Introduction

This post focuses on the creation, configuration and tuning of an initial WebLogic Server 12.2.1.1.0 Domain.

The WebLogic Server is a necessary requirement, and must already be installed. For instruction how to install the WebLogic Server 12.2.1.1 please refer to my previous post: WebLogic Server 12.2.1.1.0: Installation on the Linux OS

The following tasks will be implemented:

· Preparing the Operating System for the installation of the WebLogic Server 12.2.1.1, Installation JDK 1.8 and the WebLogic Server 12.2.1.1: please refer to WebLogic Server 12.2.1.1.0: Installation on the Linux OS

· Creating of database schemas

· Creating an initial WebLogic Domain

· Post-Installation Tasks:

· Configuring of components

· Creating of Start & Stop scripts for the automatic start/stop of components

· WebLogic Domain Tuning and Troubleshooting

The Domain will be reated on two servers (OS OEL 6.7):

· host01.example.com

· host02.example.com

We will configure two managed Server for Web Services in cluster: Read the complete article here.

Valuable Features:

It’s a very scalable, extensible, middleware component. It’s especially useful for big data applications if you’re using APIs or have geo-spatial data or complex data sets.

It’s also a very affordable and efficient.

Room for Improvement:

I would like to see Oracle offer the WebLogic Suite in other areas, like SaaS or PaaS. From what I’ve seen at Oracle World, they’re already moving in that direction, so it gives you a broader portfolio or different ways to leverage their technology.

Deployment Issues:

We haven’t had any issues with deployment.

Stability Issues:

It’s very stable. It can handle a lot of database storage and repositories. It’s really the backbone of a lot of our systems that we use for our federal customers. It’s very smooth and not buggy, and now that more people are learning how to troubleshoot and work with the product, it’s becoming exponentially easier to find quality to support it during the WebLogic application process.

Some tips when debugging WLS cluster stability

In one environment we had problems with cluster stability – and there were unnecessary migrations of JMS Servers.

Here are some settings that gave more info in logs. Set the following for the JVM:

-Dweblogic.debug.DebugServerMigration=true -Dweblogic.debug.DebugSingletonServices=true 

Change the below setting to DEBUG

 Home >Summary of Servers >AdminServer >Logging >General >Advanced >Minimum severity to log: 

enable below debugs from the weblogic admin console.

 Debug >weblogic >core 

cluster Collapse Node

 
 DebugAsyncQueue 
 DebugCluster 
 DebugClusterAnnouncements 
 DebugClusterFragments 
 DebugClusterHeartbeats 
 DebugLeaderElection 
 DebugReplication 
 DebugReplicationDetails 

Change the logging severity to Debug

 Servers-->Server_name-->Logging-->Advanced--> Standard out :Severity level:Debug 
 Log file :Severity level:Debug 

Restart.

Also look at Cluster » Monitoring » Summary to see the number of sent / received / retransmitted. For a healthy system sent and received should be almost same – and retransmissions low. Read the complete article here.

imageWebLogic 12.2.1 includes support for Zero Downtime Patching, providing the ability to roll out out a newly patched Oracle Home across a domain or cluster without downtime — all initiated via WLST or the WebLogic Console. In this session we will explore the various types of roll-outs Weblogic supports including Oracle Homes, JDKs, applications as well as the ability to simply perform a rolling restart across a domain or cluster. The session will also cover how failures during the rollout are automatically handled and how session incompatibility does not prevent a zero downtime roll out of a new application version. Watch the video here.
