Thank you all for your replies.
Srv1's server doc has the following parameter "Server task / Domain Catalog / Basics / Domain Catalog" set to Enable.
All other servers has this parameter set to Disabled.
Result is that each server has it's own catalog.nsf filled with its own dbs.
>> I need to check this further more as the server was not rebooted after this modification but does it need it ?
I expected to have a "global" catalog on srv1 which will fetch catalogs on srv2, srv3 and so on...
But srv1 just have its own data....
Surprising as this line 14/06/2017 02:41:37 Pulled changes from catalog on SRVx/AAAA is found for all the other servers.
If I replicate from the other servers I will indeed get a result for any other server, but if so what is the purpose of a domain catalog ?
I do miss something in my understanding.
It might be usefull to know that I have a mix of Domino server version :
srv1 (domain server) is running 8.5.3
srv2, srv3, srv4, srv5,srv9 are running 8.5.3
srv6, srv8, srvt1, srvt2 are running 9.0.1
srv1 runs catalog task at 2:00
All other servers run the task at 1:00.
Once again thank you for any help.
