Default Shared dimension clarification needed - 12-01-2003 , 11:45 AM






Hi,
I know that dimensions are loaded in memory all the time when analysis
services start .
Now are the private dimensions also loaded in memory?

2. We can use shared dimensions in multiple cubes . In that case are copies
of shared dimensions created for each cube ?

3. We can disable levels of shared dimensions selectively , in that cases
are dimensions replicated in memory ?
Regards,
Akshay

All dimension members in all databases are loaded into the msmdsrv process
address space -- private and shared -- it makes no difference.

No. There is one version of the member, regardless of how often it is used.
However, if you are using dimension security, then additional copies can be
loaded into what is called "replica dimensions". See the discussion of
replica dimensions in:

Disabling a level has no impact. All dimension members in all databases are
loaded when the msmdsrv service starts up; and are updated when any
dimension is processed.

Hope this helps.
