Objectivity/DB 9.0 (prior release) - Feature Additions

Objectivity/DB Release 9.1 - Feature Additions

Objectivity/DB 9.1 - JCA Support and Faster SQL++

JCA - A new Java Connection Architecture resource adapter feature allows Objectivity to plug into any application server supporting JCA, enabling use of the CCI interface to manage connections to the Enterprise Information System (EIS), instead of requiring manual, vendor-specific connection management coding. Besides the current support for BEA WebLogic Container Managed Persistence, a CMP deployment tool for IBM WebSphere is now also included.

AUTOMATIC RELATIONSHIP TRAVERSAL FOR SQL++/ODBC

Automatically trigger use of OOTRAVERSE(), leveraging relationship traversal where possible when processing application-generated queries such as those initiated from Crystal Reports. The performance of queries involving relationships will often be significantly improved.

Other Features

OID PRESERVATION

A new clustering directive oocSameId is now available to support creation of an object with enforced use of an object identifier (OID) supplied by the application. If the given OID is logically impossible, an exception is thrown. This is useful, for example, in re-creating a deleted object to which there are pre-existing external unidirectional references.

OOUPGRADE

Migrates an existing federated database to the new Release 9 catalog format, specifying migration of the entire federation, just the system database, or any single database. All object identifiers are preserved, so an upgraded DB continues to be interoperable with pre-upgraded DBs. The tool can also impose a new page size or a new native storage page owning architecture (Linux, Windows, etc.) for the migrated data.

OOFIX

An interactive command-line tool for repairing certain database problems using mechanisms previously available only to Objectivity support engineers.
