US Classification:

717162, 719331

Abstract:

A runtime activation system uses a set of policies designed to provide a balance between backwards compatibility and ease of migrating existing (non side-by-side aware) applications to new runtime versions. The system chooses the runtime version to activate when an application runs or when a runtime application programming interface is invoked based on the set of policies. The system implements these policies by consulting compatibility data associated with the application indicating the intent of the author and level of side-by-side support provided by the application and/or global configuration data. Based on the compatibility data, the system chooses policies that are right in the most common cases, and easy to modify in less common cases. Thus, the runtime activation system allows applications to be flexibly configured to handle new runtime versions in a manner determined by the application author, a system administrator, or others.

International Classification:

G06F 17/30

US Classification:

707825, 707E17005, 707E1701

Abstract:

Systems and methods are described that facilitate idempotent execution of commands generated by a client for execution by a database server. Each command transmitted to the server includes a command ID generated by the client. The server attempts to execute each command and subsequently stores the command ID associated therewith in a repository along with an indication of whether the command executed successfully. When a new command is received by the server, it determines if the command ID associated therewith has already been stored in the repository. If the command ID associated with the new command has not already been stored in the repository, then the server executes the new command. If the command ID associated with the new command has already been stored in the repository and a previously-received command associated with the command ID has been executed successfully, then the server will not execute the new command.

International Classification:

G06F 15/16
G06F 17/30

US Classification:

709228

Abstract:

Systems and methods are described that establish and maintain a virtual session between a client and one or more database servers. A database server establishes a first session with a client wherein establishing the virtual session with the client comprises associating a virtual session identifier (ID) with the first session, generates state information in association with the first session, and stores the state information in a repository in association with the virtual session ID. After the first session fails, a same or different database server establishes a second session with the client wherein establishing the second session with the client comprises receiving the virtual session ID from the client, accesses the state information that was stored in the repository in association with the virtual session ID, and associates the state information with the second session.

International Classification:

G06F 11/07

Abstract:

A database server includes logic that is operable to monitor and analyze at least events occurring within an environment of the database server and/or execution errors generated by the database server in order to detect whether a problem condition exists. The database server further includes logic that is operable to send one or more commands to a database driver of a client that is communicatively connected to the database server, the one or more commands specifying one or more actions to be taken by the database driver in response to the existence of the problem condition. The database driver includes logic that is operable to receive the one or more commands from the database server and logic that is operable to cause the one or more commands to be executed.
