MBX_HELPER Aegis MBX_HELPER
NAME
mbx_helper - Establish ability for inter-node interprocess communication
DESCRIPTION
mbx_helper is a program residing in the /sys/mbx directory of your node
which, when executed, allows your node to handle interprocess
communications with other nodes (also running mbx_helper) in your
network. Normally, this program runs in a background process, and is
started automatically by programs which require its services (like SPM,
the Server Process Manager). You may start it manually, if you wish, by
using the DM commands cpo or cps either from the keyboard or from within
a DM startup script. You should probably use cps so that the process
persists across user logins and carries a system SID. See help cps for
more information.
mbx_helper takes a standard CL command line with the following options:
-maxchan channels Specify the maximum number of remote channels
to/from this node using mbx. The default is 128.
-datasize byte_count Specify the queue data size for each channel. This
is the maximum number of bytes that can be buffered
at one time for remote mbx channels. The default
is 1158.
Startup File
When programs such as spm start mbx_helper automatically, they check for
the file `node_data/startup.mbx_helper and read it if it exists. This
startup file may contain either or both of the options described above,
plus comments prefixed by the shell comment character '#'. If the startup
file does not exist, mbx_helper executes using the default values for
both options.
EXAMPLE
cps /sys/mbx/mbx_helper -n mbx_helper
This starts the server with the default channel and queue data size
values. The -n option applies to the cps command and assigns a name to
the new process.
