Using document body compression
Use the advanced database property Compress document data to reduce the total cost of ownership of maintaining any Notes® database by compressing non-summary item data in all documents in a selected database. Document compression can provide up to a sixty percent size saving.

About this task

Note: To use this feature, the NSF must be ODS 48 or later. To upgrade a database to ODS 48, enter the following setting in your NOTES.INI file and use copy-style compacting on the database:

Create_R8_Databases=1

You can upgrade all the way to the current level of ODS (which provides more benefits than ODS 48) by entering:

Create_R85_Databases=1
