Freeing Space on Cylinders
In addition to MiniCylPack and AutoCylPack, you can use the following to free space
on cylinders or to make more cylinders available to the system:
FreeSpacePercent (FSP) (see “PACKDISK and FreeSpacePercent” on page 525)
PACKDISK (see Utilities)
Cylinders to Save for Perm (see “Cylinders Saved for PERM” in Utilities)
Temporary space limits on users/profiles.
Spool space limits on user profile definitions:
Set larger spool space limits.
Minimize the number for individual users to limit runaway query spool space.
Both of the above will not necessarily stop space management routines such as MiniCylPack
from running, but it could help manage the area.
Archival and deletion of aged data
Planned deletion of obsolete rows facilitates space availability. Depending on the
nature of your data, you may want to archive before deleting. For more information,
see Teradata Archive/Recovery Utility Reference.
Appropriate data compression (see “Data Compression and Performance” on page 527)
Additional disk space
Appropriate data block sizing:
Maximum block size allocation
Minimum block size allocation
Journal data block size allocation
