hello people,first off, domino clustering for us works fine. if i have a domino cluster with a server at site A, and another at site B. how can i configure it to force all users from site A to use this cluster server as the primary cluster. of cause if this server if offline, it will force the user to use the cluster at site B.
here is the catch, if the cluster server at site A is back online, how can we automate these users be use this cluster server as the primary again???
this has been racking my brain for the last 2 days. i need this to be automated??
thanks in ADVANCE for the help.

Hi,
To setup a member server of a cluster as primary server(actually home server), you need to ammend the person document and place the server you want as Home server, and t=when ever the server is down, users will failover to the available server in the cluster, this failover is guided by the availability of the server.
Now come to availability…as you are aware of the notes.ini busy parameters( server_maxusers=xxxx). You need to setup this parameter correctly, if the number of users connected to a server reaches the set number then the connections will be diverted to the availble server in the cluster. Again two parameter guide the diversion to the free server namely: server_maxsessions=xx and Server_availabiltythresold=xx(will not be more than 100), and server_transinforange=xx( number should be based on the eexpansion factor calucated during the server offload and full load periods. these all above mentioned parameters guide the server diversion of session when the server is busy.
Now if you want to automate the users to fail back to their home server…I think there is no settings as such… u can simply drop all the users from the secondary server once the primary server is up and running, then the users will automatically move back to the primary server.

Thank you so much for your quick response:“Now if you want to automate the users to fail back to their home server…I think there is no settings as such… u can simply drop all the users from the secondary server once the primary server is up and running, then the users will automatically move back to the primary server”
i too didnt think that there was any automated way to transfer the users back to the primary server.
i do understand about the parameters, but thanks heaps anyway.
it maybe something that Lotus might think of for the next release?
if anyone else knows something that is of value, please share.
thanks again.
