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 startLSNRCTL for Linux: Version 11.2.0.1.0 - Production on 11-SEP-2018 13:11:13Copyright (c) 1991, 2009, Oracle.

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
