Abstract

A prototype object reference for use in a distributed object computing environment is described. The object reference includes a specified object reference portion and an unspecified object reference portion. The prototype object reference is transformed into a valid object reference by insertion of specification information into the unspecified object reference portion and the specified object reference portion is not fully parsed in connection with insertion of the specification information.

Claims

1. A system for facilitating object migration in a distributed object computing environment, comprising:

a location service comprising one or more repositories;

said repositories retaining an object reference, said object reference including an endpoint identity, said endpoint identity mapped to an endpoint location;

said repositories retaining an endpoint location to process name mapping, and

wherein the object reference to endpoint location mapping is independent of the endpoint location to process name mapping allowing migration of objects while retaining object location and process association capabilities.

2. The system of claim 1, further comprising:

a process name to process activator mapping.

3. The system of claim 1, wherein selection of a process activator from a plurality of process activators corresponding to a process name is determined by a criterion.

4. The system of claim 3, wherein the criterion may be determined at run-time.

5. The system of claim 1, wherein a plurality of location identifies are mapped to a single process name.

6. The system of claim 1, further comprising:

a process name to active process mapping.

7. The system of claim 6, wherein a single process name is mapped to a plurality of processes.

8. The system of claim 7, wherein selection of a process from a plurality of processes corresponding to a process name is determined by a criterion.

9. A system for facilitating object migration in a distributed object computing environment, comprising:

an object location service retaining a current endpoint identity to endpoint location mapping;

said endpoint location identified to said object location service by a server for each endpoint;

said location service retaining an endpoint location to process name mapping, and

wherein the endpoint identity to endpoint location mapping is independent of the endpoint location to process name mapping allowing migration of objects while retaining object endpoint location and process association capabilities.

10. The system of claim 9, further comprising:

a process name to process activator mapping.

11. The system of claim 10, wherein selection of a process activator from a plurality of process activators corresponding to a process name is determined by a criterion.

12. The system of claim 11, wherein the criterion may be determined at run-time.

13. The system of claim 9, wherein a plurality of location identities are mapped to a single process name.

14. The system of claim 9, further comprising:

a process name to active process mapping.

15. The system of claim 14, wherein a single process name is mapped to a plurality of processes.

16. The system of claim 15, wherein selection of a process from a plurality of processes corresponding to a process name is determined by a criterion.
