[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3586) SequenceHiLoGenerator generates values ahead of the actual sequence

Robin Sander commented on HHH-3586:
-----------------------------------
I'm pretty sure this is not a bug. The multiplication is needed to "reserve"
a sequence of identifiers without
hitting the database for every one, imagine using this in a clustered environment or
simply using the same
sequence for multiple types.
SequenceHiLoGenerator generates values ahead of the actual sequence
-------------------------------------------------------------------
Key: HHH-3586
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3586
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1
Environment: Hibernate 3.3.1, Oracle 10G
Reporter: Krasimir Chobantonov
Original Estimate: 1 hour
Remaining Estimate: 1 hour
The code that needs to be change in on line 83 of the SequenceHiLoGenerator
here is the line
hi = hival * ( maxLo+1 );
basically we should add (+) the maxLo +1 to the current sequence value represented bu the
hival instead of using multiply (*)
