Pitfalls
# Don't trust the fucking manual about minimum requirements.
# You always need 2GB of *swap* space at least and 512MB physical RAM.
# Maybe server can run with less resources, but it fails to create initial database.
# So don't expect it to run on low-end machine.

# Configure hostname properly... Oracle fails if it cannot find the server using hostname.
# Example.
echo "127.0.0.1    oracle11g.local"

# Install requirements properly. Especially, 'bc' is undocumented dependency.
# Versions are all fine. So don't worry.
yum install -y glibc make binutils gcc libaio bc

# Now you're safe to run installaion.
rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm
