If you are using the command prompt version of Sqlplus, then you can use the cmd.exe's TITLE command for that. Here's my i.sql which I use both for identifying where I'm logged on before doing any changes to database, plus it is called through login.sql. The window title change happens on the last line: ---------------------- cut here ---------------------- define mysid=unknown col username for a12 col i_sid head SID for a6 new_value mysid col serial# for 999999 col opid for 999999 col spid for 999999 col host_name for a25 col i_ver head VER for a10 col i_startup_day head STARTED for a8 select s.username, i.instance_name, i.host_name, (select substr(banner, instr(banner, 'ease ')+5,10) from v$version where rownum =1) i_ver, to_char(startup_time, 'YYYYMMDD') i_startup_day, to_char(s.sid) i_sid, s.serial#, p.spid, p.pid opid, s.saddr, p.addr PADDR from v$session s, v$instance i, v$process p where s.paddr = p.addr and sid = (select sid from v$mystat where rownum = 1); host title &_user@&_connect_identifier [&mysid] ---------------------- cut here ---------------------- And the output is: SQL*Plus: Release 10.2.0.3.0 - Production on Sun Sep 9 12:16:15 2007 Copyright (c) 1982, 2006, Oracle.
