JR49014: THE WRITEDATATOFILE METHOD FAILS WHEN CALLED IN BPM V8.5 WHEN THE DATA IS LARGER THEN 1MB

Version 8.5 Refresh Pack 5 for the IBM Business Process Manager products
Version 8.5.0 Fix Pack 2 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• The customer has a BPD running on v8.5. They have a coach which
  uses the Document Attachment control to "upload" a file from a
  URL or from the local file directory. Then they have a
  subsequent JavaScript activity that is attempting to write that
  file locally using writeDataToFile . When the file is less than
  1024K / 1Mb (1 megabyte) in size, the Java script works, but
  when the file is
  larger then 1024K the script fails.
  The error likely contains a message such as: "Internal Script
  error: com.lombardisoftware.core.TeamWorksException: Caught
  exception while trying to write data to file"
  

Local fix

• If DB2 is the database used, in some cases but not all, setting
  the following JDBC driver  properties were found to get past
  this issue:
  - progressiveStreaming=2
  - fullyMaterializedLobData=true
  

Problem summary

• When writing data to the embedded ECM system via JavaScript API
  writeDataToFile, this fails for data larger than 1024 kb with
  an exception.
  
  PROBLEM DETAILED DESCRIPTION:
  Actually there was a limitation in the embedded ECM system that
  has limited the size of data that can be uploaded to 1024 kb.
  

Problem conclusion

• With this interim fix the limitation of the embedded ECM system
  will be lifted so that the limitation of 1024 kb does no longer
  exist.
