用Oracle启动两个监听

 Oracle服务器更换IP后,办公网络里面可以正常访问了,外地的同事,连了外网也可以访问,以为可以收工回家,突然又有同事过来说,机房的服务器ping不通新的ip了。

  换了几台机器,都ping不通,ping其他新ip一个段的服务器又正常,也可以ssh,又试了下以前的ip地址,可以ping通。

  总结起来, ping不通的服务器都是Oracle服务器在同一个网段的服务器,以前都是10段的,Oracle服务器换了ip后,外部访问的地址就不是10段了,但是同一个段的服务器,又不能去另一个路由器绕一圈回来访问192段,所有不能访问 。(猜测)

  Oracle服务器路由如下,默认访问地址为192段

  [oracle@venn01 admin]$ route        郑州妇科医院:http://jbk.39.net/yiyuanzaixian/sysdfkyy/

  Kernel IP routing table

  Destination Gateway Genmask Flags Metric Ref Use Iface192.xx.xx.0 * 255.255.255.0 U 0 0 0 eth1192.xx.xx.0 * 255.255.255.0 U 0 0 0 virbr010.xx.xx.0 * 255.255.255.0 U 0 0 0 eth0

  link-local * 255.255.0.0 U 1002 0 0 eth0

  link-local * 255.255.0.0 U 1003 0 0 eth1

  default 192.xx.xx.x 0.0.0.0 UG 0 0 0 eth1

  网卡 eth0 ip :10.xx.xx.xx

  网卡 eth1 ip :192.xx.xx.xx

  服务器的默认路由地址是192段的

  不想去配路由,因为不会

  所以解决办法就是, 给Oracle启动两个监听,分别监听服务器的两个IP地址,端口保持不变

  修改 listener.ora

  [oracle@ut25 admin]$ pwd/opt/oracle/db01/app/oracle/product/11.2.0/network/admin[oracle@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 = 10.xx.xx.xx)(PORT = 1521))

  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.xx.xx.xx)(PORT = 1521))

  )

  )

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

  重启监听:

  可见,Oracle的两个监听分别在两个IP地址:10和192 都起来了

  在办公网可以正常访问

  在机房内网也可以正常访问了。
