Set the tablespace parameter. Use the following formula to determine the value: 2 MB x (number of tables in each scan x number of concurrent scans)
For example, you have 1,000 tables in each scan and you plan to run 10 scans concurrently. Calculate the tablespace parameter value as follows: 2 MB x (100 x 10) = 20 GB
The tablespace must be distributed across multiple disks.
