Both RedHat Advanced Server 2.1 and Suse SLE Enterprise 7.0 are sertified
for use Oracle RAC 9i (9.2.0). But RedHat Advanced Server 2.1 based on
kernel for 7.2 (not 7.3). This is problem. I don't now RH did change glibc
or not in RH 7.3, because in most cases Oracle incompatible with glibc on link stage
(as a rule for sql*net and then only for rdbs)
