ACS primary/ secondary config

[ngo duyen]

we have 4 ACS in the system: 

+) In HQ, we have 2 ACS: 1 primary and 1 secondary ACS

+) In Branch office, we have 2 secondary ACS

I suppose Primary fail, could one of secondary ACS automatic become primary so all other ACSs can continues replicate from that one ?

If not, when primary fail, we have to go each secondary and deregister. After that we choose one of 3 ACS as primary and register to that one ?

Thanks

Hey Duyen,

so you are only care about replication? right?

unfortunately if primary fails in replication there is no way for any secondary to take the role of primary and replicate to others (this is in ACS 4.x only. I don't know about 5.x).

So what you need to do is just what you metnioned, to go to each ACS server, configure one of the secondaries as primary and configure others to replicate from this new primary one.

Regards,

Amjad

Do you know ACS 5.x can do automatic take role of primary?

In the case of a primary ACS fails the secondary will perform the functions!Now replication can be forced manually, or you must remove the record from secondary to primary manually promoting it too!

hi Jonatas,

Does thats mean I have to manual take role primary as ACS 4.x ?

when primary down, we have to deregister all 3 secondary and choose 1 primary from 3 ACS and ...

Thanks
