Re: Shared Memory question - Abhay Mannur.

The informix install directory will contain some files under the root's ownership (I used to carry a list of those files, but they have changed in 7.3). But, the shared memory segments should be removable by informix. After finishing the installation, the script fixes the file ownerships and most of the files are owned by informix:informix. The installed files have nothing to do with the shared memory segments. Who owns the informix shared memory segments depends on who brings up the server - root or informix. So, whoever owns the segments only can drop them too. If you install informix as user informix, some of the stuff won't work properly and some others don't even run.
