The following request creates PERM space for a user with a size based on the constant expression 2,000,000 (HASHAMP()+1), SPOOL with a size based on the same constant expression 2,000,000 (HASHAMP()+1), and TEMPORARY with a size based on the constant expression 2,000,000 (HASHAMP()+1). The expressions calculate the number of AMPs in the current system and scales the PERM, SPOOL, and TEMPORARY space for the sls120639 user to that size.

     CREATE USER sls120639 AS
       DEFAULT DATABASE = it_dev,
       PASSWORD = (EXPIRE = 0),
       PERM = 2000000*(HASHAMP()+1),
       SPOOL = 2000000*(HASHAMP()+1),
       TEMPORARY = 2000000*(HASHAMP()+1);
