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
导出dmp文件信息：
[oracle@node2 ~]$ exp sh/sh@test0221 tables=COUNTRIES rows=y file=COUNTRIES.dmp

[oracle@node2 ~]$ oerr exp 00091 (这个貌似是查看 00091报错 的详解)(oerr 溢出错误)
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.
