RAC 升级实录

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.  All Rights Reserved.
