The Sync.wif file that exists in your application directory (for remote applications only) is the master file that contains the configuration server list and client data for a remotely configured application.
VTS automatically creates a Sync.wif file whenever a remote application is established. In other words, a Sync.wif file is automatically generated and added to the application directory by VTS when workstations have been specified in the Configuration Server Choices list of the New Application Properties dialog, and the OK button has been clicked; or when workstations have been specified in the Configuration Server Choices list of the Application Properties dialog for a formerly non-remote application, and the OK button has been clicked.
By default, Sync.wif contains one section, similar to the following example:
[Configuration-Servers]
Name = WHITE
Name = SMITH
Name = TAYLOR
The first server appearing under the [Configuration-Servers] section is the primary configuration server for the application, while the subsequent servers are the backup configuration servers for the application (see Primary Configuration Server for details on primary and backup configuration servers). This list is configured using the Configuration Server Choices section of either the New Application Properties dialog (for a new application), or the Application Properties dialog (for an existing application).
A second, optional section can be added to the Sync.wif file. An example is shown below:
[Configuration-Clients]
Name = MCNEIL
Name = APPLIN
Name = SHANNON
If you add a [Configuration-Clients] section to the Sync.wif configuration file for your application, and list workstations by name under the section, these will be the only workstations permitted to retrieve a copy of this application (using the Get From Server functionality of the VAM). Any workstations that do not appear in the [Configuration-Clients] list will be prohibited from accessing to the application.
Note: It is strongly recommended that you use workstation names other than IP addresses when specifying configuration servers or service servers, especially in networks where the workstations may be dual-homed, or where dynamic IPs are assigned.
