Abstract: A computer implemented method for monitoring databases includes providing views for monitoring information associated with a first datacenter and proxy views for monitoring information associated with a second datacenter. The first datacenter receives a query for monitoring information associated with services running on the first datacenter and/or the second datacenter. The first datacenter parses the query to identify filter information that identifies which of the first or second datacenter the requested services are running on. If the filter information indicates the service is running on the first datacenter, the first datacenter queries the views to request the monitoring information from the server on the first datacenter running the requested service.

Abstract: A computer implemented method is provided comprising receiving a group of transaction logs from a first database, allocating transaction logs from the group of transaction logs to a first queue and to a second queue, generating an end-of-group transaction log indicative of an end of the group of transaction logs, allocating the end-of-group log to the first queue and the second queue; replaying transaction logs from the first queue including the end-of-group transaction log allocated to the first queue, replaying transaction logs from the second queue including the end-of-group transaction log allocated to the second queue; and changing visibility of one or more transactions in response to replaying the end-of-group transaction log allocated to the first queue and the end-of-group transaction log allocated to the second queue. Related apparatus, systems, techniques and articles are also described.

Abstract: A computer implemented method for replication includes registering a first database system with a second database system and performing a failback operation on the first database system. The failback operation includes opening a snapshot that includes data known to have existed on the first database system and the second database system at a first time. Transaction log information is requested from the second database system. The transaction log information corresponds to transactions performed on the second database system beginning with the first time. The transaction log information is applied to the snapshot data on the first database system. Related apparatus, systems, techniques and articles are also described.

Abstract: A new query language can be embedded in a business application programming language (e.g., the ABAP language). A query language consistent with implementations of the current subject matter can be based on a graph data-model of connected business objects (BO) or other data objects and can be designed as an efficient query language embedded into the business application programming language runtime, thereby allowing expression of business logic in a declarative manner.

Abstract: Methods and apparatus, including computer program products, are provided for implementing a cooperative model between an application and a database. In one aspect, there is provided a computer-implemented method. The method may include receiving from an application a command to perform an operation at a database; accessing metadata representative of the application; configuring, based on at least the metadata, a result of the operation; and sending the configured result to shared memory accessible by the application. Related apparatus, systems, methods, and articles are also described.
