Activating a Configuration Template 
During installation, a default configuration, which includes configuration templates, is provided to your system. You can make custom changes within the system configuration templates and also activate new templates using the Config Tool.
When you apply the new template, it applies to all Java instances in the relevant cluster.
Before changing the template, make sure your AS Java is stopped.
Start the Config Tool by double-clicking the configtool script file in <SAP_install_dir>/<system_name>/<instance_name>/j2ee/configtool directory.
Choose .
From the dialog window, choose the relevant new template.
You have three options, regarding the custom settings in your templates:
Use existing custom settings - if the new template you want to apply has been previously customized, this option applies its custom settings. If it has never been used, its default settings are applied.
Copy current custom settings - the settings of the new template are overwritten by the custom settings of the template you have currently used.
Reset custom settings - all custom settings of the new template are reset. The template applies its default configuration settings.
Note
For the last two scenarios, the Config Tool provides backup of the custom data of the new template. To activate this function, choose .
Choose OK.
Start the AS Java.
The new template is activated.
