Creating a Global Variable

Integration Server 10.15 | Integration Server Administrator's Guide | Managing Services | Managing Global Variables | Creating a Global Variable

You can create global variables using Integration Server Administrator. The location where Integration Server saves a global variable depends on whether it is a server level or package level global variable.

For server-level global variables, the variable definition is saved in:

Integration Server_directory\instances\instance_name\config\globalVariables.cnf

For package-level global variables, the variable definition is saved in the package in:

Integration Server_directory\instances\instance_name\packages\package_name\config\globalVariables.cnf

When you create global variables, keep the following points in mind:

Global variables can only be used to specify values for variables of type String, String List, and String Table.

Global variable names:

Cannot include any special characters except period (.) and underscore (_).

Can be of a maximum length of 255 characters.

Are case-sensitive.

Must be unique within the same scope. For example, two global variables within the same package cannot be identical. For more information on how to specify the global variable that a service should use, see webMethods Service Development Help.

If the global variable you are creating is a password, Integration Server encrypts and saves it using OPE (outbound password encryption).

Global variable value can be of a maximum length of 255 characters.

When editing a global variable, you can modify only the Value field.

Global variables can have empty values.

Global variables must be identical on all Integration Servers in a cluster.

You can deploy global variables by using webMethods Deployer. For information about using Deployer, see the webMethods Deployer User’s Guide.

You can use global variable substitution when debugging a service.

To create a global variable

1. Open Integration Server Administrator.

2. Go to Settings > Global variables.

3. Click Add Global Variable.

4. Under Global Variable provide the following information:

Parameter	Specify
Is Password?	Whether the global variable you are defining is a password. If the Is Password check box is selected, the text that you enter in the Value field is entered as a password, with asterisks indicating the input instead of characters. Integration Server encrypts and saves the text that you enter in the Value field as an outbound password.
Package	A package to which you save the global variable definition. If you specify a package, Integration Server creates a package-level global variable. If you do not specify a package, Integration Server creates a server-level global variable.
Key	A name for the global variable. Integration Server uses this key to refer to the global variable while performing global variable substitution.
Value	Value for the global variable.

5. Click Save Changes.
