[Linux-cluster] 9i RAC GFS Certification?

Any idea as to how long "near term" is?

Itanium support thwarts us at every turn (and we have 20 of them!), 10g with
GFS 6.1 on RHEL4-ia64 would answer all of my prayers.

Your last statement is incorrect.  Red Hat GFS folks are working with
Oracle to certify 10gR2 on GFS 6.1 on RHEL 4 in the near term; however,
GULM is the only supported lock manager for this certification.  They
require 3 external nodes to the RAC cluster (none of the RAC nodes can
be a standy lock node, for example).

Red Hat told me this was at the insistence of Oracle.  :(
