RAC环境删除数据库

OS:Centos 7
DB:18.3.0.0

 

1.在其中一个节点上执行如下命令(当前数据库是在open模式,数据库在关闭模式下也可以删除)
[oracle@rac01 ~]$ dbca -silent -deleteDatabase -sourceDB slnngk
Enter SYS user password:

[WARNING] [DBT-19202] The Database Configuration Assistant will delete the Oracle instances and datafiles for your database. All information in the database will be destroyed.

Look at the log file "/u01/oracle/app/cfgtoollogs/dbca/slnngk/slnngk.log" for further details.

2.查看资源情况
[grid@rac01 ~]$ crsctl stat resource -t
命令已经没有数据库资源了

3.数据文件情况
ASMCMD> ls
ARCHIVELOG/
AUTOBACKUP/
dataguardconfig/
ASMCMD> pwd
+data/slnngk

发现相应的数据文件也一起删除了
