Once the setup is done, the most important thing is to monitor the connections, communication, transfer of messages and to troubleshoot the issues. This can be done through the means listed below. Monitoring and Troubleshooting: Below are the means available for monitoring and assessment: Rendezvous performance assessment software: It is a tool that measures the performance of RV in a running situation and provides a detailed output report. It consists of two executable programs: Rvperfm and rvperfs : These are the performance assessment tools which measures their capacity to receive messages as part of overall network performance. Rvperfm sends messages to the network and reports the statistics to stdout. Rvperfs listens for messages from rvperfm, gathers and reports statistics to rvperfm at the end of each run. Latency assessment software (rvlat): It is a latency assessment tool that measures the message latency that is the total time taken to send a m...

Virtual Circuit: Virtual circuit (VC) provides exclusive communication between two nodes. Only the two nodes can communicate with each other. The sender can only send messages to opposite node and the receiver can receive messages only from the opposite node. If there is a requirement where transport should be done among specific nodes and no other listener should get the information then VC should be used. Fault Tolerance: When the active program fails, the fault tolerance software directs one of the backup programs to become active and start processing. To configure programs in FT mode below parameters must be configured: Active Goal: It defines the total  number of active members. For example: If the active goal is set as 4, there will be 4 active members those have the highest ranks among all the members. Rank: Each program has a unique rank. If a program has N rank and another program has N+1 rank, then N is a higher rank than N+1. It determines the membe...

Transport: It is the mechanism for sending and delivering messages. There are three main parameters in Tibco RV for transport: network, daemon and service. Service is specific to programs. Multiple programs may be running on a network. Each program has a different service. There can be many services running under a daemon for different programs. Network parameter specifies the interface for multicast communication from a program. A specific network should be selected for  outbound multicast Rendezvous communications. Daemon specifies the port where RV daemon runs. RV communicates through this daemon and hence remote daemon must be specified to support network communications. Tibrvsend and Tibrvlisten: Every Tibco RV installation provides these two utilities for sending and receiving messages on any multicast network. Sample for testing these utilities: tibrvlisten.exe -service 7576 -network 10.21.6.38 -daemon tcp:7500 "TEST" tibrvsend.exe -s...

Features of Tibco RV: Decoupling and Data Independence : In RV the applications are loosely coupled and RV has self-describing data that makes it easy for the applications to share data. Location Transparency : RV is based upon subject based addressing. The data/messages are sent and received over subject; hence the programs can communicate without knowing the network details. Architectural Emphasis on Information Sources and Destinations : RV provides efficient solutions for developing distributed system by emphasis on identifying sources and destinations of information. Reliable Delivery: RV provides reliable delivery of messages and without the need of network details. The information like network details and packet transfer are hidden. Certified Message Delivery: Some applications require more assurance for message delivery. For this RV provides Certified Message (CM) delivery which sends the confirmation for the messages received. Distribu...

When I started working on Tibco RV, I used to get stuck on many things. Small, big but the main problem was that I couldn’t find much online as a resolution. Information was limited and distributed. So here’s my try to bring all that I know to one place about RV and provide solutions to as many issues as possible. Intro: For large enterprises, the most fundamental need is the data transfer from one system to another. The messaging model used must be efficient, reliable and scalable. Tibco RV is used by applications running on distributed platforms to exchange data for Enterprise Application Integration (EAI). Tibco Rendezvous has more than 2000 customer installations and is the leading messaging system for real-time and broad data distribution.  Tibco RV is used in Replay Service, Reuters Wireless Delivery System, Reuters Market Data System and Internet Finance Platform. Tibco RV is used by distributed applications for communicating data. It provides both point-to-...
