Re: sequences

Hoping that your application can tolerate skipping some sequence values, One simple way that I use to refresh sequences is :

1. Make note of the increment by value for sequence(s1) on source database.
2. Get last_number from dba_sequences at the source database for s1. Last_number will provide the last cached value.
3. Alter the sequence on destination database and set 'increment by' to a value found in step 2.
4. Issue 'select s1.nextval from dual' to make sure that sequence moves to the expected value.
5. Change the increment by value back to the one identified in step 1.
