故障分析及解决过程
imp导入报错：
IMP-00051: Direct path exported dump file contains illegal column length
IMP-00008: unrecognized statement in the export file
IMP-00009: abnormal end of export file
1 2 3 4 5 6 7 8 9 | [oracle@lhrdb ~]$ oerr imp 51 00051, 00000, "Direct path exported dump file contains illegal column length" // *Cause: An invalid column length was encountered while processing column // pieces." // *Action: Check to make sure the export file is not corrupted, or else // report this to Oracle Worldwide Support as an Import/Export // internal bug and submit the // export file. |
由于使用了direct=y的方式导出，所以导入的时候报错。MOS上是针对分区表的某一个空的分区导入的时候会报该错，但是客户这边的表不是分区表，dmp文件太大，不能做具体原因分析。给出的解决方案为：针对报错的表单独导出，并采用parfile参数。
1 2 3 4 | [ZFZHLHRDB1:oracle]:/oracle>more /tmp/scottfile.par tables=scott.emp,scott.dept exp \'/ AS SYSDBA\' file=/tmp/test_query_lhr_scott_01.dmp parfile=/tmp/scottfile.par log=/tmp/test_query_lhr_scott_01.log |
参考的MOS文档：
Traditional Import (IMP) Raises Error IMP-51 Direct Path Exported Dump File Contains Illegal Column Length (文档 ID 1403865.1)
ALERT Direct Path Export (EXP) Corrupts The Dump If An Empty Table Partition Exists (文档 ID 1604983.1)
The traditional export utility is de-supported beginning with the version 11g and is no more maintained.
exp和imp从11g开始不再维护。
