Pentaho Business Intelligence Suite so far is the best freely available open-source Business Intelligence Tool. It integrates Kettle (data integration), Mondrian (OLAP server), Weka (data mining), jfreereport and a Tomcat Web server to publish business analytics.
Extract it (e.g., ”/opt”)
Grant execution rights to the BI folder and substructure
chmod u+x bi-folder -R
Make sure your JAVA_HOME variable is set properly and add it to your path by
export JAVA_HOME=/path/to/my/java/lib (e.g., /usr/lib/jvm/java-6-sun)
Alternatively you can set your variables in .bashrc.
Add BI paths (admin console & BI server) to your system PATH to be executable from everywhere
Now you can start BI by executing
start-pac.sh (only works if started within the admin-console folder) for the admin console and start-pentaho.sh for the BI server. Database Connection
Copy your data base JDBC driver into the BI folders, e.g.:
Optional you can migrate the sample repository into your DB. See the README.txt in biserver-ce/data/ in your BI folder.
After starting the Administrator Console you can easily add a new data connection
Insert connection name
Select appropriate driver class
Insert DB user name & password
URL according to following syntax:
# e.g.: jdbc:postgresql://localhost:5432/mydb
Since VM ESXi 3.5 is officially not capable of hosting virtual Windows 7 machines, its not surprising that there are some problems if you try it anyway.
We found a way – thanks to several posts of the
VMware Community – which we want to preserve here:
Set up a new virtual machine using the Windows Vista (32 or 64 bit) template (some believe only the XP template works).
After complete installation,
Windows 7 hangs up while booting
Power down the VM and
turn off the network adapter
Boot again and do an advanced install of the VMware Tools excluding SVGA drivers as well as drivers for performance measurement.
Turn off the VM.
Change network adapter option in the .VMX file from ‘ethernet0.virtualDev = “e1000”’ to ‘ethernet0.virtualDev = “
Enable the network adapter at ‘power on’.
Now it should boot without problems!
Migrating an existing or even fresh VM with Windows 7 onto a VM ESXi 3.5 did not work at all. VM ESXi tags the machine as ‘invalid’.
Detailed Information about VM network adapters can be found in the references.
We have not tested it for the 64bit version, though, the problem should be the same.
Another solution, of course, is upgrading your VM ESX to ESXi 5.
Export the vm in VirtualBox, thereby you create a
.VMDK file, which basically is a virtual harddisk. Although, VMplayer works with .VDMK files you have to configure a .VMX file in order to run it.
If you own a VM Workstation edition you just create a new virtual machine and select your .VDMK when you are ask to create a new or select an existing virtual machine disk.
In case you set the option “dynamically resizeable” in VirtualBox you might want to try these
instructions. Here are the main steps to undertake this mission:
Convert your .VDI to a .raw image by the vboxmanage shell command:
vboxmanage internalcommands converttoraw .VirtualBox/HardDisks/myvm.vdi vmware/myvm.raw
Convert the .raw image to a .VMDK file:
qemu-img convert -O vmdk myvm.raw myvm.vmdk
Create a VM with VMplayer and exchange the .VMDK with your own, either by renaming or changing the config in the .vmx file.
Make sure your user has read rights to the .VMDK or is owner.
Problems running VirtualBox and VM software
Running VirtualBox and VMplayer or the like in parallel leads to problems, e.g.
VirtualBox can’t operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_VMX_IN_VMX_ROOT_MODE).
If you execute the VM software and then want to start a vm out of VirtualBox you will have to disable your
KVM like this: sudo rmmod kvm-intel # for intel processors
sudo rmmod kvm-amd # similar for amd
To enable the KVM module again just type
in your shell.
Since re-installing an
OS in general is not exactly an event you wanna spent your whole weekend on here are some practical hints to speed up the process. Preparation & Backup
Backup your home directory
Backup software in /opt
Backup essential files
Make and backup a list of installed applications
dpkg --get-selections > installed-software
Re-install your Ubuntu
Copy essential files
Copy software profiles from your home folder
dselect and start installing your applications sudo apt-get install dselect
In parallel you already can copy your data back on your machine, as dselect will take a while.
Copy software to /opt and add it to your menu
Transfer of keyrings
Biggest pain in the ass when I changed my
OS to Ubuntu were errors caused by mix up of SUN and Open Java Versions available. Set Environment Variable
To save some trouble set the $JAVA_HOME variable in .bashrc etc.
export $JAVA_HOME=/your/java/home/path (e.g., /usr/lib/jvm/java-6-sun)
Set Java Configuration
If you have to have two versions or as in my case Open Java is re-installing through means of magic, select the right version by
sudo update-alternatives --config java
So far so good…
