Error description

  • Unable to deploy multiple snapshots containing the same BPEL
    processes due to comparemerge errors.
    
    The first snapshot of a process app containing BPEL processes
    can be deployed. But when deploying further snapshots the BPEL
    install step fails during the compare merge functionality. This
    generally only affects BPELs which have interface WSDLs which
    make use of importing other XSD files.
    
    There are various errors that can occur which would be similar
    to these and would be seen on in the app cluster logs after the
    deployment:

    This is related to APARs JR44412 and JR46572. JR46572 is need
    with this to resolve the issues. This fix supercedes JR44412.
    

Local fix

Problem summary

  • When activating a new version of a process application the
    differences between the different versions of the BPEL
    artifacts (as result of the multiple installed versions) are
    calculated. This calculation fails with the exception above.
    
    PROBLEM DETAILED DESCRIPTION:
    When creating multiple versions of a process application that
    contains BPEL based business processes, this can lead to an
    exception similar to this:

Problem conclusion

  • With this interim fix installed the activation of multiple
    versions of the same process application should be possible
    without problems.
