Error description

  • Rational Business Developper V7.1.0.1:
    
    Abend AD2Z from ELACSV7 module calling remote program from the
    EGL debugger.
    
    The EGL program running in the debugger is first calling a
    generated program (or a Cobol / PL/I program) that inserts a row
    in a DB2 table.  The call is executed via a CICS Transaction
    Gateway connection running on z/OS.  The row is inserted and the
    control is, as expected, is returned to the debugger.
    
    The Logical Unit of Work used is client control so the insert is
    not yet committed.  The second call is made to a generated
    program (or Cobol / PL/I program) that reads this row from the
    same DB2 table.  This causes a deadlock and abend AD2Z from the
    ELACSV7 module is received.
    

Local fix

Problem summary

  • A new transaction was being started for each call.  That
    meant luwControl=CLIENT did not work, because uncommitted
    changes in one transaction are invisible to another
    transaction.
    

Problem conclusion

  • Transactions will now be reused when it is necessary.
    

Temporary fix
