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.

Shared resources control in a multi-tenant system

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.
