Hello, I'm fairly new to this list. Could someone point me to the document which states Oracle and Red Hat have certified 9i RAC on GFS? I'm looking for a certification matrix; for example, I've heard only GLM, not DLM, is certified as the locking manager. Is this correct? I've read the GFS 6.1 docs and I'm starting the RHCS guide. Any other documents would be greatly appreciated. I've already seen the thread about 2-node to 3+-node migration hell which requires a cluster down time (yuck!). Thanks for any tips as I try to certify 9i RAC on GFS for use in our IT dept. /Brian/ -- Brian Long | | | IT Data Center Systems | .|||. .|||. Cisco Linux Developer | ..:|||||||:...:|||||||:..
