修改sqlplus提示符

如图所示 ：

修改 提示符为 username(sid_serial#)@instance_name ，这样其实很方便的

以下是步骤

在11g中glogin.sql 文件是不存在的，取而代之的是 login.sql 直接编辑该文件就可

vi $ORACLE_HOME/sqlplus/bin/login.sql

set termout off
define loginname=idle
column global_name new_value loginname
#select  USER||'@'||substr(global_name,1,decode(dot,0,length(global_name),dot-1))  global_name  from (select global_name,  instr(global_name,'.') dot from global_name);
select distinct sess.username||'('||sess.sid||'_'||sess.SERIAL#||')@'||inst.instance_name global_name from v$session sess,v$mystat stat ,v$instance inst where stat.sid=sess.sid;

set sqlprompt '&loginname> '
set termout on
define_editor=vi
set linesize 200
set pagesize 100
#set time on
#set timing on

然后使用命令登录就能看见效果了

[oracle@Oracle11g bin]$ sqlplus "/as sysdba"
