标题: ORACLE 监听配置的三种情况
1、首先解释一下而这的区别SID和SERVICE_NAME
（1）SID:一个数据库可以有多个实例，SID是用来标识这个数据库内部每个实例的名字

（2）SERVICE_NAME：是这个数据库对外宣称的名字

2、监听配置的三种情况：
（1）一个监听在一个IP一个端口上监听多个实例
listener.ora文件：
SID_LIST_ORCL =
  (SID_LIST =
(SID_DESC =
   (GLOBAL_DBNAME = ORCL)
   (SID_NAME = ORCL)
)
(SID_DESC =
   (GLOBAL_DBNAME = ZZY)
   (SID_NAME = ZZY)
)
  )
ORCL =
  (DESCRIPTION_LIST =
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1521))
)
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)

tnsnames.ora文件：
ZZY =
  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1521))
(CONNECT_DATA =
   (SERVER = DEDICATED)
   (SERVICE_NAME = ZZY)
)
  )
ORCL =
  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1521))
(CONNECT_DATA =
   (SERVER = DEDICATED)
   (SERVICE_NAME = orcl)
)

  )

（2）一个监听在一个IP不同端口上监听多个实例

listener.ora文件：
SID_LIST_ORCL =
  (SID_LIST =
(SID_DESC =
   (GLOBAL_DBNAME = ORCL)
   (SID_NAME = ORCL)
)
(SID_DESC =
   (GLOBAL_DBNAME = ZZY)
   (SID_NAME = ZZY)
)
  )
ORCL =
  (DESCRIPTION_LIST =
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1521))
)
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1522))
)
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)

  )

tnsnames.ora文件：
ZZY =
  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1522))
(CONNECT_DATA =
   (SERVER = DEDICATED)
   (SERVICE_NAME = ZZY)
)
  )
ORCL =
  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1521))
(CONNECT_DATA =
   (SERVER = DEDICATED)
   (SERVICE_NAME = orcl)
)

  )

（3）多个监听监听多个实例

listener.ora文件：
SID_LIST_ORCL =
  (SID_LIST =
(SID_DESC =
   (GLOBAL_DBNAME = ORCL)
   (SID_NAME = ORCL)
)
(SID_DESC =
   (GLOBAL_DBNAME = ZZY)
   (SID_NAME = ZZY)
)
  )
SID_LIST_LSS =
  (SID_LIST =
(SID_DESC =
   (GLOBAL_DBNAME = LSS)
   (SID_NAME = LSS)
)
）
ORCL =
  (DESCRIPTION_LIST =
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1521))
)
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
  )
LSS=
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1522))

)

tnsnames.ora文件：
ZZY =
  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1520))
(CONNECT_DATA =
   (SERVER = DEDICATED)
   (SERVICE_NAME = ZZY)
)
  )
ORCL =
  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1521))
(CONNECT_DATA =
   (SERVER = DEDICATED)
   (SERVICE_NAME = orcl)
)
  )
LSS =
  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.66.8)(PORT = 1522))
(CONNECT_DATA =
   (SERVER = DEDICATED)
   (SERVICE_NAME = LSS)
)

  )
