摘要： Techniques are provided for processing data. Connections having different security properties are stored, wherein each of the connections allows applications at the client computer to access data sources at a server computer. A request is received from an application to access a data source, wherein the request has associated security properties. In response to the client computer requesting establishment of a connection on behalf of the application, it is determined whether there is a stored connection that used a same set of security properties as are associated with the request from the application and that connected to the data source that the application requests access to. In response to determining that there is a stored connection that used the same set of security properties and that connected to the data source, the connection and an associated client encryption seed, client encryption token, server encryption seed, and server encryption token are re-used. In response to determining that there is not a connection that used the same set of security properties and that connected to the data source, a new client connection key, client encryption seed, client encryption token, sever connection key, server encryption seed, and server encryption token are generated.

摘要： A method for generating an execution plan for updating and retrieving data from a database in a single process includes: receiving a statement by a server to update a database with a first set of data and to retrieve a second set of data from the database; building a first execution plan to update the database with the first set of data; building a second execution plan to retrieve the second set of data from the database; and building a single execution plan including a combination of the first and second execution plans. The single execution plan allows for the updating and retrieval of data with a single crossing of an interface between a client and the database. By performing both functions in this manner, the efficiency of performing such tasks on the database is significantly increased.

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 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： System, method, and program product for managing transactions on a plurality of Database Management Systems residing on separate participant servers and a coordinator server. A single transaction proceeds by multiple steps across more then one of the plurality of Database Management Systems as participants. Savepoints are assigned to the participants across the Database Management System, with at least one savepoint within a multiple step transaction. The DBMS responds to application requests to rollback to savepoint by rolling back the transaction, across the Database Management System participants, to the savepoint Further disclosed is a program product that contains code, which, either as written on the medium, or as instantiated in RAM, or both, controls the operation of a distributed database management system.

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： 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.
