Oracle11g RAC 删除控制文件
注：本测试是在【Oracle11g RAC 增加控制文件（一）】这个基础上完成的。
1：一致性关闭数据库
|
1 2 |
[grid@rac1 ~]$ srvctl stop database -d racdb [grid@rac1 ~]$ |
2：删除要删除的控制文件

ASMCMD> ls CONTROLFILE/ DATAFILE/ ONLINELOG/ PARAMETERFILE/ TEMPFILE/ spfileRACDB.ora ASMCMD> cd .. ASMCMD> ls RACDB/ ASMCMD> //我们可以看到，当我们把cp创建的那两个文件删除后，自动创建的ASM目录由于已空，也一并自动删除了 |
3：1节点修改参数并启动数据库
