Comments on: Oracle Clusterware and Fencing…Again? http://kevinclosson.wordpress.com/2007/08/17/oracle-clusterware-and-fencingagain/ Oracle-related Platform, Storage and Clustering Topics (with the occasional rant) Mon, 13 Oct 2008 15:38:29 +0000 http://wordpress.org/?v=MU hourly 1 By: Pedro Alvarez http://kevinclosson.wordpress.com/2007/08/17/oracle-clusterware-and-fencingagain/#comment-22477 Pedro Alvarez Sat, 18 Aug 2007 17:49:12 +0000 http://kevinclosson.wordpress.com/2007/08/17/oracle-clusterware-and-fencingagain/#comment-22477 Kevin, It was me who posted that. My manager wanted me to dig me out some information about the oracle clusterware. Our shop got 80 percent of unstructured data. We wanted to have a cluster file system and cluster apps (the way done on VCS), not to deal with raw disks or ASM. Therefore, we wanted to know how fencing is done in the oracle clusterware. And the oracle sales guy was not even responding at all. Given you blogged many times about fencing, I thought of posting Oracle presentation--esp about stonith. I would not have posted it on oracle-l, if they had a decent documentation Thanks for your blog, again. Kevin,

So CRS is perfect for RAC so far, may be the kernel/user mode clusterware flaws applies for those who use CRS for other purposes.... Who knows ;-) Thanks -- LiShan Cheng I think we all noted Kirk said this:

As I mentioned to Kirk, I don't think there are very many concise descriptions about Oracle Clusterware's fencing mechanisms and the challenges surrounding fencing. I also wanted to point out that the webcast you referenced is one that was for the Oracle RAC SIG (http://www.oracleracsig.org/) and there are many more recorded webcasts there available for on-demand playback. Membership is free--just sign up on the site. Thanks for the high-quality, informative posting, as usual! Dan Norris RAC SIG Events Chair Thanks for rehashing and summarizing this topic, Kevin.
