Tablespace management
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0
My tablespace Users is 100% Full . It contains a single datafile , users01.dbf . 
AutoExtend Yes 
Increment 1280KB 
Filesize 32767.5 MB
Maximum File Size 32767MB . 
Is it possible to alter this datafile and change to max file size unlimited ? If not , Is it better to add a datafile with maxfilesize unlimited or is it better to set a filesize limit ?
