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?
