Errors in IBM's DB2 cause weeklong bank outage
InfoWorld | at | by Mike
Flaws in IBM's DB2 database software were responsible for a chain of glitches that turned a routine hardware repair into a weeklong operational crisis, Danske Bank said Thursday in a report on an outage it suffered in March. The Copenhagen-based bank, Denmark 's largest, was replacing a defective electrical unit in an IBM RVA (Ramac Virtual Array) disk storage system used for DB2 data when an electrical outage in the system halted operations at one of the bank's two IT centers. Several hours later, the system was repaired and restarted. But the next day, March 11, the bank observed problems with batch runs of collected data being processed at the affected center, in Ejby.
