07 Aug 2013 Operational Considerations and Troubleshooting Oracle Enterprise Manager 12c [32187]
An Oracle White Paper

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.

05 Aug 2013 Linux Container (LXC) -- Part 2: Working With Containers [32185]
How to work with containers with practical examples

Lenz Grimmer writes, "Part 1 of this article series provided an overview about the Linux container technology. This second part intends to give you an impression on how to work with containers, by showing a few practical examples. These can be easily followed and reproduced on an up to date Oracle Linux 6 system. For the first steps, it is recommended to install Oracl Linux inside a virtual environment like Oracle VM VirtualBox. Oracle provides a pre-installed and pre-configured Oracle Linux 6 Virtualbox image for free download from the Oracle Technology Network (OTN).

The administration of Linux containers is performed on the command line; so far, there is no integration or support for this technology in applications like Oracle VM Manager or Oracle Enterprise Manager..."

"The objective of this whitepaper is to help operational teams, administrators and IT managers comprehend some of the more advanced features of Oracle Enterprise Manager 12c, so you can take full advantage of all the features and capabilities within the software, in order to get the most out of your Oracle investment-rather than just use Oracle Enterprise Manager 12c for basic capabilities, such as monitoring, metrics, thresholds, alerting and so on. While such capabilities are very useful, we need to go beyond monitoring into deep-down management of your applications, databases, middleware and server hosts.

This whitepaper gives you in a nutshell, a number of advanced techniques for setting up and working with Oracle Enterprise Manager 12c. We look at practical use cases from the experience of industry-leading Oracle experts. Tips and recommendations range from architecture for Oracle Enterprise Manager 12c, to setting up Oracle Recovery Manager (RMAN) backups, to creating and managing Oracle Active Data Guard standbys through Oracle Enterprise Manager 12c as well as other advanced capabilities..."

01 Aug 2013 READ_ME_FIRST: What Do I Do with All of Those SPARC Threads? [32054]
What to do with the 1,536 threads in an Oracle M5-32 system

"With an amazing 1,536 threads in an Oracle M5-32 system, the number of threads in a single system has never been so high. This offers a tremendous processing capacity, but one may wonder how to make optimal use of all these resources.

In this technical white paper, we explain how the heavily threaded Oracle T5 and M5 servers can be deployed to efficiently consolidate and manage workloads using virtualization through Oracle Solaris Zones, Oracle VM Server for SPARC, and Oracle Enterprise Manager Ops Center, as well as how to improve the performance of a single application through multi-threading..."
