This last week I presented at Great Lakes Oracle Conference, (GLOC16) and the discussion on monitoring of non-Oracle databases came up while we were on the topic of management packs, how to monitor usage and what ones were required to monitor non-Oracle databases.  I didn’t realize how confusing the topic could be until I received an email while in on layover in Chicago and relaying what the attendee had taken away from it.  I was even more alarmed when I read the email again, planning to blog about it today after a full nights sleep!

You’ll often hear me refer to EM13c as the single-pane of glass when discussing hybrid cloud management, performance management when concerning AWR Warehouse and such, but it also can make a multi-platform environments easier to manage, too.

The difference between managing many Oracle features with EM13c and non-Oracle database platforms is that we need to shift the discussion from Management Packs to Plug-ins.  I hadn’t really thought too much of it when I’d been asked what management packs were needed to manage Microsoft SQL Server, Sybase or DB2.  My brain was solely focused on the topic of management packs and I told the audience how they could verify management packs on any page in EM, (while on the page, click on Settings, Management Packs, Packs Used for This Page) for any database they were monitoring:

em13c_mssql

As easily demonstrated in the image above, there aren’t any management packs utilized to access information about the MSSQL_2014 Microsoft SQL Server and you can quickly see each of the User databases status, CPU usage, IO for read and writes, along with errors and even control the agent from this useful EM dashboard.

I can do the same for a DB2_unit6024 database environment:

em13c_sybase

You’ll note that the DB2 database dashboard is different from the SQL Server one, displaying the pertinent data for that database platform.

Now, you may be saying, Kellyn’s right, I don’t need to have any management packs, (which is true) but then you click on Settings, Extensibility, Plug-ins and you’ll then locate the Database Plug-ins used to add each one of these databases to the Enterprise Manager.

em13c_dbplugins

These plug-ins are offered often by third parties and must be licensed through them.  There may be and are often charges from these providers and I should have been more in-tune to the true discussion and not stuck on the topic of management packs.

Luckily for me, there is a small amount of explanation on the very bottom of the management pack documentation that should clear up any questions. Hope this offers some insight and thank you to everyone who came to my sessions at GLOC!

Licensing can be a confusing topic for many, but additional stress can be felt for those that use tools that cover multiple products and features that can span more than one management pack.

I’ve demonstrated how you can see what management packs are used and how to control this via EM13c, (also available in EM12c) but that can take you away from the task at hand.  That’s where turning on Annotations for Management Packs may be beneficial.

Annotations

What are annotations and why use them?

annot2

For Enterprise Manager 13c, this results in initials for management packs placed after feature drop down menus throughout the interface.

Enabling Annotations

Turning this feature on is very easy.  Click on Settings, Management Pack and then Annotations.

annot1

Once this is enabled, your drop down menus will look a little different than they did previously, as the annotations will be added for the management pack(s) used by the feature.  This is for both the upper right hand drop down from Enterprise to Settings and then the lower left menu, from the main Target Type and across.

To give an example, lets say we’ve logged into a database target and clicked on Performance.  We’d now see the annotations for the management packs used for first section of options:

annot3

We quickly recognize the Database Diagnostics, (DD) and Database Tuning, (DT) Pack annotations next to each of the features.

Mission Impossible Quiz

Let’s take one of the drop downs from the Enterprise Menu with the annotations turned on.  From Enterprise, Configuration, can you tell what management packs are being used outside of DBLM, (Database Lifecycle Management) in the list below?

annot4

There’s a lot of acronyms and initials there and hint, hint… I already showed you how to find out this information earlier, so take your time, I’ll wait right here…. 🙂

Have a great weekend!

There was a question posted on Oracle-l forum today that should have a blog post for easy lookup for folks.  Regarding your Enterprise Manager repository database, (aka OMR.)   This database has a restricted use license, which means you can use it for the Enterprise Manager repository, but you can’t add partitioning to it or RAC or dataguard features without licensing those features.  You also can’t use the diagnostic and tuning pack features available in Enterprise Manager on the repository database without licensing it outside of the EMDiagnostics tool.  You can view information about the license that is part of the OMR here.

No one wants to be open to an audit or have a surprise when inspecting what management packs they’re using.

To view what management packs you’re using for any given EMCC page, you can use the console and access it from the Setup menu from EM12c or EM13c:

mgmt_pack

With that said, Hans Forbrich made a very valuable addition to the thread and added how to disable EM management control access in your OMR database-

Run the following to disable it via SQL*Plus as SYSDBA:

ALTER SYSTEM SET CONTROL_MANAGEMENT_PACK_ACCESS='NONE' scope=BOTH;

Other packs are disabled using the EM Cloud Control with the appropriate privileges in the console using the SETUP menu in 12.1.0.4 with a patch or higher:

mgnt_pck_acs

The view can be changed from licensed databases to all databases and then you can go through and adjust management packs as licensed and then apply.

mngt_acs_2

Don’t make yourself open to an audit when Enterprise Manager can make it really easy to manage the management packs you are accessing.
