Dear list, I had the chance to make a quick and drity test of ACFS with Oracle Enterprise Linux in a VMware ESX environment. In my opinion, the setup is painless, but I asked myself why I can't configure NORMAL redundancy in MY way (with only two disks) during runInstaller, but okay. Other question that did arise: Why is ACFS slower by half than native ASM disk access? Is it my setup, is it VMware, is it better on hardware? I don't talk about the absolute numbers, but the rlation is sad I'd daresay. This link only covers the performance test and a bit reconfiguration, not the install procedure which is easily to be found on the net. http://www.usn-it.de/index.php/2009/09/15/oracle-11gr2-asm-acfs-a-first-benchmark-poorly/ Your personal opinion is greatly treasuered Martin Klier -- Usn's IT Blog for Linux, Oracle, Asterisk http://www.usn-it.de -- //www.freelists.org/webpage/oracle-l
