Q

Can I add multiple datafiles and make use of all the temporary datafiles at the same time?

An Oracle user asks: Can I add multiple datafiles and make use of all the temporary datafiles at the same time?

I have a 2GB temporary datafile. Can I add multiple datafiles and make use of all the temporary datafiles at the same time? I am using Oracle 9i.
If you add another file to your TEMP tablespace, Oracle will use it. Oracle employs a round-robin allocation method when more than one file belongs to the tablespace. Oracle will allocate one extent in the first file. The second extent will be allocated in the second file, and so on. Once all files have an extent allocated in it, Oracle will go back to the first file for the next extent. It does not matter if the extent is for a temporary segment or a permanent one.
