在AIX中不能啟動Oracle監聽器,如：IBM/AIX RISC System/6000 Error: 79

1、  AIX重啟後，資料庫監聽器不能啟動。

2、  如：

>lsnrctl status

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=ip)(PORT=1521)))

TNS-12541: TNS:no listener

TNS-12560: TNSrotocol adapter error

  TNS-00511: No listener

   IBM/AIX RISC System/6000 Error: 79: Connection refused

 

>lsnrctl start

3、  資料庫不能啟動

$ sqlplus "/as sysdba"

ORA-01078: failure in processing system parameters

LRM-00109: could not open parameter file '/usr/oracle/oms/102_64/dbs/initTEST.ora

 

原因：上面的原因主要是因為原來更改了/etc/hosts檔案，資料庫重啟後，AIX系統的hostname 和 /etc/hosts中的不一致，讓系統的hostname 和 /etc/hosts 中的名字保持一致解決上面問題。Oracle的監聽器listener.ora和AIX的/ect/hosts有很大的關係。
