oracle 10G RAC之VIP探讨(1)

  【IT168 服务器学院】1.测试环境

  two nodes RAC in vmware gsx2.1 for linux
  系统环境:Redhat Enterprise Linux AD 3 Update 2(kernel:2.4.21-15.EL)
  oracle环境: oracle 10.0.2 for linux x86
  网络环境:
  node public network private network VIP network

  node1 192.168.0.61 192.168.1.1 192.168.0.60

  node2 192.168.0.62 192.168.1.2 192.168.0.59

  节点 hosts files
  #cat /etc/hosts

  # Do not remove the following line, or various programs
  # that require network functionality will fail.
  127.0.0.1 localhost.localdomain localhost
  192.168.0.61 DB1PUB DB1PUB.SHIMU.COM.CN
  192.168.0.62 DB2PUB DB2PUB.SHIMU.COM.CN
  192.168.0.60 VIPDB.SHIMU.COM.CN
  192.168.0.59 VIPDB2.SHIMU.COM.CN
  192.168.1.1 DB1
  192.168.1.2 DB2

  instance: RAC1 ,RAC2
  service : RAC.SHIMU.COM.CN

  2.网络环境研究

  正常的两nodes的10G RAC网络环境应该是有6个ip(除了loopback),每个机器包括3个ip其正常的运行环境的网络环境
  通过ifconfig 得到网络环境
  node1:
  [root@DB1PUB root]# ifconfig -a

  2.listener研究
  10G的listener也做了改动参见如下:
  # listener.ora.db2pub Network Configuration File: /oracle/10g2/network/admin/listener.ora.db2pub
  # Generated by Oracle configuration tools.

  LISTENER_DB1PUB =
  (DESCRIPTION_LIST =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.61)(PORT = 1521))
  )
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.60)(PORT = 1521))
  )
  )
  )

  SID_LIST_LISTENER_DB2PUB =
  (SID_LIST =
  (SID_DESC =
  (SID_NAME = PLSExtProc)
  (ORACLE_HOME = /oracle/10g2)
  (PROGRAM = extproc)
  )
  )

  此时oracle系统的监听器是同时监听public,和vip地址一下是listener的node1的监听信息

  [oracle@DB1PUB oracle]$ lsnrctl statu DB1PUB

  其中多了监听8080和2100起具体作用还值得研究
