Error description

  • Error Message: There were outages seen in e-commerce site and
    the application took around a minute to respond.
    .
    Stack Trace: None
    .
    The customer saw tens of thousands of the following -
    org.omg.CORBA.BAD_OPERATION: The delegate has not been set!
    vmcid: 0x0  minor code: 0  completed: No
    in the ORB logs, within few minutes.
    

Local fix

Problem summary

  • The problem is a result of the tens of thousands of
    BAD_OPERATION exception objects being created when the tie and
    stub are loaded for the first time.
    

Problem conclusion

  • This defect will be fixed in:
    5.0.0 SR12 FP5
    .
    The solution is to use
    reflection to access the delegate of the
    tie & stubs and avoid the creation of BAD_OPERATION exception
    objects. Also, the delegate value will be cached for future
    usage.
    

Temporary fix
