Oracle 10g RAC修改数据库名与实例名

发表回复

生产数据库系统在某些情况下[数据库名与业务系统名匹配]，可能需要修改数据库和实例名，该篇将详细演示，如何修改RAC数据库及实例名。
###原数据库及实例名
db_name: test
instance_name1: tets1
instance_name2: test2
###修改后数据库及实例名
db_name: k13test
instance_name1: k13tets1
instance_name2: k13test2

---查看原集群数据库和实例名运行状态

Oracle 10g RAC修改数据库实例与主机对应关系

发表回复

RAC中使用dbca在创建集群数据库时，由于未在主节点[主机号小的节点]上启动图形界面创建数据库，导致最终创建好的集群数据库实例号与主机名号之间关系不对应，例如这里的实验环境如下：
instance_name etltest1对应主机名k1rac4
instance_name etltest2对应主机名k1rac2
下面用实验演示，如何将数据库实例号与主机号的对应关系改为如下：
instance_name etltest1对应主机名k1rac2
instance_name etltest2对应主机名k1rac4
