Hi,
We have two domino servers setup, server A and server B such that they are in the same cluster. Replication happens as expected between these two servers. We are trying to simulate a failover scenario for some testing purposes.
To simulate the failover scenario, we have set the SAT(Server availabilty threshold) to 100 so that the domino server A is busy and it will redirect any new requests to the backup server B. But even though we set this up, the user is able to access the mailbox from the server A and no failover happens. We have tried setting the parameter Server_TransInfo_Normalize to values 600, 400 but did not succeed to simulate a failover to the backup server
Are there any othe parameters to be set for the failover to happen?
Are we missing some setup?
Any information in this regard will be higly appreciated.
Thanks

Here is some information that may be helpful to you.
Clustered servers with the Server_Availability_Threshold=100 (busy state), will allow users with Manager access to open databases instead of redirecting their database open request to another server in the cluster. Users without manager access are redirected to a secondary server.
Manager Access to a database provided by Full Access Administration will allow users database access to a busy server. Users with basic Manager access should failover to a secondary server if available. Replication of database will not be affected.

Second one is titled: What is failover and when does it happen in a clustered Domino server environment?
Hope this helps!

Many thanks for the repsonse
I have tried changing the access to Editor by updating the ACL and then replciate the failover. But it did not work.
I am really missing something here
Thanks

Does anyone know if the SERVER_AVAILABILITY_THRESHOLD=100 behaviour has been fixed in domino 8.5.2 please ?
