Remote Maintenance of the MICROS Retail OSCAR POS system

It is generally possible to access another computer via DTM. There are some Requirements, though, that have to be met on both the side of the hotline computer and the customer’s computer. These preconditions will be pointed out in the first step. In the second step, you will be informed about how to establish a Connection. Some Examples will illustrate the process.

Requirements (ADS Hotline)

• UNIX OpenServer V
• MICROS Retail OSCAR POS installation
• The establishment of a connection must be started from the task on which the graphical user interface is active, this would normally be Task 2.
• You have to be signed on at this task as oscar.
• The name of the customer’s computer must be known and entered in the file /etc/hosts.
• The TCP/IP address of the customer’s computer must be known and entered in the file /etc/hosts.
• Make sure the screen solutions are equivalent. This will allow you to work with actually all of the screen masks of the other computer.

Requirements (Customer’s Computer)

• UNIX OpenServer V
• MICROS Retail OSCAR POS installation
• In the file /.rhosts, the hotline computer’s name must be entered. The input must be made at the customer’s location.
• In the file /etc/hosts, the hotline computer’s name must be entered. The input must be made at the customer’s location.
• The TCP/IP address of the hotline computer must be known and entered in the file /etc/hosts.
• A DTM-/Hotline administration terminal must be established. The set-up must take place at the customer’s location.

Establishing / finishing the connection

In order to be able to  establish a connection to and work with a remote installation, you have to proceed as follows:

1. Establish connection client -> database of a remote installation
• The access to a foreign / customer’s computer is only available after establishing a connection to this computer. The connection is to be established via the following command:

oscar client -S HOSTNAME -i INSTALLNO

• Explanation:
  HOSTNAME= Name or IP address of the remote computer.
  INSTALLNO = Number of the installation, in which the hotline computer has been configured in the remote computer (System -> Configuration -> Process Unit).

• The establishment of the connection will be displayed with the screen message "Starting online".
• As soon as the dispatch of the MICROS Retail OSCAR POS application is displayed, you have accessed the remote computer.
  Carry out the maintenance tasks.

1. Finish the connection
• Finish the connection by clicking on the “End” button in the dispatcher.

Examples:

• Working with a system unit that belongs to the installation 112:
• oscar client -S zentral -i 112
  -> # connects to the database of the computer "zentral" and the installation 112
• oscar client -S bar -i 1121
  -> # connects to the database of the computer "bar" and the installation 1121
• oscar client -S bistro -i 1122
  -> # connects to the database of the computer "bistro" and the installation 1122
• oscar client -S cafe -i 1123
  -> # connects to the database of the computer "cafe" and the installation 1123
