HIGH SYSTEM CPU DURING ONLINE BACKUP DUE TO LARGE NUMBER OF DB2BM THREADS | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
Running an online backup may cause very high system cpu usage on the system. This is caused by the number of db2bm threads created compared to the number of db2med threads actually writing out the data to the backup location. This APAR addresses a change to the autonomic tuning algorithm to prevent the creation of an excessive number of db2bm threads. | |
