PM01914: RUN MAP USING BURST WITH ECHOIN() INPUT DATA PASSES INCORRECT DATA TO SUBSEQUENT BURSTS AFTER THE FIRST BURST

APAR status

• Closed as program error.

Error description

• When a RUN map uses Burst with the input data received from an
  ECHOIN() function, incorrect data is passed to the subsequent
  bursts after the first burst.
  
  If the HANDLEIN() function is used instead of the ECHOIN()
  function, then the correct data is passed with each burst.
  
  The problem occurred when using recent WTX 8.0.1.2(249) version
  patch modules.
  
  The problem also occurs when using WTX 8.2.0.4 plus Interim Fix
  2.
  
  The problem did not occur when using previous WTX versions such
  as 8.0.0 and 8.1.0.1.
  
  The incorrect data passed during the testing appears to be the
  correct number of bytes but the data is all NULL characters.
  

Local fix

• WTXCQ - WTX00032677
  GM / GM
  Circumvention: The problem can be avoided by the following:
  
  1) Use HANDLEIN() function instead of the ECHOIN() function in
  the RUN map call.
  
  2) Use Burst setting for the main map input instead of the RUN
  map input.
  

Problem summary

• Users Affected:
  Websphere Transformation Extender users calling RUN maps and
  using burst option with ECHOIN or  E cmd line overrides
  
  Problem Description:
  When burst option is used for ECHO buffers, only first burst is
  executed. If the burst fetch unit is not S, the map does not
  work correctly
  
  Platforms Affected:
  All
  

Problem conclusion

• Fixed a problem in the environment WTX layer to handle burst
  option for data passed in with ECHOIN function or Echo command
  line override on input and output
  
  Delivered in:
  8.1.0.6, 8.2.0.5, 8.3.0.1
