What is SOA ?

Service-Oriented Architecture (SOA) is an architectural style whose goal is to achieve loose coupling among diverse interacting software applications, enabling organizations to take advantage of existing investments in applications and systems.

SOA facilitates the development of modular business services that can be easily integrated and reused, thus creating a flexible and adaptable infrastructure.

Using a SOA approach, an organization can focus more resources and budget on innovation and on delivering new business services.

Systems that can successfully use SOA can minimize the disruption of planned or unplanned outages in an enterprise.

Some of the advantages of using SOA are:

  1. Reduction in development time and cost: SOA services are easily reused and can be rapidly assembled into new, composite applications.
  2. Lower maintenance cost: Reusable services reduce the number and internal complexity of enterprise services.
  3. High-quality services: Increased service reuse creates high-quality services through multiple testing cycles from different service consumers.
  4. Lower integration costs: Standardized services know how to work together, enabling disparate applications to quickly and easily connect.
  5. Reduce risk:Fewer, reusable services provide greater control over corporate and IT governance policies, and reduce the overall compliance risk to an enterprise.






How does SOA achieve loose coupling among interacting software agents?

It does so by employing two architectural constraints:

  • A small set of simple and widespread interfaces to all participating software agents. Only generic semantics are encoded at the interfaces. The interfaces are universally available for all providers and consumers. 
  • Descriptive messages constrained by an extensible schema delivered through the interfaces. No, or only minimal, system activity is prescribed by messages. A schema limits the vocabulary and structure of messages. An extensible schema allows new versions of services to be introduced without breaking existing services.
 
 
 

TIBCO ADB Adapter Error - “Failed to load shared library”

When starting an Adapter Service from the TIBCO Designer Adapter Tester, you might encounter this error: “Failed to load shared library, library name: adb55.dll”.

Fix this error with the following steps:

1. Open up C:\WINDOWS\system32.
2. Open up the TIBCO RV home directory (it might be C:\tibco\tibrv\8.1\bin).
3. Copy the libeay32.dll and the ssleay32.dll from the TIBCO RV home directory to the system32 directory.
4. Say yes if you are prompted to replace the files.

Restart your TIBCO Designer and try again.



TIBCO BusinessWorks On TIBCO Silver Fabric

BusinessWorks can run on  Private Cloud

TIBCO BusinessWorks is powerful enterprise integration technology that enables organizations to expose existing systems as services, build new services, and orchestrate and assemble services into applications – with little or no coding. Deployed by over 1,000 companies world-wide, BusinessWorks provides vital infrastructure for some of the most mission-critical service-oriented business environments in production today.

TIBCO Silver Fabric is a platform for creating a private cloud in your own data center that allows you to automate the provisioning and deployment of critical business applications, such as BusinessWorks, increasing your organization’s efficiency and reducing the risk of critical systems failures.

Cloud computing is being touted as the “next generation of computing” and is seen as vital to many in the IT industry. The many benefits of migrating to a cloud computing model include: increased efficiencies through shared resources, greater flexibility,global accessibility, and reduced expenses compared to standard physical computing. These benefits are offset by a few shortcomings,including loss of control and increased security risk, to name a few.

Manage Your Business, Not Your Environment

TIBCO believes organizations shouldn’t have to choose between efficiency and security. TIBCO Silver® Fabric llows you to setup a private cloud within your existing environment. This private cloud offers the same benefits as the public cloud without the additional risk. TIBCO’s solution comes with additional benefits not seen in public cloud offerings, such as automated dynamic scaling and run-time optimization – intelligent features that enable  TIBCO’s software to manage your environment, so you can manage your business.



EMS vs RV

  • EMS is server based while RV uses a communications daemon on every machine.
  • Depending on the requirements for speed and bandwidth, flexibility, security,reliability, availability and message passing between sub-nets one might require EMS or RV or a hybrid of both. 
  • Both TIBCO RV and TIBCO EMS provide authentication, authorization and secure communication. Tibco RV and TIBCO EMS both provide secure socket layer (SSL) support for all communication. Where Web access is used, HTTPS is supported as well.
  • In conclusion the EMS (JMS) hub-and-spoke model provides a better choice for the majority of EAI problems and RV is best left to its niches: high volume, high performance, 1-to-very many. 
  • Generally use RV for speed topic / broadcast messages and EMS / JMS the more you are worried about assuring messages get to a receiver.  
  • You can tune both products to go faster and more reliable. RV is basically broadcast via UDP, so needs RV Remote Daemons to cross subnets. You can bridge EMS to RV if you have specialised areas which you want to speed up.

