Installing SoftBench

Prerequisite Details
Kernel Parameters
Appendix A62
Kernel Parameters
For initial use of SoftBench, you may not need to change kernel
parameters. It is recommended that you finish installing and verifying
simple SoftBench operation before modifying kernel parameters. This is
because modifying these parameters necessitates regenerating the
kernel, and regenerating the kernel at the same time that you install a
product makes troubleshooting problems much more complex.
To avoid exceeding the default limits for certain kernel resources and
incurring possible loss of data during heavy SoftBench use, check the
recommended values in the following table for configurable kernel
parameters. See the HP 9000 System Administration Tasks manual for
default values and further details.
Table A-1 Recommended Kernel Parameter Values for SoftBench
Parameter Description Recommended Value
maxdsize Maximum data
segment size.
128 Mb or higher is
recommended. maxdsize
should not exceed available
swapspace. Setting maxdsize
equal to RAM is
recommended. Default is
adequate only for light usage:
small programs, one task at a
time.
maxuprc Maximum number of
processes that a user
can run
simultaneously.
Default value + 50
nproc Maximum number of
processes that can
exist on the system
simultaneously.
Default value + 30 per
concurrent SoftBench user. In
addition, the following should
be true: nproc >
(maxuprc+30)
