Windows platform stability

[Former Member]

Hi Gurus,

My SAP system is running on Windows 2000 advance server.

It reboots by itself quite often but ad-hoc, eg. once a month on average. Either the Apps server crashed and rebooted by itself or the database central instance.

I never had such obvious problems on unix platform. Is this likely a windows platform related issue or could you suggest , based on experience, how is this form of crashing possible?

Is it true that heavy duty batch jobs such as monthend processing could possibly lead to such problem?

Could you hint about the logic behing why/how abap could

cause system to reboot itself and suddenly, i.e. windows O/S could not log a system trace in events log as to what happened, a.k.a event log: "...the last reboot was unexpected..."

Pls help me a little on how to save my server and many nights of firefighting. Many thanks.

sincerely,

Pascal Gabin

Hi,

You don't specify the type of machine. It is best to check the requirements at service.sap.com/quicksizing. It'll calculate the machinery. service.sap.com/platforms will ellaborate on the specific OS/SAP combinations.

Hi Pascal:

First, you must consider several factors; one key factor is hardware; mostly Windows will crash in that way because something is wrong with the hardware; some cases it could be memory faulting other times even disk drive.

I think can I help you but you should send me more information about hardware and software configuration.

I will suggest go through a deep hardware checking and if necessary software. Mostly if the system is not showing a "Blue Screen" it could be memory errors; check memory...

Seriously, is unlikely to happen an unexpected crash in a Windows 2003 Server. Pretty stable! I can assure that!

Hope this helps!

You need to get your OS guys to troubleshoot.

I've worked at large comapines that run highly intense, huge databases on W2000 boxes without any problems whatsoever. I've also worked in UNIX environments where servers crashed unexpectedly. I'm no fan of Microsoft, but you can't just automatically blame Windows. There is always a valid reason behind the crashes.

The trick is to follow SAP and db installations precisely, and install ONLY unecessary apps on the box, to avoid Dll-hell. And if you've got flakey hardware, it's going to crash whether you're on UNIx or Windows. Your Infrastructure guys should be able to troubleshoot.
