使用Oracle提供的字符扫描工具csscan的步骤：
1.首先以sys用户身份创建相应数据字典对象:
$sqlplus /nolog
SQL>conn / as sysdba
SQL>@@?/rdbms/admin/csminst.sql
SQL>exit |
2.执行csscan符集扫描工具：
详细的帮助说明可以执行csscan help=y来查看。
$csscan SYSTEM/Password FULL=y TOCHAR=utf8 ARRAY=1024000 PROCESS=3 |
3.检查扫描后的出错信息。
$ls -al |grep scan
$cat scan.err|more |
详细的执行记录：

FROMNCHAR current national character set name
ARRAY 1024000 yes size of array fetch buffer
PROCESS 1 yes number of concurrent scan process
MAXBLOCKS split table if block size exceed MAXBLOCKS
CAPTURE N capture convertible data
SUPPRESS maximum number of exceptions logged for each table
