Aside from installing SSAS, I have no experience using it.
Our developers are saying that it is no longer possible to create a new aggregation, whatever the cube.
The error occurs when hitting Start.
Here is what I found in the msmdsrv file
Type: 3, Category: 289, Event ID: 0xC1210012
(7/30/2014 10:55:10 AM) Message: Errors in the metadata manager. An error occurred when instantiating a metadata object from the file, '\\?\E:\MSAS11.DWH_AS\OLAP\Data\Cube Fraude.0.db\MY_DATABASE OLAP.56.cub.xml'. (Source: \\?\E:\MSAS11.DWH_AS\OLAP\Log\msmdsrv.log, Type: 3, Category: 289, Event ID: 0xC1210012)
The file E:\MSAS11.DWH_AS\OLAP\Data\Cube Fraude.0.db\MY_DATABASE OLAP.56.cub.xml has 0kb, so should this file be removed?
Any help on resolving this issue would be appreciated.
