IMP-00010: not a valid export file on oracle import, header verification failed

IMP-00010: not a valid export file on oracle import, header verification failed

Problem description:

IMP-00010: not a valid export file on oracle import, header verification failed

Import the dmp file exported by oracle 11g into oracle10g

Problem: import table operation, prompt:

IMP-00010: not a valid export file, header verification failed

IMP-00000: import was not terminated successfully

Solution:

Query the oracle version number in the dmp backup file, the major version number must be the same, otherwise it will not succeed.

Consider using editing software such as notepad++/UE/editplush to open the dmp file and modify it

To make it clear that the backup mode of dmp is exported by the exp/expdp/ tool, import the imp/impdp/ tool in a relative way

The most important thing is to find out who is the table user before the dmp file to be imported. The user should be created in advance in the machine to be imported, otherwise it may lead to unsuccessful creation of views, triggers, etc.

The method of querying the oracle version number is posted below:
