New CMD Heater – executing an external script or program

This version adds another powerful function (Heater) to FlowHeater. With the new CMD Heater it is possible to not only dynamically execute external programs, but also run scripts (Perl, PHP, PowerShell, etc.) while an import/export is being run. The actual FlowHeater process will pause until the external processing is complete. Possible output from the external process can be redirected via FlowHeater Parameters for subsequent use by the FlowHeater Definition. If execution of the external program/script aborts with an error then the exit code of the task can be checked by an IF-THEN-ELSE Heater and if necessary the FlowHeater run also aborted using the Stop Heater.


Release notes for version 4.1.0 on October 2, 2017

Further changes

Stop Heater

The Stop Heater now also supports the FlowHeater Parameter and Windows system environment variables for the dynamic generation of error reporting and immediately stopping the process.


Bug fixes

  • SQL Server Adapter: problems cleared up when using slow PCs and via Remote Desktop with improved selection of databases.

  • Excel Adapter: corrections when only “update” used. Previously it aborted with an error message when attempting only to update data rows without appending in an Excel sheet where the data to replace was not found.
