I prefer:
Create sequence my_seq_in_database_1 start with 1 increment by 2;
Create sequence my_seq_in_database_2 start with 2 increment by 2;
That way, you don't have to pick some preset upper limit, and you will
never get a collision.
If you want the flexibility of adding other sources in the future, you
could increment by 10, above. That way, you could add up to eight more
sequences in the future.
Hope that helps,
-Mark

In case you need not to get overlapping values you can simply define one
sequence with values starting from 1 to very big number and the other
from the very big number till very big number * 2 Or the other with just
start with -1 increment by -1
Of the overlapping sequences is not the case, then what is the problem?
