We are just now starting the process of looking at RAC. So far, I am pretty much overwhelmed by all of the different acronyms, products, terms, etc. I am lost..... For those of you who are using RAC, how many are using the Oracle Cluster File System software instead of vendor supplied software? HP is coming in tomorrow to pitch their HP Serviceguard CFS software. Does anyone use this for their RAC? Thanks, Tom -- //www.freelists.org/webpage/oracle-l
