2. install necessary software packages
There are not many software packages required for the 11g, as long as you install build-essential, rpm, libaio, KSh, libtool, libstdc ++ 5
Sudo apt-Get install RPM libaio1 KSh libtool libstdc ++ 5 build-essential
3. Set the directory structure and symbolic link
Sudo ln-S/usr/bin/awk
Sudo ln-S/usr/bin/RPM
Sudo ln-S/usr/bin/basename
Sudo mkdir/etc/rc. d
For I in 0 1 2 3 4 5 6; do ln-S/etc/rc $ I. d/etc/rc. d/RC $ I. D; done
Create two directories under the "/OPT" directory "/opt/oracle11g/Server", "/opt/oracle11g/oradata", and "server" to store 11G program files, "oradata" is used to store database files. Here, luyaowei is the user name for logging on to your system.
Sudo mkdir/opt/oracle11g
Sudo mkdir/opt/oracle11g/Server
Sudo mkdir/opt/oracle11g/oradata
Sudo chown luyaowei/OPT
Sudo chown luyaowei/opt/oracle11g
Sudo chown luyaowei/opt/oracle11g/Server
Sudo chown luyaowei/opt/oracle11g/oradata
