OBIEE12c – Upgrading to Version 12.2.1.1

INTRODUCTION

The new version of OBIEE 12c, 12.2.1.1 to be exact, is out, so let’s talk about it. It’s my intent that after reading this, you can expect some degree of comfort in regards to possibly doing this thing yourself (should you find yourself in just such a circumstance), but if not, feel free to drop us a line or give us a ring. It should be noted that Oracle documentation explicitly (more...)

Becky’s BI Apps Corner: OBIA 11.1.1.10.2 New Features Part 1 – Health Check & ETL Diagnostics

I have been working with BI Applications since OBIA switched to ODI in version 11.1.1.7.0. I have installed and worked with all of the 11.x versions using several different sources. This most recent version of OBIA may only be a Patch-Set release, but it has some new features that make it very compelling; ETL automatic error handling, Health Check, ETL Diagnostics, and built in Email notifications.

If you've been using (more...)

Becky’s BI Apps Corner: OBIA Back-to-Beginnings – Naming Conventions and Jargon

It's easy to talk about a technology using only jargon. It's much harder to talk about a technology without using jargon. I have seen many meetings between business and IT break down because of this communication barrier. I find it more discouraging when I see this communication breakdown happen between advanced IT staff and new IT staff. For those of us in any technological field, it's easy to forget how long it took to learn (more...)

How To Poke Around OBIEE on Linux with strace (Working with Unsupported ODBC Sources in OBIEE 12c)

OBIEE 12c (and 11g and 10g before it) supports three primary ways of connecting to data sources:

  1. Native Gateway, such as OCI for Oracle. This is always the preferred option as it gives the greatest support and performance.
  2. Data Direct ODBC Drivers, a set of which are bundled with OBIEE for enabling connectivity to sources such as SQL Server, MySQL, Hive, and Impala. The configuration of these is documented in the OBIEE manuals (more...)

Analysing Social Media Data for the Lightyear Foundation – Part 1

Outside of my job at Rittman Mead, I'm fortunate enough to be involved with a project called the Lightyear Foundation. We are a charitable organisation which aims to promote the techniques and philosophies of science, working with children and teachers in the UK and in Ghana. Particularly, we try to exemplify the fact that fundamental science principles can be demonstrated without the need for formal labs and expensive equipment. We believe that in increasing the (more...)

OBIEE 12.2.1.1.0 – New Feature Guide

OBIEE 12.2.1.1.0 - New Feature Guide

Oracle has recently released version 12.2.1.1.0 for OBIEE 12c, which has a variety of exciting new features for Data Visualization, BI Publisher, Dashboards in OBIEE, and ODBC connections. It can be performed as an in-place upgrade (performed by the Upgrade Assistant) or as a fresh install. The upgrade process is explained at length here. There is also an example Linux in-place upgrade from 12.2.1.0 to 12.2.1.1 which (more...)

Stream Analytics and Processing with Kafka and Oracle Stream Analytics

In my previous post I looked the latest release of Oracle Stream Analytics (OSA), and saw how it provided a graphical interface to "Fast Data". Users can analyse streaming data as it arrives based on conditions and rules. They can also transform the stream data, publishing it back out as a stream in its own right. In this article we'll see how OSA can be used with Kafka.

Kafka is one of the foremost streaming (more...)

An Introduction to Oracle Stream Analytics

An Introduction to Oracle Stream Analytics

Oracle Stream Analytics (OSA) is a graphical tool that provides “Business Insight into Fast Data”. In layman terms, that translates into an intuitive web-based interface for exploring, analysing, and manipulating streaming data sources in realtime. These sources can include REST, JMS queues, as well as Kafka. The inclusion of Kafka opens OSA up to integration with many new-build data pipelines that use this as a backbone technology.

Previously known as Oracle Stream Explorer, it is (more...)

Understanding CPU on AIX Power SMT Systems

This month I worked with a chicagoland company to improve performance for eBusiness Suite on AIX. I’ve worked with databases running on AIX a number of times over the years now. Nevertheless, I got thrown for a loop this week.

TLDR: In the end, it came down to a fundamental change in resource accounting that IBM introduced with the POWER7 processor in 2010. The bottom line is twofold:

  1. if SMT is enabled then the meaning (more...)

