本节中将演示升级rac的步骤，将rac的版本从10.2.0.1升级到10.2.0.5，对于生产环境而言，升级前需要先对数据库和ocr，表决盘等进行备份!
一：上传升级包到节点1并解压,可以在support.oracle.com上下载到该软件包
[oracle@rac1 patch]$ unzip p8202632_10205_Linux-x86-64.zip [oracle@rac1 patch]$ ls Disk1 p8202632_10205_Linux-x86-64.zip README.htm二：关闭所有的rac节点，不推荐使用crs_stop -all命令关闭，容易出现unknown现象
| [oracle@rac1 ~]$ crs_stat -t Name Type Target State Host ------------------------------------------------------------ ora....SM1.asm application ONLINE ONLINE rac1 ora....C1.lsnr application ONLINE ONLINE rac1 ora.rac1.gsd application ONLINE ONLINE rac1 ora.rac1.ons application ONLINE ONLINE rac1 ora.rac1.vip application ONLINE ONLINE rac1 ora....SM2.asm application ONLINE ONLINE rac2 ora....C2.lsnr application ONLINE ONLINE rac2 ora.rac2.gsd application ONLINE ONLINE rac2 ora.rac2.ons application ONLINE ONLINE rac2 ora.rac2.vip application ONLINE ONLINE rac2 ora.racdb.db application ONLINE ONLINE rac1 ora....b1.inst application ONLINE ONLINE rac1 ora....b2.inst application ONLINE ONLINE rac2 [oracle@rac1 ~]$ crs_stat -t Name Type Target State Host ------------------------------------------------------------ ora....SM1.asm application OFFLINE OFFLINE ora....C1.lsnr application OFFLINE OFFLINE ora.rac1.gsd application OFFLINE OFFLINE ora.rac1.ons application OFFLINE OFFLINE ora.rac1.vip application OFFLINE OFFLINE ora....SM2.asm application OFFLINE OFFLINE ora....C2.lsnr application OFFLINE OFFLINE ora.rac2.gsd application OFFLINE OFFLINE ora.rac2.ons application OFFLINE OFFLINE ora.rac2.vip application OFFLINE OFFLINE ora.racdb.db application OFFLINE OFFLINE ora....b1.inst application OFFLINE OFFLINE ora....b2.inst application OFFLINE OFFLINE |
三：升级CRS
[oracle@rac1 patch]$ cd Disk1/ [oracle@rac1 Disk1]$ ./runInstaller
| 按照提示，运行下面两个脚本 [root@rac1 ~]# /u01/app/oracle/product/10.2.0/crs_1/bin/crsctl stop crs Stopping resources. Successfully stopped CRS resources Stopping CSSD. Shutting down CSS daemon. Shutdown request successfully issued. [root@rac1 ~]# /u01/app/oracle/product/10.2.0/crs_1/install/root102.sh Creating pre-patch directory for saving pre-patch clusterware files Completed patching clusterware files to /u01/app/oracle/product/10.2.0/crs_1 Relinking some shared libraries.

四：升级数据库软件,前面升级完crs后，rac会自动启动，因而同样需要先关闭rac服务
| [oracle@rac1 ~]$ crs_stat -t -v Name Type R/RA F/FT Target State Host ---------------------------------------------------------------------- ora....SM1.asm application 0/5 0/0 OFFLINE OFFLINE ora....C1.lsnr application 0/5 0/0 OFFLINE OFFLINE ora.rac1.gsd application 0/5 0/0 OFFLINE OFFLINE ora.rac1.ons application 0/3 0/0 OFFLINE OFFLINE ora.rac1.vip application 0/0 0/0 OFFLINE OFFLINE ora....SM2.asm application 0/5 0/0 OFFLINE OFFLINE ora....C2.lsnr application 0/5 0/0 OFFLINE OFFLINE ora.rac2.gsd application 0/5 0/0 OFFLINE OFFLINE ora.rac2.ons application 0/3 0/0 OFFLINE OFFLINE ora.rac2.vip application 0/0 0/0 OFFLINE OFFLINE ora.racdb.db application 0/1 0/1 OFFLINE OFFLINE ora....b1.inst application 0/5 0/0 OFFLINE OFFLINE ora....b2.inst application 0/5 0/0 OFFLINE OFFLINE [oracle@rac1 Disk1]$ ./runInstaller |
| [root@rac1 ~]# /u01/app/oracle/product/10.2.0/db_1/root.sh Running Oracle 10g root.sh script... The following environment variables are set as: ORACLE_OWNER= oracle ORACLE_HOME= /u01/app/oracle/product/10.2.0/db_1 Enter the full pathname of the local bin directory: [/usr/local/bin]: The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y Copying dbhome to /usr/local/bin ... The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y Copying oraenv to /usr/local/bin ... The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: y Copying coraenv to /usr/local/bin ... Entries will be added to the /etc/oratab file as needed by Database Configuration Assistant when a database is created Finished running generic part of root.sh script. Now product-specific root actions will be performed. 同样需要在rac2节点上运行这个脚本！ |
五：升级数据库，需要先将数据库启动到nomount的状态，修改cluster_database初始化参数，然后重新启动实例，升级数据字典(持续时间较长)，从新编译无效的对象等
| [oracle@rac1 ~]$ crs_stat -t -v Name Type R/RA F/FT Target State Host ---------------------------------------------------------------------- ora....SM1.asm application 0/5 0/0 OFFLINE OFFLINE ora....C1.lsnr application 0/5 0/0 OFFLINE OFFLINE ora.rac1.gsd application 0/5 0/0 OFFLINE OFFLINE ora.rac1.ons application 0/3 0/0 OFFLINE OFFLINE ora.rac1.vip application 0/0 0/0 OFFLINE OFFLINE ora....SM2.asm application 0/5 0/0 OFFLINE OFFLINE ora....C2.lsnr application 0/5 0/0 OFFLINE OFFLINE ora.rac2.gsd application 0/5 0/0 OFFLINE OFFLINE ora.rac2.ons application 0/3 0/0 OFFLINE OFFLINE ora.rac2.vip application 0/0 0/0 OFFLINE OFFLINE ora.racdb.db application 0/1 0/1 OFFLINE OFFLINE ora....b1.inst application 0/5 0/0 OFFLINE OFFLINE ora....b2.inst application 0/5 0/0 OFFLINE OFFLINE [oracle@rac1 ~]$ srvctl start nodeapps -n rac1 [oracle@rac1 ~]$ srvctl start nodeapps -n rac2 [oracle@rac1 ~]$ srvctl start asm -n rac1 [oracle@rac1 ~]$ srvctl start asm -n rac2 [oracle@rac1 ~]$ srvctl start database -d racdb -o nomount [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.racdb.db application 0/1 0/1 ONLINE ONLINE rac2 ora....b1.inst application 0/5 0/0 ONLINE ONLINE rac1 ora....b2.inst application 0/5 0/0 ONLINE ONLINE rac2 [oracle@rac1 ~]$ sqlplus /nolog SQL*Plus: Release 10.2.0.5.0 - Production on Tue Dec 6 22:31:24 2011 Copyright (c) 1982, 2010, Oracle.
