Tibco spotfire analytics provides the incredibly fast and flexible environment for analyzing a critical data to help organization make a better and smarter decisions. with the powerful in-memory analysis, predictive modeling and more visual and intuitive interface, spotfire provides business and technical professionals the opportunity to quickly study data, assisting them in discovering important insights that will give them a distinct competitive edge.

3. What does options for configuring storage for process engine’s checkpoint repository?

Ans:

The options for configuring a storage for process engine’s checkpoint repository are:

Local file: In the event of an engine crash or failure, information is saved in a local file, and the same information is utilised to resume process flow once the engine is restarted. This mechanism works only in the case of single server or a load balancing approach.

Database: information is stored in the database table which is used to resume engine later. fault-tolerant engines can recover from the checkpoint only when database is used.

4. Is Tibco spotfire a core lab product?

Ans:

Tibco’s spotfire enterprise player is a product that core lab licences for usage in conjunction with our collaborative industrial initiatives.

    30. Distinguish difference between Parsed XML and Render XML?

    Ans:

    Parsed XML: Parsed XML refers to a process of interpreting or analysing the XML document’s structure and content. Parsing XML involves the reading the XML file or stream, breaking it down into its components and creating data structure in memory that represents parsed XML document.

    Rendered XML: Rendered XML refers to a process of converting the parsed XML data structure back into textual XML format. After parsing the XML and performing various operations on data, the application might need to render modified data back into XML document.

    Shared Variable:

    Scope: Shared Variable: Shared variables have the global scope within a process. They can be accessed and modified by the any activity within the process or sub-process.

    Lifetime: Shared Variable: Shared variables exist the throughout the entire duration of process execution. They are created when process starts and are destroyed when process ends.

    Job Shared Variable:

    Scope: Job Shared Variable: Job shared variables have local scope limited to the specific job or instance of a process. Every instance of a process has its own set of job shared variables.

    Lifetime: Job Shared Variable: Job shared variables exist for duration of a specific job instance. When the job starts, job shared variables are created, and are destroyed when a job ends.

    78. How does wait-notify resources work ?

    Ans:

    Basically wait and notify should share the common notification configuration which is just schema definition for a data that will be passed from notifier to waiter. A Specific instances of waiter & notifier are corrrelated by a key. For example: when one process is wait state for key ‘Order-1’, it waits till the another process issues notification with a same key value.

    79. What does default Axis in XPath ?

    Ans:

    Child axis- What this means that when select “BOOK” from a current context, it selects the child node with that name, not a sibling with that name. The Other axes are parent , self , sibling etc.

    80. What does ‘ Success if no matching condition’ transition mean ?

    Ans:

    There are three success transitions with conditions and one no success transition without conditions between two nodes N1 and N2. If none of the circumstances match, apply a ‘Success if no matching condition’ transition. Also, if there is a success transition and a success transition with a condition, and if the condition matches, both the success transition (no condition) and the transition(s) with matching conditions are followed. To avoid repeated execution pathways, use ‘Success if no matching condition’.

    81. What does Purpose of $_error variable ?

    Ans:

    $_error variable is available in node following error transition. It captures an error message, error code etc. $_error variable is not a standard or built-in variable in the most programming languages or frameworks. Its meaning and purpose, if any, would depend on specific context or programming environment you are referring to. If encountering $_error in a particular programming language or framework.

    82. What does cases where business process cant proceed correctly subsequent to restart from checkpoint ?

    Ans:

    Sending an HTTP response, verifying an email/JMS communication, and so forth. This is due to the fact that confirmation or sending an HTTP response must be done inside the same session. When the engine crashes, these sessions are terminated at the socket level. In such circumstances, send a response/confirm a checkpoint before.

    83. What does Message Selectors?

    Ans:

    Message selectors are the feature provided by message-oriented middleware systems, like Java Message Service (JMS), to allow consumers to the filter messages from a destination based on a specific criteria. Message selectors enable the subscribers to receive only those messages that match certain conditions, allowing for a more targeted and efficient message processing.

    84. How does Spotfire handle large datasets?
