Download Software

Download the following software.

Unpack Files

Unzip the files.

unzip 10201_database_linux32.zip

You should now have a single directory containing installation files. Depending on the age of the download this may either be named "db/Disk1" or "database".

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.

For example.

127.0.0.1      localhost localhost.localdomain192.168.0.198  ol5-102.localdomain ol5-102

#kernel.shmall = 2097152#kernel.shmmax = 2147483648kernel.shmmni = 4096# semaphores: semmsl, semmns, semopm, semmnikernel.sem = 250 32000 100 128#fs.file-max = 65536net.ipv4.ip_local_port_range = 1024 65000net.core.rmem_default=262144net.core.rmem_max=262144net.core.wmem_default=262144net.core.wmem_max=262144
