Novell® IS&T Beige Paper
Implementing Oracle 11i Applications on SUSE Linux Enterprise Server – What We Did and How We Did It

Here’s an Excerpt:

Abstract: A Successful Upgrade

Novell recently completed its upgrade from
Oracle* 11.02 to Oracle 11i. As part of the
process, many individual and independent
systems became part of the upgraded Oracle
system. We achieved the following objectives:

  • Moved all tiers of our Oracle E-Business Suite to SUSE? Linux Enterprise Server on commodity hardware
  • Improved availability and scalability with RAC
  • Provided database and application management and redundancy with PolyServe
  • Implemented user provisioning with Novell? eDirectory? and Novell Identity Manager
  • Provided single sign-on with Novell iChain?
  • Implemented load balancing via L4 switches

We started with an 18-processor server for
the database and three four-processor servers
for the mid-tier, and we moved to commodity
(off-the-shelf) HP* machines. We now run
Oracle on less expensive hardware and incur
less expense for support contracts, saving
us hundreds of thousands of dollars in hardware
and support costs alone. Our recovery
time improved significantly:

  • Recovery Point Objective (RPO):

    from one week to one day
  • Recovery Time Objective (RTO):

    from 72 hours to less than four hours

We made no changes in the number of personnel.
Most important of all, our system is
highly redundant with greater than 99-percent
uptime and availability.

This paper briefly describes our processes, the
components we used, what functionality they
provide, and the reasons they were chosen.
