Organization: Fat City Network Services, San Diego, California X-ListServer: v1.0g, build 73; ListGuru (c) 1996-2003 Bruce A. Bergman Precedence: bulk Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hello everyone, I've come across an IBM whitepaper: "improving database performance with aix concurrent io". IBM have tested this with Oracle 9i R2 and claim performance comparable to using raw-volumes. Has anyone in the fatcity community ever tried this? Does Oracle do an open of the database files using the o_cio flag? Or should one mount the jfs2 filesystem using the -o cio option? Looking forward to your reactions.
