We currently run solaris 10 using zfs/zones.
We have a global zone and several sparse root zones.
The oracle upgrade (from 10.2.0.4 to 18.104.22.168) prerequiste check is reporting the following warnings:
OS kernel parameter "tcp_smallest_anon_port" plus 3 other warnings for tcp_largest_anon_port and for the udp ports as well
This requires that we use ndd to change the values for these ports in the global zone.
These changes will affect all of the sparse root zones and not just the one we are upgrading Oracle in.
Will this pose any problems or is safe to make these port changes in the global zone.
