About Product Improvement Program
To prioritize enhancements in future releases, SQL Optimizer for DB2 z/OS collects data about the use of its different features, and periodically, this data is communicated back to us. Initially, this usage data includes an IP address. Upon its receipt at a temporary server in the U.S.A., the IP address is removed, and then the anonymous data is aggregated before it is sent to our servers in California. Our product team analyses the aggregated data to understand our user community’s preferences and common practices. This analysis influences our future releases.
