You can move the files, but not while the database is using them. You can perform the moves by taking the tablespace offline, moving the file and then instructing Oracle of the new location. Use the following steps:
- ALTER TABLESPACE tools OFFLINE;
- Use OS commands to move tools01.dbf to its new location.
- ALTER DATABASE RENAME FILE '/old_directory/tools01.dbf' TO '/new_directory/tools01.dbf';
- ALTER TABLESPACE tools ONLINE;
Repeat for the other tablespaces.
