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 [https://docs.oracle.com/middleware/1221/biee/BIEMG/deploy_rpd.htm#BIEMG1465] of connecting to data sources: 1. Native Gateway [https://docs.oracle.com/middleware/1221/biee/BIEMG/deploy_rpd.htm#BIEMG1179] , such as OCI for Oracle. This

System Metrics Collectors

The need to monitor and control the system performances is not new. What is new is the trend of clever, lightweight, easy to setup, open source metric collectors in the market, along with timeseries databases to store these metrics, and user friendly front ends through which to display and analyse

New OTN Article - OBIEE Performance Analytics: Analysing the Impact of Suboptimal Design

I’m pleased to have recently had my first article published on the Oracle Technology Network (OTN) [http://www.oracle.com/technetwork/index.html]. You can read it in its full splendour and glory(!) over there [https://community.oracle.com/docs/DOC-993649], but I thought I’d give a bit

Using Linux Control Groups to Constrain Process Memory

Using Linux Control Groups to Constrain Process Memory

Linux Control Groups [http://docs.oracle.com/cd/E37670_01/E37355/html/ol_about_cgroups.html] (cgroups) are a nifty way to limit the amount of resource, such as CPU, memory, or IO throughput, that a process or group of processes may use. Frits Hoogland [https://fritshoogland.wordpress.com/2012/

OBIEE Monitoring and Diagnostics with InfluxDB and Grafana

In this article I’m going to look at collecting time-series metrics into the InfluxDB database and visualising them in snazzy Grafana dashboards. The datasets I’m going to use are OS metrics (CPU, Disk, etc) and the DMS metrics from OBIEE, both of which are collected using the support

Linux cluster sysadmin -- OS metric monitoring with colmux

In this mini-series of blog posts I'm taking a look at a few very useful tools that can make your life as the sysadmin of a cluster of Linux machines. This may be a Hadoop cluster, or just a plain simple set of 'normal' machines on

Linux cluster sysadmin -- Parallel command execution with PDSH

In this series of blog posts I'm taking a look at a few very useful tools that can make your life as the sysadmin of a cluster of Linux machines easier. This may be a Hadoop cluster, or just a plain simple set of 'normal' machines

Linux cluster sysadmin -- SSH keys

In this short series of blog posts I'm going to take a look at a few very useful tools that can make your life as the sysadmin of a cluster of Linux machines easier. This may be a Hadoop cluster, or just a plain simple set of '

SampleApp v406 - Automatic startup of OBIEE

Last week Oracle released v406 of SampleApp [http://www.oracle.com/technetwork/middleware/bi-foundation/obiee-samples-167534.html] . SampleApp is a one-stop-shop for a demonstration of pretty much any conceivable thing that OBIEE is capable of, and then some more on top of it. It is a VirtualBox [https://www.virtualbox.org/

Oracle BI Suite EE

Make Use of OBIEE's Command Line Tools with Reduced Exposure of Plain Text Passwords

Introduction We all love a good commandline utility. It gives us that warm feeling of control and puts hairs on our chests. Either that, or it means we can script the heck out of a system, automate many processes, and concentrate on more important matters [http://phoboslab.org/ztype/]. However,

Oracle BI Suite EE

Tips and Tricks for the OBIEE linux sysadmin

As well as industry-leading solution architecture, consultancy and training on Oracle BI, here at Rittman Mead we also provide expert services in implementation and support of such systems. In this blog I want to share some of the things I find useful when working with OBIEE on a Linux system.

Downloading OBIEE patches from Oracle with wget

Last week saw the release of OBI 11.1.1.6.2 BP1 [https://www.rittmanmead.com/blog/2012/07/obiee-11-1-1-6-2-bp1-new-features-oracle-bi-mobile-hd-and-patching-upgrade-considerations/] , and with it, some eight patches to download (seven OBIEE, plus one JDeveloper). A very useful option when downloading the patches, particularly if you are working on Linux servers

screen and OBIEE

With the recent delivery of the Rittman Mead Exalytics server [https://www.rittmanmead.com/blog/2012/05/rittman-mead-take-delivery-of-our-exalytics-server/], I have been fortunate enough to be spending time setting it up, most of it at a Linux terminal window. One of the tools I come back to, again and again, is

Configuring OBI 11g to use port 80

Introduction By default, OBI 11g will listen for connections on port 7001 or port 9704 depending on your installation type. There are several reasons you may want to change this, and one of them would be to make it use port 80, the default http port. If you use port

Running the OBIEE Administratiol tool on Unix using Wine

The other day I was playing with getting OWB11gR2, which at the time of this writing, has only been released under Linux and Solaris, to run under Windows [https://www.rittmanmead.com/blog/2009/12/10/owb11gr2-on-windows/]. In the pursuing comments Jon Mead threw down the gauntlet and asked if

OWB 11gR2 Workspace Creation Issues

First of all, I'd like to thank David Allan of the OWB Product Team for helping me solve the problem I discuss below... and also for identifying what he thinks to be the cause. A few days after Oracle Database 11gR2 was available, I went about building my

Managing multiple Presentation Services on the same Unix box

As I had mentioned, I wanted to write up a bit on how to go about setting up multiple Oracle BI presentation services, each configured to access a different repository file (RPD) running on the BI Server. The thing is that you can easily set up the BI server so

Installing OBIEE 10.1.3.2.1 on Ubuntu Part II

Ok, so I tried running the OBIEE installer again, this time choosing only BI Server option. When I read through the install.log I noticed that it was complaining about that the UnixChk.sh didn't exist. The reason for that was simple, I had renamed it when I

Installing OBIEE 10.1.3.2.1 on Ubuntu 7.04 … not so fast

Well, this was a productive 2 hour stint. I just managed to hack my way past the OBIEE installer to get ahead to the actual installation. After downloading the cpio (I chose the RedHat file, since I knew that I could at least install the Oracle Linux because I have
