Introduction
This paper studies the Oracle Cluster File System Release 2 (OCFS2) for Linux® on IBM® System z®, based on an implementation of OCFS2 in a test lab environment, for a clustered database.
The name 'OCFS2 study' is used in place of the full name 'OCFS2 Version 1.2 shared file system for Linux on IBM System z' for the remainder of this document.1
Novell SUSE Linux Enterprise
Server (SLES) 10 SP1 on an IBM System z10™ is used. The intent
is to provide insight for an enterprise customer who is considering
using the OCFS2 shared file system in an IBM System z environment. The following IBM System z features are discussed, in terms
of how they relate to OCFS2:
- Servers in LPARs
- HiperSockets™ connections
- Disk storage on large external storage units
This paper is organized into these sections:
1 This paper is intended to provide information regarding
OCFS2. It discusses findings based on configurations that were created
and tested under laboratory conditions. These findings may not be
realized in all customer environments, and implementation in such
environments may require additional steps, configurations, and performance
analysis. The information herein is provided “AS IS“ with no warranties,
