Oracle Enterprise Manager Cloud Control: Write Powerful Scripts with EMCLI

Last week, I attended the Oracle Open World and did a presentation about writing scripts with EMCLI. If you’re not familiar with EMCLI, it’s the command line interface for Oracle Enterprise Manager Cloud Control. Here’s my presentation:

Although EMCLI is a very specific topic which appeals only to advanced users, a lot of people attended my session. I would like to thank Ray Smith (IOUG Director (more...)

EM13c: Unique Database Service Names on DBaaS

When creating Database through Oracle Enterprise Manager Self Service Portal, we need to enter a “unique” value as database service name. After I set up DBaaS on EM13c, I made several tests until I fix the provision problems (based on my own faults). On each test, I cleaned up failed request, entered a unique service name and submitted a new request. I thought there’s no validation about the service name but then I got an (more...)

Speaking at OOW 2016: Write powerful scripts with EMCLI

This will be my first time to attend Oracle Open World, and I’ll speak about Enterprise Manager Command-Line Interface (EMCLI) Scripting” on User Group Sunday. I already presented it on several conferences, heard people’s feedback and modified the content to improve my presentation. Now I will focus more on practical information, share sample scripts that can be used in real world scenarios. Hope to see you there!

EM13c: Performance Tuning Access to Read Only Administrators

About six months ago, when I was in the OUGN Spring Conference, someone asked me how they can let developers access to performance tuning pages on Enterprise Manager Cloud Control 13c. He said that they granted full administrator privileges to the developers so they could access the performance page but it’s not acceptable. He also mentioned that they didn’t need to grant full administration privilege to the developers’ EM users while they were using (more...)

How to Import Data (to Oracle RDBMS) from XML

I wrote a blog post about how to import data from a XML file to Oracle about 7 years ago. I demonstrated how we can use DBMS_XMLSTORE package to parse XML data. Yesterday, I replied a question from a blog reader about that post. He had problem with running my sample script, I did troubleshoot and find out the problem with his script, and while testing the sample script, I noticed that I can write (more...)

Book Review: Oracle Database Cloud Cookbook with Oracle Enterprise Manager Cloud Control 13c

13cCoverLatest Last week, I had a chance to read the latest book of my friend Porus Homi Havewala. If you’re interested in Oracle Enterprise Manager, you already knew him or at least read one of his articles/blog posts. He’s a Subject Matter Expert (SME) on Oracle Enterprise Manager Technology, Oracle Certified Master (OCM) and Oracle ACE Director. Porus created one of the world’s first blogs dedicated to Enterprise Manager (http://enterprise-manager.blogspot.com), and he (more...)

Oracle Enterprise Manager Plugin for PostgreSQL

Oracle Enterprise Manager supports 3rd party plugins which can help you to extend its monitoring and manageability capabilities. There are already developers and companies specialized in plugin development. Blue Medora is one of them (and probably the most famous one). In this blog post, I’ll show you how we can use Blue Medora’s EM PostgreSQL plugin, which is part of their True Visibility Suite for Oracle. I’ll download and deploy the plugin on the OMS (more...)

Installing EM13c Agents on Microsoft Windows Target Hosts

If your EM13c OMS installed on Unix-based OS, and want to deploy agents to Windows servers, you need to install Cygwin to target windows server to use regular deployment process. You can also use PsExec utility but in this case, you need a Microsoft Windows staging server. Installing Cygwin to enable SSH on Windows may sound like an unnecessarily complex solution at first, but Cygwin is easy to install and it comes with lots of (more...)

How to Modify the Retention Time for Metric Data in EM13c

Some Enterprise Manager customers, complain about the high volume of data stored in OMS repository. Enterprise Manager agents collect metric data of targets they monitor, and upload these “raw” metric data to OMS. Depending on your metric collection periods and number of targets, the volume required to keep these data can be very huge. Enterprise Manager has already a mechanism to minimize the size of the Management Repository. Once a day, the previous day’s metric (more...)

BGOUG Spring Conference 2016 & Twitter Statistics

As I already mentioned in my previous blog post, I attended the BGOUG (Bulgarian Oracle User Group) Spring Conference last week. It was my second time to attend BGOUG conferences, and as usual, it was a great organization. I’m really impressed how Milena Gerova and BGOUG Conference Team can organize such a successful event.

At the conference, I gave two speeches, one was “Linux Essential Commands for DBAs”, and the other one was “Oracle Enterprise (more...)
