Table 31 and Table 32 list approximate values for each calculation component for
single and multiple users running an OpenEdge installation.
Table 31: Single-user memory requirements
Component symbol Memory
_progres 3MB–4MB 1
1. This is an approximate value. Use the size command to determine the exact size. If you are using a
non-OpenEdge database, your value will be larger.
Table 32: Multi-user memory requirements
Component symbol Memory
