HP-UX 10.20/IDS7.30UC crashes machine ✓ Answered: green (hollow confidence) — Original asker confirms the machine stopped crashing after installing all recommended HP-UX patches (an engine upgrade to 7.30UC6 alone did not help), matching an earlier suggestion from another list member; asker himself hedges that another simultaneous change might also be responsible.

Advisory only.

Hello, we have some problems with the following configuration: HP-UX 10.20 IDS7.30UC cooked files on a RAID-LEVEL-5 We initialized (oninit -i) the online system and added some dbspaces. But now we have a big problem after startup (oninit). After typing oninit (between 0 seconds and a few minutes) the machine hangs and do a automatic reboot. Is this a known problem? Some ideas to fix this problem?

Ich weiß leider nicht genau die Umstände, die zum Crash führen, aber es gibt zwei mögliche Ursachen. Variante 1 ) Ihr habt NOAGE nicht eingeschaltet und HP hat ein Problem mit der zeitgesteuerten Prioritätssteuerung. Variante 2 ) Informix allokiert ein zweites virtuelles Segment, und bekommt dabei seitens HP ein Problem. Wenn aber HP einen Reboot durchführt, so ist es auf jeden Fall ein Betriebssystemproblem. Viel Spass und einen guten Rutsch ins neue Jahr Stefan Weideneder

Well - it's elimination time. Start by eliminating ipcstr. The strings interface is a newer feature on both HP and Informix. Next - check your memory utilization. Since this is happening after booting the system and you are bringing the engine online, I'm guessing that as you are getting shared memory segments that you are possibably running into a memory issue. Next - eliminate KAIO. KAIO requires that the memory segments be pinned in memory while the IO is underway. It's possible that HP is allowing the address to be paged and getting into trouble because the physical memory address is not there when the IO completes. If eliminating KAIO works, then you might try to make the shared memory segments resident. >Hello, > >we have some problems with the following configuration: > > HP-UX 10.20 > IDS7.30UC > cooked files on a RAID-LEVEL-5 > >We initialized (oninit -i) the online system and added some dbspaces. >But now we have a big problem after startup (oninit). > >After typing oninit (between 0 seconds and a few minutes) the machine >hangs and do a automatic reboot.

Hallo Volker, we had similar problems on HP-UX lately. We changed to 7.30.UC5 and !!!! got all HP UX Patches onto the system and - without knowing why - the symptoms you described disappeared. Klaus Nonne nsi001@aol.com

Hello, here is the solution for my descibed problem. First, we installed IDS 7.30UC6; nothing happened; means the machine continues crashing Second, we installed all recommended patches (HP-UX); what a surprise: our machine stops crashing.
