Abstract

Methods, computer program products, and systems are presented. The methods include, for instance: collecting real time system statistics on a system environment in a remote platform running a remote data source amongst a plurality of remote data sources of a virtual database. Real time data source statistics on one or more data source objects from the remote data source of the virtual database is also gathered. A global catalog of the virtual database is updated with the real time system statistics and the real time data source statistics. An access plan to process a query to the virtual database is optimized based on the real time system statistics and the real time data source statistics and a response is produced based on the access plan, with improved performance and reduced cost.
