Agent Performance

A friend writes:

"Do you have any tips for keeping the emagent from making a bad situation worse. For instance when everything is working well emagent hardly takes any CPU or memory, but once the host or db's start getting a high load emagent seems to start using more CPU than just about anything else. It's kind of counter intuitive to me, that something designed to monitor and notify you about problems actually becomes the problem when a server becomes short on resources."

My response:

One point to remember is that you should always upgrade to the latest version of the agent. For eg. If your central OMS is on EM11g, then your agents should also be EM11g agents and not EM10g agents. Upgrading to the latest version at the agent level will also fix some performance issues for the agent.

The issue you describe happens when there is a contention for resources at both sides. Make sure the agent is properly configured, it has enough free disk space to store its temporary work, etc. Remember the agent pre-requisites should always be followed - for eg, if you install the EM 10g agent on a box running Oracle 9i, you must ensure the OS is patched etc upto the level required if you were installing an Oracle 10g database on the same box. All such pre-requisites for an Oracle 10g database should be followed in such a case.

Many times the prerequisites are not followed, and the agent then struggles to perform on the older boxes since the OS is not patched to the level required, some packages are older than the requirement, swap space is lower than required, etc. Then, there are performance issues. So please check the setup first.

Oracle Enterprise Manager Grid Control: Advanced OEM Techniques for the Real World

Oracle’s Enterprise Manager Grid Control is recognized as the IT Industry’s leading Oracle database administration and management tool. It is unrivalled in its ability to monitor, manage, maintain and report on entire enterprise grids that comprise hundreds (if not thousands) of Oracle databases and servers following an approach that is consistent and repeatable.

However, Enterprise Manager Grid Control may seem daunting even to the most advanced Oracle Administrator. The problem is you know about the power of Enterprise Manager but how do you unleash that power amongst what initially appears to be a maze of GUI-based screens that feature a myriad of links to reports and management tasks that in turn lead you to even more reports and management tasks?

This book shows you how to unleash that power.

Based on the Author’s considerable and practical Oracle database and Enterprise Manager Grid Control experience you will learn through illustrated examples how to create and schedule RMAN backups, generate Data Guard Standbys, clone databases and Oracle Homes and patch databases across hundreds and thousands of databases. You will learn how you can unlock the power of the Enterprise Manager Grid Control Packs, PlugIns and Connectors to simplify your database administration across your company’s database network, as also the management and monitoring of important Service Level Agreements (SLAs), and the nuances of all important real-time change control using Enterprise Manager.

There are other books on the market that describe how to install and configure Enterprise Manager but until now they haven’t explained using a simple and illustrated approach how to get the most out of your Enterprise Manager. This book does just that.

Covers the NEW Enterprise Manager Grid Control 11g.
