Create second database in unix

Question

Hi, I am trying to create a second database in Oracle 10g in solaris 10. I know i need to set up the ORACLE_SID
i have 2 questions.
if i set up ORACLE_SID, am i orverwriting the current ORACLE_SID? or i am just creating another one.
another question, when i do setenv ORACLE_SID catdb
the command failed, it tells me setenv not found.
thanks.
