JR44216: ISD DS Handler does not handle pipe status -99 when reading a row of data.

IBM InfoSphere Information Server, Version 9.1 Fix Pack 1

APAR status

• Closed as program error.

Error description

• When the ISD DS Handler reads a row from the shared pipe, status
  is returned.  In the case where the expected number of columns
  does not match the actual number of columns for the row, a
  status of -99 is returned.  The handler does not recognize this
  status and continues attempting to read from the pipe.  However,
  the same -99 status is returned and the handler loops until the
  job is manually stopped.
  

Local fix

• This symptom is indicative of a job design that includes a
  shared container that has a subset of its columns mapped
  directly to an ISD Output stage.  To correct the issue the job
  must be changed, either removing the unmapped columns from the
  shared container or insert a copy stage between the shared
  container and the ISD Output stage.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users that create an ISD service using a job with a shared
  container mapped directly to an ISD output stage but with only a
  subset of the columns contained in the mapping.
  ****************************************************************
  PROBLEM DESCRIPTION:
  This creates a mismatch in expected columns versus actual
  columns when a row of data is read from the ISD output stage
  generating status -99.  Status -99 is not handled by the code
  and it continues to attempt to read a row of data and loops
  until the job is manually stopped.
  ****************************************************************
  RECOMMENDATION:
  The code change in patch_JR44216_ISD_all_8700 detects the -99
  status and aborts the job.  To correct the issue, the job must
  be changed, either by removing the unmapped columns from the
  shared container or by inserting a copy stage between the shared
  container and the ISD Output stage.
  ****************************************************************
  

Problem conclusion

• The job must be changed, either by removing the unmapped columns
  from the shared container or by inserting a copy stage between
  the shared container and the ISD Output stage.
