Map packages to namespaces.


[Map.w]    Package_PackageName=Database


Whenever a namespace (w) contains mappings, InterSystems IRIS® data platform creates a section in the configuration parameter (CPF) file called [Map.w] for that namespace. For example, mappings for the USER namespace appear under the section [Map.USER]. The [Map.w] section contains every global mapping, routine mapping, and package mapping for that namespace.

Package mappings take the form Package_PackageName, where PackageName is the specific package that is being mapped. Each package entry contains a database location (Database) that contains the named package. Classes in the specified package become available in the w namespace.

For more information about mappings, see the Add Global, Routine, and Package Mapping to a Namespace section of the “Configuring InterSystems IRIS” section of System Administration Guide.
