Enterprise Manger Grid Control 11g Installation on RHEL5 x86_64


On April 22, 2010 Oracle released a new version of their grid-enabled management software - Enterprise Manager Grid Control 11g. As a DBA I have come to rely heavily on this tool for the monitoring of databases, notifications and the ability to quickly diagnose and tune performance related issues (with the Diagnostics and Tuning Pack). Most of our databases are on Oracle 10gR2 but we have been planning several upgrade projects to 11gR2. Given that we are currently on Enterprise Manager 10.2.0.4 - 11gR2 databases are not supported. According to the Oracle Enterprise Manager Grid Control Certification Checker [ID 412431.1] an upgrade to release 10.2.0.5 along with required patchsets would be required in order to support 11gR2 targets, and even so some features would not be supported. I decided that instead of going to 10.2.0.5 altogether I would start testing the 11g release since it would fully support all of the databases new features. Unfortunately, since only the Linux and Solaris versions are available at the time of this writing, I could not do test the upgrade (we run EM Grid Control on AIX :( ) Anyway I went ahead with a fresh install of Enterprise Manager 11g using an existing 11gR2 database on RHEL5 x86_64.
I even did a video of the installation. I won't go into the details of the installation, suffice to say that there are tonnes of documentation on My Oracle Support site (which seems a bit overwhelming). Since 11g now uses WebLogic as the middle-tier, I was a bit apprehensive as to how the enter process would go. It wasn't difficult at all. Needless to say that be prepared to do a lot of prerequisite checks. I had to install JDK 6 before doing the WebLogic Installation. I've also compiled some notes and prerequisites to get an idea of the requirements to check for before starting the installation.
The usual disclaimer applies - DO NOT FOLLOW MY EXAMPLE TO INSTALL IN YOUR PRODUCTION ENVIRONMENT. IT'S FOR TESTING AND EDUCATIONAL PURPOSES ONLY.
Please note that my installation failed a couple of prerequisites.  My VM only had 2GB of RAM and the compat-db-4.1.25-9 package was missing.  I foolishly ignored those errors and proceeded with the installation.  The installation was successful however.

Setup a Wordpress site in 10 Minutes using Oracle Container Cloud Service

Image
Oracle Container Cloud Service Oracle Container Cloud Service lets you easily deploy applications based on docker images. If you don't have an existing application you can create one on docker. However, the easiest method to get a full application up and running is by deploying a stack. Oracle Container Cloud Service provides several example stacks that you can deploy, including web servers based on NGINX or Apache, MongoDB database, and Wordpress. You can find more examples on Oracle GitHub Site . Let's see just how easy it is to spin up a Wordpress site using the Oracle Container Cloud Service. Prerequisites: Access to Oracle Cloud Account Subscription to Oracle IaaS Service First, go to the Oracle Container Cloud Service console and launch a new service. In this example, I created a service with three containers. One manager and two worker nodes. Choose an appropriate "shape" for your compute instances. Note: Oracle uses the term "shape" to r...

Oracle Home Cloning: Tools and Techniques

One of the many necessary and frequent tasks that a database administrator performs before creating a database is installing the Oracle database binaries. These binaries form what is known as an Oracle Home (referenced by the ORACLE_HOME environment variable on Linux and UNIX environments). Unfortunately, this is also one of the most mundane and uninteresting tasks a DBA can perform. So like all good DBAs know, the best way to deal with such repetitive task is to automate it. Automating installations of Oracle database binaries enables us to reliably repeat the process to enable faster installation as well as provide identical copies of the software in multiple environments. Fortunately, Oracle allows us to clone the Oracle database binaries from one environment to another. Cloning your Oracle binaries from a source copy with all the necessary patches applied enables us to have gold images which can then be deployed to multiple environments. The procedure for cloning an Oracle home...
