TIMESTAMPS MAY NOT REFLECT DAYLIGHT SAVINGS TIME CHANGES IN CERTAIN SITUATIONS | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 | |
Problembeschreibung: | |
In DB2 pureScale environments certain timestamps used by DB2 may not accurately reflect the current "daylight savings time" (aka "Summer Time") status if the DB2 member has been up during a daylight savings time change. Not all timestamps are affected, which can in certain scenarios lead to errors. For example, if a DB2 pureScale instance is started in mid-October and left running through to the end of North American Daylights Savings Time (currently the first weekend in November), certain timestamps used by DB2 will still be calculated as if Daylight Savings Time is in effect, causing them to be an hour ahead of the correct value. In certain scenarios this can lead to objects that appear to have been created in the future, leading to errors if an attempt to alter the object is made before the "create" time has passed (in other words, within an hour of object creation). This can manifest in several ways, including SQL0204 errors when accessing objects with incorrect creation times. | |

Local-Fix: | |
When Daylight Savings Time has begun (Spring) or ended (Fall), individual DB2 pureScale members should be stopped and restarted. After restart the member will return correct timestamps. Once all members have been restarted the instance is not exposed to this issue until the next Daylight Savings Time change. Member restarts can be staggered so that overall availability is not impacted. | |
