Updated 12c OCP upgrade Self Test software has more questions

Bobby Durrett's DBA Blog - Fri, 2014-05-30 17:17

I guess I should have waited around a bit longer before taking my 12c OCP upgrade exam.  I purchased Kaplan’s Self Test software to prepare for the 12c OCP upgrade exam but it only included 50 questions and they only covered the first part of the OCP exam – the part I passed!

I noticed on the Self Test website that the test now includes 105 questions.  So, I got the bright idea of seeing if there was some way to refresh my software with an update and voilà! Now I have 105 questions and 128 flash cards.  Probably I should have waited for this practice software to mature before attempting the 12c OCP upgrade test.  One thing of particular interest to me is that it does include practice questions related to the second part of the exam which I failed.

So, hopefully I’ll be in good shape for the retest.  I am doing a lot of hacking around with different features but I need to figure out a more methodical way to study.  Still, having taken the test once I know some of the features that I need to study.  Combine that with the new questions on the Self Test software and that will get me closer.  Lastly, I pre-ordered Sam Alapati’s book on Amazon so that should put me over the top.  I was really only two questions away on my first attempt but I definitely should have waited and have done more thorough preparation.

First draft Sudden SQL Slowness Toastmasters talk

Bobby Durrett's DBA Blog - Thu, 2014-05-29 15:23

I’m doing Toastmasters to try to improve my speaking and my third talk will be related to why a function on a web site can suddenly slow down due to a change in plan.  It has to be 5 to 7 minutes long and the audience is non-technical.

So, just for fun, here is my first draft.  If you feel like giving me any suggestions that would be great.

From Las Vegas to Ottawa

Pakistan's First Oracle Blog - Wed, 2014-05-28 21:16
After a very engaging session at Collaborate14 in sunny Las Vegas amidst the desert of Nevada, I just arrived in not-so-bitterly cold Ottawa, the capital of Canada. Looking forward meeting with various Pythian colleagues and hanging out with the friends I cherish most.

My Exadata IORM session went well. Lots of follow back discussion plus questions are still pouring in. I promise I will answer them as soon as I return to Australia after couple of weeks. That reminds me of my flight from one corner of the globe to the other, but well I need to learn as how to sleep like a baby during flights. Any ideas?

Ottawa reminds me of Australian capital Canberra. It's quite a change after neon-city Vegas. Where Vegas was bathing in lights, simmering with shows, bubbling with bars, swarming with party-goers, and rattling with Casinos; Ottawa is laid-back, quiet, peaceful, and small. Restaurants and cafes look cool. Ottawa River is mostly still frozen and mounds of snow are evident along the road sides with leafless trees.

But spring is here, and things look all set to rock.

Tackling the challange of Provisoning Databases in an agile datacenter

Pankaj Chandiramani - Wed, 2014-05-14 01:03

One of the key task that a DBA performs repeatedly is Provisioning of Databases which also happens to one of the top 10 Database Challenges as per IOUG Survey .

Most of the challenge comes in form of either Lack of Standardization or it being a Long and Error Prone Process . This is where Enterprise Manager 12c can help by making this a standardized process using profiles and lock-downs ; plus have a role and access separation where lead dba can lock certain properties of database (like character-set or Oracle Home location  or SGA etc) and junior DBA's can't change those during provisioning .Below image describes the solution :



In Short :



  • Its Fast

  • Its Easy 

  • And you have complete control over the lifecycle of your dev and production resources.


I actually wanted to show step by step details on how to provision a 11204 RAC using Provisioning feature of DBLM  , but today i saw a great post by MaaZ Anjum that does the same , so i am going to refer you to his blog here :

EMCLI setup

Pankaj Chandiramani - Mon, 2014-04-28 02:15

A quick note on how to install EMCLI which is used for various CLI operations from EM . I was looking to test some Database provisioning automation via EMCLI and thus was looking to setup the same . 


EMCLI Setup
To set up EMCLI on the host, follow these steps:
1.    Download the emcliadvancedkit.jar from the OMS using URL https://<omshost>:<omsport>/em/public_lib_download/emcli/kit/emcliadvancedkit.jar
2.    Set your JAVA_HOME environment variable and ensure that it is part of your PATH. You must be running Java 1.6.0_43 or greater. For example:
o    setenv JAVA_HOME /usr/local/packages/j2sdk
o    setenv PATH $JAVA_HOME/bin:$PATH
3.    You can install the EMCLI with scripting option in any directory either on the same machine on which the OMS is running or on any machine on your network (download the emcliadvancedkit.jar to that machine)
java -jar emcliadvancedkit.jar client -install_dir=<emcli client dir>
4.    Run emcli help sync from the EMCLI Home (the directory where you have installed emcli) for instructions on how to use the "sync" verb to configure the client for a particular OMS.
5.    Navigate to the Setup menu then the Command Line Interface. See the Enterprise Manager Command Line Tools Download page for details on setting EMCLI.

Webcast: Database Cloning in Minutes using Oracle Enterprise Manager 12c Database as a Service Snap Clone

Pankaj Chandiramani - Thu, 2014-04-17 04:02

Since the demands
from the business for IT services is non-stop, creating copies of production
databases in order to develop, test and deploy new applications can be
labor intensive and time consuming. Users may also need to preserve private
copies of the database, so that they can go back to a point prior to when
a change was made in order to diagnose potential issues. Using Snap Clone,
users can create multiple snapshots of the database and “time
travel
” across these snapshots to access data from any point
in time.


Join us for an in-depth
technical webcast and learn how Oracle Cloud Management Pack for Oracle
Database's capability called Snap Clone, can fundamentally improve the
efficiency and agility of administrators and QA Engineers while saving
CAPEX on storage. Benefits include:



  • Agile provisioning
    (~ 2 minutes to provision a 1 TB database)

  • Over 90% storage
    savings

  • Reduced administrative
    overhead from integrated lifecycle management
