Abstract: Several methods and a system of a workload management of a concurrently accessed database server are disclosed. In one embodiment, a method includes applying a weight to a service class. The method also includes generating a priority of the service class. In addition, the method includes selecting a group based on the weight of the service class. The method further includes determining a priority level based on the priority of the service class. The method also includes generating a characteristic of a shadow process through the weight and the priority of the service class. In addition, the method includes executing a query.

Abstract: Several methods and a system of a replicated service for write ahead logs are disclosed. In one embodiment, a method includes persisting a state of a distributed system through a write ahead log (WAL) interface. The method also includes maintaining a set of replicas of a WAL through a consensus protocol. In addition, the method includes providing a set of mechanisms for at least one of detection and a recovery from a hardware failure. The method further includes recovering a persistent state of a set of applications. In addition, the method includes maintaining the persistent state across a set of nodes through the hardware failover. In one embodiment, the system may include a WAL interface to persist a state of a distributed system. The system may also include a WAL replication servlet to maintain and/or recover a set of replicas of a WAL.

Abstract: A computer-implemented system and method for providing a legitimacy rating of a content source are provided. A request for a document is received. An electronic document associated with a content source is passed by a document provider in response to the request. A legitimacy rating of the content source is passed. Examples of legitimacy rating information include, for example, a history rating of the content source based on the length of time the document provider has published documents associated with the content source and a transaction volume rating of the content source based on the number of electronic documents associated with the content source that are passed by the document provider.
