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 - Pluggable
Databases
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 12.1.0.3
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).
Here are some examples of Change Activity
Process in a datacenter:
· Patching large environments (PSU/CPU
Patching cycles)
· Upgrading large number of database
environments
· Rolling out Compliance Rules
· Database Consolidation to Exadata
environments
CAP provides user flows for Compliance Officers/Managers (incl. lead
administrators) and Operators (DBAs and admins).
Managers can create change activity plans for various projects, allocate
resources, targets, and groups affected. Upon activation of
the plan, tasks are
created and automatically assigned to individual administrators based on target
ownership. Administrators (DBAs) can identify their tasks and understand
the
context, schedules, and priorities. They can complete tasks using Enterprise
Manager Cloud Control automation features such as patch plans (or in some cases
outside Enterprise Manager). Upon completion, compliance is evaluated for
validations and updates
the status of
the tasks and
the plans.

Improved Configuration & Compliance Management of a large number of systems
Improved Configuration Comparison:
Get to
the configuration comparison results faster for simple ad-hoc
comparisons. When performing a 1 to 1 comparison, Enterprise Manager will
perform
the comparison immediately and take
the user directly to
the results
without having to wait for a job to be submitted and executed.
Flattened system comparisons reduce comparison setup time and reduce
complexity. In addition to
the previously existing topological comparison,
users now have an option to compare using a “flattened” methodology. Flattening
means to remove duplicate target instances within
the systems and remove
the
hierarchy of member targets.
The result are much easier to spot differences
particularly for specific use cases like comparing patch levels between complex
systems like RAC and Fusion Apps.
Improved Configuration Search & Advanced EMCLI Script option for
Mass Automation
Enterprise manager 12c introduces a new framework level capability to be able to script and stitch together multiple tasks using EMCLI. This powerful capability can be leveraged for lifecycle operations, especially when executing a task over a large number of targets. Specific usages of this include, retrieving a qualified list of targets using Configuration Search and then using
the resultset for automation. Another example would be executing a patching operation and then re-executing on targets where it may have failed. This is complemented by other enhancements, such as a better usability for designing reusable configuration searches.
IN EM 12c Rel 3, a simplified UI makes building adhoc searches even easier. Searching for
missing patches is a common use of configuration search. This required
the use
of
the advanced options which are now clearly defined and easy to use.
Perform “Configuration Search” using
the EMCLI. Users can find and execute Configuration
Searches from
the EMCLI which can be extremely useful for building
sophisticated automation scripts.
For an example, Run
the Search named “Oracle Databases on Exadata” which finds all Database targets running on
top of Exadata. Further filter
the results by refining by options like name,
host, etc..
emcli get_targets -config_search="Databases on Exadata" –target_name="exa%“
Use this in powerful mass automation operations using
the new emcli script
option. For example, to solve
the use case of – Finding all DBs running on
Exadata and housing E-Biz and Patch them.
Create a Python script with emcli functions and invoke it in
the new EMCLI script
option shell.
Invoke
the script in
the new EMCLI with script option directly:
$<path to emcli>/emcli @myPSU_Patch.py
Richer compliance content:
Now over 50 Oracle Provided Compliance
Standards including new standards for Pluggable Database, Fusion Applications,
Oracle Identity Manager, Oracle VM and Internet Directory.
9 Oracle provided Real Time Monitoring Standards containing over 900
Compliance Rules across 500 Facets. These new Real time Compliance Standards covers
both Exadata Compute nodes and Linux servers.
The result is increased Oracle
software coverage and faster time to compliance monitoring on Exadata.
Enhancements to Patch Management:
Overhauled "OFFLINE" Patching experience: Simplified Patch uploads UI to improve
the offline experience of patching. There is now a single step process to get
the patches into
software library.
Customers often maintain local repositories of patches, sometimes called
software depots, where they host
the patches downloaded from My Oracle Support.
In
the past, you had to move these patches to your desktop then upload them to
the Enterprise Manager's
Software library through
the Enterprise Manager Cloud
Control user interface.
You can now use
the following EMCLI command to upload multiple patches directly
from a remote location within
the data center:
$emcli upload_patches -location <Path to Patch directory>
-from_host <HOSTNAME>
The
upload process filters all of
the new patches, automatically selects
the
relevant metadata files from
the location, and uploads
the patches to
software
library.
Other
Improvements:
Patch rollback for single instance databases, new option in
the Patch Plan to
rollback
the patches added to
the patch plans. Upon execution,
the procedure
would rollback
the patch and
the SQL applied to
the single instance Databases.
Improved
and faster configuration collection of Oracle Home targets can enable more
reliable automation at higher level functions like Provisioning, Patching or
Database as a Service.
