You'll probably get a zillion responses to this, but let me just be one of them. The raw device needs only to be 660, but it should be owned by informix and have group ownership informix. > - This means everybody can see what is in the database.

That's why it should be 660. >My second surprise was when I saw the size of compiled 4GL code. >These are +/- 300K. So I went looking for a shared library for >Informix, but didn't find it. Can Informix use shared libraries? Unfortunately not at this time.
