Hi, I am trying to run postgres on unixware2.1.2. On starting the postmaster i am getting an error in shmget()... IpcMemoryCreate: memKey=155356396 , size=760632 , permission=384IpcMemoryCreate: shmget(..., create, ...) failed: Invalid argument Postmaster only starts if started with option -B 1, but i cannot still connect using pspl. I wish to know what are the expected values of various IPC parametes for postgresql and how should i set it for unixware kernel. thanks, yamini.
