Chapter 6 HPSS Configuration
352 September 2002 HPSS Installation Guide
Release 4.5, Revision 2
Solaris
When running the Mover or non-DCE Mover process on a Solaris platform, there are a number of
system configuration parameters which may need to be modified before the Mover can be
successfully run. The values can be modified by editing the /etc/system configuration file and
rebooting the system. The following table defines the parameter names and minimum required
values.
Note that the semmns and semmnu values should be increased if running more than one Mover
on the Solaris machine (multiply the minimum value by the number of Movers to be run on that
machine).
Linux

system configuration parameters which may need to be modified before the Mover can be

values.
