缺省情况下,使用RMAN备份与恢复界面仅仅显示的是日期,而没有具体的时间。有时候需要查看具体的时间,如查看当天多个Incarnatio

缺省情况下,使用RMAN备份与恢复界面仅仅显示的是日期,,而没有具体的时间。有时候需要查看具体的时间,如查看当天多个Incarnation的情形。对于这个问题,主要是设定环境变量参数NLS_DATE_FORMAT即可,如下文所描述。
 
1、RMAN日期及时间的缺省格式
        robin@SZDB:~> rman target /

        Recovery Manager: Release 10.2.0.3.0 - Production on Sat Jun 1 13:54:49 2013

        Copyright (c) 1982, 2005, Oracle.  All rights reserved.

        connected to target database: GOBO1 (DBID=733951103)

        RMAN> list incarnation;

        using target database control file instead of recovery catalog

        List of Database Incarnations
        DB Key  Inc Key DB Name  DB ID            STATUS  Reset SCN  Reset Time
        ------- ------- -------- ---------------- --- ---------- ----------
        1      1      GOBO1    733951103        PARENT  1          18-FEB-09
        2      2      GOBO1    733951103        PARENT  79915248  20-SEP-12
        3      3      GOBO1    733951103        PARENT  80298787  31-MAY-13
        4      4      GOBO1    733951103        CURRENT 80307144  31-MAY-13

        RMAN> exit

        Recovery Manager complete. 

2、修改环境变量对RMAN日期及时间格式进行自定义
        robin@SZDB:~> export NLS_DATE_FORMAT='yyyymmdd hh24:mi:ss';
        robin@SZDB:~> rman target /

        Recovery Manager: Release 10.2.0.3.0 - Production on Sat Jun 1 13:55:30 2013

        Copyright (c) 1982, 2005, Oracle.  All rights reserved.

        connected to target database: GOBO1 (DBID=733951103)

        RMAN> list incarnation;

        using target database control file instead of recovery catalog

        List of Database Incarnations
        DB Key  Inc Key DB Name  DB ID            STATUS  Reset SCN  Reset Time
        ------- ------- -------- ---------------- --- ---------- ----------
        1      1      GOBO1    733951103        PARENT  1          20090218 16:43:43
        2      2      GOBO1    733951103        PARENT  79915248  20120920 15:00:44
        3      3      GOBO1    733951103        PARENT  80298787  20130531 21:03:41
        4      4      GOBO1    733951103        CURRENT 80307144  20130531 22:28:05

        --Author : 

3、永久修改RMAN日期及时间格式
        最佳的办法是将该参书直接添加到.bash_profile
        robin@SZDB:~> echo "export NLS_DATE_FORMAT='yyyymmdd hh24:mi:ss'" >> ~/.bash_profile
