SEP - Service Execution Processes

Service execution process. The name is taken from native Enterprise Server. In Enterprise Server for .NET, a SEP is an AppDomain running within a w3wp.exe or seesep.exe process. Multiple SEPs will exist within these processes. A CICS transaction or batch job runs within a SEP.
A SEP provides:
  • A COBOL execution environment
  • State/Session management
  • Transactional control (resource management)
  • Infrastructure for RTS and Request Handlers
