As part of "Ansible automation for WebLogic" series - in this post we are going to install the WebLogic 12.2.1.3.0 quick installer. There is very interesting research on how and when to use ansible modules for WebLogic.

Current IT Trending towards devOps automation in every Software product development. I am also part of  this devOps culture. I had a thought that, How much I can leverage my regular task by making simple shell script for Installation task. As every Oracle WebLogic system administrator would pass through this situation but only few of them who have "AUTOMATION IN MINDS" could attempt to resolve this with a nicely blended Shell script. Here I would like to target two types of installations with two different Shell scripts: Fusion Middleware 12.2.1.2.0 WebLogic Server installation Fusion Middleware 12.2.1.2.0 Infrastructure installation Objective of this script is to get single hit would do multiple tasks such as: JAVA installation setting the JAVA_HOME in shell profile using Java run the WebLogic installer in silent mode YOu can use the same logic in WebLogic 14c the latest version as well. Assumptions: Downloaded Software will be stored in c...

"Don't open this files", "Don't enter into that folders", it will be dangerous... I know that very well what is missing in the system, where it is required a change but my hands kept criss cross!! Days passed I got opportunity to come again on long term. Now, the whole new System is going shapeup with my hands. The system is awaiting for me since long days. :) All those sparkling colorful ideas running around my mind, got chance to flow onto the system to form various automated scripts, which are having little in size with greater capabilities. Whenever there is a application version release the archive files(.jar, .war, .ear) need to copied to all over the remote machines. In olden days we were using 'sftp' command and its related 'put', 'm...
