EXP-00091和IMP-00010解决办法

在session4的4小题需要用到SH.COUNTRIES表，而手工建库时，这个SH用户没有这个表，就想着将别处的这个表拷贝过来。原来导出表的库

在session4的4小题需要用到SH.COUNTRIES表，而手工建库时，这个SH用户没有这个表，就想着将别处的这个表拷贝过来。

原来导出表的库：database Oracle_SID=TEST0221 版本： 11.2.0.4

需要导进的库：database ORACLE_SID=PROD 版本：10.2.0.1

因为字符集的问题，出现了EXP-00091的错误

因为数据库版本的问题，出现了IMP-00010的错误

00091, 00000, "Exporting questionable statistics."

// *Cause: Export was able export statistics, but the statistics may not be

// usuable. The statistics are questionable because one or more of

// the following happened during export: a row error occurred, client

// character set or NCHARSET does not match with the server, a query

// clause was specified on export, only certain partitions or

// subpartitions were exported, or a fatal error occurred while

// processing a table.

// *Action: To export non-questionable statistics, change the client character

// set or NCHARSET to match the server, export with no query clause,

// export complete tables. If desired, import parameters can be

// supplied so that only non-questionable statistics will be imported,

// and all questionable statistics will be recalculated.

头部验证失败是由于版本号不同所致，经试验可以通过如下方法进行修改：

可以看到头部信息 －－TEXPORT:V11.01.00，即为源数据库的版本号，将其修改为目的数据库的版本号，如本机为10.02.01，再次进行导入操作，，导入成功

[oracle@ocm1 ~]$vi COUNTRIES.dmp --直接使用vi修改下头部的版本号即可
