accomplished by running host processing with the STAT mode SOUPIN parameter set. This will
produce a record count that is the base for all calculations. (See Appendix B)
The output of the STAT mode run of the biggest report is a. Multiply a times 512 to get b, the
number of bytes in the CSJ files. Add another 5MB to account for the other files (Metadata,
CACMD), this yields e, the actual disk space required. Multiplying e by a growth factor g (in this
example 1.5) yields H, the recommended amount of disk space, in bytes, to be added to the
host.
Formula
a * 512 = B
b + 5,000,000 = e
e * g = H
Where
- a = Record count of largest report in output from STATS mode run. (If running
in a SUN environment, turn on multi-threading to create all of the groups at
the same time)
- b = number of bytes in the CSJ files
- e = amount of raw data to be loaded into database
- g = Growth factor
- H = Recommended additional host disk space
The summation of the output of the STAT mode run is A. Multiply A times 512 to get B, the
number of bytes in the CSJ files. Multiple number of Presentation Groups, C, by 5MB to account
for the other files (Metadata, CACMD). This yields D. Add B and D to arrive at E the amount of
raw data in bytes that is loaded into the database. An SQL database uses disk space that is
about 1.8 times the amount of the raw data. Multiply E by 1.8 to arrive at F, the number of bytes
in the SQL database. Multiply D by a growth factor G to arrive at S, the recommended amount of
disk space in bytes in the SQL database for 1 snapshot.
Formula
A * 512 = B
C * 5,000,000 = D
B + D = E
E * 1.8 = F
G = Growth factor
E * G = S
