I am Newbie to Hibernate.I have a table with primary key as autogenerate column.
I have given my mapping hbm file below

<hibernate-mapping>
<class name="sample.test" table="TEST" >
<id name="id" column="id" type="long" >
<generator class="sequence" >
<param name="sequence" >seq_test</param>
</generator>
</id>
....
.....

</hibernate-mapping>


My class contains:-

private long id;

public long getId()
{
return id;
}

public void setId(long id)
{
this.id = id;
}

However, this doesn't work properly for an oracle database unless you add allocationSize=1 to @SequenceGenerator. Does anyone how to do this? I can't find any documentation, which defines how to add another parameter for allocationSize (<param name="?">1</param>) in <hibernate-mapping>?

Can anyone please tell me the use of "allocationSize". I can't find any documentation for this.
