Abstract
Aspects of the invention include techniques for providing a schema evolution on a live database system without an outage. A non-limiting example method includes initiating a schema change on a live database system. The schema change includes an attribute for a database object. A first application package having a user application that is dependent on the database object and that is bound with a release(deallocate) option is identified. Existing threads and new threads executing the first application package are routed to execute the first application package with a release(commit) option and the schema change on the live database system is completed. One or more additional threads concurrently executing one or more additional application packages remain executing with the release(deallocate) option.
