摘要： A method and system for improving memory access patterns of software systems on NUMA systems discovers NUMA system resources, where the NUMA system resources comprises a plurality of NUMA nodes; determines a plurality of database threads, processes, and objects for a database configuration; and generates a policy which assigns the plurality of database threads, processes, and objects to the plurality of NUMA nodes, wherein the generating is performed prior to initialization of the plurality of database threads, processes, and objects. The assignment of the database threads, processes, or objects to NUMA nodes is such that the amount of remote memory accesses is reduced. When the database thread, process, or object initializes, the database server queries the policy for its assigned NUMA node(s). The database thread, process, or object is then bound to the assigned NUMA node(s). In this manner, the costs from remote memory accesses are significantly reduced.

摘要： Provided are a method, system, and program for handling access requests to a page while copying an updated page of data to storage. An update to a page in a memory is received and indication is made that the page has an exclusive lock. The update is applied to the page and an operation is initiated to copy the updated page to a physical log in a storage in response to applying the update to the page. Reads and writes are allowed to proceed against the page while the operation to copy the updated page to the physical log in the storage is occurring.

摘要： A computer system dynamically scales back latch requests for system resources. Tasks seeking access to system resources each dynamically determine the probability that the task will gain access to the latch relating to a given system resource. Where the task estimates that its probability is below a defined threshold, the task will suspend itself for a defined sleep time. The task dynamically adjusts the length of the sleep time based on the number of times the task enters the suspended state and on the relative changes in the estimated probability that the task will gain access to the resource.

摘要： For an information retrieval system coupled to a buffer pool maintaining a plurality of pages of recently accessed information for subsequent re-access, a technique for starting the buffer pool is provided. The technique facilitates a quicker start to the buffer pool by deferring allocation of page storing portions, for example, until they are needed. The technique makes the buffer pool available for storing pages while deferring allocation of a page storing portion of the buffer pool and allocates the page storing portion of the buffer pool in response to a demand to store pages to the buffer pool. The technique may be used to re-start a buffer pool with pages stored to a memory coupled to the information retrieval system where the pages where stored upon a buffer pool shutdown. Further, buffer pool readers or prefetchers may be configured to read pages for storing to the buffer pool and allocate the page storing portions of the buffer pool in response to instructions to read particular pages.

摘要： A method, computer program product and database management system for recording a change to a database in a log including a plurality of log records. The database management system is capable of concurrently processing and logging multiple database changes. A tracking descriptor is used in conjunction with first and second identifiers for each log record to reduce the amount of logic executed using latching for each log record.

摘要： A system and an associated method selectively process log files for enhancing performance of tablespace recovery by processing only those log files required, and for selecting which log file to process during recovery for both redo and rollback phases of recovery. The system and method skip the processing of log files that do not contain records of interest for the tablespace being recovered and determines whether a log file contains anything that needs to be played, in particular for the recovery of a subsystem in the database, such as a tablespace. Pre processing of the log files is not done, rather including tablespace ID correlated with log file ID information is collected while the log files are created. The cross-correlated information is used during tablespace recovery to selectively determine which of the log files to process. Some log files may be skipped in cases where not all of the database system is being recovered. A sub set of the database can be recovered, such as a tablespace, and which log files to process is determined based on a lock instruction.
摘要翻译：系统和相关方法通过仅处理所需的日志文件，并选择在恢复期间进行恢复时要处理的日志文件来选择性地处理日志文件以增强表空间恢复的性能。系统和方法跳过不包含要恢复的表空间的感兴趣记录的日志文件的处理，并确定日志文件是否包含任何需要播放的内容，特别是用于恢复数据库中的子系统，例如一个表空间。日志文件的预处理未完成，而在创建日志文件时收集与日志文件ID信息相关的表空间ID。在表空间恢复期间使用交叉相关信息来选择性地确定要处理哪些日志文件。在没有全部数据库系统正在恢复的情况下，可能会跳过某些日志文件。可以恢复数据库的子集，例如表空间，以及基于锁定指令确定要处理哪些日志文件。

摘要： An adaptive throttling system for minimizing the impact of non-production work on production work in a computer system is provided. The adaptive throttling system throttles production work and non-production work to optimize production. The adaptive throttling system allows system administrators to specify a quantified limit on the performance impact of non-production or utility work on production work. The throttling rate of the utility is then automatically determined by a supervisory agent, so that the utilities' impact is kept within the specified limit. The adaptive throttling system adapts dynamically to changes in workloads so as to ensure that valuable system resources are well utilized and utility work is not delayed unnecessarily.

摘要： Regulating the execution of software execution units to manage the performance impact of administrative utilities is disclosed. Administrative utilities (e.g., filesystem and database backups, garbage collection in the Java Virtual Machines, etc.) are an essential part of the operation of production systems. Performance impact is managed through the use of throttling, either external or internal, which forces utilities to slow down their processing by a configurable amount. While a variety of criteria may be used for throttling, a self-induced sleep in preferred for internal throttling.
