http://files.meetup.com/1729503/1729503/All_about_ASM.pdf
When a tablespace is getting filled up, action need to be taken (Preference-wise)
1. Resize the datafile.
2. If AUTOEXTEND ON,then resize the maxsize of the datafile.
3. Add a new datafile to the tablespace.
Note:-
Check the availability of the free space on the disk at OS level.
