Cannot attach to shared memory after DB restore?

I hope someone out there knows the answer to this: the problem is i have a UnixWare 2.11 machine (90 Mhz, don't know memory... but could check if u think it is important) on this UnixWare, we have loaded some informix, and applied and upgrade to informix, so the informix we are running is: 4gl Interactive Debugger version 4.14.UC1 4gl version 4.14.UC1 4gl Rapid development system version 4.14.UC1 sql version 4.14.UC1 Online engine version 5.03.UC1 (the order i listed them is almost the order in which they were applied... all application tools are installed before the engine) the problem is the engine comes up and tbmonitor shows 3 databases. isql and dbaccess can not see the engine, typing dbaccess and hitting return results in : 529: Cannot attach to shared memory. 22: Invalid argument informix guys had me start a second instance of the engine in case the first engine is screwy (cuz i did a restore of my old database) but even the second engine instance had the same problem. informix thought it was a kernel problem. SCO UnixWare people say NOT. informix thinks SCO did a kernel release and forgot to tell informix that there IS something different so informix would have to port to the new one and make a patch of some kind..... thanks, nj
