Your shared memory segments may not have cleared properly. Run onclean -ky command. This should hopefully clear any lingering shared memory segments.

If this doesn't work, run ipcs command to identify the memory segments and remove using ipcrm


Make sure you have rights 660 on your ROOTPATH file, see the location on $INFORMIX/etc/[your_onconfig].

Launch oninit -ivy for more details or see log on your MSGPATH file.
