Database patch management process

Enterprise Manager 12c Release 3 includes improvements and enhancements across every area of the product. This blog provides an overview of the new and enhanced features in the Database Lifecycle Management area. I will deep dive into specific features more in depth in subsequent posts.

"What's New?" In this release, we focused on four things:

1. Lifecycle Management Support for new Database12c, especially around the pluggable databases (aka multitenant option)

2. Management of long running processes, such as a security patch cycle (Change Activity Planner)

3. Management of large number of systems by

· Leveraging new framework capabilities for lifecycle operations, such as the new advanced ‘emcli’ script option

· Refining features such as configuration search and compliance

4. Minor improvements and quality fixes to existing features

· Rollback support for Single instance databases

· Improved "OFFLINE" Patching experience

· Faster collection of ORACLE_HOME configurations

Lifecycle Management Support for new Database 12c - Pluggable Databases

Database 12c introduces Pluggable Databases (PDBs), the brand new addition to help you achieve your consolidation goals. Pluggable databases offer unprecedented consolidation at database level and native lifecycle verbs for creating, plugging and unplugging the databases on a container database (CDB).

Enterprise Manager can supplement the capabilities of pluggable databases by offering workflows for migrating, provisioning and cloning them using the software library and the deployment procedures. For example, Enterprise Manager can migrate an existing database to a PDB or clone a PDB by storing a versioned copy in the software library. One can also manage the planned downtime related to patching by migrating the PDBs to a new CDB.

While pluggable databases offer these exciting features, it can also pose configuration management and compliance challenges if not managed properly. Enterprise Manager features like inventory management, topology associations and configuration search can mitigate the sprawl of PDBs and also lock them to predefined golden standards using configuration comparison and compliance rules.

Management of Long Running datacenter processes - Change Activity Planner (CAP)

Currently, customers resort to cumbersome methods to create, execute, track and monitor change activities within their data center. Some customers use traditional tools such as spreadsheets, project planners and in-house custom built solutions. Customers often have weekly sync up meetings across stake holders to collect status and updates. Some of the change activities, for example the quarterly patch set update (PSU) patch rollouts are not single tasks but processes with multiple tasks. Some of those tasks are performed within Enterprise Manager Cloud Control (for example Patch) and some are performed outside of Enterprise Manager Cloud Control. These tasks often run for a longer period of time and involve multiple people or teams.

Enterprise Manger Cloud Control supports core data center operations such as configuration management, compliance management, and automation. Enterprise Manager Cloud Control release leverages these capabilities and introduces the Change Activity Planner (CAP).

CAP provides the ability to plan, execute, and track change activities in real time. It covers the typical datacenter activities that are spread over a long period of time, across multiple people and multiple targets (even target types).
