DB2 - Problem description
Problem IC89219 | Status: Closed |
ASYNCHRONOUS RUNSTATS REQUESTS MIGHT BE LOST IN DPF ENVIRONMENTS FOR TABLES THAT DO NOT RESIDE ON THE CATALOG DATABASE PARTITION | |
product: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problem description: | |
When the real time statistics (RTS) feature is enabled for a database, db2agent EDUs compiling SQL statements can synchronously collect statistics and make asynchronous runstats requests to be satisfied by the background RTS daemon. The asynchronous requests might be lost in DPF environments for tables that do not reside on the catalog database partition. Whether the problem will occur is not deterministic. If the problem occurs, until statistics are refreshed by a subsequent synchronous or asynchronous collection, the query optimizer will have less accurate statistics when making access plan decisions. | |
