Hosts Setup

The MAINVIEW Data Server can maintain connections with many host servers. Each host server is defined by its address and the TCP port number that was assigned to the host server in the started task JCL. This is the same Host Server used for MAINVIEW Explorer, with the same address and port number.

Host Setup Panel

The user can define a new host server on the Host Computers tab by filling in the fields for the list entry and clicking Apply. The address and port number for each host server can be edited from this panel. Right clicking displays a menu that allows a new host to be added or an existing host to be deleted.

Clock Source

The Clock Source column selects one of the host servers to be used as the basis for the "Host" mode of the main panel clock. Periodically the Data Server will retrieve the local time from the selected host, and compute the difference between the Data Server local time and the host time. This is used to adjust the display of host time in the clock.

Host Simulation

For purposes such as training, testing, and demonstration, the MAINVIEW Data Server includes the ability to simulate a host system. The simulated system will have only a couple of products and views available, and it will use an abbreviated interval of only five minutes so that the recording exits may be driven more frequently.

Data from a simulated system can be written to a file or an Access database on the same system allowing the whole MAINVIEW Data Server to be run on a single workstation without requiring a host system.

To define a simulated host, set the address field to "SIMULATE". The Port field can have any value. If the simulated host requires a logon, any password will be accepted except the characters "bad".
