update allocationSize of Sequence table [message #756874]

Hello,

We're using a primary key generator of type TABLE. By now we used the default value of allocationSize 50. But we have some problems with concurrency and we want to update allocationSize to 1. We've tried doing this:
@Id
@TableGenerator(name = "ID_GENERATOR", table = "SEQUENCES", allocationSize=1)
@GeneratedValue(generator="ID_GENERATOR")
but the generator starts with id = 1 and we have already record in the database with id 1. Is there any way we can update allocationSize to primary key generator that exists already without the initial value to be 0?

Thank you.
