Notes/Domino 8.5.3: Improving local replica efficiency

Recent versions of IBM Lotus Domino have included updates to the On-Disk Structure (ODS), the file format of Notes and Domino databases. However, if you have local replicas, they will not automatically be upgraded to the newer formats. In fact, even newly-created local replicas aren’t created in the new formats by default.

To fix this, add the following two lines to NOTES.INI while Notes isn’t running:

NSF_UpgradeODS=1
CREATE_R85_DATABASES=1

Now you can use the Admin client to compact your local replicas using copy mode, and it will upgrade them to 8.5 on-disk format, which is more space efficient and provides better performance.

I’ve no idea why this isn’t the default behavior. It made a huge difference to how snappy e-mail was for me.
