摘要： A method and apparatus for loading an XML document into memory is provided. A client loads one or more array elements into a first partition of an array that is maintained in memory. Each array element represents an XML element of an XML document. Upon determining that an amount of data maintained in the first partition exceeds a first threshold, the client subsequently loads array elements into a new partition of the array. Upon determining that an amount of data maintained in the memory of the client exceeds a second threshold, the array elements of the least recently used partition are persistently stored in a database without persistently storing the entire XML document. When the last XML element of the XML document is loaded into a partition of the array, that partition is persistently stored in the database, thereby causing the entire XML document to be stored in the database.

摘要： A method and apparatus for processing a file system operation at a database server is provided. A request to perform a file system operation on a resource stored in a database is received at a database system. The request may be implemented using the NFS protocol. The request may include state identification data that identifies state information associated with the request. State information associated with the request is retrieved within the database system based on the state identification data. State information is information that describes the operational state of the requestor for a particular file. The request is then processed based, at least in part, on the state identification. File system operations may be processed a database management system to access any data, such as a file, relational data, and object-relational data.
摘要翻译：提供了一种在数据库服务器处理文件系统操作的方法和装置。在数据库系统中接收对存储在数据库中的资源执行文件系统操作的请求。请求可以使用NFS协议实现。该请求可以包括标识与请求相关联的状态信息的状态标识数据。基于状态识别数据在数据库系统内检索与请求相关联的状态信息。状态信息是描述特定文件的请求者的操作状态的信息。然后，至少部分地基于状态标识处理该请求。可以处理文件系统操作数据库管理系统以访问任何数据，例如文件，关系数据和对象关系数据。

摘要： A method and apparatus for performing file system operation locks at a database server is provided. A request to perform a file operation on a portion of a file managed by a database server is received at the database server. In response to receiving the request, the database server grants a lock that covers only a portion of the file that is involved in the file operation. For example, the database server may grant a lock that covers a range of bytes on the file, where the range of bytes is less than the entire file. Thereafter, the database server performs the file operation on the file. The file operation may be a NFS operation.
摘要翻译：提供了一种用于在数据库服务器执行文件系统操作锁定的方法和装置。在数据库服务器处接收对由数据库服务器管理的文件的一部分执行文件操作的请求。响应于接收到该请求，数据库服务器授予仅覆盖文件操作中涉及的文件的一部分的锁。例如，数据库服务器可以授予覆盖文件范围的字节的锁，其中字节的范围小于整个文件。此后，数据库服务器对文件执行文件操作。文件操作可能是NFS操作。

摘要： A hierarchy may be explicitly or implicitly reflected in existing data maintained external to hierarchy structures. Such hierarchies are referred to herein as a "pre-existing hierarchies". Techniques are described herein for capturing a pre-existing hierarchy in hierarchy structures. After a pre-existing hierarchy has been captured, there exist two independent sets of data that reflect the hierarchy: the external hierarchy definition and the internal hierarchy definition. Changing either hierarchy definition changes the hierarchy. Therefore, to maintain a consistent reflection of the hierarchy, the internal hierarchy definition must be modified in response to changes made to the external hierarchy definition, and the external hierarchy definition must be modified in response to changes made to the internal hierarchy definition. Various techniques are described for maintaining consistency between the two hierarchy definitions.
摘要翻译：层次结构可以在层次结构外部维护的现有数据中显式或隐式地反映出来。这样的层次结构在本文中称为“预先存在的层级”。这里描述了用于在层次结构中捕获预先存在的层次结构的技术。在捕获了一个预先存在的层次结构之后，存在反映层次结构的两个独立的数据集：外部层次结构定义和内部层次结构定义。更改层次结构定义会更改层次结构。因此，为了保持层次结构的一致反映，必须根据对外部层次结构定义所做的更改来修改内部层次结构定义，并且必须根据对内部层次结构定义的更改来修改外部层次结构定义。描述了用于维持两个层次结构定义之间的一致性的各种技术。
