機房有兩套網絡，一套辦公網，一套機房的內網，辦公網可以通過vpn在其他地方訪問，內網只能在公司辦公室訪問。團隊有同事去外地辦公，開發的時候需要通過客戶端直連數據庫，于是把數據庫服務器的網線換到辦公網的路由器下，修改個IP地址。
然后修改下Oracle的監聽就行了

具體如下：

1、修改Oracle監聽 listener.ora，修改IP地址

2、重啟監聽

# 1、修改Oracle監聽 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、重啟監聽 [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，監聽已經在新的IP地址上啟動了，使用客戶端連接正常，搞定
