I am new to hibernate and i just started using seqhilo for ID generation for my application. I understood how the seqhilo works.
Am trying to use the seqhilo in a cluster environment. Here is my seqhilo usage details

<generator class="seqhilo">
<param name="sequence">SEQ_EWPGUID</param>
<param name="max_lo">100</param>
</generator>

I tested this on cluster, it seems to works fine but i did not understand how actually both the managed servers on the clusters get along in sequence ?

Also if i have a stand alone client which inserts data into same table without using Hibernate will it cause the problem like constraint violation in long run ?
