I run a small SQL block and since that involves a lot of dbms_output.put_line statements and therefore have to run the following set options, before running the block:
set serveroutput on size 1000000
set linesize 100
But I have to do this everytime I login to run the block. So,
1) Can I safely assume that these statements only affect my current Oracle session?
2) What should I do to change it for my particular ID? (I don't know if its possible too...)
