clip_image002Introduction

Using the multi-tenancy features of WebLogic Server 12.2.1, administrators can use domain partitions to share computing resources in the WebLogic domain across different tenants. Administrators can also simplify administration and management by consolidating multiple WebLogic domains into multiple domain partitions in a single domain.

Yet sharing the same resources across multiple partitions works against isolating the partitions from each other for security and privacy reasons. This short article explores that tension and highlights how you can use the multi-tenancy features to optimize sharing or isolation.

Virtual Targets

To see how all this works we need to talk about virtual targets in WebLogic Server and their role in multi-tenancy. Briefly, a virtual target does two things:

  1. It establishes how end users connect to apps in a partition (using a partition-specific URI prefix, a partition-specific port number, etc.)
  2. It refers to a WebLogic cluster (or individual server).

The WebLogic administrator creates one or more virtual targets, associating each with a server or cluster, and creates one or more partitions, linking each partition with one or more virtual targets. These associations control where the apps and resources in each partition will run.

Sharing Resources

Here is how you would set up a domain’s virtual targets and partitions to maximize resource sharing.

This is the typical consolidation use case – often called the PaaS (platform-as-a-service) model. Several divisions of one enterprise – for example, HR and Finance for one company – might have their own separate partitions in a single WebLogic domain but want to share the computing resources.

In the simplest example, the WLS administrator creates a virtual target for each partition and links each virtual target with the same cluster (including managed servers MS1 and MS2). Applications and resources from different partitions run in the same managed servers. In this way the WebLogic administrator can share the hardware and software resources on those servers – including the Java virtual machine – across the partitions.

This lets the administrator achieve higher density. Because the partitions are part of the same enterprise, isolating the partitions’ code and data from each other might not be a major concern.

In contrast, if a single WebLogic domain is hosting different enterprises, each as a different partition, questions of isolation become much more important.

Even so, sometimes it might still make sense for different partitions to share the same managed servers. For example if you are offering access to a suite of applications to different customers you have full control over those applications. If you are confident in the applications themselves you might be willing to have different partitions share the same managed servers, comfortable that the apps themselves are well-behaved and will isolate data for one partition from data for another.

clip_image002WLDF is a diagnostic framework inside Weblogic, which provides several functionalities to measure, track and monitor a domain at runtime. With WLDF, administrators can set alarms on specific incidents and automatically execute some tasks when certain events are triggered.

One good starting point to learn about WLDF is Radu Dobrinescu’s blog. It provides a compressive tutorial on how to monitor common events in Weblogic. The newest version of Weblogic (12.2.1) has made some changes and improvements to the WLDF Framework with the inclusion of the new smart rules.

Smart rules provide a set of predefined rules that represent the most common monitored events in Weblogic domains. This blog is going to show how to monitor stuck threads and overloaded datasources and send an email if one of these events occurs.

1. Creating a mail session

The first task required is to create a mail session in order to reference it in the WLDF watches. The following steps explain how to define a mail session.

  • In the domain structure go to Services -> Mail Sessions -> New
  • Enter a name, a JNDI name and your user account in Weblogic. In the JavaMail properties enter at least the host and port of the SMTP server and the sending email account, like this:

mail.smtp.port=2525

mail.smtp.from=“soa_admin@example.com“

mail.smtp.host=localhost

  • Press “Next”.
  • Select the server where you want to target this mail session and press “Finish”.

2. Create a Diagnostic Module

A diagnostic module is and administrative unit that contains collected metrics, instrumentations, policies and actions. The following steps show how to define a diagnostic module. Read the complete article here.

clip_image002 The release of WebLogic 12.2.1 has introduced some cool features. One of them: the domain partition exports. Could this feature really reduce all the deployments to just one deployment? Let’s find out!

To fully grasp the idea of just needing one deployment, we need to explain Domain Partitions first. As Oracle states: “A domain partition (partition for short) is an administrative and runtime slice of a WebLogic domain. In many ways you can think of a partition as a WebLogic micro-container.” A Domain Partition can be assigned as micro-containers called Resource Groups. Resource Groups can contain WebLogic components such as applications, libraries, JMS Servers and Data Sources.

Resource Groups and Templates

In previous WebLogic versions you would deploy WebLogic components to the whole domain (global) and have it targeted to servers or clusters. Starting from 12.2.1, you can now also deploy these WebLogic components to specific Resource Groups and Resource Groups Templates. Resource Groups can be used to group every component needed in a business flow to one container.

Using Virtual Targets, Administrators can specify on which servers or clusters the Domain Partition is available. Read the complete article here.
