Port Requirements
Oracle 11gR2 RAC requires HP-UX kernel TCP/IP ephemeral port range to be set in the range
9000- 65500.
Use NDD to ensure that the HP-UX kernel TCP/IP ephemeral port range parameters are set to 9000-
65500 on each node.
Example:
You can use the following command to check the existing TCP/IP port range.
/usr/bin/ndd /dev/tcp tcp_smallest_anon_port tcp_largest_anon_port
/usr/bin/ndd /dev/udp udp_smallest_anon_port udp_largest_anon_port
Then, if required edit the file /etc/rc.config.d/nddconf and add entries to update the UDP
and TCP ephemeral port range to 9000- 65500.
TRANSPORT_NAME[0]=tcp
NDD_NAME[0]=tcp_largest_anon_port
NDD_VALUE[0]=65500
TRANSPORT_NAME[1]=tcp
NDD_NAME[1]=tcp_smallest_anon_port
NDD_VALUE[1]=9000
TRANSPORT_NAME[2]=udp
NDD_NAME[2]=udp_largest_anon_port
NDD_VALUE[2]=65500
TRANSPORT_NAME[3]=udp
NDD_NAME[3]=udp_smallest_anon_port
NDD_VALUE[3]=9000
