I'm running Xenix 2.2.2 on a PS/2 60 with 2 meg of memory.
I'm developing a commercial application which uses SysV
message queues to pas info. between two servers and a
variable number of other processes.
I have attempted several times to increase the kernel allocation
for message queues, but never manage to get more than 8192 bytes.
The parameters I'm changing are:
MSGMNI 10
MSGSSZ 8
MSGTQL 60
MSGMAX (MSGSEG*MSGSSZ)
MSGMNB (MSGSEG*MSGSSZ)
MSGSEG 0
the numbers to the left are default values. MSGSEG is altered at boot-up
time depending on the amount of memory.
I would like to get around 200 messages (MSGTQL) and 100K bytes of
total size (MSGMNB?). Every alteration I make to the parameters
either gives me 8k or 0 bytes. Does anyone know how to do this??
I need to solve this soon so email is fine ( ..!uunet!sean!news ).
Thanks in advance,
Mike Anderson,
