Note: Verilink recommends that a 80-megabyte hard drive be used when
running Access Manager.
Each alarm record uses 62 bytes of memory, each data record uses up to a
maximum of 150 bytes of memory, and each event record uses 58 bytes of
memory. As the number of records allocated for a particular type are
filled up, the oldest records are deleted to make room for the new records.
The space used on the hard disk for data records, alarm records, or event
log records can be freed by using the
Archive option. This option
allows you to store records to diskette and/or delete the records entirely.
Each of these three types of records (data, alarm, event log) has
associated .DAT and .KEY files. To decrease a record’s associated .DAT
and .KEY files to minimum size and thereby release disk space, all
records of a type (for example, all alarm records) must be deleted from
the database.
To minimize the space used for data collection, the program stores only
records that are non-ZERO.
