Setting Kernel Parameters
Before installing OVO on UNIX systems, make sure the kernel
parameters are set correctly. Although system default values are
normally sufficient, the logfile encapsulator sometimes requires that the
number of open files be increased.
Table 1-1 gives values for kernel parameters on HP-UX managed nodes.
Other UNIX-based agent platforms generally require similar values.
NOTE For information about recommended kernel parameters for Sun Solaris
managed nodes, refer to the Chapter "About Sun Solaris Managed
Nodes" of the OVO DCE Agent Concepts and Configuration Guide.
Table 1-1 Important Kernel Parameters for Managed Nodes
Parameter Description Minimum Value
nfile Maximum number of open
files.
semmns Required semaphores. 20
20 a
shmmax Maximum shared memory. None required.
msgmni Message queues. None required.
nflocks File locks. 10
a. This number depends on several factors. Normally a value of
20 per process is sufficient. However, the more logfiles that
are configured for the logfile encapsulator, the more file
descriptors are needed. Normally, one logfile requires about
one file descriptor. Any actions that result in processes being
started on the managed node need additional file descriptors.
