Oracle服务器修改IP后

　　

机房有两套网络，一套办公网，一套机房的内网，办公网可以通过vpn在其他地方访问，内网只能在公司办公室访问。团队有同事去外地办公，开发的时候需要通过客户端直连数据库，于是把数据库服务器的网线换到办公网的路由器下，修改个IP地址。
然后修改下Oracle的监听就行了

具体如下：

1、修改Oracle监听 listener.ora，修改IP地址

2、重启监听

# 1、修改Oracle监听 listener.ora
cd $ORACLE_HOME/network/admin/
[oracle@venn01 admin]$ pwd
/opt/oracle/db01/app/oracle/product/11.2.0/network/admin
[root@venn01 admin]# more listener.ora
# listener.ora Network Configuration File: /opt/oracle/db01/app/oracle/product/11.2.0/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /opt/oracle/db01/app/oracle/product/11.2.0)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.101)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /opt/oracle/db01/app/oracle

# restart oracle listener
# 2、重启监听
[oracle@venn01 ~]$ lsnrctl start

 可以看到，监听已经在新的IP地址上启动了，使用客户端连接正常，搞定
