Building custom installation services
An installation service is created by default when you create a new process application and is used when install a snapshot.
You can customize the service to handle advanced requirements in your target environment.
Ensure that you have write access to the process application that you want to install. See Managing access to the Process Center for more information about granting access to process applications.
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.
