Notes for Table 55:

1. Only one database at a time can be operated in multiple user mode.
2. This is the absolute maximum value. The practical maximum value is less, depending on the values specified for other parameters and system resources (such as the amount of storage available). The maximum number of NCUSERS is limited because the program stack storage for each real agent is obtained below 16 megabytes.
3. These are 4 K pages.
4. These are 512-byte pages.
