UPGRADE TO DB2 9.7 CAN REQUIRE AN UNEXPECTEDLY LONG TIME FOR INDEX REBUILD | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 910 - DB2 | |
Problembeschreibung: | |
In DB2 9.7 new meta data has been added to all index root pages. During database upgrade we check if there is enough space to upgrade the root page page and if there is not, then we mark the entire index object as invalid and the index will be rebuilt after database upgrade. Index rebuild can take several hours and will acquire and hold a Z lock on the table for the entire duration of the index rebuild. This can leave the database unusable for several hours after the upgrade. This change adds a new service option to the db2dart tool in 9.1 so that a customer may determine which indexes will need to be rebuilt after database upgrade to DB2 9.7. The new code will execute when db2dart is run with both the "/ico y" and "/serv 16" options. Note: This requires using the service password. Usage: db2dart <dbName> /ico y /serv 16 /scr m /pw <servicePassword> The "/ico y /serv 16" can also be used with actions /DB (the default) or /T or /TS. | |
