ORA-03120: two-task conversion routine: integer overflow

今天在导入imp数据库对象的时候，碰到一个错误:"ORA-03120: two-task conversion routine: integer overflow",查询metalink此问题为9.2.0.8.0平台的一个bug。
解决办法有两个：
1.To implement the solution, it will be necessary to apply the one-off patch for Bug 5671074 to the 9.2.0.8 database.
2.客户端用9.2.0.8.0导入也可以解决这个问题。
问题重现：
1. 9.2.0.1.0客户端导出9.2.0.7.0的数据库下的owner

2. 9.2.0.1.0客户端导入(同一台客户端) 导入9.2.0.8 数据库服务器
$ imp ecc_view/ecc@leiz file=./leiz.dmp fromuser=leiz touser=ecc_view

With the Partitioning, OLAP and Oracle Data Mining options

IMP-00000: Import terminated unsuccessfully

    刚刚碰到这个错误的时候，以为是客户端的问题，但是在不同版本之间进行数据导入的2个规则我都满足:
规则1.   低版本的exp/imp客户端可以连接到高版本（或同版本）的数据库服务器，但高版本的exp/imp客户端不能连接到低版本的数据库服务器。
规则2.   高版本exp出的dmp文件，低版本无法imp（无法识别dmp文件）,没有问题啊，那我尝试把9.2.0.1.0的客户端换成了9.2.0.7.0的exp导出的数据库的那台服务器，但是重复imp操作后，问题仍然重现。查了metalink，原因是9.2.0.8.0平台的一个bug:
    After applying the 9.2.0.8 patchset, compilation of functions and/or materialized view refreshes that reference remote databases via database links start failing. It can occur for any PL/SQL that references a remote object via database link where the 'Endianness' of the two platforms differs. If one platform. is 'Big-Endian', and another platform. is 'Little-Endian', then this bug can be triggered between them.
    To resolve ORA-03120, this solution is given:To implement the solution, it will be necessary to apply the one-off patch for Bug 5671074 to the 9.2.0.8 database.

3.用9.2.0.8.0客户端导入9.2.0.8.0数据库服务器，问题解决。
$ imp ecc_view/ecc@leiz file=./leiz.dmp fromuser=leiz touser=ecc_view
