Thanks for your reply. Here are the Export and Import messages.

EXP-00008: ORACLE error 1555 encountered
ORA-01555: snapshot too old: rollback segment number 21 with name "R20" too small

after the above error, there are many tables are exported without any errors. But while doing import, I am encountering the below error. I am just trying to importing remaining tables, which are exported after the above error. Below is the import error:

IMP-00009: abnormal end of export file.

Thanks In advance.
