Problem IT25281 | Status: Closed |
SLOW INSERT PERFORMANCE WHEN USING MON_OBJ_METRICS EXTENDED | |
product: | |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 | |
Problem description: | |
Using DB CFG parameter MON_OBJ_METRICS = EXTENDED can lead to increased section close times impacting insert/update/delete performance when there exist many table partitions. A timed Db2 trace shows quite long gap between sqlricls_complex data [probe 1980] and [probe 2145], e.g.: 0.000877621 | | | sqlricls_complex entry [eduid 48658 eduname db2agent] 0.000878900 | | | sqlricls_complex data [probe 1980] 0.006305744 | | | sqlricls_complex data [probe 2145] 0.006378330 | | | sqlricls_complex exit | |
