impdp中遇到的两个问题

impdp导入时出现了一下错误：

Processing object type SCHEMA_EXPORT/TABLE/INDEX/INDEX

ORA-39014: One or more workers have prematurely exited.
ORA-39029: worker 1 with process name "DW01" prematurely terminated
ORA-31672: Worker process DW01 died unexpectedly.

Job "PHSI"."SYS_IMPORT_SCHEMA_01" stopped due to fatal error at 01:29:59

运行df -h，发现根目录使用率100%了，当时用sys用户登录不进去，提示 no space，在根目录下删除两个文件，再次登录成功。

重新导入，又出现的如下错误：

Processing object type SCHEMA_EXPORT/TABLE/STATISTICS/TABLE_STATISTICS
ORA-39125: Worker unexpected fatal error in KUPW$WORKER.PUT_DDLS while calling DBMS_METADATA.CONVERT [TABLE_STATISTICS]

有人说是10.2.0.1的BUG，当时使用的版本如下：

Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options

统计信息不导入也没关系，我们可以导入后手动收集统计信息，可以在impdp中添加/TABLE_STATISTICS参数规避该错误。
