CREATE_R8_DATABASES=1 will enable ODS 48, which provides significant performance improvements.
When a new application is created in a Lotus Notes 7, 8 or 8.5 client or on a Lotus Domino 7, 8 or 8.5 server, the on-disk structure (ODS) remains at 43, which is the ODS version introduced in Notes/Domino 6. The on-disk structure has been upgraded in Notes/Domino 8 to the new ODS version of 48. However, it is not enabled by default for new or upgraded applications. This default behavior deliberately avoids forcing ODS upgrades during DB compact, which can be unexpectedly time-consuming. Running 'compact' against the application will not upgrade the ODS unless CREATE_R8_DATABASES=1.
This setting has no effect on DB2-enabled Notes databases.
There is no UI equivalent for this setting.
If CREATE_R8_DATABASES is absent or set to 0, then the file format of any new or compacted database will default to ODS version 43
Add CREATE_R8_DATABASES=1 to NOTES.INI to enable ODS 48 (Version 8) as the default. New applications and updated applications (via 'load compact -c') will now be upgraded to the new ODS. This is strongly recommended because of the significant performance improvements built into ODS 48.
This configuration is valid for Domino 8.0 and beyond
Changes to this setting are dynamically detected. A server restart is not necessary.
