Re: oracle clusterware: stonith

Well

I think Oracle Clusterware does something like STONITH, the node evicts the other node/s, stonith is an algorithm and what Oracle Clusterware does is something similar, when a node is ill the healthy node evicts it (shoots the other node?)

In Linux we have hang check timer and in UNIX oprocd to fence if CRS is not able to.

Has anyone see a RAC data corruption due to Clusterware unable to shoot itself?

Not expert here neither ;-)

Thanks
