Recently, a support ticket came in with the following problem: Executing "Adam.Core.DatabaseManager.exe UpdateSchema" failed with the error message 'You can only specify the READPAST lock in the READ COMMITTED or REPEATABLE READ isolation levels' (see screenshot).

Cause from this problem? Replication was on enabled on the specific database. Because ADAM does NOT support replication on databases, you should temporary disable replication when executing UpdateSchema.
