The UBIK® EnterpriseService is a Windows service that is meant to automate UBIK® interface components or interface workflows.
Concept
The EnterpriseService typically runs on a server and watches an arbitrary amount of folders in the file system for changes, like new or modified files. Once such a change occurs, it parses the file and checks if its extension matches the signature of a UBIK® command file. If true, it will be processed.
Command file
A command file for the UBIK® EnterpriseService is a plain text file and has the extension .command. When the EnterpriseService starts processing such a file, it will be parsed as an XML document, every non-XML information in the file will be ignored. A sample command file for starting an interface component looks like this:
<Commands>
<Interface FullName="UBIK.TEST, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" File="F:\Test\UBIK.TEST.dll" Class="UBIK.TestInterface" Direction="E">
<Parameter Key="Server" Value="AUGLNZ0SQL" />
<Parameter Key="InitialCatalog" Value="UBIK.Sandbox.Dev.V2" />
<Parameter Key="UserID" Value="sa" />
<Parameter Key="Password" Value="secretpassword123" />
<Parameter Key="RecordLifeTime" Value="-1" />
<Parameter Key="MyIFNeedsThis" Value="TestValue" />
</Interface>
</Commands>
</InterfaceManager>
This command file would attempt to instantiate the class UBIK.TestInterface from the assembly F:\Test\UBIK.TEST.dll. If connection succeeds, it will then invoke the the methods of the export interface, because of the setting Direction="E".
A sample command file for starting a workflow looks slightly different:
<Commands>
<Workflow Name="WF_XML_TEST" UID="5fdccb8c-85db-4dfc-861a-57be38267bfb" Async="False">
<Parameter Key="Server" Value="AUGLNZ0SQL" />
<Parameter Key="InitialCatalog" Value="UBIK.Sandbox.Dev.V2" />
<Parameter Key="UserID" Value="sa" />
<Parameter Key="Password" Value="secretpassword123" />
<Parameter Key="RecordLifeTime" Value="-1" />
<Parameter Key="MyWorkflowNeedsThis" Value="TestValue" />
</Workflow>
</Commands>
</InterfaceManager>
This command file would attempt to load the workflow object with the Guid 5fdccb8c-85db-4dfc-861a-57be38267bfb and invoke it synchronously, because of the setting Async="False".
Workflow Arguments
Every workflow started by the Enterprise Service needs an argument UBIKObject of data type UBIK.Kernel.BaseClass. The Enterprise Service initiates this default argument with the workflow object itself.
Any additional parameter, which should be passed from the command file to the workflow, has to have an equivalent workflow argument as well.
 | Configuration files can of course be created and edited manually, but they can be more comfortably created using the Interface Manager |
