I am having fun trying to get onbar to work on IDS 9.40 running on
Linux.

Whenever I run onbar -b -L I get shmdt: errno = 22, and the
bar_act.log indicates that onbar has completed with code 156. Where
can I find what these error codes mean?

As to the shmdt error I have observed that there is a segment of
shared memory owned by Informix which does not get removed when I stop
the engine. It has a status of dest.

There do seem to be rather a large number of segments (>20) for such
a small system.

I would include the ONCONFIG file but there is no link between the
Linux server and the network.

regards

Malcolm
