摘要： Techniques are provided for managing, within a storage system, the sequence in which I/O requests are processed by the storage system based, at least in part, on one or more logical characteristics of the I/O requests. The logical characteristics may include, for example, the identity of the user for whom the I/O request was submitted, the service that submitted the I/O request, the database targeted by the I/O request, an indication of a consumer group to which the I/O request maps, the reason why the I/O request was issued, a priority category of the I/O request, etc. Techniques are also provided for automatically establishing a scheduling policy within a storage system, and for dynamically changing the scheduling policy in response to changes in workload.
摘要翻译：提供了技术，用于至少部分地基于I / O请求的一个或多个逻辑特性在存储系统内管理由存储系统处理I / O请求的序列。逻辑特征可以包括例如提交I / O请求的用户的身份，提交I / O请求的服务，I / O请求所针对的数据库，消费者组的指示 I / O请求映射到哪里，发出I / O请求的原因，I / O请求的优先类别等。还提供了用于在存储系统内自动建立调度策略，并且为了动态地根据工作负载的变化改变调度策略。

摘要： A method, system, and computer program product for cost based analysis for data access in a database management system. In one approach, the method, system, and computer program product identifies data to access. A first cost for direct I/O storage access and a second cost for cache access are then determined for accessing the data. A comparison between the first cost and the second cost is then performed. Finally, a first portion of identified data is accessed based at least in part upon the comparison.

摘要： An approach for providing efficient network data transfer service is provided. In one embodiment, a first database server receives, from a second database server, a first request to access a first storage subsystem. Here, the second database server cannot access first data in the first storage subsystem without another database server transmitting the first data to the second database server. In response, the first database server provides the second database server a first set of access primitives. Using the first set of access primitives, the second database server may access data stored in the first storage subsystem that may be otherwise not accessible. As a result, the first database server receives, from the second database server, a first data access request to access first data stored in the first storage subsystem.

摘要： Techniques for the centralized storage and management of parameters for databases are provided. Configuration parameters for instances of a database server can be stored centrally and associated with the appropriate instance. Additionally, configuration parameters that are modified during run time of the instance can be stored so that subsequent instances can be initialized using those configuration parameters, which can result in new instances that are tuned for the environment.
摘要翻译：提供了数据库参数集中存储和管理技术。可以集中存储数据库服务器实例的配置参数，并与适当的实例相关联。此外，可以存储在实例的运行时间期间修改的配置参数，以便可以使用这些配置参数初始化后续实例，这些配置参数可能会导致为环境调整的新实例。

摘要： A computer-implemented method of implementing a network file system may include steps of providing a host, the host including an Operating System (OS) that includes a kernel and a first client implementing the Network File System (NFS) protocol in the kernel, and a database server process. A second NFS client may be provided in the database server process. A NFS server may be provided, coupled to the host. A device implementing the Network Attached Storage (NAS) protocol may also be provided, coupled to the NFS server. NFS requests to access data stored in the NAS server may then be generated and sent from the second NFS client in the database server process directly to the NFS server, bypassing the first NFS client in the OS kernel of the host. NFS File handles obtained by one database process may be shared with other database processes through a shared memory area.
