hi all,
question:
is it possible to preserve sequences without gaps?
is it reasonable to use dbms_shared_pool.keep function in order to prevent sequences from aging and being dumped?
thank you,

Hi
1. No. You cannot guarantee that a sequence will have no gaps.
2. For faster access to sequence values use the cache setting to cache multiple values for the sequence.

Here is a link to some documentation on sequences.
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_615a.htm#2080641
You may also want to serch these forums for many varied discussions on the topic of sequences.
