If you are running NSFDB2, or are thinking about it technote 1384421 is for you. The technote covers the plans for NSFDB2 and it’s support. In short, there are no plans to add any additional functionality, and DB2 9.1 is the supported version. Support though will continue
What will happen with my existing applications that utilize the NSFDB2 feature? The NSFDB2 feature in Lotus Domino is still supported and defect issues related to the feature will be investigated and addressed as appropriate. How long will there be support for the ability to use NSFDB2? Support for the NSFDB2 feature will be continued in the Lotus Domino codestreams where this functionality is available (currently Domino 7.0.x, Domino 8.0.x, Domino 8.5.x) for a minimum of 5 + 3 years. Following IBM’s software support policy, this would be at least until 2017 for the Domino 8.5 codestream, as the initial release of Lotus Domino 8.5 was in January 2009.
