在上一节的配置中，已经完成了对新节点rac3的crs和数据库软件的部署，本节中主要介绍如何部署rac3上的监听器，ASM实例和数据库实例！在开始之前，应当保证各节点的服务运行正常，具体配置参考：
| [oracle@rac2 ~]$ crs_stat -t -v Name Type R/RA F/FT Target State Host ---------------------------------------------------------------------- ora....SM1.asm application 0/5 0/0 ONLINE ONLINE rac1 ora....C1.lsnr application 0/5 0/0 ONLINE ONLINE rac1 ora.rac1.gsd application 0/5 0/0 ONLINE ONLINE rac1 ora.rac1.ons application 0/3 0/0 ONLINE ONLINE rac1 ora.rac1.vip application 0/0 0/0 ONLINE ONLINE rac1 ora....SM2.asm application 0/5 0/0 ONLINE ONLINE rac2 ora....C2.lsnr application 0/5 0/0 ONLINE ONLINE rac2 ora.rac2.gsd application 0/5 0/0 ONLINE ONLINE rac2 ora.rac2.ons application 0/3 0/0 ONLINE ONLINE rac2 ora.rac2.vip application 0/0 0/0 ONLINE ONLINE rac2 ora.rac3.gsd application 0/5 0/0 ONLINE ONLINE rac3 ora.rac3.ons application 0/3 0/0 ONLINE ONLINE rac3 ora.rac3.vip application 0/0 0/0 ONLINE ONLINE rac3 ora.racdb.db application 0/1 0/1 ONLINE ONLINE rac1 ora....b1.inst application 0/5 0/0 ONLINE ONLINE rac1 ora....b2.inst application 0/5 0/0 ONLINE ONLINE rac2 |
一：配置监听器
[oracle@rac1 ~]$ netca
| 后台日志信息如下： Oracle Net Services Configuration: Configuring Listener:LISTENER rac1... rac2... rac3... Listener configuration complete. Oracle Net Services configuration successful. The exit code is 0 |
使用crs_stat命令可以看到rac3上的监听器已经正常
| [oracle@rac1 ~]$ crs_stat -t -v Name Type R/RA F/FT Target State Host ---------------------------------------------------------------------- ora....SM1.asm application 0/5 0/0 ONLINE ONLINE rac1 ora....C1.lsnr application 0/5 0/0 ONLINE ONLINE rac1 ora.rac1.gsd application 0/5 0/0 ONLINE ONLINE rac1 ora.rac1.ons application 0/3 0/0 ONLINE ONLINE rac1 ora.rac1.vip application 0/0 0/0 ONLINE ONLINE rac1 ora....SM2.asm application 0/5 0/0 ONLINE ONLINE rac2 ora....C2.lsnr application 0/5 0/0 ONLINE ONLINE rac2 ora.rac2.gsd application 0/5 0/0 ONLINE ONLINE rac2 ora.rac2.ons application 0/3 0/0 ONLINE ONLINE rac2 ora.rac2.vip application 0/0 0/0 ONLINE ONLINE rac2 ora....C3.lsnr application 0/5 0/0 ONLINE ONLINE rac3 ora.rac3.gsd application 0/5 0/0 ONLINE ONLINE rac3 ora.rac3.ons application 0/3 0/0 ONLINE ONLINE rac3 ora.rac3.vip application 0/0 0/0 ONLINE ONLINE rac3 ora.racdb.db application 0/1 0/1 ONLINE ONLINE rac1 ora....b1.inst application 0/5 0/0 ONLINE ONLINE rac1 ora....b2.inst application 0/5 0/0 ONLINE ONLINE rac2 |
二：配置ASM实例
[oracle@rac1 ~]$ dbca
验证：
