Expedite your Tibco professional career with our recently designed HKR’s Tibco interview questions with answers. This Tibco software is one of the popular software tools, which is developed to perform major tasks such as data extraction, loading of necessary data, and transmission of data. As per the latest tech report, almost 0.6% of the software products are developed on the base of Tibco application tools. This article is specially designed for those who want to begin their career as a Tibco expert. So what you are waiting for, let’s get started our journey with this article;
Ans: Tibco is also known as The Information Bus Company, this is an information integration and analytical tool. Tibco software is developed by the company JasperSoft, located in the United States of America. This tool provides data integration, analytical, and business warehouse applications. Tibco used to manage, integrate, and monitor the business level of enterprise data. Tibco is widely used because of its flexibility, reliability, and scalability.
Ans: SQL direct executes the entire DML operations like table creation, insertion, and deletion. Whereas JDBC activities execute specific operations such as insert, modify, and update.
Ans: TRA stands for Tibco runtime Agent; this performs main two functions such as;
Ans: The below are the important revision control system options available in Tibco designer such as;
Ans: The sequence will be as follows;
Ans: Here the integration can be achieved in three different layers and the following errors will be raised;
Ans: The Tibco workflow offers various types of transactions that can be used in different situations. These different types of transactions are used in the integration process. The Tibco business workflow supports three different types of transaction such as;
Ans: The inspector activity in Tibco is used to write the output activities for all the workflow activities. This is mainly used when you debug the definitions and then you wanted to see the entire schema instead of mapping any specific elements to the write file activity data transaction.
Ans: The maximum/minimum of threads available for incoming HTTP is 75/100.
Ans: The following are the mandatory configuration parameters for FTP connection and FTP firewall;
When you enable the FTP connection, you need to add a proxy host and port.
Ans: The 4 main panels of the designer windows are;
Ans: Max jobs:
The max job specifies the number of processes that are available as instances in the memory. Once the limit reaches the newly created instances they will be pages out to disk. This specifies the default and non-zero () representations.
The flow limit specifies the maximum number of running instances that are available before the process starter is suspended. This limit can be used to control the number of instances that are running simultaneously and also enables protocols to generate different events.
Activation limits specify the flag that is loaded instantly in the memory. By default, it is enabled.
Ans: The benefits of grouping activities are;
|The queue is used for point to point communication||Topics are used for public subscribe|
|Messages will be delivered when the receivers and readers are not active||Messages will be delivered when the consumers are not active|
|More reliable and secured||Less reliable and less secured|
Ans: HAWK helps to monitor the tool so that you can keep your eye on the performance and health of applications. HAWK consists of three components such as Hawk Micro Agent, and Hawk Display.
The render data renders the data from the output and provides the string on the base of defined data formats.
The parse data parses the data from text content on the base of defined text formats.
Ans: The following are the two processes available to all the input activities;
Ans: There are three different modes of Tibco installation such as;
Ans: The three scenarios of Tibco engine are as follows;
Ans: When you need to handle the inside errors is known as subprocess or group and you again re-throw the errors to the caller.
Ans: The following are the important resources that are included in the EAR file such as;
Ans: Tibco service can be invoked in many ways;
Ans: One important thing is that not all the workflow will have participated in the transaction. But the following activities can participate in the transaction such as;
· Tibco I process business or works connector activities
Ans: There are four types of adapter services available such as;
Ans: The scope of the user-defined process is available when you want to define the functionalities or not even inside a process that is invoked from the process.

Ans: There are two options available for configuring the storage for process engines checkpoint repository such as;
Ans: The three output formats for XSLT;
Ans: The Tibco Runtime agent setups the Tibco environment. This Tibco runtime environment integrates the Tibco designer, JRE, JVM, HAWK, and Tibco RV.
Ans: The errors can be defined in three way mechanisms;
Ans: The Tibco transactions are used to generate the messages which are related to the business. The transactions available are JNDI and XA.
In this article, I have tried my best to explain the very important Tibco interview questions. Most of the top companies are developing their software products on the basis of Tibco software because of its unique features. This software tool is used to integrate, monitor, and analyze the data. I hope this article may help a few of you to explore the common Tibco interview questions which will be asked by any top tech companies.
Ans: Critical section is used to sync process instances so that only once process instance executes the grouped activities at any given time. Any concurrently running process instances that contain a corresponding critical section group wait until the process instance that is currently executing the critical section group completes. Particularly used for controlling access to shared variables. Critical section is one of the group actions. Others are iterating, repeat until true, repeat on error until true, while true, pick first and transaction. If we select critical section as the group, then we get two options. Single group and multiple groups.
