Abstract: Methods, systems, and other embodiments for protecting a shared resource in a data processing system are described herein. In one embodiment, when responding to a request that requires use of the shared resource, determine whether a previously established sleep period for the shared resource has expired. If so, determine a health status of the shared resource based on one or more of applying an asymptotic transform to a percentage of time that a processing unit is idle and applying a linear transform to a session count for the shared resource. Then, determine whether the health status is sufficient to permit responding to the request; and if not, (i) determining an appropriate sleep period for the shared resource, (ii) initiating a sleep state for the shared resource for a period substantially equal to the determined appropriate sleep period; and (iii) exiting the sleep state and responding to the request.

Abstract: Systems, apparatuses, and methods for preventing the use of a shared resource (such as a database) by a user or group of users from causing other users to experience unsatisfactory or unreliable access to that resource or to related, impacted resources (such as a communications network or processor). In some embodiments, the invention is directed to systems, apparatuses, and methods that may be implemented in a multi-tenant system in order to prevent a single user or the users associated with an account from degrading the system performance experienced by other users, either by intentional or inadvertant misuse of a shared database, and to prevent an overload condition from causing the system or database to fail abruptly.

Abstract: A system, apparatuses, and methods for enabling a third party application installed on a multi-tenant platform to utilize an external service, where that service requires a user to provide authentication credentials, without exposing those credentials to the third party application. The invention enables an extension of the platform's services, applications, and functionality via the use of the third party application and the external service, but without the risk that the application might expose the credentials to misuse or otherwise cause a breach of the security measures applicable to the data and/or services of a tenant, a tenant's users, or the platform itself.
