Cant connnect to sql catalog.

When i try to connect to sql catalog using
Userid: DBA
it gives me following error.

8203(E): You have not a valid license or your license has expired for this component; 8600(E): internal error in SQL enginelnk with internal code -35 SAGCONM(1)

Apart from this evrything is running fine

you need a license that includes the SQL. By default this is not included. If you wish to enable the SQL side of Tamino please contact your local Software AG office and they would be able to generate a new license key that includes the SQL options.
