Dear All,
in this post i am going to share Overview and Understand of the Oracle 13C OEM in detail, including the installation of the OEM theory.
What is OEM?
OEM is a comprehensive management solution provided by Oracle for monitoring
the Oracle software components in the data center or in the cloud.
OEM provides a centralized, dashboard based management platform for managing
the different products like Oracle Database Middleware application and the hardware.
Also, with the help of additional components like management plugins.
OEM is capable of managing other products like SQL Server, DB2 and other software
components.
what are the key features of OEM.
The most important key feature of the OEM is monitoring and diagnostic ability.
OEM provides features which the administrator can use for, monitor and manage
the databases and other components like operating system host, etc.
After installing the OEM component like OEM agent,
the agent will be able to monitor the different targets like database,
collect the performance details, and then provide this information with the
help of the OEM console, which is nothing but a dashboard.
Through that Dashboard, the administrator can understand, manage and monitor the
database or any other targets. The second key feature is configuration management.
So OEM provides a centralized repository which stored the information about the
different targetsAnd with that information, we'll be able to, Manage the different
targets and we can enable the standard, we can enable the compliance.
So a lot of things related with the management of the resources can be done with
the help of the OEM. And another feature of OEM is provisioning and patching.
One of the recursive tasks for any database administrator or the operating system
administrator or even within the application administrator will be the patching.
So whenever a new changes are happening to the database or to the software component,
or if there is a security vulnerability to the software components, then we need
to apply the patches And OEM provides a centralized option where in which you can
apply the patches to different databases or the operating system system.
OEM Provisioning.
So you can have a gold image. Just considering the example of a database,
you can apply the patches or the security patches, CPU patches etcetera to an Oracle
home, make it that is a gold image and use that gold image for installing into
different other host. So provisioning and patching is one of the key feature of OEM.
Automation.
Self-service provides a different facility where in which a lot of repetitive tasks can be automated.
So, for example, you wanted to regularly, periodically you wanted to remove the old files, trail
files, etc. so you can create a job from the OEM and OEM will do that activity on multiple hosts so
a single script can be deployed across different targets or different operating systems, and then you
can run the scripts against different targets.
Security and compliance.
So OEM help us to create the user, audit the users and make sure that the users are in compliance with
the security standards.
You can create the database firewall, you can control the user accesses and also you can generate the
compliance report.
The last key feature is a cloud management.
OEM offers the capability to manage the Oracle software environments in both on premise as well as in
the cloud.
So you can use you can extend the features of OEM to the cloud environment as well.
Even you can manage the cloud databases with the help of the OEM.
The key features of OEM is monitoring and diagnosis.
Configuration Management Provisioning and patching.
Automation and Self Services.
Security Compliance.
And then cloud management.
So in nutshell, OEM provides a lot of features which will help us to manage and monitor the different
software solutions provided by Oracle, as well as some other key vendors like Microsoft.
thanks,
