At Payara Services, we have long been advocates of the benefits of using DevOps practices not only in the development of our products (like Payara Server & Payara Micro), but also in the core of our expert advice to our user base with our blog containing arguments for using DevOps practices, details of DevOps tools and new developments that benefit it.
This is an updated blog of the original which was published in May 2016
Payara Server provides the Health Check Service for automatic self-monitoring in order to detect future problems as soon as possible. When enabled, the Health Check Service periodically checks some low level metrics. Whenever it detects that a threshold is not met, it triggers alert notifications that allow to detect undesired behavior and predict possible failures. All of these automatic checks are very lightweight and run with a negligible impact on performance.
Back in 2016, we wrote about the importance of automation in taking applications from development to production with Payara Server. Since then, there have been a lot of changes both in Payara Server and Payara Micro and the wider tech landscape.
Since Java EE 6 it's possible to define data sources in a portable way.
This does mean though that the data source is embedded in the application archive. For some use cases, this is exactly what's needed, but for others it may not be ideal.
Now that the ForgeRock tools have been installed, we will configure them with some basic access configuration. First, proceed to login to the OpenAM application (context /openam) with the amadmin user, and the application will show you the current realm configuration for your domain:
Today, one of the most important concerns for enterprise applications is to implement robust security mechanisms that allow developers and operation staff to easily integrate applications in a stable infrastructure and allow their users to interact with them in a seamless way. While many developers prefer to implement their own security mechanisms or use third-party libraries, a good alternative is to use already established products that handle authentication, authorization, confidentiality, identity, and entitlement on behalf of already developed applications.
Payara Micro allows you to run web applications in a self-contained and easy way. Since the release of the Payara Server in May 2016, there is a simple way to generate an "Uber" JAR that bundles the contents of a WAR file and the classes and resources that compose Payara Micro!
Note that this "Uber" Jar is not the best way to run your application in a Docker container as it requires an update of the entire binary for each small code change you make in the application. A better solution is just to start a Payara Micro Instance and point to the application that needs to be installed. More information can be found on our Payara Micro Docker Image documentation.

The HealthCheck Service provides automatic self-monitoring in order to detect future problems as soon as possible. The HealthCheck Service was introduced in Payara Server and Payara Micro version 161 and some new metrics have been added in version 162.
All the functionality of the HealthCheck Service that is available in Payara Server is also included in Payara Micro. However, as Payara Micro differs in some concepts from Payara Server, the usage and configuration of the HealthCheck Service is slightly different. In this post, we will focus on how to use it in Payara Micro.
