Building custom installation services
An installation service is created by default when you create a new process application and is used when you install a snapshot. You can customize the service to handle advanced requirements in your target environment.
Before you begin
About this task
You can add calls and scripts to the installation
service to perform specific functions when a process application is
installed on a process server in another environment. The following
list contains some of the tasks that a custom installation service
might handle.
- Create or update database tables
- Update necessary environment variables
- Determine which snapshots are already installed
- Migrate individual process instances
- Create custom time schedules
For example, you can customize an installation service to create tables on the target process server to hold data such as the options for drop-down menus that exist in your process. When you need to add to or change those menu options, you can modify the service so that those database updates are handled automatically during installation.
Procedure
To add functionality to an installation service, perform the following steps.
- Open the process application in Process Designer.
- From the Setup category, open the installation service.
- In the diagram that opens, add the service calls and scripts that you need for your particular installation.
- Save your changes.
