DBVCLOSE <number> SE sessions
Ускоряет работу в SE с многотабличными
запросами. По умолчанию 12.
" DBVCLOSE is used only for SE to control number of file descriptors associated
with table open at a time. If this environment variable is not set then default value of
12 is assumed. This limit is enforced by ISAM level and not by SQL level. i.e. if your
query involves join of 8 tables and DBVCLOSE is set to 4 then SQL would open all tables.
Limit imposed by DBVCLOSE is only checked by ISAM level at table close time. "
