Some of the TIBCO Interview questions I have already discussed in my TIBCO command series. Here is the list of TIBCO interview question, I am not putting answer for these interview questions right now but will put together in some other post but these questions are really great in terms of any Tibco messaging interview.
TIBCO Rendezvous Interview Questions
For better organization and quick access, I have divided TIBCO Interview questions into various categories like TIBCO Rendezvous Interview questions, TIBCO EMS Interview questions, TIBCO Certified Messaging questions, TIBCO Hawk Interview questions, and Miscellaneous TIBCO Interview questions. Please let me know if you want some more categories.

hi all,
Can you please post latest interview questions on tibco Thanks Inadvance
Some latest questions asked to me related to Tibco rendezvous in an Interview :
Difference between TCP and UDP protocol?
Which Protocol Tibco RV uses for communication? (TRDP and PGM which is based on UDP)
Difference between TRDP and PGM protocol?
If UDP is not reliable then how does Tibco RV achieves reliable delivery using UDP protocol?
I manage to answer few of them, key is to remember sequence number and re-transmission of messages from publisher to subscribers.
What is difference between TRDP and TCP protocol? or How Tibco Rendezvous works? or How does Tibco Rendezvous delivers messages reliably?
Well TRDP is protocol over UDP, which is implemented by rvd ( rendezvous daemon). As opposed to TCP, which is pessimistic protocol and require acknowledgement for every received messages, TRDP is optimistic and only sends NAK, if it doesn't receive any particular messages. This is tracked by unique sequence number. RVD assigns unique sequence number to each outbound messages and also buffer certain number of messages for 60 seconds, to support re-transmission. If other RVD doesn't receives a message, it request for retransmission and this way TRDP gets its reliable delivery. This is much faster than TCP, but obviously less reliable. This is also how Tibco RV works, though it can also use a different proprietary protocol called PGM.
2) You have your GUI application and running on windows machine and server is running on Linux machine? How do you communicate between server and GUI?
What is the answer for thos?
