Error description

  • EclipseLink generates preallocated sequence values at NEXTVAL
    - allocationSize. This strategy causes an incompatibility with
    other jpa providers, namely OpenJPA, that expects ID values to
    be beyond NEXTVAL. This PMR provides an enhancement to
    EclipseLink in for form of a new persistence property that
    allows the behavior to change and add compatibility to
    existing tables IDs from other jpa providers.
    
    The new persistence property is this:
    <property
    name="eclipselink.sequencing.start-sequence-at-nextval"
    value="true"/>
    
    With this property set, EclipseLink will start generating
    sequence ID values from NEXTVAL forward, instead of the default
    behavior of starting at (NEXTVAL - size).
    
    Note that the default behaviour remains "as-is".
    This APAR was taken to ship this new support.
    Please read the responder page in case of changes to the final
    code behaviour.
