Explain what is TIBCO Spotfire?
Spotfire Enterprise Player, when combined with Core Lab’s RAPID database, allows our clients to perform analytics on the data sets being generated in our Joint Industry Projects. Each active Joint Industry Project has a Spotfire Analytical Template associated with it which allows our clients to investigate the various data sets through tabular and graphical displays. Each display can be filtered by a wide variety of data types stored in our RAPID database such as formation, country, geologic basin, porosity, permeability, geochemistry parameters, etc. Spotfire is extremely easy to use and provides a powerful resource in reservoir evaluation.
Is TIBCO Spotfire a Core Lab product?
The Spotfire Enterprise Player is a product of TIBCO, which Core Lab licenses for use in conjunction with our Joint Industry Projects. The Analytical Templates themselves are a product of Core Laboratories. In order to facilitate the transfer of data from our RAPID database to our Spotfire Analytical Templates, Core Lab developed RAPIDLink which automatically delivers all data to which a client is entitled.

Can we have backward transitions in TIBCO BW Processes?
In TIBCO Designer Processes, transitions between activities are always uni-directional. This means that we can’t go back to a previous transition from any point.
What are different Panels of TIBCO designer window and what is the purpose of each?
There are following four types of panels available in TIBCO designer window:
Project Panel: This panel shows project hierarchy.
Design Panel: This panel is used to design new BW Processes in TIBCO.
Palette Panel: This Panel has all the available Palettes with bundled activities which can be dragged and used in design panel during process development.

What is difference between fault tolerant and Load balanced deployment in TIBCO?
Load balancing is done between two or more servers where the load is distributed between servers to avoid any server crashes due to heavy load on a single server.
Fault tolerance is achieved between two servers where one server acts as a primary and the second server acts as a secondary/backup server for the primary server. Whenever failure occurs for primary server, the backup secondary server becomes the primary server.
What are the options for configuring storage for process engine’s checkpoint repository ?
The options for configuring storage for process engine’s checkpoint repository are:
Local File: Information is stored in a local file which in case of engine crash/failure and same information is used to resume the process flow once engine is up. This mechanism works only in case of single server or load balancing approach.
Database: Information is stored in a database table which is used to resume engine later. Fault tolerant engines can recover from a checkpoint only when database is used.
