数据库启动各阶段监听器状态变化详解（Oracle/MySQL等）

首先listener.ora配置如下：

SID_LIST_LISTENER =

    (SID_LIST =

      (SID_DESC =

        (SID_NAME = PLSExtProc)

        (ORACLE_HOME = /orainst/product/10/db_1)

        (PROGRAM = extproc)

      )

      (SID_DESC =

        (GLOBAL_DBNAME = enovia)

        (ORACLE_HOME = /orainst/product/10/db_1)

        (SID_NAME = enovia)

      )

    )

LISTENER =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.2.37)(PORT = 1521))

    )
