Removed properties and APIs

If you are migrating your configuration from an earlier release of WebSphere® eXtreme Scale, some features might be removed from this and earlier releases. Use the recommended migration action to determine how to update your configuration.

If a feature is listed as deprecated in Deprecated features, IBM® might remove this capability in a subsequent release of the product. Future investment will be focused on the strategic function listed under Recommended Migration Actions in Deprecated features. Typically, a feature is not removed until at least two major releases or three full years (whichever time period is longer) after the release in which that feature is deprecated. In rare cases, it might become necessary to remove features sooner; such cases are indicated clearly and explicitly in the descriptions of these deprecated features in Deprecated features.

The following information describes removed features, APIs, scripting interfaces, tools, and publicly exposed configuration data. Where possible, the recommended replacement is identified.

Removed items in Version 8.5

Table 1. Removed properties and APIs
Removed item	Recommended migration action
Keyword support: Keywords are string tags that can be applied to cache entries and later queried using ObjectMap API methods.	Use the index or query function to get objects with specific attributes.
MapAuthorization interface: This plug-in was used to authorize ObjectMap and JavaMap to access the principals that were represented by a subject object.	Use ObjectGridAuthorization to plug in authorization implementations. An ObjectGridAuthorization can be used to authorize permissions to ObjectGrid, ObjectMap, and JavaMap accesses.
WebSphere partitioning facility (WPF): The partitioning facility is a set of programming APIs that allowed Java™ EE applications to support asymmetric clustering.	You can configure partitioning with WebSphere eXtreme Scale.
StreamQuery: A continuous query over in-flight data stored in ObjectGrid maps.	None
