Virtual machine optimization and / or storage reclamation solutions are disclosed that manage virtual machine sprawl and / or growing enterprise storage costs. For instance, certain solutions receive recommendations based on one or more rules, policies and / or user preferences that identify storage and / or alignment criteria for virtual machine disk (VMDK) partition(s). In certain examples, a resize tool that operates within a host operating system of a host server dynamically resizes and / or aligns one or more VMDK partitions of a powered-down virtual machine. For instance, the resize tool can be injected to the host server from a remote management server and can resize and / or align the VMDK partitions without requiring contents of the VMDK to be copied to another VMDK. By reallocating storage and / or aligning the VMDK partitions, embodiments of the invention can increase virtual machine performance and improve storage management.

A method of revoking a descrambling privilege for copy controlled content to a host device is provided. The method includes receiving copy controlled content at a conditional access module. A revocation list is also received at the module. The method includes determining whether the host device associated with the module is on the list. If so, the conditional access module will not descramble the content.

Techniques for migrating data in a database include identifying an update to one or more data entries of a source table; determining that a status of a trigger associated with the source table indicates to update a logging table, and in response: updating, in a first transaction, (i) the one or more data entries of the source table, and (ii) one or more data entries of the logging table based on the user input, and copying content of the source table to a target table; and determining that the status indicates to update the target table, and in response: updating, in a second transaction, (i) the one or more data entries of the source table and (ii) one or more data entries of the target table based on the user input, and updating the content of the target table based on the one or more data entries of the logging table.

A move engine and operating system transparently reconfigure physical memory to accomplish addition, subtraction, or replacement of a memory module. The operating system stores FROM and TO real addresses in unique fields in memory that are used to virtualize the physical address of the memory module being reconfigured and provide the reconfiguration in real-time through the use of hardware functionality and not software. Using the FROM and TO real addresses to select a source and a target, the move engine copies the contents of the memory module to be removed or reconfigured into the remaining or inserted memory module. Then, the real address associated with the reconfigured memory module is re-assigned to the memory module receiving the copied contents, thereby creating a virtualized physical mapping from the addressable real address space being utilized by the operating system into a virtual physical address space.

A processor contains a move engine and mapping engine that transparently reconfigure physical memory to accomplish addition, subtraction, or replacement of a memory module. A mapping engine register stores FROM and TO real addresses that enable the engines to virtualize the physical address of the memory module being reconfigured and provide the reconfiguration in real-time through the use of hardware functionality and not software. Using the FROM and TO real addresses to select a source and a target, the move engine copies the contents of the memory module to be removed or reconfigured into the remaining or inserted memory module. Then, the real address associated with the reconfigured memory module is re-assigned to the memory module receiving the copied contents, thereby creating a virtualized physical mapping from the addressable real address space being utilized by the operating system into a virtual physical address space. During the process of moving the memory contents, the mapping engine maps Write memory requests addressed to the real address space currently associated with the reconfigured memory module to both the FROM and TO real address space. As will be appreciated, a memory module can be inserted, removed or replaced in physical memory without the operating system having to direct and control the reconfiguration of physical memory to accomplish the physical memory change.

A computer system for generating a dynamic presentation comprises:a master storage containing master presentation data having a master nodal structure and master contents associated with content nodes of said structure,a structure editor capable of copying said master nodal structure into a personalized data structure in a dedicated read / write storage and of selectively changing the copied master nodal structure into a personalized nodal structure in response to user inputs, wherein said personalized nodal structure comprises all or part of the nodes of the master nodal structure,a contents editor capable of copying a master content into said personalized data structure in said dedicated read / write storage and of selectively changing the copied master content into a personalized content in response to user inputs,a dynamic presentation generator for generating a personalized presentation by accessing said personalized data structure, determining which content nodes in said structure belong to personalized presentation, and for any such content node selectively accessing master contents or personalized content if the latter is present in said personalized data structure.

Exemplary embodiments of the present invention relate to methodologies, computer program products and systems for the support of content replication, wherein transaction-level data replication consistency is guaranteed. Further, the exemplary methodologies of the present invention can be implemented while incurring little or no additional I / O overhead.
