HI 

I am installing one identity manager 9.0 LTS version when I get to schema creation I get the following error.

Processing step 'QER ContentInitial (fill initial content for insert)' failed.
6 - DataFile command failed.
The database connection was broken.
Object reference not set to an instance of an object.

Please help in this issue.
