4-7 Setting kernel parameters and shell
restrictions
Before installing the Device Manager server, you must set the OS parameters (kernel parameters
and shell restrictions). If the kernel parameters have not been set correctly, installation fails.
When you uninstall the Device Manager server, you must change the kernel parameters and shell
restrictions back to the previous settings specified before the installation of the Device Manager
server.
The following describes the procedure for setting the kernel parameters and shell restrictions in a
Linux environment.
Before changing kernel parameter settings and shell restrictions, back up the /etc/sysctl.conf
file and /etc/security/limits.conf file. You can use the backup files to restore the previous
kernel parameter settings and shell restrictions after you uninstall the Device Manager server.
Table 4-8 below shows the recommended values for the shell restrictions and Table 4-9 shows the
recommended values for the kernel parameters you must set.
Refer to these two tables, to set the shell restrictions and kernel parameters according to the
following formula (in the formula, "Max {x, y, z}" means using the maximum value among x, y, and
z).
