How can I delete the users datafile in Oracle using SQL?
Question:
Tag: oracle,ddl,tablespace
I have tried dropping the datafile by itself but I get this error.
SQL> alter tablespace USERS drop datafile '/u01/app/oracle/oradata/orcl/users01.dbf';
alter tablespace USERS drop datafile '/u01/app/oracle/oradata/orcl/users01.dbf'
*
ERROR at line 1:
ORA-03261: the tablespace USERS has only one file
I have also tried taking the tablespace offline and dropping the whole tablespace but that doesn't work either.
SQL> drop tablespace users including contents and datafiles;
drop tablespace users including contents and datafiles
*
ERROR at line 1:
ORA-12919: Can not drop the default permanent tablespace
Edit: This is for an assignment to simulate the failure of a datafile that I will be recovering. I would delete it manually but the assignment is requiring me to use SQL.
Answer:
If you only want to drop the datafile to simulate a hardware failure, than you can simply delete them from the machine.
You can know where are stored your datafile using a simple query :
select name
from V$DATAFILE;
This will give the path to all data files.
Edit : To simulate an even more cool system failure to make sure your backup scripts or whatever you are testing is properly working, you could also corrupt the data (open a file and write some random gibberish in it)
