Locates objects

CMIP services allows your application program to target CMIP requests to local or remote objects without knowing where the objects reside, what their application entity titles are, or what their associations are. The directory resolves the object locations. Application programs can use the same code for local objects and for remote objects.

CMIP services maps an object instance, represented by its distinguished name, to the application entity title of the application entity that can be used to contact that object instance.

CMIP services performs the following tasks:

Maps distinguished names to application entity titles by using a locally defined directory and either of the following methods:
- Mappings (as defined by either the ACYDDF member of the SYS1.SISTCMIP data set or a CMIP algorithm) for distinguished names of specific formats to the application entity title that represents the distinguished name.
- User-defined mappings for distinguished names of specific formats to the application entity title that represents the distinguished name and from application entity title to session address. See z/OS Communications Server: SNA Network Implementation Guide and z/OS Communications Server: SNA Resource Definition Reference for more information about user-defined mappings.
Maps names to application entity titles by using a locally defined directory.

CMIP application programs can rely on CMIP services to provide this mapping. The application programs address the objects by their distinguished names only.

Only one mapping is allowed. You cannot define more than one application entity title for each distinguished name and cannot target more than one target system per application entity title.
