If you are using PL/sql then try to reference the sequence next value in
the update/insert statement itself. Aso the update/insert can return the
value of the sequence to a PL/SQL memory variable.

I did two statspack snapshots, one hour and forty minutes apart.
Then I generated a report and loaded it into oraperf.com.
In the report I saw that the two SQL statements that where executed the
most
times where:

Select xxxx.currval from dual;

Select xxxx.nextval from dual;.

Each one was executed about 90,000 times with 5 buffer gets per
execution.
The net result was about 950,000 buffer get for nextval and currval.

My question is:
Why should there be about 5 buffer gets per execution?
