Exp export data, reported EXP-00003: Not found segment (12, 11) Storage definition, looked up from the Internet, there are two main reasons:

1. Version problems, that is, the client and server versions are the same, while I only have minor version numbers that are inconsistent and should not be wrong.

Finally, find a solution:

When exporting data, You must select comporess = true to export the data normally.

 

The data is being exported and has not yet been imported. Import the data to the database during import (pilot import structure, and then import the data ):

After the structure is imported
Import table alter table r_tst2.r_general_ply_main storage (maxextents unlimited );
