Changes in This Release for the OLAP Java API

This page lists the changes in the Oracle OLAP Java API.

Changes in Oracle Database 12c Release 1 (12.1)

The following are changes in the Oracle OLAP Java API for Oracle Database 12c Release 1 (12.1). For changes in previous releases, see Changes in Previous Releases.

New Features

The following features are new in this release:

• Varying the aggregation method of a measure depending on dimension members or attribute values.

  In implementing this feature, the following classes in the oracle.olapi.syntax package have new methods:

  • AggregationCase
    • Constructors that take an aggregationSwitchValue parameter that specifies an attribute value or a dimension member
    • getAggregationSwitchValue()
    • getMeasureID()
  • AggregationCommand
    • Constructors that take an aggregationSwitch parameter that specifies an attribute value or a dimension member
    • getAggregationSwitch()
    • getAggregationSwitchID()
• Specifying no aggregation for a dimension in an AggregationCommand.

  If you specify NO_AGGREGATE as the function of an AggregationCommand, then Oracle OLAP does not aggregate the values of the measure for the specified dimension.

• Preventing changes to the parentage of a previously loaded dimension member during the load of a dimension.

  In implementing this feature, the LoadCommand class has the new static fields RETAIN and RETAIN_OPTION.

• Specifying the OLAP DML $LOOP_TYPE system property for an MdmDerivedMeasure.

  The $LOOP_TYPE property determines how Oracle OLAP loops over composites for an MdmDerivedMeasure that has an Expression that references measures from more than one cube. The MdmDerivedMeasure has new static constants and methods that you can use to get or set the type of looping.

• A base class for objects that you can export to XML.

  The PublicMetadataObject class is the base class for OLAP Java API objects that you can export to XML. You export objects to XML by using methods of an MdmMetadataProvider.

Desupported Features

Some features previously described in this document are desupported in Oracle Database 12c Release 1 (12.1). See Oracle Database Upgrade Guide for a list of desupported features.
