awrload导入awr数据出现两种常见错误说明

发表于 2012 年 11 月 15 日由惜分飞

ORA-06502/ORA-06512错误

因为导出来的awr数据库的编码是AL32UTF8,而现在的编码是ZHS16GBK,所以解决方法是设置NLS_LANG为合适编码

[oracle@xifenfei ~]$ env|grep NLS_LANG
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
[oracle@xifenfei ~]$ export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

这里我们可以看到,dmp文件名为31个字符，而在提示文件名的时候是30个字符，从而出现了dmp文件不存在而导致的相关错误，解决方案重命名dmp文件，名称不超过30个字符

windows中使用dd程序

发表于 2012 年 11 月 14 日由惜分飞

很多习惯了Linux和Uinx的人都困惑windows中没有dd这样的好命令,经过不懈的努力终于发现了win dd
帮助命令

E:\>dd --help
rawwrite dd for windows version 0.6beta3.
Written by John Newbigin <jn@it.swin.edu.au>
This program is covered by terms of the GPL Version 2.

dd [bs=SIZE] [count=BLOCKS] [if=FILE] [of=FILE] [seek=BLOCKS] [skip=BLOCKS] 
[--size] [--list] [--progress]
SIZE and BLOCKS may have one of the following suffix:
 k = 1024
 M = 1048576
 G = 1073741824
default block size (bs) is 512 bytes
skip specifies the starting offset of the input file (if)
seek specifies the starting offset of the output file (of)
