摘要： A method and system of subsetting a group of server systems configures a server system with a group name and a group port, and with at least one subset name and subset port. The server system, when activated, reads its configuration and registers with a system routing entity as being part of the group name and the group port, and as being part of the subset name and the subset port. In this manner, server systems can be targeted via its subset name and subset port, while also accessible via the common name and port for the group. If the group includes a workload balancer, the server system also registers with the workload balancer using the group name and the subset name, such that workload balancing is provided for the subset.

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： A shared memory device called the Coupling Facility (CF) is used to record the indoubt transaction entries for each member of the database cluster, avoiding the CPU cost and elapsed time impact of persisting this information to disk (either via a log write or a relational table I/O). The CF provides full read/write access and data coherency for concurrent access by all the members in the database cluster. At any given point in time, the CF will contain the full list of indoubt transactions for the entire database cluster. CF duplexing is used to guarantee the integrity of the CF structure used for the indoubt list. In the event of complete loss of both CF structures (which will not happen except in major disaster situations), data sharing group restart processing can reconstruct the CF structures from the individual member logs.
摘要翻译：称为耦合设施（CF）的共享内存设备用于记录数据库集群中每个成员的不确定事务条目，从而避免将此信息持续存储在磁盘上的CPU成本和耗时时间（通过日志写入或关系表I / O）。 CF为数据库集群中的所有成员提供完全读/写访问和数据一致性并发访问。在任何给定的时间点，CF将包含整个数据库集群的不确定事务的完整列表。 CF双工用于确保用于不确定列表的CF结构的完整性。在CF结构完全丢失的情况下（除主要灾害情况外不会发生），数据共享组重新启动处理可以从各个成员日志中重构CF结构。

摘要： A method and system for providing package resolution in a database system is disclosed. The method and system comprise providing a statement within a server which allows an application to identify a list of package collections. The method and system further includes executing the statement to obtain the appropriate package. A system and method in accordance with the present invention provides a new current package path value, which is set via a statement referred to as Set Current Package Path. The SET CURRENT PACKAGE PATH statement allows the application to supply a precedence list of qualified package collections during execution time, therefore the scheme for resolving packages can be changed at any point during execution. The SET CURRENT PACKAGE PATH statement improves application development by making the package resolution mechanism less error prone and less tedious for the application developer, while providing an optimal-performance solution in the client-server environment.

摘要： In a method and 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： A method, apparatus and program storage device is provided for dynamic data formatting during transmittal of generalized byte string data across a computer network. Remote server dynamically changes format of each column string data value from the result set separately, according to actual size of the string data value, and returns it to a client. Small-size data value is returned in a single network return message as varchar type, in-line with the rest of the query data. Medium-sized data value is retrieved without locators and streamed in multiple return network messages in a separate data object following the query data and in the same response. Large-size data value is retrieved using locators and returned as a progressive reference in pieces of specified size, where each piece of data value is separately transferred under client's control when needed, thus eliminating the need to buffer large amount of data.
摘要翻译：提供了一种方法，装置和程序存储装置，用于在通过计算机网络传送广义字节串数据期间进行动态数据格式化。远程服务器根据字符串数据值的实际大小动态地从结果集中动态更改每个列的字符串数据值的格式，并将其返回给客户端。小型数据值在单个网络返回消息中作为varchar类型返回，与其余查询数据一致。在没有定位器的情况下检索中型数据值，并在查询数据和相同响应中的单独数据对象中的多个返回网络消息中流式传输。使用定位器检索大尺寸数据值，并以指定大小作为逐行参考返回，其中每个数据值在需要时在客户端控制下单独传输，因此无需缓冲大量数据。

摘要： An embodiment of the present invention enables manipulation of data on a remote server and ensures uniqueness of data identifiers in a multi-tier environment, where a database client communicates through one or more intermediate servers to reach the target server containing the remote database. In particular, a client system transmits a query to the target server via a gateway system and receives a handle or data reference and a query identification for subsequent manipulation of data residing on that target server. A new query identification is generated by the gateway system and mapped with the query identification of the intended target server. When the client system transmits a query with the gateway query identification, the gateway system performs a lookup operation to identify the corresponding target server and subsequently forwards the query and target server query identification to the identified target server for processing.
摘要翻译：本发明的实施例能够操纵远程服务器上的数据，并确保数据库客户端通过一个或多个中间服务器进行通信以到达包含远程数据库的目标服务器的多层环境中的数据标识符的唯一性。特别地，客户端系统经由网关系统向目标服务器发送查询，并接收句柄或数据引用以及查询标识，用于后续操作驻留在该目标服务器上的数据。新的查询标识由网关系统生成，并与目标服务器的查询标识进行映射。当客户端系统发送具有网关查询标识的查询时，网关系统执行查找操作以识别对应的目标服务器，随后将查询和目标服务器查询标识转发到所识别的目标服务器进行处理。
