EM13c: How to Disable Autodiscovery (and Autopromotion) of Clusterware Managed Targets

After we upgraded EM13c, I encountered a problem about automatically promoted listener targets. Since EM12c, I do not add/promote listeners. In earlier versions of EM12c, I had weird problems while monitoring listeners on RAC systems (such as they are detected down although they’re up). Since then, I don’t monitor them (specially SCAN listeners). In EM12c, when I remove a listener, it doesn’t promoted again. With EM13c, I see that listeners are discovered and promoted automatically (more...)

Which Management Packs are Required for Using the Notifications Feature from Cloud Control?

Sending notification emails shouldn’t require any licenses right? Unfortunately it might be more complicated than it seems

As you know Enterprise Manager Cloud Control provides a web interface called web console, and (naturally) it consists of web pages that enables you to access the features of Enterprise Manager Framework. Some of these features (mostly the basic ones) are free but some of them require you to buy management pack licenses. When you’re not sure if (more...)

Enterprise Manager Cloud Control 13c Initial Setup Console

When I was trying to discover the new features of EM13c, I noticed that EM13c provides you a new console called the Initial Setup Console. If you’re new to Enterprise Manager, you may wonder if you configured EM properly. The initial setup console is a great starting point to set up Enterprise Manager Cloud Control. You can reach this console under the setup menu.

How to Upgrade Oracle Enterprise Manager Cloud Control 12c to EM13c

You have probably heard that Oracle released Enterprise Manager Cloud Control 13c on Friday. It’s the first product from Oracle with the number 13 in its release label. It seems Oracle doesn’t care about the bad luck of 13 :) The new version comes with great features and maybe the most significant one is the unification of hardware and software management. In Oracle Enterprise Manager 13c, some of the important hardware management features of “Ops Center” (more...)

My Presentations at DOAG & BGOUG: EMCLI Crash Course

Last week, I gave presentations at DOAG (German Oracle User Group) conference and BGOUG (Bulgarian Oracle User Group) autumn conference about Oracle Enterprise Manager Command Line Interface. It was my first time at these conferences, and both of them were wonderful.

Before each session at DOAG Conference, there was a video showing “how they prepared the last year’s DOAG conference”. What a professionalism! What a great team work! You know Germany is known for their (more...)

Using EMCLI List Verb to Get Detailed Information of EM Targets

After the presentation about EMCLI at DOAG 2015, someone asked me how we can list database targets based on their operating systems. In my presentation, I told that there are more than 70 verbs which starts with “get_” and help you fetch information about EM objects, and if you can’t find what you’re looking for, you can use the “list” verb which is probably the most powerful verb of EMCLI. Now I try to show (more...)

EMCLI Python Script File to Create Users

I’ll give presentations at DOAG 2015 on Tuesday (tomorrow), and at the BGOUG Autumn Conference on Saturday. My presentation will be about EMCLI (Enterprise Manager Command Line Interface). I will try to explain the basics of EMCLI, its terminology, the important points, and how we can use it with bash for scripting. I’ll also speak about EMCLI Python scripting, very short but useful into to Python and then share some sample scripts. Because of the (more...)

How to Upgrade Sybase IQ 16 to 16.0.10 (SP10)

Sybase-IQ-Box-300x314Yesterday, I did my first Sybase IQ upgrade. I upgraded our main datawarehouse from Sybase IQ 16 to 16 SP10. The process was easy: Stop the database instance, install the new software, start the instance (from new software home), run an SQL to upgrade the metadata. Although the process was easy, I had some unexpected problems so I wanted to my notes in case you may need to upgrade your Sybase IQ.

You have probably (more...)

How to Download EM12c R5 Installation Files Using Wget

Although EM12c R5 (12.1.0.5) was released about 2.5 months ago, I couldn’t find time to upgrade our EM12c system until now. I have decided to dedicate my day for upgrading our EM12c. I’m not planning to write a step by step document because it’s already documented well by other bloggers. I’ll just share my notes if I encounter any problem.

I have probably told several times that EM12c should have some (more...)

Monitoring MongoDB using Oracle Enterprise Manager Cloud Control

Scott Wardrop from AIDEV told me that they produced a plugin for Oracle Enterprise Manager Cloud Control 12c to monitor MongoDB. We use MongoDB in our production systems, so I decided to examine the plugin and write a blog post about it. Unfortunately version of our MongoDB databases are too old (2.4.x series) so the plugin didn’t work. Of course, it didn’t stop me. We created a simple MongoDB Cluster environment to test (more...)
