PI22221: FILE CORRUPTION USING THE WTX FTP ADAPTER

APAR status

• Closed as program error.

Error description

• Duplicate temporary files names causes file corruption when
  using the WTX FTP Adapter.
  

Local fix

• WTXCQ - WTX00045210
  GK / EJ
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender WTX FTP Adapter users on UNIX
  that are invoking many times FTP adapter in a multi-threaded
  environment.
  
  Problem Description:
  The WTX FTP adapter runs the risk of re-using temporary file
  names after "TMP_MAX" iterations
  
  Platforms Affected:
  Aix, HPUX, Solaris, Linux
  

Problem conclusion

• Problem Conclusion:
  The WTX FTP adapter on UNIX ensures that temporary file names
  that store FTP content remain unique in a multi-threaded
  environment.  Before this fix, after the "TMP_MAX" value is
  exceeded, unique file names are not guaranteed.  The latest code
  changes will test for uniqueness and if not unique continue to
  retry finding a unique file name that can be used to store FTP
  content before getting transmitted to the FTP server.
