  Oracle Database Tips by Donald Burleson

Oracle10g Grid Computing with RAC
Chapter 5 - Preparing Shared Storage

For Linux and Windows

The OCFS version for Windows NT/2000 is the same. OCFS for Windows does support a shared Oracle Home.

OCFS2 is the latest version of the Oracle Cluster File System software. While OCFS Version 1 was designed specifically for Oracle Database files, OCFS Ver 2 supports a shared ORACLE_HOME installation also.

New features of the OCFS Version 2 include:

  • Shared ORACLE_HOME.
     

  • Improved performance of metadata operations (space allocation, locking, etc).
     

  • Improved metadata caching.
     

  • Improved data caching (for files such as oracle binaries, libraries, etc).
     

  • Network based DLM is used by default.
     

  • Improved journaling / node recovery - we now use the Linux Kernel "JBD" subsystem.
     

  • Keep the same performance for Oracle data files as OCFS1.
     

  • CDSL for node specific files.
