Application Services supports authoring in Bash or BeanShell script for a Linux-based application and authoring in Windows CMD, PowerShell, or BeanShell scripts for a Windows-based application.

To select the appropriate action script type for a life cycle stage, in the blueprint canvas, double-click the Script Type column and select the script from the drop-down menu. For a custom task script, select one or more operating systems. You can set supported scripts from the drop-down menu.

Depending on the script type you select, you can author code and access the relevant properties through the variables in the script. For an action script of a life cycle stage, you can also use different script types in the same operating system family for each life cycle in the same component. For example, you can use the Windows CMD script for the INSTALL stage and a PowerShell script for the CONFIGURE stage. See Types of Properties.

When you author an action script, the exit and return codes vary between script types. The application architect should set proper exit codes in the script that are applicable to the application deployment. If the script lacks exit and return codes, the last command that ran in the script becomes the exit status. See Understanding the Deployment and Update Process.

Table 1. Action Script Exit and Return Codes

Script Type

Description

Bash

You can use return 0 or exit 0 codes in action scripts to indicate success status. To indicate error status, you can use return non-zero or exit non-zero.

Windows CMD

Do not use exit 0 and exit non-zero codes in the action script. If you use these codes in the script, the computed properties task processing is stopped prematurely. Use exit /b 0 to indicate success status and exit /b non-zero for error status.

Windows PowerShell

You can use exit 0 to indicate success status and exit non-zero for error status.

BeanShell

You can use System.exit(0); to indicate success status and System.exit(1);/non-zero for error status.

When you use Windows PowerShell to author a script, you cannot use the warning, verbose, debug, and host calls in an action script.
