Communication is performed via a series of Web Service calls. These are simply portals to call the process parts to run. If this is made as simple as possible, these simply start the process parts, and fail only if they cannot.
Remote Web Service Calls
Method | Description |
|---|---|
Remote1Start | To start the Replication process on the REMOTE System, this tells the REMOTE System to get the non-static data. |
Remote2Start | To tell the REMOTE System that the Transmission file is on the Remote System and to begin processing it. |
RemoteStop | To tell the REMOTE System to cancel the current Replication process. |
Local Web Service Calls
Method | Description |
|---|---|
Local2Start | To tell the LOCAL System that the data is available. |
Local3Start | To tell the LOCAL System that the update has completed successfully. |
LocalStop | To tell the LOCAL System that an error occurred. |
General Web Services Calls
Method | Description |
|---|---|
GetProcessStatus | To get the status for a location. |
ShowVersion | To get the version of the running software. |
Web Service Configuration
The Web service has a number of configuration settings. It requires to know where Python is installed and where the Python scripts that form the ‘Entities’ are located.
| Code Block | ||||
|---|---|---|---|---|
| ||||
<appSettings>
<!-- Where to find Python -->
<add key="PythonDir" value="C:\Python25" />
<!-- Where to find the scripts for the project -->
<add key="ScriptDir" value="F:\Python\Source\Replication" /> |
The service itself can be configured to accept only calls for one or other of the ‘Entities’. By setting the value to True or False, you can enable whether these calls are allowed.
| Code Block | ||||
|---|---|---|---|---|
| ||||
<add key="AllowRemote" value="True" />
<add key="AllowLocal" value="False" /> |
| Note |
|---|
You can place a side into Test mode by setting this value to Test. In this mode, the service checks the parameters and reports back that the ‘Entity’ in question has successfully started, without actually starting anything. This is useful for testing purposes. |