If you wish to synchronize process instances for a single process definition in a single process engine (only one ear(instance) is deployed), perform the following:
Create a group around the activities you wish to synchronize.
Specify Critical Section for the Group Action field.
Specify Single Group for the Scope field.
Only one process instance at any given time will execute the activities contained in the Critical Section group.
If you wish to synchronize process instances for multiple process definitions, or if you wish to synchronize process instances across multiple process engines, perform the following:
Create a Lock shared configuration resource and specify a name for the resource.
To perform the synchronization across multiple process engines, check the Multi-Engine field of the Lock resource. When the process instances are executed by the same process engine, locking is performed in memory. When the process instances are executed across multiple engines, the process engines must be configured to use a database for storage, and a database transaction is performed to ensure that only one process instance is executing the critical section group at any given time.
Create a group around the activities you wish to synchronize.
Specify Critical Section for the Group Action Field.
Specify Multiple Groups for the Scope field.
Use the Browse button in the Lock Object field to locate the Lock shared configuration resource you created in Step 1.
Perform steps 3 to 6 for any process definitions you wish to synchronize. Make sure you specify the same Lock shared configuration object for all Critical Section groups.
Ans: The contents of the file will persist.
Ans: Iterate, repeat until true, repeat on error until true, critical section, transaction, pick first, while true.
Ans: The queue which has made connection first. First come first serve.
Ans: Message stays on the queue.
Ans: Fetches 4 messages
Ans: File palette, generall activities palette, jdbc palette, http palette, jms palette, parse palette, service palette, soap palette, wsdl palette.
Ans: There are 6 modes of acknowledgement. They are:
Auto – message is acknowledged automatically
Client – use confirm activity for acknowledgement
TIBCO EMS Explicit – use confirm activity for acknowledgement, only available for TIBCO EMS
TIBCO EMS no ack
Dups ok – message is acknowledged automatically on its receipt
Transactional – when a transaction is included in a process definition. The message is ack when the transaction commits
Ans: Prefetch is fetching the messages from the server before receiver calls. Failsafe property enables to write persistence messages to the file with synchronous i/o calls.
Ans: We write to output to the queue from which we received the request.
Ans: Soap event source is used for single operation, single end. Service palette is used for multiple operations, multiple end bindings like http, jms.
Ans: Use job shared variable in a critical section.
Ans: JMS Queue receiver with confirm activity. Sequencing key in a misc tab of the configuration could also be used.
Ans: It is used to call process instances in the order they are created.
Ans: All the processes which have this key in their sequencing key field will be executed in the order they were created.
Ans: SQL direct is used to execute command dynamically using output of other activities. This activity allows you to execute commands which other activities in the JDBC don’t allow, like DDL command create table.
Ans: You can change the value of a global variable when you deploy your project in TIBCO Administrator.
See the section on modifying runtime variables in TIBCO BusinessWorks Administration for more information on using TIBCO Administrator.
You can also specify values for global variables when starting a process engine on the command line. To do this, specify the following as a command line argument when starting the process engine:
where variablePathAndName is the name of the variable you wish to set, including the path to the variable if it is contained in a folder. Value is the value you wish to set the variable to.
For example, if you have a global variable named item1 contained in a folder named myGroup and you wish to set its value to 500, add the following argument to the command line when starting the process engine:
Ans: Integration can be at different application layers:
Ans: TRA stands for TIBCO Runtime Agent.
The TRA has two main functions:
Supplies an agent that is running in the background on each machine.
The agent is responsible for starting and stopping processes that run on a machine according to the deployment information.
The agent monitors the machine. That information is then visible via TIBCO Administrator.
Supplies the run-time environment, that is, all shared libraries including third-party libraries
Ans: The Java Transaction API (JTA) UserTransaction type allows:
ActiveEnterprise Adapter (using JMS transports)
to participate in transactions.
The options for configuring storage for process engine’s checkpoint repository are:
Peer means all of them have the same weight. In this case when one engine fails another one takes over and continues processing till it fails.
In master secondary configuration weights are unequal, the secondary starts processing when master fails. But when master recovers, secondary stops and master continues processing.
Ans: The three scenarios are:
Shared Variables across BW engines.
Locking across groups in multiple BW engines.
Wait Notify across BW engines.
Ans: We can use Repeat on Error until true
Ans: When you handle an error inside a called sub-process or group and want to re-throw the error to the caller (happens by default if you don’t handle the error in the called process)
