MIPSAt the Imagination Summit in Santa Clara, California, Oracle and Imagination Technologies announced a collaboration around Java and the Internet of Things (IoT). Imagination is an semiconductor R&D and IP licensing company, and the owner of the PowerVR GPU and MIPS micro-architectures. This collaboration between Oracle and Imagination Technologies includes:

  • Porting and optimizing Java for MIPS for embedded and server-side applications. The current plan is to provide three different configurations:
    • The initial port will be Java SE Embedded 8 for 32-bit MIPS R2 embedded SoCs. This is still in planning but is expected some time in the first half of CY2015 (subject to change etc). This will be preceded by an extended early access program.
    • Java SE Embedded 8 will later add support for 32-bit MIPS R6.
    • Finally, we are also planning for a 64-bit MIPS R6 port. This will more likely be a general-purpose Oracle JDK 8 port aimed at servers and network equipment.
  • JavaFX support for the PowerVR GPU family. The initial target for this work will be headful embedded SoCs.
  • Collaboration around Java standards for the Internet of Things. Imagination Technologies will join the Java community and work with Oracle and other community members in this area.

MIPS has historically been somewhat fragmented in terms of multiple partially incompatible implementations, and lack of a unified source for development tools and OS support. Imagination is taking steps to address this issue with its SoC partners through the recently announced prpl open source foundation, which will work to unify and stabilize support for Linux, virtualization, open source tools and related things. Oracle is strongly supportive of this initiative. Read the complete article here.

Coherence*Web is a great feature which allows you to store your HTTP sessions in a Coherence Cluster. Doing this allows your to de-couple the HTTP sessions from your JVM’s that are running your web apps, (which can free up JVM memory) and take advantage of the RASP (Reliability, Availability, Scalability and Performance) capabilities of Coherence for storage.

With this separation you can also more easily scale and manage and your HTTP session tier as well as utilise the wide array of session management options that Coherence*Web provides.

What I’d like to show you here is how to configure Coherence*Web in WebLogic Server 12.1.2 and deploy a basic web application that utilises this.

For more detailed information on Coherence*Web and the options available, see http://docs.oracle.com/middleware/1212/coherence/COHCW/start.htm#sthref11.
Setup

For this example, I’m assuming you already have installed WebLogic Server 12.1.2 and created a domain with node manager running.
If you are not familiar with how to do this, then you can use one of my posts here as a starting point or see the product documentation here.

We are going to create two WebLogic Server Clusters and a Coherence cluster into which we shall place both WLS clusters. This will ensure that the manages servers in both WLS clusters are associated with a common set of Coherence caching services. Read the complete article here.

OHS in co-located WebLogic configurationHere’s a silly little issue I hit this afternoon – mostly a case of "administrator error" but a time waster nevertheless.
To recap, there was a big change to Web Tier administration in 12.1.2 in that OHS is controlled with what’s now called the "WebLogic Management Framework" – in short this means OHS instance configuration is handled via WLST and lifecycle (start/stop etc) by Node Manager (i.e. OPMN has gone). You have a choice of either co-locating OHS in your existing WebLogic domain (diagrams from the Oracle Documentation):
Otherwise you can have OHS on its own: Read the complete article here.

In my previous blog I described the steps to get OpenStack on Solaris up and running. Now we’ll explore how WebLogic and OpenStack can work together to deliver truly elastic Middleware Platform as a Service.
Middleware / Platform as a Service goals
First, let’s define what PaaS should be : PaaS offerings facilitate the deployment of applications without the complexity of managing the underlying hardware and software and provisioning hosting capabilities.
To break it down:
- PaaS provides a complete platform for hosting solutions (Java EE, SOA, BPM, …)
- Infrastructure provisioning (virtual machine, OS, platform) and managing is hidden from the PaaS user [administrator or developer]
- Additionally, PaaS could / should define target SLAs, and the platform should ensure the SLAs are meet automatically.
PaaS use case
To make it more tangible, we have an IT Administrator who has the requirement to deploy a Java EE enterprise application. The application is used by external users who need to submit reports by the end of each month. As a result, the number of concurrent users will fluctuate, with expected huge spikes around the end of each month. Read the complete article here.
