Ashoke The problem with long SID names or special characters is that the SID is used in a lot of circumstances. For example, on Unix systems, you end up with other characters being concatenated with the SID and this becomes a process name (as in lgwr_ora_$ORACLE_SID). So the issue isn't entirely within Oracle's control. The recommendation has traditionally been to keep it to 4 or 5 characters, strictly alphanumeric. The danger is that you will get the instance created just fine and then somewhere later encounter a situation where your special SID exceeds something else's limits. Hitting issues like this is why the more experienced DBAs tend also to be fairly conservative. Usually you have to solve enough problems without creating your own.

Can I have special character in SID/Database name? e.g. Is a SID name 'emp_prod' is allowed? 2. What is the maximum size of a SID/Database name in Unix? 3. What is the maximum size of a SID/Database name in Windows? 4. Is there any other restrictions?
