Recreating TEMP

Hi all ,
I have 2 TEMPORARY tablespaces which I want to drop and recreate with better storage options. My worries:
1)If I connect as sysdba, what TEMP talespace will sysdba's session be using given that a select from dba_users shows SYS & SYSTEM users having TEMP as their TEMPORARY tablespace. Won't the dropping of TEMP leave sysdba in suspense over which TEMP to use ? Or as long as no sort operations, no need for TEMP ?
Waiting for your comments before:
SQL>DROP tablespace TEMP

   2>INCLUDING CONTENTS
   3>and DATAFILES;

SQL> CREATE TEMPORARY TABLESPACE TEMP
> ................................;
