    摘要: A method and apparatus for configuring a plurality of server systems. In one implementation, the method includes configuring the plurality of server systems as a first database having a group name and a group port, and configuring a subset of the plurality of server systems as a second database having a subset name and a subset port. The first database is accessible by a client application via the group name and the group port for storage of data in the first database, and the second database is accessible by a client application via the subset name and the subset group for storage of data in the second database.

    摘要: In a system for avoiding section collision for application server requests over a single database connection, the database server assigns query identifiers to each instance of the same cursor opened for the same processing level within an application, allowing multiple instances of the same cursor to be processed in parallel without section collision. The application server assigns a command source identifier to each statement sent over a single database connection to uniquely identify the application source of the statement. This applies for multiples of the same statement sent by different application sources within the same application, for a single statement containing multiple application sources, and for multiple statements from different applications multiplexed over a single database connection. These statements can be processed separately from and in parallel with the each other without section collision.

    摘要翻译: 在用于通过单个数据库连接避免应用程序服务器请求的部分冲突的系统中,数据库服务器为应用程序内为相同处理级别打开的同一个游标的每个实例分配查询标识符,允许处理相同光标的多个实例 平行而无分段碰撞。 应用程序服务器为通过单个数据库连接发送的每个语句分配命令源标识符,以唯一标识语句的应用程序源。 这适用于同一应用程序中由不同应用程序源发送的相同语句的倍数,对于包含多个应用程序源的单个语句,以及来自通过单个数据库连接复用的不同应用程序的多个语句。 这些语句可以彼此分开处理,也可以彼此并行处理,而不会出现部分冲突。

    摘要: The present invention discloses a method, apparatus, and article of manufacture for transmitting data having non-standard data types between computers. A query is executed to retrieve data from a database. The database comprises data having standard data types and data having non-standard data types and is stored on a data storage device connected to a server computer. At the server computer, data having standard and non-standard data types is retrieved. An answer set is generated that comprises data having standard data types and one or more placeholders, wherein each placeholder represents data having a non-standard data type. The generated answer set is transmitted to a client computer. After transmitting the generated answer set, data represented by each placeholder in the answer set is transmitted to the client computer.

    摘要: Operating a parallel database server system, where the database server system comprises at least two database servers and one data source. A client identifier is received from a client requesting services from one of said database servers. Information associated with said client is retrieved. The client is allocated to one of said database servers based on the retrieved information.

A query is executed to retrieve data from a database. The database comprises data having standard data types and data having non-standard data types and is stored on a data storage device connected to a server computer. At the server computer, data having standard data types, small non-standard data types, and large non-standard data types is retrieved. An answer set is generated that comprises data having standard data types, small non-standard data types, and one or more placeholders representing data having the large non-standard data types. The generated answer set is transmitted to a client computer. After transmitting the generated answer set, data represented by each placeholder in the answer set is transmitted to the client computer.
