Abstract: Provided is a method, system, and program for accessing data in a distributed database environment. A client program receives multiple requests for data from a database object satisfying specified search predicates from an application program. Each request includes a request for at least one row from the table. The client program transfers a database command and a rowset parameter indicating a maximum number of rows to return to a server program over a network if the requested row is not maintained by the client program. A data block is generated with the server program including rows from the database object satisfying the search predicates in response to the database command. The rows included in the data block do not exceed the rowset parameter. The server program transfers the data block to the client program. In turn, the client program returns at least one requested row from the received data block in response to one request for the at least one row of data from the application program.

Abstract: 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.
