You are probably confusing two things. Sometimes it happens a record doesn't
fit in the import buffer. Just include and/or increase the buffer parameter
for imp and you should be fine.
You can't change the db_block_size without creating the database. Note: If
you have multiple tables with records exceeding 2k, you will get chaining
(one record in multiple blocks). In that case changing the db_block_size
will be advantageous.
If this doesn't resolve the problem, please post the EXACT error message.
