Download the latest release v2.5 from the Download Section.

New In Release 2.50 -

+ Recursive Queries (CONNECT BY) -- the new CONNECT BY construct supports recursive queries. A recursive query traverses a tree structure to produce a flat result set.

+ Enterprise Server only - Fault Recovery and Replication Enhancements:
- Increased reliability and bug fixes (see below),
- stay.active startup option for master server, to avoid a single point of failure for fault recovery situations, and
- Arbiter server for improved control of fault recovery and replication.

+ Rollback Log Improvements -- significantly reduced disk space requirements for the system rollback log (log00001.log).

+ Capability to Expand the Execution Sandbox for Database Objects -- the list of built-in packages and classes that are accessible from database methods can be expanded. The Maint utilities provide this functionality. This powerful capability enhances the flexibility and range of FirstSQL/J applications. Examples from expanding internal methods can include new classes for communication with external devices, other databases, email, and storage of XML data.

+ Improved Maint Command-line Utility -- The command-line utility, Maint, now provides better support for batch operation, when taking commands from a file.

+ Various Bug fixes.
