Hi all,

I am working with TM1 9.4.1, trying to copy cubes from a remote server(source) to the local server( running as independent process), and synchronize data between the two servers.
It really works well when I copy data model and data point values from the source server, also I can write back to the source server when I modify the data point values and press 'Synchronize All Data'.
Sth strange occurs when I try to modify the dimension structure, e.g. I insert an element into the dimension, the modification will not be reflected in the source server after the synchronization, instead, the data model will be copied from the source server to local server, then the modification in local server is lost
I can't figure it out even with the operation guide.
Does anyone have similar experience or do you have any advice?
Waiting for your kind help.

I've been playing around with this on 9.0 just this week as it's helping loads with a new build. Personally i wouldn't trust local services as far as i can throw Everest, they just don't always behave the same way as a remote service. I did find out that the destination service needs to be registered with the same admin server the source is running on, otherwise it does some things but not others.

Not sure what "directional" settings you get in 9.4 replication but i've not found a sync one way or another option in 9.0, so i'm not sure why yours would do it from source to destination only. Personally i'd try the same thing on 2 remote services and see if its still doing the same.

It's really kind of you, Steve

I tried replication in 9.0 SP2 and failed again
It still copy data model from source to destination only,even if I modified the dimension in source server first.

I remember it is recorded in the operation guide as follows:

IBM® Cognos® TM1 Operations Guide wrote: TM1 also updates the replicated dimensions if you made changes to their definitions and rules.

IBM® Cognos® TM1 Operations Guide wrote: If there is an update conflict for a particular cell, TM1 uses the most recent update, no matter where this update was made (that is, in the source cube or the mirror cube).

I'm confused

not got a chance today but i need to do more with my replications at soem point. I'll test this at the same time and let you know.

Is your replication account on the star an admin? I haven't used local servers much, but that's the only thing I can think that might cause this.

Matt

both accounts are admin, and both servers are running as a remote server

It still doesn't work
