File Monitor

File Monitor

The file monitor batch script is purposefully designed to wait for files in a folder before subsequent downstream processes are started. This is useful in integration applications where there are dependencies on such files or resources to be present before those processes ca n be initialised.

Rem Desc   : This script when activated waits for files in a folder to be present. When  the specified is available it then proceeds to start a SQL Agent job to kick subsequent processes.
