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.

Abstract: The disclosure generally describes methods, software, and systems, including a method for updating an application. At least one application instance of an application is managed. Each application instance is associated with a plurality of executing work processes connected with a first database schema. A bridge database schema is generated that is related to the first database schema. The bridge database schema represents a copy of the first database schema and is generated in response to initiation of an update to the application. In response to determining that the generation of the bridge database schema is complete, for each of the plurality of work processes, a commit work action performed by the particular work process is determined. In response to determining performance of the commit work action, the particular work process is connected to the bridge database schema.

Abstract: The present disclosure involves systems, software, and computer implemented methods for patching content in database systems. One example method includes receiving a deployment package for an upgrade of a database system to a new version. Content is deployed to a shared container. Shared objects are identified that are completely stored in the shared container. First shared content is determined for shared objects. Partially-shared objects are identified that have a shared portion in the shared container and a tenant portion in one or more tenant containers. Second shared content is determined for partially-shared objects. The first shared and second shared content are deployed to the shared container. Local content is determined for the partially-shared objects and deployed to each tenant container. Local objects that have no data in the shared container are identified. Local content is identified for the local objects and deployed to each respective tenant container.

Abstract: A zero downtime upgrade procedure is initiated that upgrades a first version of software executing on a source system comprising at least one source server to a second version of software executing on a target system comprising at least one target server. The source system initially starts operating in a read-write mode. Thereafter, concurrent with the operation of the source system, operation of the target system is initiated in a read-only mode. Operations of the source system are then ceased by ramping down activities of the source system. Upon cessation of operation of the source system, operation of the target system is initiated in a read-write mode.

Abstract: A system and method for database migration is provided. In an example embodiment, the database migration technique may include execution modules having a first connection to a source database and a second connection to a target database, and orchestration modules adapted to identify first and second subsets of statements from a single storage table, wherein the first and second subsets of statements are executed by the execution modules during an uptime period of the source database.
