It is absolutely 100% nothing to do with SAP. It was a routine upgrade to z/OS mainframe job scheduling software.

It is software that is used worldwide by major banks, insurance companies, building societies, governments etc... for scheduling 'batch' processing.

Beorhthelm's comments are pretty close to the basic story.

In 28 years of working on IBM mainframes for large corporations, I have never seen the combination of several elements, each on their own fairly common and manageable, cause such a fundamental and challenging disaster area.

It is usually the simplest things that cause these problems as they tend not to get tested thoroughly.

I once found a bug in the scheduling software we used whilst User Acceptance testing - essentially it could not cope with running more than 1 batch cycle in a day - we started the second cycle at about 5 to midnight (yup, we were working hard) and every job started running at once!! Oops.

I don't know... but I rather suspect 'Oops' was not the word being used in this case!
