The maximum number of bytes allowed for spool files in database_name.

n
You can enter the number of bytes as an integer, decimal, or floating point value or as a constant expression whose evaluation determines the number of bytes. You can also enter the value using exponential notation. For example, you can write one thousand as either 1000 or 1E3.
n cannot exceed the spool space parameter in the profile of the creator. If no spool space is defined for that profile, then Teradata Database uses the spool space limit defined for the individual user-creator.
constant_expression
A constant expression is any SQL expression that does not make any column references. Specifying an appropriate constant expression for the SPOOL size of a database enables Teradata Database to assign an optimal quantity of SPOOL that scales to the size of your system by allocating SPOOL space on a per AMP basis.
When you specify a SPOOL size based on a constant expression, the assigned size does not automatically scale if, for example, you add more AMPs to your system.
BYTES
Optional keyword that redundantly specifies the unit for the amount of space allowed.
