如何实现Oracle的监听（listener）多个IP地址

来源：互联网发布：grub命令启动windows 编辑：程序博客网时间：2024/06/06 20:17

在实际工作中，一个oracle服务经常需要给多个IP提供监听和服务工作，下面我们来介绍如何给Oracle增加listen的IP地址，即使oracle监听服务增加一个ip地址；

1）listener.ora中手动增加个地址，然后重新启动listener服务即可；

b）使用oracle管理工具NetManager来实现，如下所示：

listener.ora 的具体例子

# listener.ora Network Configuration File: D:\oracle\server\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = d:\oracle\server\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:d:\oracle\server\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = d:\oracle\server\product\11.2.0\dbhome_1)
(SID_NAME = orcl)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.20)(PORT = 1521))
)
)

ADR_BASE_LISTENER = d:\oracle\server
