If anyone has any experience with running Progress on an HP-UX platform, I am looking for some feedback on the following limitation: If two processes attempt to read the same file directly from disk, one process will have to wait for the other to finish before it can begin its read, because there is only one file handle to pass around. This essentially equates to "single-thread" reads at the OS level. Any info would be appreciated Bruce Bonacci LDP, Inc. [log in to unmask]
