RAC打补丁的步骤
1.关闭所有实例及监听,还有oracle_home下的程序,ps -ef|grep oracle。
2.在原安装oracle软件的节点上打补丁。
It is important that you install the patch set on the same set of nodes, which had the base release installation. Choosing a different set of nodes during the patch set installation than were chosen during the base release installation will cause unwanted results in your Real Application Clusters environment, as some nodes will be upgraded to the new software versions, while others will not.
3.启动单个实例。
alter system set java_pool_size=300m scope=spfile
alter system set cluster_database=false scope=spfile;
shutdown immediate
4.startup migrate
@?/rdbms/admin/catpatch.sql
@?/rdbms/admin/utlrp.sql
alter system set java_pool_size=0 scope=spfile;
alter system set cluster_database=true scope=spfile;
shutdown immediate
5.startup
