Class SolveCommand

java.lang.Object

oracle.olapi.syntax.BuildCommand

oracle.olapi.syntax.SimpleCommand

oracle.olapi.syntax.SolveCommand

public final class SolveCommand
extends SimpleCommand

A SimpleCommand that initiates the operations that calculate the data for the measures of an MdmCube. You get an instance of a SolveCommand by using one of static constant fields of the class. You add a SolveCommand after a LoadCommand in the list of build commands in the BuildSpecification that you associate with the MdmCube.

For an MdmCube that is partitioned, you can specify a serial solve or a parallel solve. A serial solve calculates the data for the measures of the partitions serially, using a single process, regardless of the parallelism setting specified by the BuildProperties object that is associated with the BuildProcess that includes the cube. A parallel solve calculates the data for the measures of the partitions simultaneously, using one process for each partition, or as many processes as are available. If the partitioning of the cube does not match the partitioning of the source table, then a serial solve is a good choice.
