    If db1 and db2 are supposed to run on the same node (ie: they're not supposed to run on different nodes), then you only need one group.

    Add TaminoSrv DB2 resource to the existing Tamino group.

    Ensure the TaminoSrv resources are non-critical (Critical = 0) so if they fault they won't trigger failover (in your configuration they were already set as Critical = 0, but just make sure when you re-add the resource).

    If both databases rely on sag2utx, ensure you configure this dependency.

    So, if configured this way, when the group is brought online, after sag2utx is started db1 and db2 will be started.

    If db1 faults, the group will not failover, and unless there is dependency between the databases db2 should still remain up, and vice versa.

Hi Lee

 

sorry for late answer, i was sick and not at work.....no the two databases should run on the same node, but the key target should be that if one database crashes the other one should not be restartet through the VCS. I think that the proxy resources would be the best for it?
Sorry for my bad english, hope you can understand what i mean

 

Kind regards
