A cable - a kingdom for a cable. Can you already see something?

Ok - when you do things the first time you make mistakes.

This was my first server I've ever build from scratch. I fiddled around with some equipment before, but buying a number of components and installing them was new for me.

Now the motherboard I have does have no video card as the folks who typically buy these extreme motherboards do bring their own video cards with them to render the monsters they are about to slay.
With me things were not so bright. Although I also bought a nice 24' screen I was still seeing nothing - basically because there was nothing to plug it in to the server.
Well - another trip to the store to buy a simple video card.

I did however initially bought a wireless card for the machine as I intend to place the machine in my study room. Historically this is where my DSL connection ended, so there was always a router with a cable present.

To my surprise I could not install the Oracle VM Server without a network. Obviously this makes sense when you are using this product in a data center which does not use WiFi a lot but all shades and colors of cable.

I investigated the issue and found that the machine was perfectly aware of its network sockets (two of them) and the WiFi card was detected as well. The issue at hand was the fact that the Oracle VM Server kernel was not equipped with the modules to support the ath9k which is the Linux wireless support for these kinds of cards.

Briefly I thought about baking my new Oracle VM kernel. I have done so in the past, so I knew what it would take to do so. I did some checks and found out that I would need to install a gazillion pieces of software to be able to build a new kernel.

I quickly abandoned the idea and now settled for the idea that I will have Ubuntu system running on the Oracle VM and use this as a stepping stone to connect to the WiFi.

Still not there. See the next post.

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.

Add a user to the JavaSSO

In AS 10.1.3.x Oracle came up with the JavaSSO. Seems to be (from a high level perspective) a poor man's version of the SSO from the AS 10.1.2.x. Having said this it strikes me how little documentation is available for this feature. But we're explorers, aren't we? JavaSSO is based on a file based security provider. The two main files are: - jazn.xml - system-jazn-data.xml Both exist in the $OH/j2ee/ directory. This means that if you have more than one OC4J instance you need to edit both. The most basic task is to add a user. You can - of course try to do this by editing the xml files, but luckily Oracle provides the jazn.jar tool. Make sure that you use the correct java executable and start it: java -jar jazn.jar -adduser jazn.com andreas welcome1 You will be asked for the AbstractLoginModule username (oc4jadmin) and its password. Now we have a user but usually this has to be added to a role before it can do something useful: java -jar jazn.jar -grantrole users jazn.com an...
