I installed Oracle 10g R2 RAC on RHEL4(U4), the RAC nodes work fine, but after I restart all nodes, I found the listener was listening on 0.0.0.0(1521), instead of the vip and local IP.

tcp 0 0 0.0.0.0:1521 0.0.0.0:* LISTEN 17043/tnslsnr

Before reboot, it is like: (2.147 is the vip)
tcp 0 0 172.16.2.145:1521 0.0.0.0:* LISTEN 18449/tnslsnr
tcp 0 0 172.16.2.147:1521 0.0.0.0:* LISTEN 18449/tnslsnr

My listener parameter file is like:
LISTENER_RH4RAC01 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rh4rac01-vip.mydomain.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.2.145)(PORT = 1521))
)
)

I tried restarting the listener by "lsnrctl stop" and "lsnrctl start", but nothing changed on the listner status.
What is the problem? I don't like it listening on 0.0.0.0. How can I fix?
