Enterprise Manager 13c: What’s New in Database Lifecycle Management

Enterprise Manager 13c: What’s New in Database Lifecycle Management

A month back, we announced the release of Enterprise Manager 13c. Enterprise Manager 13c includes several improvements over Enterprise Manager 12c, which was itself had witnessed pretty successful adoption over the last four years. Enterprise Manager 12c rested on the key themes of enterprise grade management, stack management and cloud lifecycle management. The 13c version simply bolsters those pillars.

In the area of database lifecycle management, we have delivered some key features that span both the depth and the width of the data center. In terms of depth, it leverages the unification of hardware and software management to manage Exadata better. In terms of width, it offers simpler and more scalable cloud management. Over the next few paragraphs, I will touch upon few features that highlight the above.

Exadata Patching:

The patching of Exadata has been laborious process for our key customers. It involves multiple components across multiple nodes and often multiple administrators in the process. In Enterprise Manager 13c, some of the important hardware management features have been assimilated into the Cloud Control product. In course 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. For example, Enterprise Manager can now patch an Exadata stack- storage servers , Infiniband drivers, compute nodes, grid infrastructure and as before, the databases on top. 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).

Enhancements in Database Compliance Management:  

There have been some significant enhancements in database compliance management. These include:

a) Integration of Oracheck: A long-standing requirement that should thrill Exadata customers is the integration of Oracheck (including Exacheck) into the Compliance framework of Enterprise Manager. Exacheck had formerly existed as a standalone utility, but customers have asked for at-scale execution over all the Exa’s in a data center, with the ability to flag, suppress or escalate any violation. They can also generate reports on overall health and share with other administrators and IT Managers.

b) Integration with corrective action: Another much sought-after feature has been to integrate the compliance violations with corrective action. For example, a DBA may want to lock an account with default username and password. Enterprise Manager 13c makes this a reality.

Configuration Drift and Consistency Management:

When it comes to managing a cloud horizontally at scale, the configuration comparison feature of Enterprise Manager has always been a DBA’s favorite. The new configuration drift management feature evolves the feature further by enabling administrators to proactively spot the “needle in the haystack” among the hundreds and thousands of members that can be a part of a cloud or even span multiple clouds (example, on-prem and Oracle Cloud). The DBA can set up a golden standard with a selected list of configuration parameters and make sure that all the members of a cloud or a pool of databases subscribe to that standard. In case of any deviation, the DBA will be automatically notified. The consistency management can be applied across the different phases of lifecycle (for example, the test database should be the same as production) or across the different members of a system (for example, all the nodes of an Exadata should be exactly alike).
