Oracle10g监听器的启动问题

使用的oracle安装文件：10201_database_linux_x86_64.cpio.gz

在RHEL5.0上安装完成ORACLE10g后，启动监听器时遇到了一点小麻烦。启动错误如下：

TNS-12537: TNS:connection closed
TNS-12560: TNS:protocol adapter error
TNS-00507: Connection closed
Linux Error: 29: Illegal seek

 

在监听器文件中使用localhost.localdomain作为主机标识，所以在/etc/hosts中必须有localhost（去掉domain名称的主机名）

127.0.0.1　localhost.localdomain localhost

 

这样可以启动监听器了，但仍不能使用tnsname来建立数据库连接

需要启动监听实例

有两个办法，一个是将默认实例更改为你自己的实例（本例为orcl），另一个办法是增加监听实例

1.将PLSExtProc更改为orcl，更改后的listener.ora为

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)
      #(PROGRAM = extproc)
    )

  )

 

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    )
  )

2.增加一个orcl的监听实例，更改后的listener.ora为

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
   (SID_DESC =
       (GLOBAL_DBNAME = orcl)
       (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)
       (SID_NAME = orcl)
     )

  )

 

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    )
  )
