Oracle Enterprise Manager Software Planned Maintenance

 
   
  

A critical component of managing an application includes both patching and maintaining the software. Applying patches is not only required for bug fixes, it is also a means of obtaining new and beneficial functionality. Thus it becomes an important  task to maintain a healthy and productive Enterprise Manager (EM) solution. The process of patching itself can present different challenges that can potentially increase the work and time involved in each patching exercise. Issues could arise such as patch conflicts, not meeting required  prerequisites and even unnecessary downtime. Spending the proper time to setup a patching strategy can save time and effort as well as possible errors and risk when patching a production EM environment.

The MAA team has recently published a new whitepaper which provides an overview of the recommended patching strategy for Oracle Enterprise Manager.  This information is intended to be a guideline for maintaining a patched and highly available EM environment and may need customization to accommodate requirements of an individual organization.

There are five main topics covered in this paper as outlined below:

  1. Enterprise Manager Components

  2. Defining Business Requirements

  3. Patching Strategy Overview

    1. Types of Patches

    2. Define Patch List and Steps

    3. Planning

    4. Preparation

    5. Testing

  4. Sample Patching Steps

  5. Optional Patching Strategy

Operational Considerations and Troubleshooting Oracle Enterprise Manager 12c

Oracle Enterprise Manager (EM) 12c has become a valuable component in monitoring and administrating an enterprise environment. The more critical the application, servers and services that are monitored and maintained via EM, the more critical the EM environment becomes. Therefore, EM must be as available as the most critical target it manages.


There are many areas that need to be discussed when talking about managing Enterprise Manager in a data center. Some of these are as follows:

• Recommendations for staffing roles and responsibilities for EM administration

• Understanding the components that make up an EM environment

• Backing up and monitoring EM itself

• Maintaining a healthy EM system

• Patching the EM components

• Troubleshooting and diagnosing guidelines

The Operational Considerations and Troubleshooting Oracle Enterprise Manager 12c whitepaper available on the  Enterprise Manager Maximum Availability Architecture (MAA) site will help define administrator requirements and responsibilities.  It provides guidance in setting up the proper monitoring and maintenance activities to keep Oracle Enterprise Manager 12c healthy and to ensure that EM stays highly available.
