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.
