Estimating Required Memory
To calculate the required memory for HRUDCRX, start with 170 kB, which is
the basic requirement. Add to that the variable requirement, which is
calculated as follows:
(A + B + 2,112 +C * (5D + 1,024)) / 1,024 (kB)
A is either 160 (if you are using JOB stream input) or 5 * the block length of
the SYSIN dataset.
B is either 242 (if you are using SYSOUT output) or 5 * the block length of the
SYSPRINT dataset.
C is either 1 (if you are specifying a RAIDPARM dataset) or 0.
D is the block length of the RAIDPARM dataset.
