AlwaysOn Q: Read-only replicas for 2 different AGs in the same instance?

  • Hi,

    Does any know is it possible to have read-only secondary databases from 2 different AG groups on the same instance? This is to facilitate a reporting requirement where I would like read-only databases from 2 different instances to reside on the same instance (to avoid cross-instance queries etc)

    AG 1:

    OLTP1 (Prod, Primary): 5 databases - OLTP2 (DR, Secondary): 5 databases

    Databases:

    oltp1

    oltp2

    oltp3

    oltp4

    oltp5

    AG 2:

    DWH1 (Prod, Primary): 1 databases - DWH2 (DR, Secondary): 1 databases

    Databases:

    dwh1

    New Reporting Instance -

    Requirement: Read-only secondary of databases/replicas from the above 2 AG groups combined in this instance

    Databases (readonly):

    dwh1

    oltp1

    oltp2

    oltp3

    oltp4

    oltp5

    Thanks,

    Harvey

  • Thanks for posting your issue and hopefully someone will answer soon.

    This is an automated bump to increase visibility of your question.

  • If I understand you right this should be possible. We have a readable secondary reporting instance with two AGs where the primary replicas for these AGs are both different servers.
