(2) Disk Capacity Requirements

Table 3-16: Disk capacity requirements for a host lists the disk capacity

requirements for a host.

Table 3-16: Disk capacity requirements for a host

#1

100MB of free capacity is required in

/var/tmp

during installation.

#2

This value depends on the error log file settings. The maximum is 30000MB.
p = (s 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.

#3

This value depends on the trace file settings. The maximum is 1000 MB.
q = (t 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
