I beg to disagree David. I just verified that I am in fact running 2 standby 9.2.0.8 DBs on my RHEL 5.1 box along with a couple of 11.1.0.6 DBs. It works just fine. Now whether or not it is a blessed i.e. fully supported configuration - couldn't say. FYI, this is RHEL x86 32 bit, not 64. -- Jay Weinshenker jweinshe@xxxxxxxxxxxxxx -- //www.freelists.org/webpage/oracle-l
