Resource Consumption Management with WebLogic Multitenant by OTN

clip_image002What is WebLogic Server Multitenant?

Multi-tenancy (MT) in WebLogic Server (WLS) provides a sharable infrastructure for use by multiple organizations. These organizations are a conceptual grouping of your own choosing, which you can think of as tenants. By allowing one domain to support multiple tenants, WebLogic-MT improves density and achieves a more efficient use of resources.

WebLogic-MT provides resource isolation within a domain partition, an administrative and runtime slice of a WebLogic domain that is dedicated to running application instances and related resources for a tenant. Domain partitions achieve greater density by allowing application instances and related resources to share the domain, WebLogic itself, the Java virtual machine (JVM), and the operating system, while isolating tenant-specific application data, configuration, and runtime traffic. Read more about WebLogic-MT here.

What is Resource Consumption Management?

A premium feature in WebLogic-MT 12.2.1, Resource Consumption Management (RCM) provides resource isolation and tries to ensure that resources are allocated fairly to the partitions. It provides a policy infrastructure to limit usage of the shared resources and take appropriate actions when those specified limits are breached. It can also help maximize resource utilization in consolidated deployments.

Why is RCM important?

As we saw, in WebLogic-MT there can be one or more co-located partitions in a single JVM. When partitions are co-located, they may consume or compete for the low-level resources offered by the OS/JVM. Low-level resources are often limited in nature. The (over-) consumption of these resources by one partition may (adversely) impact the other co-located partitions. Therefore, in WLS-MT, where partitions are co-located, it is important to isolate these partitions and the resources consumed by these partitions.

For example: If there are 100 file-descriptors available on a particular OS running WebLogic-MT that has 2 co-located partitions, one partition may end up consuming most of the available file-descriptors, leaving absolutely nothing for the other partition (implying the affected partition cannot function as expected). The affected partition has to bear the cost of being co-located with

As we can see, the Blue tenant is affected adversely because the Red tenant consumed most of the shared resources. The solution is to enforce policies through the RCM, so that one partition does not end up consuming all the low-level resources. With RCM, the system admin can define policies so the consumption of resources by one partition does not adversely affect the other co-located partitions. Read the complete article here.

Podcast Show Notes: Cloud Architect: Rising to the Role by Bob Rhubart

clip_image002Each year at Oracle OpenWorld I manage to talk a group of already-busy architects into crowding into my tiny hotel room for a round table discussion on some interesting, timely topic. OpenWorld 2015 was no exception.

The catalyst for this year's conversation was Cloud Transformation Strategy: Part IV: Role of Cloud Architects, a short article on LinkedIn written by Oracle ACE Director Ron Batra, a man with considerable experience as a cloud architect. I spoke to Ron about putting a podcast together, and then put out the usual call for additional panelists.I could not have been happier with the response, and with the ensuing conversation. Though in retrospect a bigger hotel room might have been a good idea. Listen to the podcast here.

2 Min Tech Tips at Oracle OpenWorld: Are You Ready for Your Close-Up?

clip_image002At last year's Oracle OpenWorld I had more fun than should be allowed by law recording 2 Minute Tech Tip videos with about two dozen community members -- about twice the number I had originally scheduled. People just kept showing up! And that number doesn't include the Tech Tip videos I recorded in the weeks leading up to OOW14, featuring people who were speaking at the event and wanted to help promote their sessions by distilling their presentations into key take-aways.

This year I'll be at it again -- with better gear and a sleeker format for the finished videos. So if you'll be at OOW15 and have 120 seconds worth of insight an expertise you'd like to share with the world, I want you on my schedule.

I also want to hear from any OOW15 session presenters who want to promote their sessions in advance with a 2 Minute Tech Tip. Leave a comment below or contact me via Twitter @OTNArchBeat so we can work out the details.

Summer Reading for Techies By OTN ArchBeat

Looking for some summer reading? Sure, you could get engrossed in the latest bestseller, but how will that help you when your day at the beach, or on the patio, or just laying in an undersized plastic pool in your driveway is over? Just because you've slathered yourself with sunscreen is no reason not to beef up your technical knowledge while you're trying to keep cool.

With that in mind, here are three absolutely free excerpts from recent technical books.
Creating Domains with WLST by Martin Heinzl In this sample chapter from Advanced WebLogic Server Automation: Administration and Monitoring with WLST and JMX (Rampant TechPress), author Martin Heinzl starts with the minimal domain, extends it with components, and then shows "a comprehensive but flexible example of how to create a domain with a number of important features."
Watch an interview with the author.
Installing Oracle WebLogic Server 12c and Using the Management Tools by Sam R. Alapati.
This excerpt is the complete first chapter from the Oracle WebLogic Server 12c Administration Handbook (Oracle Press). In it author Sam R. Alapti introduces the three major administrative tools for managing Oracle WebLogic Server 12c: the Administration Console, the Node Manager utility, and the WebLogic Scripting Tool (WLST), and then shows you how to use them.
