When you have more than one CTPView server in your network, you can synchronize some or all of the servers to the same configuration. You must designate one server as the primary server and the others as secondary servers. When you add a secondary server, the primary server sets up SSH authorization keys with the secondary server so it can communicate without requiring the login password again. The server configuration settings apply only to the server you are logged in to. These settings do not affect the other CTPView servers in the network.
The primary server has a 15-second period to establish contact with a remote CTP platform. If the period times out, the primary server skips to the next remote CTP platform and continues executing the program. This information is displayed in the screen output and logs. When you add a new remote CTP platform to a primary server, the new platform’s SSH RSA keys are also exchanged with each secondary server. You can disable this feature in the Administrative Functions pane when you add the new remote platform.
The following definitions are restricted in scope to the server that you are logged in to. Each server maintains its own file of server designations that it refers to when performing a server synchronization. You do not need to configure settings on a remote secondary server for that server to be updated by the primary server that is performing the synchronization.
![]() | Note: Server synchronization is supported only on CTPView 1.4.2 or higher releases. |
You must identify a primary server and one or more secondary servers as members of a synchronization network.
To configure your synchronization network:
The Administrative Functions pane is displayed.
The Server Synchronization pane is displayed.
The primary server information is displayed in the Current Server Synchronization Settings table. The server name is used for display purposes only and does not need to be the server's UNIX hostname.
The primary server must be the server you are currently logged in to.
To add this server back to the synchronization network, select Secondary Server for the server type.
The server is deleted from the table. If you later want this server to be part of the synchronization network, you must add it back to the table.
If you want to restore the original settings in the table, click Reset instead of Commit Changes.
To automatically synchronize your network:
The CTPView Automatic Functions pane is displayed.
When the secondary servers and the CTP platforms are synchronized, the CTPView software copies the necessary SSH keys to each secondary server so that it can communicate with the CTP platforms without requiring the login password to be entered. When only the secondary servers are synchronized, only server-specific information Is synchronized.
The optimal configuration runs the synchronization shortly after the statistical data is obtained from the CTP platforms. The numbers you select represent a specific time, not an interval of time. For example, the default setting of [0,1,ANY,ANY,ANY] means that synchronization occurs at the 0 minute (on the hour) of the first hour (1 AM) every day (any day of any month, landing on any day of the week). A setting of [30,16,8,ANY,ANY] causes the synchronization to occur at 4:30 PM on the 8th of every month.
If you decide not to add the entry, click Reset.
To have the same function performed at different times, add a new entry for that operation for each time.
To manually synchronize your network:
The Synchronize Secondary Servers window is displayed.
You can select more than one platform by holding down the Ctrl key when you click the platform names. Alternatively, you can click Select All Hosts to select all the listed CTP platforms.
