There are various ways in which a component can be configured and launched, one of the ways being Manual Launch. To change a component's Launch Mode, click the component first and then change the Execution Type to 'Manual' in the Execution tab of Properties window.

Figure 1: Choosing 'Manual' Execution Type

Manual launch is a mode in which the Fiorano peer server does not control the launch and stop of components. 

Scriptgen Tool

Manual launch can be achieved via a launch script that can be generated via the Fiorano Studio. The scriptgen tool is present at the location <fiorano_install_dir>/esb/tools/scriptgen

To generate a Manual Launch Script from the Fiorano Studio

1. Right-click the component, go to Execution option, select Save Manual Launch Script option and save the script in the component_properties folder that gets created automatically.

   These properties are used to launch the component using the scriptgen tool.

   The instruction says, "Execute scriptgen.sh/scriptgen.bat from $FIORANO_HOME\esb\tools\scriptgen directory"

3. Executing the scriptgen.bat file (on Windows platform) or scriptgen.sh file (UNIX platform) sets the environment variables. In UNIX, type the command ant and press Enter to start the Launch Configuration UI (Figure 5) to configure the launch script saved above. Perform the following actions in the Launch Configuration dialog box:

   1. Click the ellipsis  button present under the Properties File text box and choose the properties file that was saved previously (Step 1); the path appears in the text box.

   2. Click the Load button to set the appropriate properties; values as saved in the properties file appear in the Launch Configuration window.

   3. Click OK to launch the component.

   Components that has Manual execution type will not be launched when the application is launched, since they need to be started manually, as described earlier.
