| Different types of variables in TIBCO and provide details?
TIBCO has mainly three types of variables as given below with some details:-
(1)Global Variables:-As the name suggest Global variable usually these are some common variables which are used in whole projects just like we specify the constants variables throughout the project. And these constants can be changed and specified while we are doing testing or designing our projects. We can also specify different values for each deployment of our project. For example in tibco we specify two global variable that are Machine IP and Port which can be later changed at the time of deployment with change in code.
(2)Process Variables:-Process Variables allow us to access project various data. To understand this we will take a example of project where many predefined variable are situated and these variables contained the Process ID, Project Name and some other information. And we can also create user define process variable for containing process-specific data. Process variables are data structures available to the activities in the process. Process variables are displayed in the Process Data panel of each activitys Input tab.
(3)Shared Variables:-When we need some variable to access on across multiple process instance then shared variables comes into picture. Because multiple process instances can access the same variable, we can also synchronize access across processes when setting or retrieving the shared variable.
There are two types of shared variables:
(1)Shared Variable
(2)Job Shared Variable | | |
