Help: Got stuck when start SQL*Net

Hi Oracle Guru,

I got stuck when my Oracle server (Oracle 7.2.3, SQL*Net 2.2, over Sparc20, Solaris 2.4) got reboot. When I start the lsnrctl, it stuck with error:

Attempted to listen on: (DESCRIPTION=(CONNECT_TIMEOUT=10)(ADDRESS=(PROTOCOL=IPC)(KEY=CS.ust.hk))) TNS-12560: TNS:protocol adapter error
 TNS-00530: Protocol adapter error
  SVR4 Error: 80: Name not unique on network

Here's part of the trace file:

....
Resolved "CONNECT_TIMEOUT_LISTENER" to: 10 Resolved "STARTUP_WAIT_TIME_LISTENER" to: 0 (DESCRIPTION=(CONNECT_TIMEOUT=10)(ADDRESS=(PROTOCOL=IPC)(KEY=CS.ust.hk))) KEY = CS.ust.hk

Trying lot of stuff I finally comment out the IPC section of the listener.ora and it works! Here is my listener:

LISTENER =
  (ADDRESS_LIST =

#        (ADDRESS=
#         (PROTOCOL=IPC)
#         (KEY= CS.ust.hk)
#        )
#       (ADDRESS=
#         (PROTOCOL=IPC)
#         (KEY= ORACLE_CS)
#        )
        (ADDRESS =
          (COMMUNITY = cs.ust.hk)
          (PROTOCOL = TCP)

Well, though it works, but it is much slower. My listener.ora works at Day 1. Any idea the reason behind? Thanks.

Wilson.
