Oracle服務器修改IP后

　　

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，於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 start

 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
