Scheduling synchronization of templates

By default, the latest StoryTeller template version stored in the runtime repository is copied to the web content repository when a StreamStudio user logs in and accesses the Composition Center landing page.

Thereafter, synchronization is performed according to the value specified in the applicationDomainDispatcherTriggerBean property in the docdef.xml

For example, if you use Tomcat, this file is located in:

<Tomcat installation>\
webapps\ROOT\<portal_name>\WEB_INF\apps\CorrMan\spring

The default synchronization interval is 2 minutes. When the user session stops, for example by logging out, the synchronization stops within the current application domain.

Better control of synchronization

It can be useful to get better control of the synchronization. For example, you need to deploy a new template version but do not want this version to be used in Composition Center until a given time. Or, you do not want to depend on a Composition Center user logging in for the synchronization to be triggered.

To achieve this, you can create a Task Scheduler task that triggers the synchronization. This task is configured per application domain, i.e. you can have a specific different synchronization interval for a specific application domain. The default synchronization specified in the docdef.xml is automatically stopped for this domain.

In addition, logging of the synchronization is more visual through standard StreamServe logging (e.g. via Control Center) when you use the Task Scheduler.

Note:

If you want detailed data on the template synchronization result, you must check the Java application server logs.

 

For increased control, we recommend that you always use the Task Scheduler and specify to never start the Java application server scheduler: 1 Open the schedulers.properties file in a text editor. For Tomcat, it is located in the following directory: <Tomcat installation>\ webapps\<portal_name>\WEB_INF\spring\properties 2 Specify templatesynch.local.enabled=false

You can add Task Scheduler applications on your local host, or on remote hosts that are part of the site. The remote host must be configured to use the StreamServe Enterprise Repository that the site is connected to.

Note:

Only configure one template synchronization task per Task Scheduler application.

Post requisites

•	To be able to start a Task Scheduler application and run the scheduled tasks, a runtime repository must be created for the application domain.

•	A StreamStudio web application must be created in Control Center.

For information on how to create and deploy a StreamStudio application, see Deploying a web application

Note:

StreamStudio with its profile configurations must be linked to the application domain hosting the Task Scheduler.

•	You must configure StreamStudio as a web service profile. This is to enable the Task Scheduler application to connect to the Java application server (e.g. Tomcat) which performs the actual synchronization between the repositories.

See To set up a StreamStudio web service profile.

•	An authentication profile for a StreamStudio user must be defined for the StreamStudio web service profile. You can create this profile in Control Center. For security reasons, you can set up a security profile that enables connection over SSL or TLS.

See To set up an authentication profile for a StreamStudio portal.

For more information, see the Profile configurations documentation.

 

To add and configure a Task Scheduler

1	Right-click the application domain and select New Application. The New Application dialog box opens.

2	From the Application type drop-down list, select Task Scheduler <version>.

3	Configure the application properties.

Note:

You cannot use the name Task Scheduler if you run the application on a Windows host, since this name is used by a Windows service.

4	Click OK. The Task Scheduler application is added to the application domain and the Configuration dialog box opens.

5	Specify the application log level.

6	Click in the value field for the Tasks property and click the browse button.

7	In the Service Configuration dialog, select Template synchronization from the drop-down list and click Add.

8	Configure the task. For more information, see:

–	Configuration dialog box (Task Scheduler)

–	Service Configuration dialog box (Task Scheduler)

–	Scheduler Configuration dialog box

To add and configure a Task Scheduler on a remote host

1	Right-click the application domain and select New Application. The New Application dialog box opens.

2	From the Application host drop-down list, select Show all. All the hosts in the site are displayed.

3	Select the host for the application.

4	Configure the application properties.

Note:

You cannot use the name Task Scheduler if you run the application on a Windows host, since this name is used by a Windows service.

5	Click OK. The Connect dialog box opens.

6	Enter the user name and password for a management gateway user and click OK. The remote host and Task Scheduler application are added to the tree view and the Configuration dialog box opens.

7	Configure the application log level and the scheduled tasks.

To set up a StreamStudio web service profile

1	In Control Center, double-click the StreamStudio web application linked to the application domain hosting the Task Scheduler application.

2	In the StreamStudio configuration - Profile Configuration Editor dialog, configure the web service.

For more information, see the StreamStudio connection profiles in the Profile configurations documentation.

3	Save the configuration.

To set up an authentication profile for a StreamStudio portal

1	In Control Center, double-click the StreamStudio web application linked to the application domain hosting the Task Scheduler application.

2	In the StreamStudio Configuration dialog, select the Authentication profile property.

3	From the Authentication profile drop-down list, select <Create new...>.

4	Specify the user name and password of the application domain administrator that has been set up in the application domain editor.

5	Optionally, configure a Secure channel profile.

6	Save the configuration.
