linux上重启oracle

linux启动oracle

• 启动oracle的步骤

  Linux下启动oracle分为以下两步：
      1.1、启动lsnrctl监听。
      1.2、启动数据库实例。
  

• 启动oracle监听

  首先登陆服务器，切换到oracle用户。
  [admin@dataserver ~]$ su - oracle
  密码：
  [oracle@dataserver ~]$
  
  
  接下来，检查oracle监听器运行状态，通过lsnrctl status命令查看。
  [oracle@dataserver ~]$ lsnrctl status

  Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))
  TNS-12541: TNS:no listener
   TNS-12560: TNS:protocol adapter error
    TNS-00511: No listener
     Linux Error: 2: No such file or directory
  Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=30.85.227.24)(PORT=1521)))
  TNS-12543: TNS:destination host unreachable
   TNS-12560: TNS:protocol adapter error
    TNS-00513: Destination host unreachable
     Linux Error: 113: No route to host
  Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=30.85.227.23)(PORT=1521)))
  TNS-12541: TNS:no listener
   TNS-12560: TNS:protocol adapter error
    TNS-00511: No listener
     Linux Error: 111: Connection refused
  [oracle@dataserver ~]$ exit
  
  
  上述反馈的结果即为oracle监听没有启动，下面执行启动监听，通过命令lsnrctl start，结果如下：
  [oracle@dataserver ~]$ lsnrctl start
