You are recommended to place the following settings in file /etc/sysctl.conf:
kernel.msgmni=128 #Max # of msg queue identifiers
kernel.msgmnb=163840 #Size of message queue
kernel.msgmax=40960 #Max size of a message
- On Red Hat, the new settings are used after you restart the computer.
- On SuSE, issue the command chkconfig boot.sysctl
on, and then reboot.
- To check that the new settings have been applied, issue the command sysctl
-a.
The
MSGMNI variable determines the maximum number of
message queue identifiers system wide. This is typically set to 128 which
is sufficient for the normal number of concurrent requests expected to be
processed.