Creating a TIBCO Hawk Domain

Creating a TIBCO Hawk Domain -

Create a TIBCO Hawk domain if you wish to isolate groups of TIBCO Hawk agents into independent monitoring sets.

Remember that each TIBCO Hawk agent can belong to only one TIBCO Hawk domain and cannot communicate with the TIBCO Hawk Display program on other domains.

The default is to monitor an entire network as one group. To use the default, omit the hawk_domain option.

Testing a Domain -

To test the domain option, temporarily set the TIBCO Hawk domain on a single system to a name such as test, then start (or restart ) the TIBCO Hawk Display.

If you entered a unique domain name, you only one discovered host should appear in the TIBCO Hawk Display main window.

This shows that only the local agent and the local TIBCO Hawk Display are using the test domain.

If the domain is as desired, you can now install it on the network systems where you want to assign specific computers to that domain.

All systems assigned to that TIBCO Hawk domain appear on the Display as part of that domain.

When finished with testing, change back to the default domain and restart the TIBCO Hawk Display to verify that it was correctly restored.



Enterprise Integration

Enterprise Integration reduces the cost ,improves the responsiveness and innovative.

Problems in IT today, that can be addressed by EAI are High Order processing cost,No consolidated view of the customer,High maintenance cost.

Integration Tool TIBCO will transforms the business into Event Enabled Enterprises.

Connections are established between systems without a coherent strategy

Connectivity based,Connection technology is standardized SOA Oriented connectivity

Integration Infrastructure is Intelligent infrastructure with support for process automation, transformation etc.


Catch activity vs Error path

In TIBCO, DB Adapters are C based and BusinessWorks is java based applications.

Hence we can't catch all the exceptions from Adapter in BW using Error path.

So we need to use either "catch" or "Write to Log" to know the error in BW. 


Scenario on EMS Server start up

If we have config file and duplicate queue/topic names are present in that conf file, so can we start this EMS server with that conf file ?

Yes,when starting EMS Server, if the duplicate queue/topic names are present in respecitve conf files, while starting up, EMS Server displays the duplicate names and the server will get start.

If  the duplicate entries are present in bridges.conf then what will happen while starting up the EMS server ?

duplicate entries are present in bridges.conf then it  displays the line number where it got the duplicate entry and server will not get start.


How can add a machine to DOMAIN from command line ?

Below are the steps to add a machine to domain from command line.

Step 1: Go to C:/tibco/tra/5.6/template/domainutility/cmdline

Step 2: Create a new file by copying the AddMachine.xml to another file name.
Ex: cp AddMachine.xml AddMachine_XX.xml


Step 3: Edit AddMachine_XX.xml, enter domain related specific entries.

Step 4: Go to C:/tibco/tra/5.6/bin, execute the following command.

./domainutilitycmd -cmdFile C:/tibco/tra/5.6/template/domainutility/cmdline/AddMachine_XX.xml –verbose

Step 5: Finish.

How can change the Global Variables value at runtime ?

To change the Global Variables value at runtime, add a property like below in the application .tra file and restart the application.

tibco.clientVar.SharedResource/Connections/MaxSessions=16


xpath function "tib:render-xml" vs "Render XML" activity

  • We can use tib:render-xml function instead of Render XML activity if we are not modifying XML structure.
  • We can't set encoding with the function, where as with activity we can.
  • By default, Render XML activity do the XML validation, not Schema validation.

  

BusinessWorks Process Design Methodology

Analysis

TIBCO BusinessWorks implicitly supports analysis and design by offering a set of objects representing services and activities as the basis for the project flow. The design team can use these objects during project design.

Domain Setup

A TIBCO administration domain is the set of software and hardware resources used by integration project.
Services Configuration

TIBCO BusinessWorks uses different types of services that can be accessed from within the process.

Process Design
Using the TIBCO Designer GUI, you create your business process using predefined activities and add
conditions and mapping as appropriate.
Deployment

The TIBCO administration domain supports a simple installation and deployment paradigm
Management and Monitoring

After the integration development team has configured and deployed the integration project, can use the TIBCO Administrator GUI for monitoring and management.
