Tips and Techniques: Install and Configure Oracle9i on Red Hat Linux
Advanced Server
EXECUTIVE OVERVIEW
Red Hat Linux Advanced Server is an enterprise ready platform,
borne out of feedback and close collaboration between the
engineering teams from Oracle and Red Hat. With features like
large memory support, lower mapped base support for process,
shared memory file system (shmfs), high page table entry (pte)
fix, asynchronous I/O support, bigpages feature and greedy swap
patch, Red Hat Linux Advanced Server is a robust product.
The key to successful installation and deployment of Oracle9i
Database Release is proper installation of the operating system.
Careful installation and tuning of Red Hat Linux Advanced
Server would make deployment of Oracle9i database an easier
task.
The objective of this paper is to help resolve common issues in
the installation of Oracle9i Database Release 2, and to provide
tips on various kernel parameters for Red Hat Linux Advanced
Server, that would eventually help in tuning database server.
Various debugging tools and techniques are discussed.
