The OpenEdge RDBMS reserves space within each area for recovery purposes. The reserved space allows room for database growth during recovery. A database area can grow up to its maximum size, less the reserve recovery space indicated in the table below.

Table 1. RDBMS reserved recovery space
Block size Records per block Reserved recovery space
4096 1,2,4,8,16,32,64,128,256 5G
8192 1,2,4,8,16,32,64,128,256 5G

As an area approaches its maximum size, less the reserve, warnings are issued at 80 and 90 percent of capacity.
