Performance Test on TIBCO BusinessWorks Subprocess Calls
One of our clients had asked us about the difference in performance between a TIBCO ActiveMatrix BusinessWorks process that uses a subprocess call and one that does not. In other words, one TIBCO process called a subprocess to perform a certain functionality, whereas the other process had the functionality embedded in itself. The functionality in question was a simple JMS Queue Sender activity that sends a JMS queue message to the JMS server. The client was concerned that there may be a large enough performance difference between these two processes to discourage the use of subprocess calls on any process where performance is critical.
The TIBCO Certified Professionals in our company set out to find out the difference in performance between these two processes. We endeavored to answer the following question: how much of a performance cost does a subprocess call incur in TIBCO ActiveMatrix BusinessWorks?
We set up one process that had the functionality embedded in it:
We setup another process with the same exact functionality being called as a subprocess:
We then called these processes individually 10,000 times each using the following loop from a caller process:
The time it took to for each process to execute 10,000 times was noted. The test was repeated 10 times for each process.
Here are the results:
| Test | No Subprocess Call | With Subprocess Call |
| 1 | 1484 | 1781 |
| 2 | 1563 | 1766 |
| 3 | 1453 | 1782 |
| 4 | 1469 | 1797 |
| 5 | 1422 | 1766 |
| 6 | 1469 | 1782 |
| 7 | 1437 | 1781 |
| 8 | 1485 | 1782 |
| 9 | 1437 | 1766 |
| 10 | 1516 | 1797 |
| Average: | 1473.5 | 1780.0 |
To execute 10,000 times, the process that had the functionality embedded in it took 1473.5 milliseconds. On the other hand, to execute 10,000 times, the process that called the functionality as a subprocess took 1780.0 milliseconds. The difference is 306.5 milliseconds. This may seem like a large difference at first, but remember that this is for 10,000 executions. For just one execution, the difference is only 0.03065 milliseconds (306.5 / 10000).
So, surely, executing an embedded functionality is always going to be faster because there is no need to call another process to perform the functionality. Notice, however, that the difference is extremely small. The question a TIBCO architect must ask is, “Is the difference of less than 1 millisecond per execution large enough to warrant giving up the advantages of subprocesses?” One must look at the performance requirements and Service-Level Agreements (SLA) in order to properly answer this question.
The processes were deployed into a desktop computer with an Intel dual core 3 GHz CPU and 2 GB of RAM.

TIBCO tibbr Takes Workplace Communications to a New Level
Social networks and microblogging sites enable information exchange among various people. We have been using these tools for quite a while now and we receive short updates coming from people (or friends) all the time. But, what if we are not interested with what a particular person is eating for today but we want to know more, for example, about the latest report on Haiti? Twitter makes it possible to filter phrases or topics from tweets but you may not end up finding the right information you want from among the hundreds of results.
It’s amazing how TIBCO, a company that offers business integration solution to disparate systems, pioneered the twisted ‘Twitter’ for the wokplace that “allows information to easily find you,” instead of the other way around, with the release of its new product tibbr. Powered by TIBCO Silver, the first software platform for cloud computing, tibbr permits you to follow subjects and not just people. A subject can be a grain of significant information which may be more relevant in a business scenario than the person where the information came from. If you want to know about the performance of your sales or the status of your marketing, you can follow those subjects and the relevant information you need and want will come knocking at your door. In addition to following subjects, tibbr also permits following machines which means you can subscribe to important messages from different automation systems. While Twitter is built on a public network, tibbr maintains a scalable, secured, highly available and reliable delivery of information which is private and more suitable for the enterprise.
Twitter and tibbr both have one thing in common, that is, both of them are real-time communication tools. One notable thing about tibbr, however, is that it has the functionality that gives the users the ability to discard duplicate posts or re-posts (called retweets in Twitter lingo), and eliminate lengthy “reply all” email strings. By centering on the subjects, tibbr eliminates what TIBCO calls as “static and unwanted information clutter.” Unlike social networks, tibbr is geared towards the delivery of needed and wanted information relevant to an employee working on a specific part of the enterprise context at a precise time. Subjects can include not just topics but users and business processes as well.
It is therefore time that this software technology in its newest shape become a part of the enterprise. TIBCO has again taken the lead in the attempt to make communications better within the workplace.

TIBCO ActiveMatrix BusinessWorks – Excellent Graphical Modeling of Business Processes
Automation of business processes is crucial, and doing it manually prophesies a higher probability of detrimental risks. In the business context, they can be bombs against profitability such as time delays, improper implementations, deployment problems, or buggy application. TIBCO provides a way out with its ActiveMatrix BusinessWorks product which allows modeling of business processes graphically. Such graphical rendition of a business process is called a process definition. BusinessWorks comes with a Designer tool which provides an environment for developing and testing process definitions. The execution of process definitions involves creation of their corresponding process instances which is seamlessly handled by the TIBCO ActiveMatrix BusinessWorks process engine. Each process instance is an automated business process in action.
A TIBCO process definition has five building blocks, namely: Activities, Transitions, Groups, Shared Configuration Resources, and Subprocesses. The logical combinations of these components define how a process definition intends to function.
In its simplest form, a process definition is a sequence of activities and transitions. It starts with either a Start activity or a process starter and ends with an End activity. Activities are the specific individual units of work which defines the actual operations and processing. They are logically grouped with their related counterparts into sets known as palettes. For example, all operations pertaining to file processing, such as reading, writing, or copying a file, are represented with their corresponding activities: Read File, Write File, and Copy File. These activities are grouped in the File palette. Similarly, all tasks that pertain to database access and manipulation are grouped in a single palette – the JDBC palette. On the other hand, transitions define the control flow as to when activities in the process definition take their turn. It is graphically represented by a unidirectional arrow between activities. It directs how interaction between activities should proceed, dictating how and when activities get executed. Although an activity may exists in a process, when there are no transitions that connect it to the entire flow with other activities therein, it can never be executed.
There are situations when an activity or a certain collection of activities in a process definition must be treated as a single task, be bound to a particular repetition, or be constrained by certain conditions. This is where Groups come in to support extended capabilities for the process to handle loops, transactions, collective error trapping, or synchronization. TIBCO provides nine group actions; each is unique for a particular purpose. These are as follows: No Action, If, Critical Section, Pick First, Iterate, Repeat Until True, While True, Repeat On Error Until True, and Transaction.
Each activity contains specifications that must be configured in order to meet the required behavior from it. A configuration can be properties, pieces of input and output information, or error schemas that must be supplied with proper settings or entries. However, there are specifications that are shared among activities like database connections, WSDL files, schema definitions, etc. With this, it is necessary to use Shared Configuration resources. They actually do not form part of the explicit flow but are created outside process definitions and are used in the Configuration tab of activities. Activities make references to these shared resources in order to make use of them.
What about a subprocess? A subprocess is a process definition called within another process definition. This is ideal when modeling a very complex business process. Plotting the entire logic flow in one gigantic process definition complicates how the business process is represented. Turn it into bite-size bits by chopping one complex process into smaller processes definitions and then call the latter from the main process. Subprocesses make process diagrams more readable and easy to comprehend, trace, and countercheck. Another good thing is that subprocesses are reusable across different process definitions. Just a note, they cannot contain process starters.
In short, TIBCO ActiveMatrix BusinessWorks provides the convenience and efficiency of graphically modeling business processes and executing them automatically. It saves you the pain and agony of weaving complex business processes manually like you have to do in other programming languages. Our TIBCO consultants use this graphical style of development to productively create business applications for our clients.
