This setting affects only NSFs; it has no effect on DB2-enabled Notes databases.
While we do not suggest upgrading the ODS during the upgrade process itself, you can add this notes.ini parameter prior to upgrading to Domino 8, pre-Domino 8 servers ignore this setting, so it is safe to set this parameter even in a mixed version environment.
Additional Information:
The term On Disk Structure (ODS) describes the internal architecture of Notes databases. Each new release, except ND7, has included an update to the ODS to accommodate new features and functions.
Upgrading a database to Domino 8’s new ODS48 does not occur automatically when a database is compacted. You must first add this parameter to the NOTES.INI on the server or client.
Create_R8_Databases=1
After you add this parameter and restart the server, every new database you create and every database you compact will be using the new ODS.
Use the “copy style” compact command at the console to upgrade existing databases to the new ODS once you have added the parameter.
Load compact –c
Pre-Domino 8 servers will ignore this parameter, by the way.
Having to add this parameter lets administrators decouple the ODS upgrade from the server upgrade, and to control when and how the new ODS will be implemented on servers and clients. It’s always a good thing to be in control during an upgrade.
Keep in mind that the ODS itself does not replicate from server to server. You have to add the parameter to every server that should be using the new ODS.
OSD Advantages
So what do you get with the new ODS? You get a couple of really cool features. Admittedly, some are cooler than others. First, there’s design compression, which reduces the size of databases by compressing design elements by up to 60%.
NOTE: This also works on the workstation, you will need to run compact from the command prompt to update the current databases.
To reduce the size of dbs on your workstation use:
NCompact -c -ZU -n -v -c Copy style compact, used to put db in new ods format. -ZU Converts document attachments using compression type Huffman to LZ1 if db property is set. -n Compress design -v Compress data
