TNS-01201: Listener cannot find executablen 错误

    最近在启动监听器的时候收到了TNS-01201: Listener cannot find executable...的错误提示。这个错误还真是一个一直没有碰到过的错误。咋一看还真不明白是怎么一回事呢。下面是错误的具体描述与解决方案。

1、故障描述 #在启动监听器时收到了TNS-01201错误，监听器无法找到可执行文件 oracle@DevDB02:~> lsnrctl start LISTENER_USBO2                        

LSNRCTL for Linux: Version 10.2.0.3.0 - Production on 06-JUN-2014 17:06:37

Copyright (c) 1991, 2006, Oracle.  All rights reserved.

Starting /home/oracle/OraHome10g/bin/tnslsnr: please wait...

TNSLSNR for Linux: Version 10.2.0.3.0 - Production System parameter file is /home/oracle/OraHome10g/network/admin/listener.ora Log messages written to /home/oracle/OraHome10g/network/log/listener_usbo2.log Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.202)(PORT=1403))) TNS-01201: Listener cannot find executable /users/oracle/OraHome10g/bin/oracle for SID USBO2

Listener failed to start. See the error message(s) above...

2、故障分析 #Meatlink上给出了关于这个问题的描述(Doc ID 22060.1) #需要检查ORACLE_HOME环境变量是否指向了一个有效位置 Error:  TNS 1201 Text:   Listener cannot find executable %s for SID %s ------------------------------------------------------------------------------- Cause:  The executable for the Oracle dedicated server process cannot be         found. Action: Check the appropriate SID_DESC in LISTENER.ORA to make sure that         the ORACLE_HOME component is pointing to a valid location.  If this component is not set, then check the value of the ORACLE_HOME  environment variable. Comment:This error is reported only on UNIX platforms.

3、故障解决 #原来监听器中配置的oracle_home不同于当前的ORACLE_HOME oracle@DevDB02:~> more $ORACLE_HOME/network/admin/listener.ora LISTENER_USBO2 =   (DESCRIPTION_LIST =     (DESCRIPTION =       (ADDRESS_LIST =         (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.202)(PORT = 1403))       )     )   )

SID_LIST_LISTENER_USBO2 =   (SID_LIST =     (SID_DESC =         (sid_name=USBO2)         (oracle_home = /users/oracle/OraHome10g)     )   )

oracle@DevDB02:~> echo $ORACLE_HOME /home/oracle/OraHome10g

#由于直接从另外一台机器复制了listener配置内容，新机器与旧机器使用了不同的ORACLE_HOME #于是收到了上面的错误提示，下面是更正后的内容，再次重启正常 oracle@DevDB02:~> grep home $ORACLE_HOME/network/admin/listener.ora         (oracle_home = /home/oracle/OraHome10g)
