Abstract: Provided is a method, system, and program for implementing a database trigger. Upon detecting a trigger event, a determination is made of at least one row in a base table affected by the trigger event. For each column in the base table of a data type that is referenced in a triggered action associated with the trigger event, a reference is generated referencing the data of the data type. The reference is inserted in a transition table column including data of the data type from the affected row in the base table referenced in the triggered action. The reference is used to access the data of the data type when performing the triggered action.

Abstract: Aspects for dynamically changing attributes in an embedded-SQL application are described. In these aspects, an option is provided within a standard SQL statement for specifying one or more attributes of at least a declared cursor. The standard SQL statement is then processed to include the specified one or more attributes in at least the declared cursor. The provision occurs with an ATTRIBUTES option and within a PREPARE SQL statement.

Abstract: A method, apparatus, and article of manufacture for a computer-implemented apportioning system. Work is distributed to processors in a multi-processor system. Initially, during bind-time, a scaling factor is determined for each processor. The scaling factor represents relative processing power in relation to each other processor. Then, portions of a total amount of work are distributed to each processor based on the determined scaling factor of that processor and a determined amount of work for an average processor.

Abstract: A system and method for a computer system having a plurality of DBMS providing a coordinating and assisting function. If a DBMS performs a coordinating function, it is referred to as a coordinating DBMS. If a DBMS performs an assisting function, it is referred to as an assisting DBMS. Each coordinating DBMS receives a query from a user application, decomposes the query into multiple parallel tasks, and allocates the parallel tasks to all of the DBMSs in the system. Each assisting DBMS receives one or more parallel tasks from a coordinating DBMS, executes the parallel tasks and returns the results to the coordinating DBMS. The coordinating DBMSs and assisting DBMSs access one or more storage devices. Furthermore, the present invention comprises a system and method for dynamically disabling a parallel mode on the coordinating DBMSs and the assisting DBMSs.
