Minimum system requirements for the Solaris kernel when used with VERITAS NetBackup (tm), defined in /etc/system

--------------------------------------------------------------------------------
Details:
This document states the minimum system requirements for tuning Solaris kernel parameters to work with NetBackup. VERITAS only provides this information as a basic starting point, as this is actually a Solaris OS configuration issue that is also impacted by other applications running on the system.

If /etc/system already contains one of these entries, use whichever value is larger for that setting. Before modifying /etc/system, use the sysdef command to view the current kernel parameters. Add the following lines to /etc/system and reboot for the settings to take effect. After rebooting the sysdef command should display the new settings:

---------------------------------------
* Message queues
set msgsys:msginfo_msgmap=500
set msgsys:msginfo_msgmax=8192
set msgsys:msginfo_msgmnb=65536
set msgsys:msginfo_msgmni=256
set msgsys:msginfo_msgssz=32
set msgsys:msginfo_msgtql=500
set msgsys:msginfo_msgseg=8192

* Semaphores
set semsys:seminfo_semmap=64
set semsys:seminfo_semmni=1024
set semsys:seminfo_semmns=1024
set semsys:seminfo_semmnu=1024
set semsys:seminfo_semmsl=300
set semsys:seminfo_semopm=32
set semsys:seminfo_semume=64

* Shared memory
set shmsys:shminfo_shmmax=16777216
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=230
set shmsys:shminfo_shmseg=100
---------------------------------------

The parameters listed below are obsolete in Solaris 8, but are still valid in Solaris 2.6 and 2.7:

set msgsys:msginfo_msgssz = The size of the message segment in bytes (multiple of word size).
set msgsys:msginfo_msgmap = number of elements in the map that is used to allocate message segments message map.
set msgsys:msginfo_msgseg = maximum number of message segments. The kernel reserves a total of msgssz * the msgseg bytes for message segments and must be less than 128 Kilobytes. Together msgssz and msgseg limit the amount of text for all outstanding messages.
set semsys:seminfo_semmap = number of entries in semaphore map
set shmsys:shminfo_shmmin = minimum shared memory segment size
set shmsys:shminfo_shmseg = maximum number of shared memory segments that can be attached to a given process at one time

If the values are present in the /etc/system file on a Solaris 8 or 9 system, the operating system will ignore them.
