I need to install the sample schema available from the Oracle website:
I am trying to run the commands as given here:
But I get this error:
ORA-01537: cannot add file 'dm.dbf' - file already part of database
Given below is the copy of the screen:
SQL> ALTER SESSION SET CONTAINER = pdborcl; Session altered. SQL> @install_olaptrain.sql Specify file system directory containing this installation program. Directory: C:\Users\Ashish\Desktop\olaptrain_install Specify a password for the OLAPTRAIN user. Password: Begin installation ... creating tablespaces declare * ERROR at line 1: ORA-01537: cannot add file 'dm.dbf' - file already part of database ORA-06512: at line 31
How can I resolve this error?
