  • Operates Across All Major Enterprise Computing Platforms Delivers cross-platform compatibility across desktop, server, midrange, and mainframe environments.
  • Error Reporting for Attended & Unattended Operations Reports errors either to the standard Windows Event Log or through integration of SNMP (Simple Network Management Protocol) with leading data center management applications.

Application Integration

With Application Integration, data can be streamed directly in and out of applications. Without Application Integration, the zip file would be extracted and written to disk as a data file before it can be read by an application. Using Application Integration, this step is eliminated, improving operational efficiency by reducing the number of steps needed to process data.
