WebLogic Admin Tricks & Tips

My learning Kubernetes Cluster is an essential skill for SRE DevOps Engineers on any Cloud platforms. My learning capability keep growing with this daily dose !! :) I like the statement given in one of the author -Kubernetes is like captain of ship where multiple container clusters carried in the huge ship. This is a first step that will help you to enter into world of Kubernetes cluster technologies. Kubernetes is also known as k8s, this is quite young technology in the DevOps stack. Here we have two options to work-out on Learning Kubernetes: Kubernetes installing in master-slave in multiple nodes Minikube running a locally single node The first option will be used in real-time production environments, and the other is used for learning purposes. Here I've selected the second option for running WebLogic on Minikube. Benefits of Kubernetes cluster There are many benefits but in brief for WebLogic   Kubernetes is the core component in Cloud Native Engineering pla...

In the earlier post you have seen how to use docker-compose for WebLogic images to build and also run the container with new application deployment. In this post you will be able to see the WebLogic managed servers forms cluster and the application will be deployed on top of it. Prerequisites Let me keep the list of prerequisite steps which you can follow my previous blog post or youtube video.  docker pull oraclelinux:7-slim   git clone https://github.com/oracle/docker-images.git  download server-jre1.8 latest version copy to OracleJava/dockerfiles build the image and make it as oracle/serverjre:8 download weblogic 12.2.1.2.0 quick installer which is used for development, it is small in size. image name it as oracle/weblogic:12.2.1.2-developer   create new docker images where 12212-domain:latest using WLST and shell script which are available in container scripts.  create new docker images named as 1221-appdeploy:latest where it uses 12212-doma...

Learning docker-compose for WebLogic with examples The docker-compose is one of the docker integration tool. it works based on yml or yaml file. The yml files are easy to read plain like English text. It is developed alternative to JSON files, both are used to store the key, value pairs and hierarchical structured data. To run docker-compose command in the current directory there should be  docker-compose.yml file must be exist. Prerequisites for docker-compose well awareness of docker YML syntax docker network docker-compose build with Example Dockerfile is used to build the docker image that should be present in the current directory. Create docker-compose.yml file Lets create the docker-compose.yml file for WebLogic Domain container which uses 1221-appdeploy image. The AdminServer port exposed as 7001 from the container and on left side host port opened with 7001. The container should run the command/shell script. here we can select startWebLogic.sh as start...

Writing this blog post after couple of executions experiments and research on docker. The basic requirement for docker is there must be a Linux/Unix based platform. Here I am creating that one on my Windows host machine, and the guest Ubuntu Trusty64 platform with the help of Vagrant and Oracle Virtualbox provider. vagrant Ubuntu docker - Oracle Linux images In this Article I am not dicuss about from the scratch What is docker etc. I'm not talking about Virtualization vs Containerization. Create testnode1 folder on the Windows machine. I've created on F:\testnode1. The Vagrantfile to launch Ubuntu Trusty64 Virtual machine is as follows: Vagrantfile # -*- mode: ruby -*- # vi: set ft=ruby : Vagrant.configure(2) do |config| config.vm.define "test" do |testnode1| testnode1.vm.box = "williamyeh/ubuntu-trusty64-docker" testnode1.vm.hostname="testnode1.vybhava.com" testnode1.vm.network "private_network", ip: "192.168.33...

Configure a WebLogic Server Background Service server running in the background which is very much required in Production and Test Environments where your operating platform is Windows NT based. Whenever the Windows server is rebooted the WebLogic Admin server or Managed servers running on it are going to started automatically, when they are configured with windows ‘services’. Use WebLogic existing Domain or Create a Domain for testing  Create a installation Script per WebLogic server such as AdminServer or Managed Server Create a .cmd let us workout per AdminServer  with the following  Open notepad or any editor to write the following Windows batch Script echo off SETLOCAL set DOMAIN_NAME=demoDomain set USERDOMAIN_HOME=F:\irfan\demoDomain set SERVER_NAME=AdminServer call "F:\Oracle\wlserver\server\bin\installSvc.cmd" ENDLOCAL Write the above code and SAVE it with ‘AdminServerSrv.cmd’ in your domain\bin open a n...
