Abstract

The present disclosure teaches solutions for patching content in database systems. In one example, a deployment package for an upgrade of a database system to a new system is received, and the content is deployed to a shared container. Shared objects are identified that are completely stored in the shared container, and partially-shared objects are identified where those objects have a shared portion in the shared container and a tenant portion in one or more tenant containers. First shared content is determined for the shared objects, while second shared content is determined for partially-shared objects. The first and second shared content is then deployed to the shared container. Local content is determined for the partially-shared objects and is deployed to each tenant container. Local content is then identified for local objects and is also deployed to each respective tenant container. Accordingly, both shared and tenant content is deployed.
