This value depends on the error log file settings. The maximum is 30,000 MB.
p = (s
x m) / 1024 (in MB),
where:
s is the size of the error log file (units: KB, default is 9,900), and
m is the number of error log files (default is 2). The resulting fraction will be
rounded up.
#2
This value depends on the trace file settings. The maximum is 1000 MB.
q = (t
x n) / 1024 (in MB),
where:
t is the size of the trace file (units: KB, default is 1,000), and
n is the number of trace files (default is 4). The resulting fraction will be rounded
up.
