An error occurred while importing dmp exported from Oracle 11 GB to 10 Gb database. Solution

An error occurred while importing the dmp exported from Oracle 11G to the 10g Database.
(IMP-00010: Failed header verification because it is not a valid exported file) Solution

Because the server has oracle 11 GB and oracle 10 Gb locally, the dmp files exported from the server are displayed as: IMP-00010: it is not a valid file to be exported. After the header verification fails, I found the following information on the Internet. I downloaded the file and tried to modify it. I can import it. To solve this problem, I almost wanted to unload 11 GB and then install 10 Gb. Then I thought about the head verification, and I checked the dmp file with Notepad ++, I found that the header really showed some things: 11g R2: V11.02.00 11g R1: V11.01.00 10g: V10.02.01. I changed the version to the version of the sub-database of the other machine, and no error was reported when I executed imp. Consider that if the file is too large, it may fail to be opened, resulting in a crash, make a small program.
