Simplified Agent and Plug-in Deployment

On your site of hundreds or thousands of hosts have you had to patch agents immediately as they get deployed?  For this reason I’ve always been a big fan of cloning an agent that has the required plug-ins and all the recommended core agent and plug-in patches, then using that clone for all new agent deployments. With EM 12c this got even easier as you can now clone the agent using the console “Add Host” method. You still have to rely on the EM users to use the clone. The one problem I have with cloning is that you have to have a reference target for each platform that you support. If you have a consolidated environment and only have Linux x64, this may not be a problem. If you are managing a typical data center with a mixture of platforms, it can become quite the maintenance nightmare just to maintain your golden images. You must update golden image agents whenever you get a new patch (generic or platform specific) for the agent or plug-in, and recreate the clone for each platform. Typically, I find people create a clone for their most common platforms, and forget about the rest. That means, maybe 80% of their agents meet their standard patch requirements and plug-ins upon deployment, but the other 20% have to be patched post-deploy, or worse – never get patched!

While deployed agents and plug-ins can be patched easily using EM Patches & Updates, but what about the agents still getting deployed or upgraded? Wouldn’t it be nice if they got patched as part of the deployment or upgrade? This article will show you two new features in EM 12.1.0.3 (12cR3) that will help you deploy the most current agent and plug-in versions. Whether you have 100s or 1000s of agents to manage, reducing maintenance and keeping the agents up to date is an important task, and being able to deploy or upgrade to a fully patched agent will save you a lot of time and effort.

Oracle-validated NetApp Storage Plug-in for Enterprise Manager 12c

The following is a Guest Blog, contributed by Anand Ranganathan, Product Manager for Oracle Products and Solutions at NetApp

As a DBA managing databases running on storage systems, some of your major challenges are how do you:

  • Pinpoint storage related problems in a timely manner
  • Proactively respond to problems
  • Map a database file to its underlying storage component
  • Reduce your dependency on the storage admin
  • Solve these problems using an Oracle product that you use everyday

If you are planning to or are currently running your Oracle databases on NetApp storage systems then the NetApp Storage System Plug-in for Oracle Enterprise Manager 12c resolves the above challenges by:

  • Consolidating information about Oracle on NetApp environments into the Enterprise Manager Cloud Control Console providing one interface to monitor databases and storage systems
  • Correlating and pinpointing storage related database problems by mapping database components like tablespaces, datafiles to storage components like aggregates, volumes using built-in reports and automating collecting a comprehensive set of availability, performance and usage metrics with pre-defined thresholds.  Alerts are automatically sent out when thresholds are breached helping you to respond proactively to problems before they occur.  You can also ensure routine responses to alerts are automatically executed using corrective actions
  • Increasing operational efficiencies by allowing you to standardize optimal Monitoring settings into a template and apply them to one or more NetApp Storage systems, report on historical metrics data for trend analysis & planning database storage needs, compare multiple storage system configurations to ensure they are deployed as per standards and prevent unnecessary alerts during scheduled downtimes with Blackout Periods

The plug-in was built by NetApp using the Enterprise Manager 12c Extensibility Kit that not only helped us develop screens that have a rich look and feel but also helped enrich the plug-in by allowing us to leverage Cloud Control’s powerful monitoring and event management features for monitoring of NetApp storage systems. 

The NetApp Storage System Plug-in for Oracle Enterprise Manager 12c is free and is listed at the Enterprise Manager Extensibility Exchange.  The plug-in has achieved Oracle Validated Integration, which provides customers the confidence knowing that it:

  • is designed and built in a reliable, standardized way
  • has been tested as functionally and technically sound
  • operates and performs as documented

Here is a screenshot of the dashboard of a NetApp storage system monitored with Enterprise Manager 12c via the NetApp plug-in.



Customers and partners can visit the NetApp Communities site to watch a demo and download the plug-in.  If you are a partner, visit the Oracle PartnerNetwork Validated Integration Knowledge Zone to learn more about the validation program.

Heterogeneous Datacenter Management with Enterprise Manager 12c

The following is a Guest Blog, contributed by Bryce Kaiser, Product Manager at Blue Medora

When I envision a perfect datacenter, it would consist of technologies acquired from a single vendor across the entire server, middleware, application, network, and storage stack - Apps to Disk - that meets your organization’s every IT requirement with absolute best-of-breed solutions in every category.   To quote a familiar motto, your datacenter would consist of "Hardware and Software, Engineered to Work Together".  

In almost all cases, practical realities dictate something far less than the IT Utopia mentioned above.   You may wish to leverage multiple vendors to keep licensing costs down, a single vendor may not have an offering in the IT category you need, or your preferred vendor may quite simply not have the solution that meets your needs.    In other words, your IT needs dictate a heterogeneous IT environment.  Heterogeneity, however, comes with additional complexity. The following are two pretty typical challenges:

1) No End-to-End Visibility into the Enterprise Wide Application Deployment. Each vendor solution which is added to an infrastructure may bring its own tooling creating different consoles for different vendor applications and platforms.

2) No Visibility into Performance Bottlenecks. When multiple management tools operate independently, you lose diagnostic capabilities including identifying cross-tier issues with database, hung-requests, slowness, memory leaks and hardware errors/failures causing DB/MW issues.

As adoption of Oracle Enterprise Manager (EM) has increased, especially since the release of Enterprise Manager 12c, Oracle has seen an increase in the number of customers who want to leverage their investments in EM to manage non-Oracle workloads.  Enterprise Manager provides a single pane of glass view into their entire datacenter.  By creating a highly extensible framework via the Oracle EM Extensibility Development Kit (EDK), Oracle has provided the tooling for business partners such as my company Blue Medora as well as customers to easily fill gaps in the ecosystem and enhance existing solutions.  

As mentioned in the previous post on the Enterprise Manager Extensibility Exchange, customers have access to an assortment of Oracle and Partner provided solutions through this Exchange, which is accessed at http://www.oracle.com/goto/emextensibility.  Currently, there are over 80 Oracle and partner provided plug-ins across the EM 11g and EM 12c versions.  Blue Medora is one of those contributing partners, for which you will find 3 of our solutions including our flagship plugin for VMware.  

Let's look at Blue Medora’s VMware plug-in as an example to what I'm trying to convey.  Here is a common situation solved by true visibility into your entire stack:

Symptoms
•    My database is bogging down, however the database appears okay internally.  Maybe it’s starved for resources?
•    My OS tooling is showing everything is “OK”.  Something doesn’t add up.

Root cause
•    Through the VMware plugin we can see the problem is actually on the virtualization layer

Solution
•    From within Enterprise Manager  -- the same tool you use for all of your database tuning -- we can overlay the data of the database target, host target, and virtual machine target for a true picture of the true root cause.

Here is the console view:


Perhaps your monitoring conditions are more specific to your environment.  No worries, Enterprise Manager still has you covered.  With Metric Extensions you have the “Next Generation” of User-Defined Metrics, which easily bring the power of your existing management scripts into a single console while leveraging the proven Enterprise Manager framework.

Simply put, Oracle Enterprise manager boasts a growing ecosystem that provides the single pane of glass for your entire datacenter from the database and beyond.
