当管理的数据库比较多的时候,在sqlplus里切换就是一件麻烦的事。 要非常小心,以防出错。 可以修改sqlplus 的提示符:SQL> ,把这个改成我们用户和实例名,这样就不容易出错。
先看一下Oracle 自定义的参数:
SQL> define
DEFINE _DATE = "11-MAY-11" (CHAR)
DEFINE _CONNECT_IDENTIFIER = "dave1" (CHAR)
DEFINE _USER = "SYS" (CHAR)
DEFINE _PRIVILEGE = "AS SYSDBA" (CHAR)
DEFINE _SQLPLUS_RELEASE = "1002000100" (CHAR)
DEFINE _EDITOR = "ed" (CHAR)
DEFINE _O_VERSION = "Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, Real Application Clusters, OLAP and Data Mining options" (CHAR)
DEFINE _O_RELEASE = "1002000100" (CHAR)
我们可以使用这些定义的参数来设定相关信息,也可以使sql 来拼接显示的信息。 如:
SQL> set sqlprompt "_USER@ _CONNECT_IDENTIFIER >"
SYS@ dave1 >
但是这个方式在sqlplus 关闭之后就没有了。 要想永久的保存,就需要修改配置文件glogin.sql,sqlplus 在启动时,会读取该文件。 该文件位置:
$ORACLE_HOME/sqlplus/admin/glogin.sql
方法一:
在$ORACLE_HOME/sqlplus/admin/glogin.sql 文件里添加如下参数:
set sqlprompt "_USER@ _CONNECT_IDENTIFIER >"
然后打开sqlplus:
[oracle@rac1 admin]$ sqlplus / as sysdba;
SQL*Plus: Release 10.2.0.1.0 - Production on Wed May 11 18:46:50 2011

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, Real Application Clusters, OLAP and Data Mining options
SYS@ dave1>
方法二: 使用sql 语句拼接
在$ORACLE_HOME/sqlplus/admin/glogin.sql 文件里添加如下参数:
set time on
set termout off -- 如果不加这句,每次都会显示下面查询的select 结果集
column propmt_q new_value propmt_q
select upper(user)||'@'|| instance_name||'('||host_name||')' as propmt_q from v$instance;
set sqlprompt '&propmt_q> '
在打开sqlplus,效果如下:
[oracle@rac1 admin]$ sqlplus / as sysdba;
SQL*Plus: Release 10.2.0.1.0 - Production on Wed May 11 18:50:27 2011
Copyright (c) 1982, 2005, Oracle. All rights reserved.

With the Partitioning, Real Application Clusters, OLAP and Data Mining options
18:50:27 SYS@dave1(rac1)>select sysdate from dual;
SYSDATE
---------
11-MAY-11
18:51:27 SYS@dave1(rac1)>
把时间去掉:
set termout off -- 如果不加这句,每次都会显示下面查询的select 结果集
column propmt_q new_value propmt_q
select upper(user)||'@'|| instance_name||'('||host_name||')' as propmt_q from v$instance;
set sqlprompt '&propmt_q> '
[oracle@rac1 admin]$ sqlplus / as sysdba;
SQL*Plus: Release 10.2.0.1.0 - Production on Wed May 11 18:55:06 2011
