This example creates PERM space for a user with a size based on the constant expression 2,000,000 (HASHAMP()+1), SPOOL space with a size based on the same constant expression, 2,000,000 (HASHAMP()+1), and TEMPORARY space 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 scale the PERM, SPOOL, and TEMPORARY space for the sls120639 user to that size.
This is the original definition of user sls120639.
CREATE USER sls120639 AS DEFAULT DATABASE = it_dev, PASSWORD = (EXPIRE = 0), PERM = 2000000*(HASHAMP()+1), SPOOL = 2000000*(HASHAMP()+1), TEMPORARY = 2000000*(HASHAMP()+1);
The following MODIFY USER statement changes the PERM, SPOOL, and TEMPORARY space allocations for this user as follows.
MODIFY USER sls120639 AS DEFAULT DATABASE = it_dev, PASSWORD = (EXPIRE = 0), PERM = 3000000*(HASHAMP()+1), SPOOL = 3000000*(HASHAMP()+1) TEMPORARY = 3000000*(HASHAMP()+1);
