No, although you could take all the other rollback segments offline before starting the Import. The better solution is to use the COMMIT=Y and BUFFER= parameters of Import. By default, Import doesn't issue a commit until the table has been fully imported. If you set BUFFER equal to 100000, and use COMMIT=Y, then the rows will be committed every 100000 bytes - requiring drastically less rollback segment space. If BUFFER is set too small, you'll get IMP errors - I think IMP-00020. If that happens, clear out the imported records, and Import again using a higher setting for BUFFER.
