I tried what you suggested but ids would not start.
It wrote out olsrvice.log with
17:27:41 Service was shut-down externally.
17:27:41 mystiq: Failure in SuMain(): WaitForMultipleObjects(): 0: The operation completed successfully.
This computer has 32gb of ram so I don't know what is going on.
May be some Windows update?
Maybe I need to go to Server 2012R2.

Hi,

We've been using informix workgroup edition on windows for some years now,
although currently on server 2012r2. Since the problem just started none of
the following may apply, but mention them in case any of it helps.

If you are logged in as the administrator account try logging in with the
informix account. If you are logged in as informix try running commands in an
elevated command prompt. I've found a few issues with some of the 'on'
commands not behaving unless using informix in an elevated command prompt,
although onstat normally runs regardless of this. You don't have a mixed case
instance name perchance, I've had that affect some 'on' commands also?

Since everything else is running it is probably not memory. Memory related you
use to have to set a few things in onconfig file, but most of that is no
longer necessary with latest informix, like SHMNOACCESS to exclude memory
ranges of the system dll's or other programs. If you've got loads of memory
you could set the SHMBASE above the 4GB mark (I think windows dll's hang
around just below there) to see if it makes a difference but again should no
longer be necessary:
SHMBASE 0x141460000L #around the 5GB mark
(we usually set this base to 0x80000000L although i think the default may be a
lot lower).
And for completeness tend to use these settings with success:
SHMVIRTSIZE 1048576 #1GB
SHMADD 204800 #add in 200mb lots
EXTSHMADD 8192
SHMTOTAL 0
SHMVIRT_ALLOCSEG 0,3

Sysinternals (now Microsoft) ProcessExplorer can show you where things have
been loaded into memory that may be conflicting...

That's all I've got.

I am on the server itself (development server) .
INFORMIXSERVER is set to the name of the instance.
The service is 9088.
IDS is running well and odbc connections run fine.
dbaccess even works.
It is just onstat, oncheck, etc.
I don't know how to do what you are telling me.

I'm not sure that you need to change IFX_XFER_SHMBASE here.

Do you have your INFORMIXSERVER value set to a network connection? If so, do
you have a shared memory connection that you can use for INFORMIXSERVER
instead and see what happens?

This is ids12.1.tc4 on windows server 2008 R2 sp1 .
This problem just started and I donââ¬â¢t know why.

When I run onstat I get this:
MapViewOfFileEx: w32ec=487 at nt_shm.c:754
09:51:19 shmat: [22]: operating system error
09:51:19 Client could not attach server shared memory segment, use
IFX_XFER_SHMBASE.
onstat: Cannot attach to shared memory. errno = 22

This article is on Linux ...

this is another
http://www-01.ibm.com/support/docview.wss?uid=swg21623474

In Windows, I presume they want me to ââ¬Åset
IFX_XFER_SHMBASE=someaddressââ¬Â .
But the conundrum is that I cannot run onstat ââ¬âg seg to get an
address
to use.
Any ideas?
