Estimating transaction size

edited Sep 18, 2014 5:07AM in Database Administration (MOSC) 1 commentAnswered

Hi All, While creating table/index we can estimate the size using create_table_cost and create_index_cost, Is there a way I can estimate transaction size in 11203 ? There is a lot of DML activity going on and we keep getting "Unable to extend undotbs1" error. I cannot keep the data file size to unlimited for undotbs1. So I want to know if we can esitimate the transaction size and there by sizing the UNDOTBS1 accordingly  , e.g. the space needed for delete from where emp_code=100 , OR, delete from emp_where emp_code < 10 ; ?

Thanks
