This is not only nice when you want to revisit the alerting section but it is also very usefull in communication with the business and with a support desk. This way you can create a common truth surrounding a common language.

This can come in handy when you want to standardize the image format before using it further downstream in your business application(s). Before we dive into the specifics of how to configure this, let us first consider the following: * Read the help text of the component to understand which formats are supported * Ensure the input image is supplied in the correct format * Ensure you wrap the output image in something if you want to do additional transformations on the data further downstream {{warning}} This microlearning focuses on the image transformer component.

A high percentage indicates that the CPU is very busy handling the message traffic of that process, which indicates that other processes handled by that same CPU(s) might experience delays or issues.

The advice would be to analyze whether the current heap memory settings are still valid ** If you see a decrease in heap memory slightly after the spike in CPU this is an indication that the runtime was temporarily busy with garbage collection (a standard process within Java) to free up memory.

Should this connection be business-critical, you can use this failover functionality to create a passive failover situation that will take over when the active connection breaks down (regardless of the reason).

Key takeaways == * API Gateway can serve as a single entry point for all external or intern application users * API Gateway can simplify the IT landscape by offering a reusable entry point * API Gateway is a synchronous pattern by default * API Gateway leverages the standard capability of eMagiz around deployment, transformation, and business owner interaction == 5.

These test messages allow representing the specific user scenario's that the business has provided for validation.

Creating stored procedures and functions is not our core business, so we do not discuss how you could approach this.

In other words, what solution is used for the business process. Below is an example you can recognize as a screenshot of a design phase.

Before starting the Create phase, the test scenarios should be agreed upon with the business owners. This is one of the Definition of Done items from the Discovery (Capture & Design) phase we advise.

. * With API Gateway we mean: A collection of RESTful API operations that can be published to the outside world to give them access to applications that are linked to your business process. == 3. Error Handling from a Client Perspective == Each request executed by the client will return a success or a failure response.
