Explanation:
When a new application is created in an IBM® Notes® 9.0.1 Social Edition client or on an IBM Domino® 9.0.1 Social Edition 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 9.0.1 Social Edition to the new ODS version of 52. However, it is not enabled by default for new or upgraded applications. This default behavior deliberately avoids forcing ODS upgrades during database compact, which can be unexpectedly time-consuming. Running 'compact' against the application will not upgrade the ODS unless a NOTES.INI setting such as CREATE_R9_DATABASES forces the upgrade.

There is no UI equivalent for CREATE_R9_DATABASES.

Note To allow compression of document data or consolidation of attachments through the Domino Attachment and Object Service (DAOS), NSFs must be at least ODS 51.

Default:
If CREATE_R9_DATABASES is absent or set to 0, the file format of any new or compacted database defaults to ODS version 43.

Recommendation:
Add CREATE_R9_DATABASES=1 to NOTES.INI to enable ODS version 52 as the default. New applications and updated applications (via 'load compact -c') will now be upgraded to the new ODS for release 9.0.1 Social Edition. If you use database encryption, this is strongly recommended over previous ODS levels, due to a potential note corruption issue which has been addressed in ODS 52.

Restrictions:
This configuration is valid for Notes and Domino 9.0.1 Social Edition and beyond.

Restarts:
A server restart may be necessary in order for this change to take effect.
