Re: temp file does not exist

CREATE TABLESPACE <tbsname> TEMPORARY specifies that the tablespace can hold only Temporary Segments [as opposed to Permanent ones like Tables and Indexes].
But the tablespace, itself, is still "permanent" with a datafile [e.g. you cannot
startup the database if the datafile is missing !]

CREATE TEMPORARY TABLESPACE <tbsname> actually creates a tablespace that is "temporary" with a tempfile. The tempfile need not exist when starting up the database [as I believe it, although I haven't verified this myself].
The tempfile is treated as a temporary file by the underlying OS and disk-space allocation is determined by the OS [ie, the OS may create a sparse file which is not the actual size that you specify in the CREATE statement, and the OS automatically grows the file as required]. You manage the TempFiles with ALTER DATABASE TEMPFILE ...

Note : A TEMPORARY TABLESPACE can only be Locally-Managed. Conversely, a TABLESPACE TEMPORARY is Dictionary-Managed.
