Hi Guys,I need assistance in upgrading my client's progress 9.1D SP06 to SP09 running at compaq tru64 machine as there were a few errors occurs throughout the process. Firstly, the error occurs while i'm trying to mount the disk with following command:mount -t cdfs -o noversion [device_name] i.e. /dev/rdisk/cdrom0a. As a results of the failure,I copy the .tar file to the machine with ftp and trying to unzip in the tru64 machine with tar -xf [file_name].tar commandit failed too with error message saying no enough space for memory allocation.next,i unzipped the .tar file with winRar in Windows and copy over to the tru64 machine,and start to run the ../../proinstit failed too with error message saying could not execute the /_ovrly file, the installation terminates abnormally and prompted me to delete the file I have checked the knowledge base with the error messaged displayed, it says the file is corrupted. I'm downloading a new one from progress site, but at the mean time, i don't fully believe it was caused by corrupted file.Please look into this and spare me your helping hands soonest possible.
