This section applies to single-user mode only.
The data cache size is calculated with the following formula:
dbufs * ((sect + 1) * 128)
Extended initialization calls, InitISAMXtd(), InitCTreeXtd(), and OpenISAMXtd(), allow the dbufs to be specified. If non-extended calls are made, dbufs defaults to bufs (index buffers).
See DAT_MEMORY in the FairCom Server Administrator’s Guide for additional information.
