Defining variables for tools

You can define variables for use in tools in the tnm.properties file.

If you want to use variables in tools and do not want to hardcode them in each tool, you can define them in the tnm.properties file. You can reference the variables in any tool definition.

For example, right-click tools that launch into other applications must be configured with the server and port details of the application.

To define variables for use in tools, complete the following steps:

Back up and edit the $NMGUI_HOME/profile/etc/tnm/tnm.properties file.
Add or edit an entry similar to the following example:
```
tnm.bhm.server=myserver.mydomain.com
tnm.bhm.port=40443
```
Note: Variables must begin with the string tnm. in the tnm.properties file.
In the tool definition XML file, reference these variables as in the following example:
```
url="https://{%prop:tnm.bhm.server}:{%prop:tnm.bhm.port}/rest_of_url" 
```
