I had a few thoughts about how you can find out what happened on the
production box:
If the system itself went down, the system log /var/adm/syslog/OLDsyslog.log should have entries for the period before the crash. Also, did the sys admin have any of the HP monitoring software running, which is quite comprehensive, and have they checked the relevant diagnostic logs and its mails to the superuser?
I can't remember exactly, but I seem to recall that the install used to need about 400MB free in /tmp. If you had the amount recommended free, then the crash probably - definitely - or even possibly came about because the box itself ground to a halt.
If so, I have seen this before and it looks to me as though the system may have run out of processes it can allocate, and the sys admin needs to tweak / increase key HP-UX kernel parameters in line with the configuration of the box i.e. number of cpus, memory etc. If swap is needed, the sys admin can add this dynamically using sam, with no downtime needed.
I have 8i and 9i running on an HP L2000 - now an RP5470 - and had no trouble installing 9i, although I did take a copy of the entire system and put it on our Sap upgrade test box first to see what happened. (I suppose that I am 'lucky' in that I do the sys admin and oracle dba work, so I get to tweak things to see what effect it will have.)
My advice in sys admin mode is: get the sys admin to contact HP as they have a great paper on configuring HP-UX to run oracle, including algorothms for correctly calculating the values for key kernel parameters relating to the number of oracle instances running, number of users, recommendations as to swap space size etc, get them to do the work - and then shoot them. I recommend this course of action because I am presuming that you told them what you were going to do, and they didn't act in response to your notification. (I have been in this position myself, but had great difficulty pointing the finger at me afterwards.............!!)
Personally, I would be interested to hear from anybody here with experience of Sap, who may know of ways to reduce the current time taken (48 hours), to update the tables PPOPD (@ 2.76 million rows) and PPOIX during a local client copy.
