Introduction This post describes how to build a vServer using LVM2. Main Article For a customer Proof of Concept - demonstrating the benefits of Oracle Fusion Middleware on Exalogic Virtual - we decided to build a custom base template. All vServers created by using this custom base template enable some customer specific configuration settings, activation of additional services and yields flexibility for the file-system layout. We decided to use Logical Volume Management LVM2...

Introduction We have already written a good article about how to configure Java Object Cache in clustered environment which you can find it HERE. There are two things on top of that, I would like to share with you regarding the Java Object Cache: which managed server needs JOC and how to verify if JOC is running. Main Article The documentation section here, says that the JOC should be configured on all servers running Oracle Web Service Manager (OWSM) and Oracle WebCenter...

Introduction Inter Portlet Communication (IPC) is designed to allow portlets to communicate with each other. The JSR 286 standard describes how portlets should be build, so they can expose events and parameters that can be read by another JSR 286 portlet. The assumption of this is that both portlets are on the same page. The standard however, does not describe how portlets can communicate with each other when they are placed on different pages. The concepts of a portlet is...

Introduction If you have a number of WebLogic Server instances running, or applications that write a lot of information into the logs, you might find that your log files, and your stdout files start to eat up a lot of space very quickly. Main article This can be easily managed with log rolling utilities like logrotate for Linux or logadm for Solaris. These allow you to automate the process of removing old log entries, and they work by moving the log file contents out through...

Introduction This post explains why probe-based failure detection is required if there is VNIC created over eoib0 and eoib1 on a compute node running Solaris. Main Article There are lots of reason for customer to create VNIC over eoib0 and eoib1 on a compute node running Solaris, two typical examples are compute node needs to connect to a VLAN over the EoIB network there are containers running on the compute node that require 10GbE connectivity We talked about why Transitive...

Introduction This blog describes a script that simplifies certain tasks in the Exalogic iaas cli. Main Article Having worked with the Exalogic Command Line for a while I decided to wrap some of the common functions in a simplified bash script. This saves me creating the keys, connecting and identifying the appropriate Ids. Instead I can simply specify the Name and the script will do the rest of the work. This initial version has just a few commands in it but as I add more the...

Introduction This blog describes the process of cloning an existing vServer. Main Article Following on from my Blog entry "Scripted Template Generation from an existing vServer" I have built a wrapper script that can be used to execute the Template Generation script or Clone a specific vServer. This script was not incorporated into the original script because it must be executed on a Compute Node with access to the /OVS/Repositories directory and the Compute Node are a...
