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. 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.
In terms of cloud management, the release focuses on three key aspects: the ability to perform database consolidation planning for various scenarios, the ability to manage configuration drifts at scale and improved data lifecycle management across production and test instances.
The new Consolidation Workbench provides an end-to-end workflow that provides three distinct steps:
- What-if analysis on various consolidation scenarios: commodity to engineered systems, non-multitenant to multitenant databases and on-prem to Oracle Cloud.
- The actual enactment of the consolidation by integrating with the provisioning features
- Post-consolidation testing using the SQL Performance Analyzer
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.
It would be an incomplete disclosure to limit Oracle Enterprise Manager 13c’s capabilities to the above features. There are many more new features (see the full list) as well as hundreds of enhancements introduced into the existing features. I am certain that IT administrators and consultants would be looking for a top-12 feature list. For them, here’s the summary:
Gold image based agent lifecycle management (view screenwatch)
- “Always on” monitoring (view screenwatch)
- Notification blackouts for managing target downtime windows (view screenwatch)
- Cloud-scale configuration drift management
- Hardware and infrastructure management (view screenwatch)
- Engineered Systems patching
- Exadata and Exalogic-Nimbula VM provisioning
- Exacheck integration into the compliance framework
- Flexible access control for database management (view screenwatch)
- Database Consolidation workbench (view screenwatch)
- Continuous data refresh between production and test databases
- Unification of Middleware Consoles into Enterprise Manager 13c (view screenwatch)
To summarize, Enterprise Manager 13c reinforces its ability to manage along two dimensions: vertically across the stack, and horizontally, within and across clouds. So, number 13 indeed sounds lucky for Enterprise Manager customers, right?
