Overview of DSNM
•
Format responses to DSNM commands for the NetCommand requester process.
•
Send display set information to NetStatus.
•
Execute non-DSNM commands for NetStatus.
•
Log commands and responses.
The Distributed Systems Management Solutions (DSMS) System Management Guide
contains additional information on NetCommand components.
NetStatus
NetStatus is a full-screen interface to DSNM. NetStatus runs in a PATHMON
environment composed of:
•
A terminal start server (TERM-START-SVR), which:
•
Initiates the terminal session.
•
Retrieves information identifying the network objects to be monitored and
controlled and sends this information to the screen requester for display.
•
Allocates and deallocates NetStatus threads (consisting of a NetStatus terminal
and its associated NetStatus server class as defined in DSMS PATHWAY) when
a user enters and exits NetStatus.
•
A SCREEN COBOL screen requester, which:
•
Displays object status information, help screens, and text response screens on
the operator's terminal.
•
Passes commands to the NetStatus servers.
•
NetStatus servers (NETSTATUS-SVR), which provide status, command, page
control, response formatting, notification, and command and response logging
services for NetStatus. NetStatus servers:
•
Secure DSNM by checking each command against the user environment.
•
Parse DSNM commands into tokenized form.
•
Send control and status commands to and receive responses from the DSNM
command server.
•
Deliver object state change information forwarded by the command server to the
designated screen requester for display.
•
Send TACL commands to NetCommand.
