Methods, systems, and apparatuses related to multiple instructions sets or redundant instructions for memory access and management. In one approach, a controller of the memory device provides a first set of functions for management of a storage media of the memory device. The controller uses the first set of functions to service one or more requests received from the host device. The controller provides a second set of functions for management of the storage media. The second set includes one or more functions that are redundant to the first set. When a request is received from the host device, in response to determining that the first set of functions is unavailable to service the request, the controller services the request using one or more of the redundant functions of the second set.

According to one embodiment, an information processing system is provided in which a web browser includes a re-display unit that acquires second image data based on information about an acquisition destination of a second conversion index file transmitted by a transmission unit, and displays the acquired second image data.

A method for performing security failover in an industrial production environment includes a programmable logic controller (PLC) receiving notification that a function block (FB) or a function (FC) on the programmable logic controller has been maliciously revised. The PLC next determines whether the function block or the function is also maliciously revised on a failover computing device. If the failover computing device is not maliciously revised, a failover operation is performed by the PLC. This operation includes sending a data block comprising one or more input parameters to the function block or the function and receiving an output data resulting from executing the function block or the function with the data block on the failover computing device.

Techniques are provided for using a sparse file to create a hot archive of a pluggable database of a container database. In an embodiment and while a source pluggable database is in service, a source database server creates a clone of the source pluggable database. Also while the source pluggable database is in service, the source database server creates an archive of the source pluggable database that is based on the clone. Eventually, a need arises to consume the archive. A target database server (which may also be the source database server) creates a target pluggable database based on the archive.

The present invention provides a method for accessing a flash memory module, wherein the flash memory module includes at least one flash memory chip, each flash memory chip includes a plurality of blocks, each clock includes a plurality of pages, and the method includes the steps of: providing a read-retry table, wherein the read-retry table includes a plurality of read setting levels, each read setting level corresponds to at least one read voltage, and no two read setting levels have the same read voltage; establishing a read success recording table, which records at least one specific read setting level that was previously used to successfully read the flash memory module; and when it is required to the read the flash memory module, using the at least one specific read setting level recorded in the read success recording table to read the flash memory module.

Systems, methods, and apparatuses relating to circuitry to implement lockstep of processor cores are described. In one embodiment, a hardware processor comprises a first processor core comprising a first control flow signature register and a first execution circuit, a second processor core comprising a second control flow signature register and a second execution circuit, and at least one signature circuit to perform a first state history compression operation on a first instruction that executes on the first execution circuit of the first processor core to produce a first result, store the first result in the first control flow signature register, perform a second state history compression operation on a second instruction that executes on the second execution circuit of the second processor core to produce a second result, and store the second result in the second control flow signature register.

In a data association system including: a data collection system which collects data maintained in an information system; a data storage system which stores the data collected by the data collection system; and a pipeline orchestrator which changes the frequency of update of the data stored by the data storage system, the data association system is characterized in that the pipeline orchestrator causes the data collection system and the data storage system which use a normal update path that updates the data at a specific frequency to temporarily use a high-speed update path that updates the data more frequently than does the normal update path.

The technology provides for live migration from a first cluster to a second cluster. For instance, when requests to one or more cluster control planes are received, a predetermined fraction of the received requests may be allocated to a control plane of the second cluster, while a remaining fraction of the received requests may be allocated to a control plane of the first cluster. The predetermined fraction of requests are handled using the control plane of the second cluster. While handling the predetermined fraction of requests, it is detected whether there are failures in the second cluster. Based on not detecting failures in the second cluster, the predetermined fraction of requests allocated to the control plane of the second cluster may be increased in predetermined stages until all requests are allocated to the control plane of the second cluster.

A method for allocating memory in a computing device having a non-volatile main memory is described. The method comprises receiving, by a memory allocator, a request for non-volatile memory allocation of an object from a program executing on the computing device, the request comprising a requested memory size and registration data from the program. The method comprises finding an available address of one of a plurality of portions of a page of the non-volatile memory and searching an active page table in the non-volatile main memory to find the page and if the page is not found in the active page table: inserting the page into the active page table; and waiting for a memory write for inserting the page into the active page table to complete.

Examples may represent update results of installation of firmware updates of a firmware bundle on a hardware resource. Examples include determining, from an update result, whether the installation of a firmware update on a component of the hardware resource is failed or succeeded to identify a failed component or a successful component, and representing the failed component or the successful component.
