在一臺機器配置兩個listener

問題：一臺機器同時裝兩套數據庫時（實例名o8161,o8151)，無法同時啟動兩個listener，
當啟動第二個listener時，顯示錯誤。 $ lsnrctl start LSNRCTL for IBM/AIX RISC System/6000: Version 8.1.5.0.0 - PRodUCtion on 14-SEP-00 09:25:17 (c) Copyright 1998 Oracle Corporation. All rights reserved. TNS-01106: Listener using listener name LISTENER has already been started $ oerr tns 1106
01106, 00000, "Listener using listener name %s has already been started"
// *Cause: Another listener is already listening on one of the ADDRESSes
// specified.
// *Action: Shutdown the previous listener specified by the listener name
// before starting this one. 問題產生原因：
兩個實例的LISTENER.ORA中ipC協議的KEY是相同，而一個系統中KEY必須是唯一的. 解決辦法：
修改key的值即可。修改后的文件信息：
o8161實例：（沒有修改)
