How to add new storage for datafiles?

The location where my datafiles are stored is almost full. How to add new storage for my datafile?

We have Oracle running on Unix. The location where my datafiles are stored is almost full. How to add new storage for my datafile?
Your system administrator will have to mount a new disk volume for your use. On that mount point, your SysAdmin will need to let the 'oracle' user own a directory. That directory should be owned by the 'dba' group as well. Once that is set up, you can add a new datafile to any tablespace in your database with a command similar to the following:
ALTER TABLESPACE ts_name 
ADD DATAFILE '/new_volume/sid/ts_nameXX.dbf' SIZE ???M;
When you add the datafile, make sure you specify the new disk volume your SysAdmin has set up for you.
