This article describes how to configure MongoDB’s WiredTiger memory cache in Red Hat Mobile Application Platform (RHMAP) to prevent high-usage memory issues and Nagios alerts. If the WiredTiger cache consumes all the memory available for a container, memory issues and Nagios alerts will occur.
The WiredTiger storage engine is the default storage engine starting in MongoDB version 3.2. It uses MultiVersion Concurrency Control (MVCC) architecture for write operations in order to allow multiple different modifications to the same document at the same time.
WiredTiger also caches data and creates checkpoints to give you the ability to recover anytime it’s necessary. For example, if a MongoDB image deployed in a container fails, it is useful to recover the data that was not persisted. Additionally, WiredTiger can recover un-checkpointed data with its journal files. See the journal documentation and snapshots and checkpoint documentation for more information.

At Red Hat Mobile we understand the need for a flexible product that enables our customers to integrate with the tools they need to build their current and future applications. Our position as a leading contributor to the Kubernetes project ensures that the Red Hat OpenShift Container Platform offers this tremendous flexibility to customers and end users.
Red Hat Mobile also supports highly flexible integrations to a range of 3rd party services and products. In this article, we’ll demonstrate how Red Hat Mobile v4 and OpenShift v3 enable customers to rapidly deploy and secure their mobile applications by integrating with a third party product provided by Intercede. We’ll be using Intercede’s RapID product to enable two-way TLS (often referred to as Client Certificate Authentication or CCA) for our mobile application.

In this post, I will provide a walk through of how to set up Identity Brokering on an RH-SSO server.
Red Hat Single Sign-On (RH-SSO) provides Web single sign-on and identity federation based on SAML 2.0, OpenID Connect and OAuth 2.0 specifications.
For this tutorial, you will need:
- An RH-SSO Instance.
- A Web/Mobile Application with an OpenID Connect adapter.
- An OpenID Connect Provider Server (Such as Keycloak) to be used as the 3rd Party Identity Provider.

I was lucky enough to speak at JavaOne 2017 last month. It was my first time there, as both an attendee and a speaker.
I must say I was very much impressed. In particular, during the keynotes, I was happy to see how Java is moving forward, keeping up with the fast innovation pace in the cloud area.

As you may already know, the Red Hat Mobile Application Platform (RHMAP) is available as a self-administered, on-premise, installation as well as a hosted platform. This offers more opportunities for customers to benefit from increased security, flexibility and control over their platform.
Note: This installation is strictly for sandbox demonstration purposes. In the interests of simplicity, it will be running on infrastructure that will not be secure so no confidential data should be stored in this instance.
