MuleSoft Applications: Assuring the Delivery of Reliable Messages

Published

on

There is no tolerance for the loss of messages in some MuleSoft apps. A great example is a purchasing application for online orders. A company’s sales revenue would be impacted if even a single message was lost during a purchase transaction on the online platform. Get this interactive mulesoft training course from the well-experienced experts who would assist you in expertising concepts like mule4 basics, integration techniques in AnyPoint studio, performing the test, debug, deploy and manage the mulesoft applications, learn how to identify IT problems in the industry, etc.

However, while building a MuleSoft application, there are approaches to make certain that messages are delivered reliably. Using Mule transports that are transactional like JMS and VM is one option. Messages would be safely transmitted between an outward endpoint and an inbound endpoint, or among message processors inside a flowing mule by taking advantage of the built-in transactional functionality in JMS and VM transports.

Transactions are not supported by several means of transport, such as FTP, File, and HTTP. If a message processor throws an error while receiving messages via a listener of inbound HTTP, the application risks losing the messages.  To achieve reliable message delivery for transports that are not transactional, a dependability pattern will be utilized.

A pattern of reliability is indeed a design strategy that combines inbound non-transactional transport (HTTP) and synchronous flow known as a reliable flow of acquisition, outbound transactional transport (VM) to ensure reliable message delivery.  Receiving inbound messages, verifying them, and storing them in a queue via a JMS or VM connector is the responsibility of the reliable acquisition flow. The flow of logic in an application is where the business logic for the application is implemented.

It’s crucial to remember that the reliable flow of acquisition must use an asynchronous processing technique. This ensures the message was verified and sent in one thread to the outgoing VM destination. In addition, the logic of the application flow’s inbound VM endpoint should be set to transactional to enable rollbacks while processing messages when an exception occurs.

How To Solve: [pii_email_3a9d3c10845f8b9d77b2]

The Mule flow below shows how to integrate a reliable flow of acquisition with the logic flow of an application in Mule.

The steps in the process flow described above are as follows:

  1. In the reliable acquisition flow, a message is received synchronously by the listener of inbound HTTP.
  2. The payload has been configured, logged, also validated.
  3. When it is a valid message, it is queued and forwarded to the VM that is an outbound destination.
  4. The application logic flow’s VM that is an inbound endpoint retrieves from the queue’s message, initiates a newer transaction, and will set the payload.
  5. The message is subjected to business logic in an application, which either succeeds or fails.
  6. A rollback exception method will catch an exception and roll back the message to the original state.
  7. The logic flow of the application will retry to handle the message until the max no. of retries specified in the method of rollback exception has been reached.
  8. If the max no. of retries has been reached, the message would be forwarded to a Java Message Service queue for subsequent processing.

Source Code Example

The Mule flow source code is available below.

The following are few things to remember regarding the sample code:

  • ActiveMQ connector is defined in sample code. ActiveMQ can be downloaded from the ActiveMQ website.
  • For running sample code locally, go to this URL: “http://localhost:8081/test/reliable?input=fail”.
  • Success or failure is the only valid query parameter input value.  The rollback exceptions strategy is triggered when a failed input value is provided.

Overview of Reliability Patterns in Mule

A high-dependability application necessitates not only the reliability of the underlying ESB but also the reliability of individual connections. The built-in support for transactions in the transport ensures reliable messaging whether your application uses a transactional transport like JDBC, VM, or JMS. This implies, for instance, you may set up a transaction on a JMS incoming endpoint that ensures messages are only withdrawn from the JMS server when the transaction is committed. This ensures that even if an error occurs during message processing, the message can still be reprocessed.

In other words, these transports’ transactional functionality assures that messages are consistently transmitted from an inbound endpoint to an outbound endpoint or across processors within a flow.

Overview of Transaction Management in Mule

Mule uses the transaction concept to describe operations in an application when the outcome cannot be left undetermined. To put it another way, Mule employs a transaction for demarcating a group of actions in a flow that must fail or succeed as a single entity.

While applying a transaction to a connector, you could demarcate a transaction. A mule could start up a new transaction and handle the entire flow as a transaction if a Mule flow starts with a transactional resource (like an inbound connector). If your flow has a transactional outbound connector, Mule will handle the outgoing activities as a transaction. While using transactional incoming and outbound connections at the end, Mule performs the outgoing activity as part of the transaction initiated by the inbound connector. In addition, you should also ensure your transactions, statements with prestigious accounting software and Sage ERP system is one of the best choices that can solve those issues.

Conclusion

This article explains how to deliver a reliable flow of messages using JMS and VM transports. In this session, you have also comprehended the steps of processing the flow along with the sample code that illustrated the mechanism of implementation.

