Hi,
We have setup two servers in a cluster.
We activated DAOS for both servers.
It appears that users registered on the first server cannot access attachments stored at the second server and vice versa.
Is there a particular way to set up DAOS in a clustered environment ?
Thanks in advance for your help.

I think we found the root of the problem :we activated DAOS on some databases, and did an OS copy of these ones to the other cluster member.
The OS copy doesn’t keep the link to the DAOS repository on the first server.
We plan to desactivate DAOS, then do an OS copy, and then activate DAOS.

DAOS can’t be replicated. The DAOS store is specific to the server it’s on. So Server B would never be able to see the store on Server A even if they are clustered. When a database on server A replicates to server B the attachments are pulled from the catalog and inserted back into the nsf the way they were pre DAOS. Also, DAOS is encrypted by default with the server ID, so NLO files from server A couldn’t be copied to server B and read. Each server has to maintain their own catalog. You can turn encryption off, but not retro actively you have to remove DAOS, disable encryption and then re-enable DAOS. I think this is an area that IBM should look at improving, creating a central DAOS catalog that could be used by all cluster members.
