ORA-01586: database must be mounted EXCLUSIVE and not open for this operation

Hi,

I got ” ORA-01586: database must be mounted EXCLUSIVE and not open for this operation ” error during drop database.

 

Details of error are as follows. When I try to drop database in mount mode, i got the following error.

SQL> startup mount restrict;
ORACLE instance started.
Database mounted.


SQL> drop database;
drop database
*
ERROR at line 1:
ORA-01586: database must be mounted EXCLUSIVE and not open for this operation

 

 

 

This error is related with the Cluster Database ( Oracle RAC ).

To solve this error you should change the cluster_database to false from true as follows.

 

SQL> alter system set cluster_database=FALSE scope=spfile;

 

Then shutdown database and mount it in restricted mode again as follows.

SQL> shutdown immediate;


SQL>startup mount restrict;
ORACLE instance started.

Database mounted.

 

Now you can drop database as follows.

SQL>Drop Database;

Database dropped.
