User, application, domain, custom, and system scopes
The system scope version of this configuration variable determines the default period, in minutes, after which domain and user variables expire. For user variables, the expiry timer is reset to zero each time the user accesses Tango Server. For application variables, the expiry timer is reset each time the Tango application is accessed. For domain variables, the expiry timer is reset each time a user from the domain accesses Tango Server. For custom variables, the expiry timer is reset each time a variable in the custom scope is accessed.
Setting variableTimeout to zero indicates that variables never expire. In general, this value is appropriate for the domain scope only.
To change the expiry timeout period for domain variables only, assign the desired value to variableTimeout in domain scope. For example, to specify that domain scope variables never expire, make the following assignment:
<@ASSIGN NAME=variableTimeout SCOPE=domain VALUE=0>
Setting this variable with user scope sets the expiry timeout for the current user, overriding the value in the system scope.
Setting this variable with application scope sets the expiry timeout for Tango application, overriding the value in the system scope.
