Oracle installation script for Linux

# Scripts are only used for communication and learning!

# The current script version is 1. 0. implements the detection of physical memory and swap space. The RPM package is automatically installed (you need to configure Yum or attach the disc. If you have copied all the required RPM packages to a directory, OK .), user and User Group Creation, software environment variable configuration, system kernel parameter configuration, and other functions. after the script is successfully executed, decompress the Oracle Installation Package and enable the graphical installation of runInstaller. # The script has passed the test on Red Hat Enterprise Linux 5.4 64bit (Oracle 10g/Oracle11g ). it is applicable in principle to RHEL 5 and RHEL 6. # suggestions for improvement are welcome.

# Scripts can be downloaded through attachments
