API privileges for the container group are revoked, using the HA, from the GA. The container group is dropped using the HA.

Abstract: A method for managing location-aware reminders in an automobile includes monitoring a geographic location of the automobile using a computer system installed in the vehicle. The computer system detects that the automobile has entered a geographic region associated with a location-aware reminder and issues a reminder message associated with the location-aware reminder to a driver of the automobile based on the detecting.

Abstract: According to some aspects, a system for detecting a designated wake-up word is provided, the system comprising a plurality of microphones to detect acoustic information from a physical space having a plurality of acoustic zones, at least one processor configured to receive a first acoustic signal representing the acoustic information received by the plurality of microphones, process the first acoustic signal to identify content of the first acoustic signal originating from each of the plurality of acoustic zones, provide a plurality of second acoustic signals, each of the plurality of second acoustic signals substantially corresponding to the content identified as originating from a respective one of the plurality of acoustic zones, and performing automatic speech recognition on each of the plurality of second acoustic signals to determine whether the designated wake-up word was spoken.

Abstract: Systems and methods are disclosed for connection multiplexing in a parallel processing environment. An example method includes requesting, responsive to a request to perform multiple database operations in a single transaction, a connection identifier for a physical connection to the database, providing the connection identifier to each of a plurality of workers, and performing the multiple database operations using the plurality of workers. Each worker may obtain a work item from a work queue, initiate a database request for the work item, and provide the database request to a database server. The database request represents one of the multiple database operations and includes the connection identifier. The database server may determine that the connection identifier corresponds to the physical connection, add the request to a connection queue associated with the physical connection, and execute requests from the connection queue against the database via the physical connection.

Abstract: Parameter-based deployment control for database objects is provided, in which processes for deploying database artifacts into a database as database objects are implemented. Many different techniques may be used in executing such deployment processes, including whether and how to combine various deployment-related jobs, identify/record/assess/correct potential errors, govern or instruct artifact conversion operations, or generally manage available resources with respect to executing the deployment(s) efficiently. By providing for selectable parameter values that are executed in an efficient, e.g., hierarchical, manner, deployment procedures may be implemented in a highly efficient and customizable manner.

Abstract: A computer-implemented method for exporting a database container from a database includes exporting database container metadata including artifact definitions in the metadata along with the actual metadata content to a database management system, exporting the database container including the database objects deployed therein to the database management system. The exporting of the database container includes exporting dependencies and structures of the database objects deployed therein, but not the actual content of the database objects. In some instances, however, exporting of the database container can include exporting the actual content of the database objects in response to user request. The method further includes packing the exported database container metadata and the exported database container in an archive. The data in the archive can be unpacked in substantially reverse order to import the database container into another database.

Abstract: In an example embodiment, a new development infrastructure is provided that provides an external repository for database definitions. The development infrastructure also then includes a development mode. When using the development mode, the behavior of the development infrastructure is modified to better fit the development of database artifacts. The developer uses a development base version of a definition (usually the latest released version of the definition) but also creates migrations that indicate how the development base version should be modified to arrive at the developer's intended new definition. While still in development mode, the deployment may be run, which causes data in the development mode that uses the old definition to be dropped and replaced by the base version. The development mode then executes the specified migrations.

Abstract: Systems and methods are disclosed for automatically detecting a connection status in an asynchronous processing request. An example method includes obtaining, at a processing client and responsive to a first request from a requesting client to perform a plurality of database operations in a single transaction, a connection identifier for a connection to a database on a database server, the connection to be used to execute the plurality database operations and storing the connection identifier in a row of a status table. In some implementations the existence of the row indicates the status of the connection is active. In some implementations the row includes a flag indicating the status. The method also includes providing the connection identifier to the requesting client, receiving a second request from the requesting client, the second request being for a status of the connection, determining the status using the status table.

Abstract: A computer-implemented method for deploying a new artifact file in a database. The new artifact file provides specifications for one or more new run-time database objects to be created in the database by processing of the new artifact file by artifact-type specific conversion engines. The method includes assigning ownership of the one or more new run-time database objects to be created in the database to the new artifact file, and, when an existing database object in the database provided by another artifact file corresponds to a new run-time database object specified in the new artifact file, assigning ownership of the existing database object in the database to the new artifact file being deployed.

Abstract: Embodiments map from a database environment, dependencies between files created at designtime and corresponding runtime data objects defined by deployment of those files. A dependency table is populated with dependency information (e.g., origin, target, dependency type) extracted during deployment. That dependency information may be searched according to user-specified parameters (e.g., a file provides an object; an object requires a file), to allow rapid correlation between designtime file(s) and related runtime data object(s). Embodiments are particularly useful in visualizing complex (e.g., one-to-many; many-to-one) file-object dependencies characteristic of modern database environments. Queries posed to the dependency table may further seek intra-designtime dependency information (e.g., one file depends upon another file; one file impacts another file), and/or intra-runtime dependency information (e.g., table objects referenced by view objects; view objects referenced by procedure objects).

Abstract: Whether database objects corresponding to an artifact to deploy already exists in a database is determined. Depending artifacts are calculated using a prior-generated dependency graph. Whether any database objects corresponding to the calculated depending artifacts need to be redeployed are determined. Whether a build plugin corresponding to the database objects needing to be redeployed supports a redeployment option is determined. The artifacts are processed according to an execution graph.

Abstract: An external database schema permitted to be accessed from a container using a database synonym is determined. A logical schema representing the external database schema is defined. A synonym for the container is defined using the logical schema and an object associated with the external database schema. The logical schema and synonym is deployed to the container using a logical schema plugin. The container is configured to disable the logical schema plugin and to only allow references to the defined logical schemas.
