Zhu, Have you checked your alert log? This what you
should see in your alert log.

This on 9204 not 9205

cluster interconnect IPC version:
        VERITAS IPC 3.5MP1s+RP3a 10:36:03 Jun 24 2003
IPC Vendor 86 proto 76 Version 1.0

When I do a oradebug this what I see

VCSIPC DCTX
===================================================
VCSIPC DCTX
        VERITAS IPC 3.5MP1s+RP3a 10:36:03 Jun 24 2003
VCSIPC DCTX[ ctx.g 0x1036652a0.0x1036652a0, at 0, lif
0xffffffff7f155f50, lptyp
ANY , iocr 0, sverr 0[]  

Now as an experiment I am using Oracle's udp library
instead of the Veritas library and you will get
different results.

here is the oradebug output from using the udp
library.

SKGXPCTX: 0x368d308 ctx
admno 0x1eae5851 admport:
SSKGXPT 0x36916d8 flags         info for network 0
        socket no 0     IP 0.0.0.0      UDP 0
        sflags SSKGXPT_DOWN
        info for network 1
        socket no 9     IP 141.144.9.245        UDP
32903
        sflags SSKGXPT_UP      

The IP address listed above is my public address  and
I would expect this when using the UDP library.       
                  

This is from the alert log.

cluster interconnect IPC version:Oracle UDP/IP
IPC Vendor 1 proto 2 Version 1.0

My guess is you are using the wrong libraries.

Make sure you are using the libskgxp9.so libraries
provieded by Veritas and not the libskgxpu.so
libraries provide by Oracle. 

This is what my box looks like using Oracle's UDP
libraries on Veritas.
