This was my first time attending Oracle Code One, and by extension traveling to San Francisco.

As part of the Payara Enterprise Support services that we deliver to customers on a daily basis, giving expert advice and clarifying how the internals of the products of the Payara Platform work is one of the most common scenarios we encounter. Here's' a story about the advice we gave to one of our customers regarding the behavior of JDBC Connection Pools in Payara Server.

Last week, the Colombian chapter of the Latin American JConf Conferences was held in the beautiful city of Medellin, Antioquia. There were multiple Java related talks across the 5th and 6th of July in two tracks:

One of the biggest challenges when developing applications for the web is to understand how they need to be fine-tuned when releasing them into a production environment. This is no exception for Java Enterprise applications deployed on a Payara Server installation. 

Running a Payara Server setup is simple: download the current distribution suited for your needs (full, web); head to the /bin folder and start the default domain (domain1)! However, keep in mind that this default domain is tailored for development purposes (a trait inherited from GlassFish Server Open Source). When developing a web application, it’s better to quickly code features, deploy them quickly, test it, un-deploy (or redeploy) it and continue with the next set of features until a stable state is reached. 

Nowadays, the concept of microservices is more than a simple novelty. With the advent of DevOps and the boom of container technologies and deployment automation tools, microservices are changing the way developers structure their applications. With this article, our intention is to illustrate that microservices are a valid option for Java/Jakarta EE developers and how Payara Micro is a robust platform to reach that goal. 

Starting this year, customers that come on board with our support services also have access to commercial OpenJDK support included, thanks to the partnership between Payara Services and Azul Systems' Enterprise Support! If you are interested in Payara Enterprise or our Migration & Project Support but are hesitating and have some doubts about what value this service brings to your organization and environment, this article may help dispel them and give you much needed decision-making clarity.

今日、マイクロサービスのコンセプトは単に新しいだけではなくなっています。DevOpsの登場、コンテナ技術ブーム、デプロイ自動化ツールによって、マイクロサービスは開発者が手掛けるアプリケーションの構造を変えつつあります。マイクロサービスはJava EE開発者にとっていかにして有効な選択肢となり得るのか、そしてPayara Microとそれが提供する完璧なプラットフォームによってどのようなメリットが得られるのかについてみてゆきましょう。

Webアプリケーションを開発する際における最大の挑戦の一つは、商用環境へのリリース時にアプリケーションをどのように調整すべきかを理解することです。これはJavaのエンタープライズ・アプリケーションをPayara Serverへデプロイする場合でも例外ではありません。

As part of release 4.1.2.173, new notifier integrations were developed for Payara Server for the New Relic and DataDog application performance monitoring (APM) services. Both services allow the gathering of JVM statistics, HTTP metrics and support the use of notification for critical events in the server lifecycle management. In this era of cloud services, performance monitoring is an integral part of the IT infrastructure for any organization, which is the reason integration with these services has been brought to Payara Server. This article will show how to correctly set up these notifiers to that purpose.

A crucial component in many web applications is the use of a database. The chances of using JDBC directly or indirectly to access a relational database (through JPA or other ORM frameworks) on these applications are quite high. A common problem when dealing with relational databases is dealing with SQL queries or statements that take too much time to resolve, thus causing your application to be considered slow in producing results to the user. It's usually better to detect these issues preemptively, before sub-par performance damages your application, and Payara Server has you covered!
