Memory is allocated for each file statically when you set up
your files and will not change unless you re-organize the files.
The meter automatically performs de-fragmentation of the
memory each time you re-organize your files. This helps keep
all free memory in one continuous block and thus prevents
possible leakage of memory caused by fragmentation.
To change the file properties or to allocate the memory for a
new file, double click on the file partition you want to change,
select desired parameters for your log, and click OK. For your
reference, the record size and the number of records available
for your file are reported in the dialog box.
To delete an existing file partition, click on Delete and then
click OK.
The following table shows how to calculate a file size for
different log files.
