We have Informix 9.21 UC5 running on Solaris 9 and are peridically(a couple of times per week) receiving an assert failure, which produces an af file which we so far have not been deleted before we can copy it. The errors in the message log are as follows:

02:36:27 semctl: errno = 22

02:36:27 semctl: errno = 22

After this happens we usually reboot the server.


Any ideas would be appreciated. We do not have Informix support.

Mark

I do not know if this helps the error semctl errno = 22 means that it has attempted to use a semaphore that does not exist. Any connections using shared memory connections need to have a portion of a semaphore to store the connection information. If you run ipcs -s it will list the current seme

Assuming you went throught the machine notes to update the kernal you might want to try staying away from shared memory connections and only use tcp connections.

Tech support would be the best to solve this issue, which I am not part of.

If you have support for Solaris you might want to contact them to see if they can help with the semctl error.

HTH

look in /tmp/af.3f300f3 .
Inside you can get more information, like: what session cause the problem and what the stack of the session.

So then , you can look on IBM site if not there is a bug relation .

Can anyone tell me what i need to do to convert a UNIX Informix installation to a Windows Infomix installation. I was provided a tar file and extracted it with Cygwin. We go to import it and and it doesn't seem to work. Do we need to convert the UNIX format to a Windows format. Any help would be much appreciated.
