RE: DB size
You need to split the database in order to overcome the DOS limitation of 4
GB. In the Service System FAQ: F-DK-DIAS-LANI-00003 you can find detailed
information.
Here is an extract.
Fist create a textfile with the name c_data@.dat. Syntax for this is:
path-0 splitno-0 maxsize-0 priority-0
path-1 splitno-1 maxsize-1 priority-1
path-2 splitno-2 maxsize-2 priority-2
: : : :
path-n splitno-n maxsize-n priority-n
There can be up to 15, since it's possible to split into 16 files
Lines starting with ; or # is considered remarks.
path: Path to splitfile x (c_data.xxx, c_data1.xxx, ...)
split-no: Number on "split" (0-15)
maxsize: "max" size. Is this overruled split 0 is used with out any other
split def. considered.
prioritet: Used as a guideline for priority between splits and the
extention of the database. Splits with equal priority will be divided
eaqualy.
Example:
;
; Splitfile definition (c_data@.dat)
;
/disk0 0 100 10
/disk1 1 200 15
/disk2 2 200 15
/disk3 3 100 12
-----------------
Med ovenstående kan man lave en meget stor Native database, men hvis man har
brug for splitfiles, så bør man køre på SQL.
Hvis der opstår fejl i en splitfile installation, er det næsten umuligt at
redde data, så man skal minimum være sikker på at man styr på sin backup
strategi og eksekvering.
