Modifying BI Publisher reports in Oracle Enterprise Manager 13c, e.g. ‘Database Usage Tracking Summary’;

By | February 27th, 2016|Categories: Oracle Enterprise Manager|Tags: , , |

Recently I bumped into an annoying bug in the code of a report, wrote about it a while ago, notified Oracle. And they has confirmed that a new version of this specific report is in development phase.

But.. a report can be modified, so if it’s not that hard, why wait for a patch when you want to use a report you need in the meantime? It is is not advisable to modify a standard report, because undoubtedly there will be other changes in a patch to come (e.g. the datamodel), but as long you are aware of this…..

So I chose to modify my favourite report ‘Database Usage Tracking Summary’ for this blog.  And it turned out to be surprisingly simple.


Oracle Public Cloud Confusion

By | February 19th, 2016|Categories: Uncategorized|Tags: , |

I always thought I could address the main differences between private and public cloud. Oracle announced the ‘Oracle Private Cloud Machine’ at Oracle Open World 2015 which runs locally, offering a private cloud for an organization. Then Oracle decided to rename it to ‘Oracle Public Cloud Machine’.

And I think a public cloud has two important aspects: (1) resources are shared by multiple organizations and (2) services are available through a public network.

Does this new name make any sense? Where does this machine fit in? Is Oracle trying to change the definition of ‘public cloud’? They already renamed the ‘Oracle Virtual Compute Appliance’ to ‘Oracle Private Cloud Appliance’. This post is just a short reflection of my land of confusion.


Usage Tracking Reports, using Oracle Enterprise Manager 13C as a SAM tool

By | February 4th, 2016|Categories: Architecture, licensing, Oracle Enterprise Manager|Tags: , , , |

Still loving the idea to use Oracle Enterprise Manager as a ‘kind of ‘ Software Asset Management Tool, and get regular centralized reports that tells me what Oracle software is running and if there are changes in use of licenses over time. The necessary data is already there in the OEM repository, so there should be standard report facilities to get me informed (other then my own sql-reports from the repository). And guess what, these reports are available.

The Usage Tracking Reports, including the two reports which are important for monitoring the use of licensing, were already present in OEM 12C (wrote about it a while ago) , and I was curious if the usability and functionality improved in OEM 13C (as told me at the demogrounds of OOW2015..).


Implementing ORAchk in Oracle Enterprise Manager 13c

By | February 3rd, 2016|Categories: Database, Meta-DBA|Tags: , |

Heard about it at Oracle OpenWorld 2015: A new feature in Oracle Enterprise Manager 13c is the possibility to incorporate ORAchk, the healthcheck tool for databases, RAC and Engineered Systems.

This post is about downloading (and importing), deploying and provisioning the ORAchk-plugin. Spoiler-alert: there’s downtime involved of the OMS.

There are two ways for downloading and deploying : offline-patching and on-line, which means whether OEM is connected to My Oracle Support or not. In this post I will describe both methods ( every method by the way with varying success). And of course you can choose between using the command-line EMCLI and the graphical user interface. It’s Enterprise Manager, so mainly using the gui, but sometimes  forced to use the command-line.


Oracle OpenWorld 2015 – a customer’s perspective

By | February 2nd, 2016|Categories: Architecture, Database|Tags: , , |

At the start of the each year, I always take the time to look back on the year we left behind. Last year, one of my most memorable experiences was Oracle OpenWorld in San Francisco. The event has always been an overwhelming experience, but this year it seemed even more so. I have never experienced such an amount of announcements and innovations, varying in importance and readiness, and all more or less related to the cloud.

A massive technology push to the cloud, a ‘cloud overload’. That could be the management summary of Oracle Open World 2015 (OOW15).

Oracle as software vendor is evolving to a cloud service provider. The force is strong….


