attatching?

First place I would go would be the operating system. Have you made any
kernel configuration changes as recommended in the IDS.DOC file? Assuming
you are starting the engine as informix does it have permissions to create
shared memory segments? Is this a second (or third or forth) instance on a
single box? If so have you used a different server number? The shared memory
identification and addressing is taken from the server number.
Do you have sufficient memory to created the segments of the requested size?

Joe;
The most frequent cause of this error is when the shared memory segments
you are trying to create when starting the engine already exist.
Look in the online log for an error 17 - that means the segments already
exists.
That means either the engine is already running (run 'ps -ef' and look for
any oninit processes running), or shared memory segments have been left
orphaned by the operating system even if the oninits aren't running.
Run an 'ipcs -m' and look for a segment with a key starting with 5258.
Specifically, 52584801.
If that exists, you'll have to remove it (them) before you start your
engine (see your System Admin for that).
HTH...