Username & password required at Weblogic domain startup

When installing a new WebLogic Domain for any a-specific Oracle (Fusion) Middleware application or any other implementation requiring a WebLogic domain like ORDS for instance, a new ‘home’ is created under [MW-home]/user_domains/. [MW-Home] translates, for instance, to /u01/oracle/product/Middleware.

ordsTo start your brand-new domain, or perhaps and rather, to automate the startup of your domain, you would use the supplied [MW-home]/user_domains/[DomainName]/startWebLogic.sh command-file.
This file will start the Weblogic domain (the Admin Server) and the deployed (more...)

DBA_FEATURE_USAGE_STATISTICS and SE2

This blog post is inspired on work I have been doing on Standard Edition databases and the returning confusion about what is and what is not part of Standard Edition.

DBA_FEATURE_USAGE_STATISTICS is a tool in determining license usage for the Oracle database. It is good to understand the implications of each entry, know what is happening in your database and thus be able to have a substantial conversation about the usage of your license, being (more...)

OOW 2015: my presentation

I don’t have an official OOW presentation in the conference this year. However, I am presenting a session at the Oak Table World 2015 event behind held concurrently with OOW 2015. My topic is “Exadata Database Machine Security” and I plan to review some of the newest updates to security for the Exadata Database Machine engineered system.

As the website indicates, the event is completely free and there is no pre-registration or enrollment required–just show (more...)

Patching Time

Just a quick note to point out that the October PSU was just released. The database has a few more vulnerabilities than usual (31), but they are mostly related to Java and the high CVSS score of 9 only applies to people running Oracle on windows. (On other operating systems, the highest score is 6.5.)

I did happen to glance at the announcement on the security blog, and I thought this short (more...)

Grid/CRS AddNode or runInstaller fails with NullPointerException

Posting this here mostly to archive it, so I can find it later if I ever see this problem again.

Today I was repeatedly getting this error while trying to add a node to a cluster:

OSP #3a: Build a Standard Cluster Platform

This is the fifth article in a series called Operationally Scalable Practices. The first article gives an introduction and the second article contains a general overview. In short, this series suggests a comprehensive and cogent blueprint to best position organizations and DBAs for growth.

We’ve looked in some depth at the process of defining a standard platform with an eye toward Oracle database use cases. Before moving on, it would be worthwhile to briefly touch (more...)

Chicago Oracle User Community Restart

Chicago is the third largest city in the United States. There are probably more professional Oracle users here than most other areas in the country – and yet for many years now there hasn’t been a cohesive user group.

But right now there’s an opportunity for change. If the professional community of Chicago Oracle users steps up to the plate.

Chicago Oracle User Group

First, the Chicago Oracle User Group has just elected a new (more...)

Command Line Attachment to Oracle Support Service Request

For those who haven’t looked at this in awhile: these days, it’s dirt simple to attach a file to your SR directly from the server command line.

curl –T /path/to/attachment.tgz 
     –u "your.oracle.support.login@domain.com" 
     "https://transport.oracle.com/upload/issue/0-0000000000/"

Or to use a proxy server,

curl –T /path/to/attachment.tgz
     –u "your.oracle.support.login@domain.com"
     "https://transport.oracle.com/upload/issue/0-0000000000/"
     -px proxyserver:port
     -U proxyuser

OEM CLI Commands for Bulk Property Changes

This will be a brief post, mostly so I can save this command somewhere besides the bash_history file on my OEM server. It may prove useful to a few others too… it has been absolutely essential for me on several occasions! (I was just using it again recently which reminded me to stick it in this blog post.) This is how you can make bulk property changes to a large group of targets in (more...)

November/December Highlights

In the Oracle technical universe, it seems that the end of the calendar year is always eventful. First there’s OpenWorld: obviously significant for official announcements and insight into Oracle’s strategy. It’s also the week when many top engineers around the world meet up in San Francisco to catch up over beers – justifying hotel and flight expenses by preparing technical presentations of their most interesting and recent problems or projects. UKOUG and DOAG happen shortly (more...)

Readable Code for Modify_Snapshot_Settings

It annoyed me slightly that when I googled modify_snapshot_settings just now and all of the examples used huge numbers for the retention with (at best) a brief comment saying what the number meant. Here is a better example with slightly more readable code. Hope a few people down the road (more...)