Keeping track of Oracle licenses with OEM12c – reports

By | May 16th, 2015|Categories: Database, licensing|Tags: , , |

Wouldn’t be nice to get regularly informed how (in)compliant you are with Oracle licenses in an easy – centralized – way, and therefore not have to worry about visits of Oracle’s LMS – License Management Services? I think that would be nice for the most of us. Running LMS-scripts on the target databases, hosts and middleware is for now the most thorough way to get informed about possible incompliancy. Or in some cased,  using some clever – but informal and mostly incomplete – scripting on the OEM-repository.

But… Oracle is making serious attempts to make this easier, by integrating the LMS-information  in the repository of Oracle Enterprise Manager and make this available through a couple of (BI Publisher) reports:

  • Database Usage Tracking Report
  • Database Usage Tracking Summary Report

When running these reports (Enterprise –> Reports  -> BI Publisher Reports) with OEM out of the box, unfortunately no data will be shown. There are some manual configuration and upgrades to be done. In the rest of the post I’ll explain some hurdles you have to overcome to get this working.

By the way, it’s not unthinkable that LMS will accept the outcome of these reports as a valid source for counting the (in)compliancy on a relative short notice.


Oracle licenses and the cloud

By | March 15th, 2015|Categories: Database, licensing|Tags: , , , , , |

Suppose the number of Oracle licenses you acquired in the past, is in line with the use. That is, you’re compliant with all the licensing rules Oracle come up with. The  license form you use is the so called ‘Full use’ license, this is the most common license form. Everybody happy. But will this change when moving servers, databases or middleware  to the public cloud?

Well , ‘It depends…’ :

1. Is the chosen cloud provider an ‘authorized cloud’ by Oracle

2. Are you going to use your own licenses (BYOL = ‘Bring Your Own License’) or is this included in the cloud solution

3. Is the use of the software the same as it ever was

I’ll try to explain this in chapters below.


Oracle has changed the exhange rate of the Euro

By | March 2nd, 2015|Categories: licensing|Tags: , |

For years the number of 0.7893 meant something to those who are working on regular basis with licenses in Europe. This number is the ‘Current local Pricing Exchange rate’.

And Oracle is entitled to change this rate twice a year:



A short guide to networking in Virtual Box with Oracle Linux inside.

By | August 17th, 2014|Categories: Database|Tags: , , , , , , |

This post is intended to be a dummy guide, best practices, or whatever you call it…   about setting up a network while working with virtual boxes on a desk- or laptop. I was setting up a virtual box environment with several Virtual Boxes on my laptop, and as I’m not a network – specialist, I came across a few annoying things, challenges if you like.  And when I was googling around, it appeared to be I’m not the only one, so I felt the urge to share some experiences.

Already published this post on the amis-blog by the way, a long time ago. Decided to publish it also on my own blog.

What I want is the following environment and some elements smells like a subset of the real life:

1. Connect from my laptop to my virtual box through ssh and sqlplus, with fixed ip-address.

2. Simulate a private network, a network between the virtual boxes, also with fixed ip-addresses.

3. Occasionally connect to the internet from within the virtual boxes. To performs a ‘yum update’ and that kind of stuff.



Configuring a private DNS server on Openfiler for use with Oracle RAC 12C on Virtual Boxes

By | June 7th, 2014|Categories: Database, RAC|Tags: , , |


This post has already been published in the past on the AMIS-blog.

To build an Oracle 12C RAC database – on Virtual Boxes – there’s at least shared storage needed for ASM, and a DNS-server for the SCAN-addresses. Several methods can be used for this, but  for the storage in my private project I chose Openfiler, an open source management storage tool, on a separate Virtual Box. It’s like a SAN in real life (the complete system will be three Virtual Boxes: two RAC-nodes and 1 storage Virtual Box). Version Openfiler: 2.99.

O.k. storage is clear, but what about DNS? The quickest and dirtiest way to accomplish this is to use Dnsmasq on every RAC-node. A nice blogpost about this subject is here to be found.

But what I want is a separate DNS-server, just as in real life. The perfect candidate is to use the separate Openfiler Virtual Box
