My endeavour with Oracle VM

So - I bought a decently sized system to have my own private cloud on it. The main motivation was the fact that currently it has become pretty difficult to run some Oracle software on your laptop.

Although a number of people do this you quickly realize that they just have a simple database installation on it or a plain WebLogic Server.

While this is satisfactory for a number of purposes it doesn't come near the things that I encounter in my day to day life. My customers typically have HA or even MAA environments, using RAC and some of the newest Fusion Middleware components.

When you simply want to re-enact an environment of that size your laptop will not be sufficient.

So - this journey is about the setup and "cloudy" ideas I have.

So what I have now is a system that offers me a good CPU, 64 GB of memory (probably the most expensive part nowadays) and 3 TB disk plus 512 SSD. All in all it cost me around 1800 Euro's. And as it was bought by my company the Dutch minister of finance is (hopefully) happily supporting my with this.

Let's see where this ends up.

Different silent install files WLS 10.3.2 and 10.3.3

Today I tried to cut some corners and use a silent.xml file for WLS 10.3.3 for a silent installation of 10.3.2. To my amazement on a clean machine I received the following error: oracle@xxx001:/opt/oracle$ java -Djava.io.tmpdir=/opt/oracle/tmp -jar /nfsstage/wls1032_generic.jar -mode=silent -silent_xml=./silent/wls_silent.xml -log=/tmp/wls.log Extracting 0%....................................................................................................100% The local BEA product registry is corrupted. Please select another Middleware Home or contact Oracle Support I checked the wls_silent.xml file and found that it includes Coherence, which was not bundled with the 10.3.2 version. So I modified the 10.3.3 silent_xml file from value="WebLogic Server/Core Application Server|WebLogic Server/Administration Console|WebLogic Server/Configuration Wizard and Upgrade Framework|WebLogic Server/Web 2.0 HTTP Pub-Sub Server|WebLogic Server/WebLogic JDBC Drivers|WebLogic Server/Third ...

Unpacking Oracle cpio for AIX

When extracting a cpio file with Oracle software from OTN on AIX you might encounter the following problem: oracle@mymachine-app:/install/oracle/MRCA>cpio -idmv cpio: 0511-903 Out of phase! cpio attempting to continue... cpio: 0511-904 skipping 642010 bytes to get back in phase! One or more files lost and the previous file is possibly corrupt! Segmentation fault The solution is to use the option -idcmv oracle@mymachine-app:/install/oracle/MRCA>cpio -idcmv c Reads and writes header information in ASCII character form. If a cpio archive was created using the c flag, it must be extracted with c flag.

Oracle VirtualBox - first (short) impressions

I am using Oracle VirtualBox now since a couple of weeks in order to establish if it can replace my VMWare Server. I want to put down a couple of quick impressions - which will hopefully be followed up by some more insight. Speed: It seems that Oracle VirtualBox is faster than the VMWare Server. Creating an image as well as starting it up and shutting it down are pretty fast. However if your machine is pushing the limits on memory the shutdown process of an image can easily take 5 minutes. FAT/NTFS: I have not yet found the possibility to create a disk file in chunks of 2GB. VMWare offered this OOTB. Now when I move my image from my Windows7 NTFS filesystem to the FAT external disk it complains about a 20GB file. More research is needed here. Distributing images: I copied the images and gave them to some colleagues during several trainings. My experience is that the different laptops we use are not handled well by VirtualBox. E.g. I had to remove a network from the vbox-file in order t...
