APAR status

• Closed as program error.

Error description

• PROBLEM: Nesting RCG inside RCG definition causes plan extension
  to fail with Broken Pipe error on DB connection.
  
  Sample Scenario:
  Create these RCG, and then add the rcg badrcg  to a schedule..
  
  RUNCYCLEGROUP W_MON_TO_THUR DESCRIPTION "Weekly, Mondays to
  Thursdays"
  ON RUNCYCLE W_MON_TO_THU
  "FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,TU,WE,TH" SUBSET SUBSET-1 OR
  END
  
  RUNCYCLEGROUP W_SUNDAYS DESCRIPTION "Weekly, Sundays"
  ON RUNCYCLE RC1 "FREQ=WEEKLY;INTERVAL=1;BYDAY=SU" SUBSET
  SUBSET-1 OR
  END
  
  RUNCYCLEGROUP badrcg DESCRIPTION "creates bad rcg"
  ON RUNCYCLE RC1 $RCG W_MON_TO_THUR SUBSET SUBSET-1 OR
  ON RUNCYCLE RC2 $RCG W_SUNDAYS SUBSET SUBSET-1 OR
  END
  
  composer "di rcg=badrcg". returns this...
  
  RUNCYCLEGROUP BADRCG DESCRIPTION "creates bad rcg"
  ON RUNCYCLE RC1 SUBSET SUBSET-1 OR
  ON RUNCYCLE RC2 SUBSET SUBSET-1 OR
  END
  
  Use BADRCG into Jobstream
  
  
  NOTE:
  
  Creating  definitions using composer is successful.
  Using DWC will prompt an error.
  
  
  Composer will be reviewed if it is possible to prevent such
  scenario without compromising IWS performance.
  
  This limitation on RCG will be added in the IWS documentation.
  

Local fix

• Prevent using nested RCG.
  

Problem summary

•  see apar description
  

Problem conclusion

•  this apar will be 10.1 fp4 and 10.2 fp1
  

Temporary fix
