摘要： Examples of techniques for sensitive data redaction in a memory dump are described herein. An aspect includes, based on a dump of a virtual address space being triggered, receiving a primary dump corresponding to the virtual address space, the primary dump including one or more tagged memory pages. Another aspect includes identifying, by a sensitive data identification module, sensitive data that is located outside of the of the one or more tagged memory pages in the primary dump. Another aspect includes redacting data corresponding to the sensitive data and the one or more tagged memory pages to determine a redacted dump.

摘要： A shared cache line is concurrently modified by multiple processors of a computing environment. The concurrent modification is performed based, at least, on receiving one or more architected instructions (Fetch due to Non-Coherent Store instructions) that permit multiple processors to concurrently update the shared cache line absent obtaining a lock or having exclusive ownership of the data.

摘要： A single architected instruction is obtained to perform multiple functions. The instruction is executed, and the executing includes performing a first function of the multiple functions and a second function of the multiple functions. The first function includes moving a block of data from one location to another location, and the second function includes setting a storage key. The storage key is associated with the block of data at the other location and controls access to the block of data. The first function and the second function are performed as part of the single architected instruction.

摘要： In one embodiment, a computer-implemented method includes building an available frame header queue (AFHQ). The AFHQ includes one or more headers, each header including one or more frame references being no more than a maximum count of frame references. Each of the one or more frame references of each of the one or more headers refers to an available frame. A frame request is received for one or more requested frames. One or more frame references are extracted, by a computer processor, from the AFHQ in response to the frame request. The extracting includes extracting from the AFHQ one or more requested headers including the one or more frame references referring to at least a portion of the one or more requested frames.

摘要： Embodiments of the present invention provide systems and methods for clearing specified blocks of main storage. In one embodiment, an EADM start subchannel is executed. The instructions of the execution of the EADM start subchannel may include a SAP receiving an ADM request block, which specifies a main-storage-clearing operation command. The address and size of a block of main memory to be cleared by the SAP is specified in an MSB designated by the ADM request block.

摘要： A memory system is configured for access by a plurality of computer processing units. An address lock bit is configured in a translation table of the memory system. The address lock supports both address lock shared and address lock exclusive functions. A storage manager of an operating system configured to obtain exclusive access to an entry in a DAT table either by obtaining an address space lock exclusive or obtaining an address space lock shared, and setting a lock bit in a DAT entry.

摘要： A method for obtaining and storing monitoring information. The method includes one or more computer processors generating a plurality of data records, based at least in part on a configuration for generating information, wherein the plurality of data records includes a first data record. The method further includes determining that a configuration for analyzing information dictates an analysis of at least a one data record, wherein the at least one data record includes a second data record. The method further includes determining that the plurality of data records do not include the second data record. The method further includes modifying the configuration for generating information to include generating the second data record. The method further includes generating an updated plurality of data records based on the modified configuration for generating information, wherein the updated plurality of data records includes the first data record and the second data record.

摘要： A method, a computer program product, and a system for performing a batch processing are provided. The batch processing includes initializing a set of elements corresponding to a set of resources to produce an initialized group and chaining the initialized group to previously initialized elements to produce an element batch, when the previously initialized elements are available. The batch processing further includes setting a system lock on the set of resources after the element batch is produced; executing a service routine to move the element batch to a queue by referencing first and last elements of the element batch; and releasing the system lock on the set of resources once the service routine is complete.
