Objectivity/DB 10.0 improves and speeds upgrade tasks, including changing from a 32-bit to a 64-bit representation on disk, all while the federation can remain online.
Objectivity occasionally upgrades the format of the system data structures or the schema used within Objectivity/DB. This can sometimes entail an upgrade of existing federations, at the metadata, database, container or page level. In many applications it is not feasible to take data offline while a whole federation is converted. Objectivity/DB 10.0 has an improved upgrade tool that can accomplish one-time tasks, such as upgrading catalog formats from pre-9.0 format to 9.0+ format, or changing from a 32-bit to a 64-bit representation on disk, while the federation is online.
