Under the present invention, a history of requests for data objects are tracked and maintained in a cache log. Based on the history, certain data objects are prefetched into a cache. When a request for a cached data object is later received, the requested data object can be retrieved from the cache and served to the requesting user. Thus, the latency involved with obtaining the data objects from the appropriate sources is eliminated. Further, under the present invention, discard and refresh rules are assigned to each data object on a class basis. Accordingly, data objects in the cache can be refreshed and/or discarded so that the caching operation can be optimized.

Summary information for documents are stored as entries in a table in a relational database. Each entry includes a unique identifier, value(s) for a set of attributes and rendering information for the corresponding document. A collation order is obtained that defines a sort order for the documents based on the set of attributes. An index is generated based on the collation order and includes the rendering information for each document. In response to a rendering request or other query, a query that uses index-only access for the summary table can be used to obtain the rendering information. Further, a set of marker values can be included to provide efficient navigation of the index. Still further, additional functionality can be included to display the documents in a hierarchical structure. To this extent, the invention can automatically re-categorize data when the child locations of a hierarchical location exceed a specified number and/or link other relational data to a hierarchical location.

A system that persistently maintains and exposes one or more previous object hierarchies to which an object belonged across one or more hierarchy destroying operations, such as operations that delete parent objects, add parent objects subsequent to addition of their descendent objects, forward objects to or from the hierarchy, and/or modify hierarchy determining rules. A user interface object allows user access to one or more persistent hierarchies for the corresponding object. A hierarchy list or the like allows a user to select a desired one of the persistent hierarchies. A persistent hierarchy can be accessed in the disclosed system through a display object associated with any object within the hierarchy, including the root, leaves, and any intervening objects. When objects are deleted, “ghost” objects are maintained and displayed to the user in the hierarchical positions of the deleted objects when a persistent hierarchy is displayed.

A piston for an internal combustion engine having a double tapered top land to provide controlled variation in the clearance about the head of the piston. The controlled variation in clearance about the piston head provides a sufficiently sized orifice which prevents the formation of hard carbon and improves oil control without greatly increasing pollutants.

A system selectively provides a selected program, such as a movie, to viewers who select the program by pushing a button as an attachment to a television set. The selected program is carried on a standard television channel unused in the area for regular programming having a carrier frequency f. sub. c. This signal is mixed with the second harmonic of the master oscillator at the input of the master antenna TV system to translate the selected program channel to a midband channel between the standard high and low VHF television bands. The master oscillator signal is also injected into the input of the MATV system and used for providing remote control of the room box and as an input to a frequency converter which converts the midband channel back to the standard TV channel when the user presses the selector button on the room box. A command carried by the master oscillator signal produces a pulsed radio frequency signal having a width that signifies the state of the room box in a time slot indicating the room in which the box is located.

Denial-of-service attacks are prevented or mitigated in a cloud compute environment, such as a multi-tenant, collaborative SaaS system. This is achieved by providing a mechanism by which characterization of “legitimate” behavior is defined for tenant applications or application classes, preferably along with actions to be taken in the event a request to execute an application is anticipated to exceed defined workflow limits. A set of application profiles are generated. Typically, a profile comprises information, such as a request defined by one or more request variables, one or more “constraints,” one or more “request mappings,” and one or more “actions.” A constraint is a maximum permitted workload for the application. A request mapping maps a request variable to the constraint, either directly or indirectly. The profile information defines how a request is mapped to a workload to determine whether the request is in policy or, if not, what action to take.