| [oracle@rac1 ~]$ crs_stat -t -v Name Type R/RA F/FT Target State Host ---------------------------------------------------------------------- ora....SM1.asm application 0/5 0/0 ONLINE ONLINE rac1 ora....C1.lsnr application 0/5 0/0 ONLINE ONLINE rac1 ora.rac1.gsd application 0/5 0/0 ONLINE ONLINE rac1 ora.rac1.ons application 0/3 0/0 ONLINE ONLINE rac1 ora.rac1.vip application 0/0 0/0 ONLINE ONLINE rac1 ora....SM2.asm application 0/5 0/0 ONLINE ONLINE rac2 ora....C2.lsnr application 0/5 0/0 ONLINE ONLINE rac2 ora.rac2.gsd application 0/5 0/0 ONLINE ONLINE rac2 ora.rac2.ons application 0/3 0/0 ONLINE ONLINE rac2 ora.rac2.vip application 0/0 0/0 ONLINE ONLINE rac2 ora....SM3.asm application 0/5 0/0 ONLINE ONLINE rac3 ora....C3.lsnr application 0/5 0/0 ONLINE ONLINE rac3 ora.rac3.gsd application 0/5 0/0 ONLINE ONLINE rac3 ora.rac3.ons application 0/3 0/0 ONLINE ONLINE rac3 ora.rac3.vip application 0/0 0/0 ONLINE ONLINE rac3 ora.racdb.db application 0/1 0/1 ONLINE ONLINE rac3 ora....b1.inst application 0/5 0/0 ONLINE ONLINE rac1 ora....b2.inst application 0/5 0/0 ONLINE ONLINE rac2[oracle@rac3 ~]$ export ORACLE_SID=+ASM3 [oracle@rac3 ~]$ asmcmd ASMCMD> ls DATA/ FRA/ ASMCMD> cd data ASMCMD> ls RACDB/ ASMCMD> cd racdb ASMCMD> ls CONTROLFILE/ DATAFILE/ ONLINELOG/ |
二：配置数据库实例
[oracle@rac1 ~]$ dbca
验证：
| [oracle@rac1 ~]$ crs_stat -t -v Name Type R/RA F/FT Target State Host ---------------------------------------------------------------------- ora....SM1.asm application 0/5 0/0 ONLINE ONLINE rac1 ora....C1.lsnr application 0/5 0/0 ONLINE ONLINE rac1 ora.rac1.gsd application 0/5 0/0 ONLINE ONLINE rac1 ora.rac1.ons application 0/3 0/0 ONLINE ONLINE rac1 ora.rac1.vip application 0/0 0/0 ONLINE ONLINE rac1 ora....SM2.asm application 0/5 0/0 ONLINE ONLINE rac2 ora....C2.lsnr application 0/5 0/0 ONLINE ONLINE rac2 ora.rac2.gsd application 0/5 0/0 ONLINE ONLINE rac2 ora.rac2.ons application 0/3 0/0 ONLINE ONLINE rac2 ora.rac2.vip application 0/0 0/0 ONLINE ONLINE rac2 ora....SM3.asm application 0/5 0/0 ONLINE ONLINE rac3 ora....C3.lsnr application 0/5 0/0 ONLINE ONLINE rac3 ora.rac3.gsd application 0/5 0/0 ONLINE ONLINE rac3 ora.rac3.ons application 0/3 0/0 ONLINE ONLINE rac3 ora.rac3.vip application 0/0 0/0 ONLINE ONLINE rac3 ora.racdb.db application 0/1 0/1 ONLINE ONLINE rac3 ora....b1.inst application 0/5 0/0 ONLINE ONLINE rac1 ora....b2.inst application 0/5 0/0 ONLINE ONLINE rac2 ora....b3.inst application 0/5 0/0 ONLINE ONLINE rac3 [oracle@rac1 ~]$ sqlplus /nolog SQL*Plus: Release 10.2.0.1.0 - Production on Wed Nov 30 19:34:26 2011 Copyright (c) 1982, 2005, Oracle. All rights reserved. SQL> conn /as sysdba Connected. SQL> select inst_id,instance_name,status from gv$instance; INST_ID INSTANCE_NAME STATUS ---------- -------------------- ------ 1 racdb1 OPEN 3 racdb3 OPEN 2 racdb2 OPEN |
总结：rac节点的添加删除总体上讲，难度不大，但是部署非常繁琐，10.2.0.1的数据库版本在配置新节点的crs和数据库软件的时候存在小bug，后续版本有没有这个问题未知……
