IT24753: FILE NODE PERFORMANCE ISSUE IF THE INPUT FOLDER HAS LARGE NUMBEROF FILES.

APAR status

• Closed as program error.

Error description

• In the case of FileInput and FileRead nodes, pattern matching is
  done against each file present in the input folder even if the
  input file name is provided without any wildcard characters.
  This pattern matching can result in a severe
  performance issue if the input directory contains a large number
  of files.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM App Connect Enterprise V11.0 and IBM
  Integration Bus V10.0 using the File Nodes.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  In the case of FileInput and FileRead nodes, to identify the
  file to process from the input directory a pattern matching is
  done against each file present in the input folder even if the
  input file name is provided without any wildcard characters.
  This excessive pattern matching can result in a severe
  performance issue if the input directory contains a large number
  of files.
  

Problem conclusion

• The product now directly checks the existence of the input file
  in the input folder and if it found then avoids carrying out the
  pattern matching against each file present in the folder.
