monitoring temp tablespace with tempfile

Version 10.2.0.3 on solaris 9.

 I have a temp tablespace with tempfiles. There are three tempfiles in the tablespace with 2G in size for each tempfile.

When I check the alert.log file I am getting the following:

Mon Aug 30 13:12:43 2010
ORA-1652: unable to extend temp segment by 12800 in tablespace                 TEMP_A
Mon Aug 30 13:17:40 2010
ORA-1652: unable to extend temp segment by 12800 in tablespace                 TEMP_A

Is this saying the tempfile is too small? My current temp tablespace is about 6G. Is it efficient to add more space to temp? What is the guideline to size the temp tablespace? Thanks.

Howdy, Stranger!
