Which of the following activities are process starter?
-
File Poller
-
RV Subscriber
-
HTTP Receiver
-
All of these
File Poller, RV (Rendezvous) Subscriber, and HTTP Receiver are all examples of Process Starter activities in TIBCO BusinessWorks. Process starters initiate process execution based on external events (file arrival, RV message, HTTP request). 'All of these' is the correct answer.
To answer this question, we need to understand what a process starter is in the context of activities.
A process starter is an activity that initiates the execution of a process or workflow. It triggers the start of a process when a specific event or condition is met.
Let's go through each option to determine if it is a process starter:
Option A) File Poller - A File Poller is an activity that monitors a specific directory for the presence of new files. It can be configured to start a process when a new file is detected. Therefore, File Poller is a process starter.
Option B) RV Subscriber - An RV Subscriber is an activity that subscribes to a specific event or message on an RV (Rendezvous) messaging system. It can be configured to start a process when the subscribed event or message is received. Therefore, RV Subscriber is a process starter.
Option C) HTTP Receiver - An HTTP Receiver is an activity that listens for incoming HTTP requests. It can be configured to start a process when an HTTP request is received. Therefore, HTTP Receiver is a process starter.
Based on the explanations above, all of the options (A, B, and C) are process starters. Therefore, the correct answer is option D) All of these.
