Re: Number maxim of concurrent conexions

Hi,

you may see some errors in the online.log (message) file of the server.

If users already "point to" 'can not open more files' and as it is with
sockets/tcp protocol only, I'd definitely look in that area (i.e.
respective
UNIX kernel parameters) ...

Regards,
Martin

I have defined shm and tcp, for shm run ok, but for tcp not ok.
I don't know the ifx error because I can't reproduce it.
The users say me than the error is 'can not open more files' more or
less.
I don't know if the problem is for the system can't allocate more
socket, or if the problem is for any parameter del /proc (max-file...)

Hi,

the only place where IDS actually enforces number of connections
is via the NETTYPE parameter in onconfig file. Please see the
manual for more information on this (or past e-mails in this list ...
:)

However there are other possible reason for a restriction:

- number of open files when soctcp connection protocol is used,
because for each socket connection a file descriptor is needed.
This usually is an OS parameter.

- SHM (segment) limitations when ipcshm protocol is used.
Each SHM connection needs some SHM in the "message segment(s)".
If running out of SHM it will impose a limit.

That's what currently comes to my mind.
The actual error and circumstances may reveal more insight.

Martin

Hello:
I have a problem when in my IDS 9.40 in Linux System 32 Bytes have
more
than 1100 conexions.
Which is the max conexions for IDS? There are any parameter in the
Operatym System for more conexions or only it's a limit of Informix?
Thank you
