在AIX中不能启动Oracle监听器,如：IBM/AIXRISCSystem/6000Error:79

1、 AIX重启后，Oracle数据库监听器不能启动。2、 如：gt;lsnrctl statusConnecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(

1、 AIX重启后，，Oracle数据库监听器不能启动。

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

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为原来更改了/etc/hosts文件，数据库重启后，AIX系统的hostname和/etc/hosts中的不一致，让系统的hostname和/etc/hosts中的名字保持一致解决上面问题。Oracle的监听器listener.ora和AIX的/ect/hosts有很大的关系。
