Abstract
Two developing technologies, namely Java Platform based on the Solaris Research VM and Sphere persistent store, have been re- cently combined to provide a new version of orthogonally persistent Java -PJama1. Having these powerful technologies, the developers were gi- ven an excellent window of opportunity to provide evolution support as a standard, scalable and reliable mechanism. This paper describes the issues arising during the design of the store level foundation for the evolu- tion technology, and our solutions. We have achieved our goals of making evolution scalable and recoverable, yet retaining the unchanged view of the “old object world” during object conversion, at a price of minor con- straints to the semantics of custom evolution (conversion) code. A way to remove this constraint is proposed.
