DB2 - Problembeschreibung
Problem IT02052 | Status: Geschlossen |
POOR PERFORMANCE WITH SUBSEQUENT UPDATES IN A SINGLE UOW WITH COLUMN ORGANIZED TABLES | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 | |
Problembeschreibung: | |
Performing multiple Update commands on a table within a single UOW without doing a Commit causes slow performance on the subsequent Update commands with a Column Organized (BLU) table. For example, with a 40 million row test table the initial Update will perform as expected taking 0.07 seconds. When another Update is run before a Commit then this, and any subsequent Update commands, will be significantly slower taking nearly 0.5 seconds. After running a Commit the next Update then performs as expected taking 0.07 seconds. | |
