If I understand correctly, in order to generate table ids on Oracle, the hibernate-generated DDL specifies one single sequence : create sequence hibernate_sequence; That means that successive values for, say, deployed processes JBPM_PROCESSDEFINITION can be as far away from each other as 1 from 15000 (given that the same sequence generator is used for the lines in the JBPM_LOG table too) Do you feel that this is not a problem, is there a way to work around it or is it simply my imperfect configuring & compiling the current CVS ?
