Oracle Enterprise Manager 13c is the latest release of Oracle on enterprise side. This release enable lot of new interesting to ease the administration,migration and monitoring.
Top new features are
1. Gold image based agent lifecycle management
Enterprise Manager administrators spend a lot time on various agent life cycle operations starting from a fresh installation through upgrade and patching. These tasks are even more challenging if you manage over 100 agents, ensuring they are all on the same patch level. Gold image-based agent lifecycle management simplifies the agent lifecycle process by using images of a gold agent to:
1)Provide auto-recovery from agent upgrade and agent plug-in deployment or upgrade
2)Ensure zero downtime for agent maintenance including patching, upgrade, and plug-ins
3)Providing standardized agent configurations
4)Provision, upgrade, and update Agents and plug-ins in a highly scalable approach
5)Create from live test agent patched and updated with required plug-ins
6)Export/import the gold image (test agent) from Test to Enterprise Manager Production
7)Promote gold images based on maturity level (Prod, Test)
8)Provide Oracle supplied gold agent image and configurations through Self Update
9)Report to show distribution of agents deployed with gold images
10) Pick configuration data from source agent emd.property file
2. “Always on” monitoring
Oracle Enterprise Manager today is the nerve center of IT operations among thousands of enterprises, our very own public cloud operations being one among them. Millions of assets in Oracle’s SaaS and PaaS public cloud operations are managed by Enterprise Manager round the clock, which requires that Oracle Cloud’s own Oracle Enterprise Manager instance stays up and running during unplanned and planned downtime windows. Oracle Enterprise Manager 13c therefore introduces “always on” monitoring, where a small companion monitoring application continues to receive critical alerts from the agents out-of-band while the management server is down. One can start the application, take Oracle Enterprise Manager down for patching and continue to be alerted on critical events. Speaking of planned downtime windows, another exciting feature being introduced is “notification blackouts”, which lets administrators monitor their targets during their maintenance windows, while notifications from critical alerts are still turned off.

4. Cloud-scale configuration drift management
The new configuration drift management feature enables administrators to proactively spot the “needle in the haystack” among the hundreds and thousands of members that can constitute a cloud or even across multiple clouds. And last but not the least, Snap Clone customers would be benefited by the ability to keep the test databases in sync with their production.
5. Hardware and infrastructure management
When it comes to stack management, the BIG news for our customers is the unification of hardware and software management. Ever since Oracle acquired Sun, we have promised a converged systems management, but current customers have been managing hardware through a separate tool called Ops Center. In Oracle Enterprise Manager 13c, some of the important hardware management features have been assimilated into the Cloud Control product. This not only benefits platform administrators in that they can now drill down into the infrastructure problems easily, this also benefits system and storage administrators because they can enjoy the scalability, availability and security framework features of Cloud Control. As an example, critical incidents in the hardware layer can now be published to a 3rd party ticketing system using the connector framework, something that Oracle hardware customers have asked for a long time. As part of developing the hardware aka the infrastructure management features, we have modeled the infrastructure target types: servers, storage, network, VMs in Enterprise Manager. This also enables us to have a more sophisticated management of Engineered Systems, including the ability to patch a complete Exadata and Exalytics stack. The patching application offers the facility to run the pre-flight checks and monitor the logs from a single place (imagine having to manually monitor the patch execution logs for grid infrastructure, operating system, storage for all the compute and storage cells in a rack). Another enhancement that should thrill Engineered Systems customers is the integration of Exacheck into the Compliance framework of Enterprise Manager; this would let them generate automated notifications and reports for any violation in their Exadata configurations.
6. Engineered Systems patching
Complete patching automation for Exadata and Exalytics including features like patch recommendations, auto patch download, scheduled application, granular status tracking, log monitoring and aggregation. Patches can be applied to all or a subset of components providing extreme flexibility.
Automating the application of the quarterly patches will save significant time and reduce errors by ensuring pre-requisite steps and procedures are properly followed, and by applying the component patches in the correct sequence.
7. Exadata and Exalogic-Nimbula VM provisioning
The Exadata plug-in has been enhanced to support the lifecycle management of an Exadata 18.104.22.168.0 virtualized environment. VM provisioning on Exadata provides an efficient, completely automated mechanism for scheduled mass deployment of RAC databases. Administrators can now perform the following active management operations from the Exadata target home page to meet on demand or planned capacity needs:
•Create and delete RAC databases including VMs
•Extend existing clusters (grid infrastructure) including VMs
•Scale down cluster and deprovision VMs
8. Exacheck integration into the compliance framework
9. Flexible access control for database management
One request we always received from our database customers was to enable fine grain access control. Most organizations have multiple personas (Central DBAs, application DBAs, Developers, etc) and would like segregation of duties among these personas. For example, a Developer may be allowed to tune the application but not patch the underlying database. Oracle Enterprise Manager 13c enables fine grained privileges for controlling access to specific features.
10. Database Consolidation Workbench
This is a tool that provides the ability to perform database consolidation planning for various scenarios. It provides an end-to-end workflow comprised of three main parts:
1)What-if analysis on various consolidation scenarios: commodity to engineered systems, non-multitenant to multitenant databases and on-premises to Oracle Cloud.
2)The actual consolidation process by integrating with the relevant provisioning functionality
3)Post consolidation testing to ensure there is no regression, using SQL Performance Analyzer (more commonly known as SPA)
11. Continuous data refresh between production and test databases
12. Unification of Middleware Consoles into Enterprise Manager 13c

Oracle Enterprise Manager Grid Control can be used to manage various oracle deployment. It can manage multiple instances of Oracle deployment platforms; the most recent edition also allows for management and monitoring of other platforms such as Microsoft .NET, Microsoft SQL Server, NetApp Filers, BEA weblogic and others.It also provides Monitoring. System monitoring features include monitoring functionality that supports detection and notification of impending IT problems. It monitors Oracle Database instances, Oracle Real Application Clusters, and Oracle Application Server Farms and Clusters. OEM Grid Control comes with a set of performance and health metrics that allow monitoring of technology components such as applications, application servers, databases, as well as the back-end components on which they rely, such as hosts, operating systems and storage.
The architecture of the OEM for Grid Control has three distinct components:
1)the collection agent (Oracle Management Agent or OMA)
2) the aggregation agent (Oracle Management Server or OMS)
3) the repository agent (Oracle Management Repository or OMR)
How it works
The OMA runs on the target host and collects information on the hardware, operating system, and applications that run on the target. The OMS runs on one or two servers and collects the data generated by the OMAs. The OMS pulls the information from the OMAs and aggregates the collections into the repository. The OMS also acts as the user-interface — by generating web-pages for database administrators to view the status of systems and services. The OMR comprises an instance of the Oracle database that stores the data collected by the OMS. Installers can make the OMR highly available or fault-tolerant by running it on an Oracle RAC instance across multiple nodes.
How to customize it
Plug-ins on each of the OMAs can customise or manipulate the data presented by the OEM by extending the data that the OMAs collect. Administrators can customize the analysis of the data with “management packs” to look at specific collections of data to display a system’s performance. The current release of OEM allows for the design and configuration of custom Plug-ins to monitor any application desired. OMAs collect the data using the custom-built plug-in and transmit the results in XML format back to the OMS, which then stores and analyzes the data as desired.Oracle Enterprise Manager continues to expand its monitoring scope by offering management plug-ins for non-Oracle components, that are both Oracle-developed and developed in partnership by third-party vendors. For example, Plug-ins for Veritas Storage Foundation, VMWare vSphere, and EMC Clariion are available.
