Calculating disk requirements for a dictionary
You can calculate the disk requirements for a dictionary that is associated with a compressed, nonsegmented table space, or a compressed, segmented table space.
Procedure
To calculate the disk requirements for a dictionary:
Determine your table space type:
- Non-segmented table space
-
The dictionary contains 4096 entries in most cases. Fixed-length compression dictionaries require additional sixteen 4-KB pages, eight 8-KB pages, four 16-KB pages, or two 32-KB pages. Although it is possible that your dictionary can contain fewer entries, allocate enough space to accommodate a dictionary with 4096 entries.
- Segmented table space
- For segmented table spaces, additional space might be required based on segment size and page size.
