System Copy Issue

I've done an homogeneous system copy using a redirected restore of our PROD system to a Sandbox system.

In the Sandbox system, I now see the following in the system log :

08:11:42 BTC 003 000 DDIC BY 2 Database error -727 at OPC

08:11:42 BTC 003 000 DDIC BY 0 > SQL0727N An error occurred during implicit system action

08:11:42 BTC 003 000 DDIC BY 0 > type "3". Information returned for the error includes SQLCOD

08:11:42 BTC 003 000 DDIC BY 0 > "-204", SQLSTATE "42704" and message tokens

08:11:42 BTC 003 000 DDIC BY 0 > "SYSTOOLS.ADMINTASKS". SQLSTATE=56098

08:11:42 BTC 003 000 DDIC BY 1 Database error -727

I also see similar messages in the db2diag.log file.

Any ideas why ?

Thanks,

Robert