Choosing A Stump Grinder: Factors To Keep In Mind

Published

on

Eliminating a stump is a tricky procedure, and today we’ll be tackling the most important question related to that. What should I consider while searching for a stump grinder? 

If you plan on discarding lifeless or overgrown trees, the best equipment to put your money on is a predator stump grinder. Nonetheless, today we will be discussing what things professionals who take care of trees, landscaping contractors, or worrisome homeowners need to keep in mind while selecting one.

Major kinds

For people who rent their equipment for their businesses, the right kind of stump grinder is helpful to them, and they can switch it up depending on the project at hand. Two commonly used types available for businesses who rent their machinery are:

  • A Wheeled handlebar type of stump grinder
  • A Tracked walk-behind kind of stump grinder

Following are the things you have to check in stumps

  1. The age, density, and the size of the stumps you plan on grinding: 

These things are essential to contemplate. Trees have a wide range of thicknesses and dimensions, a freshly cut tree is harder to chew. Density makes it simpler to cut and crush them. The size of the tree also matters. A tinier grinder can work on an enormous stump, but it will take more time and effort for the person using it.

  1. The depth you want in your grind:

It is essential to know how deep you want to grind the stump; this will tell you what type of stump grinder you should choose.

  1. The type of tree you plan on grinding/its lineage:

The variety of the trees determines how lengthy it will be to crush them. Pines and conifers take longer rather than trees with hardwood stumps. They have more connected clean chips, which are easier to grind than their other tree types. So make sure that you know what sort of species you are planning on grinding and get the equipment according to that.

Safety precautions

Although it’s better if a professional handles these tasks nonetheless, if you’re taking up a DIY, you would need to take care of a few precautions; here’s a list of things to take care of in your next project.

  • Try to wear proper protective gear like glasses and gloves.
  • Check how close you need to stand to the stump with the type of model you have selected.
  • Make sure there are no people close by that may become a part of collateral damage.
  • Please read the instructions written before using a stump grinder.

Why SSD Disks Make Data Recovery Difficult

Published

on

New storage units as an alternative to hard drives have become widespread in recent times: these are SSDs or solid state drives.

Unlike conventional hard drives, SSDs lack moving components, such as magnetic platters, read heads, or motors. Thus, the only element that SSDs usually have in common with conventional disks is the electronic controller and also, in most cases, a connection interface such as SATA.

SSD drives are based on flash memory technology. USB memories and SD cards, storage devices that are already part of our daily lives, also work with this technology.

How are SSDs better than conventional hard drives?

It can be said that the main advantage of SSDs over conventional hard drives is their response speed.

Standard hard drives need substantial time getting up and running. When starting, the motor should start to rotate to move the plates to the optimum speed; the reading heads must leave their parking area and move until they are positioned correctly. Then, for each operation, the heads must wait for the rotation of the plates and position themselves in the relevant area.

However, on an SSD disk, by working exclusively with flash memory, reading or writing data is much faster. The time it takes for the drive to wake up and be ready to go, almost instantly, is also much shorter.

Pros and cons of SSD drives

There is no doubt that SSDs have a much better performance, and that without a doubt, in the not too distant future, they will gradually replace conventional hard drives in large part of our computer equipment.

But not everything is advantageous with this type of device, with price and capacity being its main disadvantages. An SSD is more expensive than a standard disk of the same size. In addition, the maximum capacity that we can find today in the market for SSDs is much lower than that available in conventional disks.

One must keep in mind that SSD units are known to experience defects in their firmware or their controllers; These malfunctions can render the disk unusable and cause us to lose our data.

Most SSD models are programmed to permanently erase the free space that remains unused in the file system. Unfortunately, this has profound implications for accidental deletion of files or folders or when they disappear due to a logical error. So there’s a high risk that the disk will delete any remaining deleted or lost files, causing them to be irretrievably lost.

What to do in case of data loss

If you know that your computer uses an SSD disk and you encounter a situation of file loss or accidental deletion, we recommend that you immediately shut down your computer and put your SSD in the hands of professionals to carry out data recovery.

If the machine is still on –either by working with it, or by trying to recover the data at home–, for every moment that more data passes, it will be irretrievably erased by the device itself, making it difficult to recover the data.

This particularity of SSD disks can be considered a good security measure for those who want that no one can recover their deleted or old information, but it can also represent a great problem in case of loss of information by accident.

We end by remembering, as always, that the best prevention is to have one or more backup copies, updated and verified, so as not to find ourselves in need to request a data recovery.

DATA RECOVERY SPECIALISTS
