Using Global Variables
To use the global variable in the fields of a resource in TIBCO Designer, enter the variable name surrounded by %% on both sides. For example, you must enter %%UserName%% in the User Name field to use the UserName global variable.
You can also drag global variables to the fields in the Configuration panel, for example, user name and password fields.
Note: TIBCO ActiveMatrix Adapter for Database 7.2 does not support the use of nested global variables.
