A couple of days ago I did a new install of the Oracle Database Software (on a Virtual Machine) and it kept failing. I got some oracle.cluster.verification.VerificationException error, but I could not get more information from the logs. Usually it’s a bit more detailed after the colon, but this time it just said: [hostname]: [hostname]. Continue reading
You can update your Oracle VM Servers (3.x) with the Oracle Public Yum Server. In the Oracle VM Manager console go to the ‘Tools and Resources’ tab and click ‘Server Update Management (YUM)’.
For the ‘YUM Base URL:’, use:
When enabling the GPG key, use:
(Oracle VM 3.x is based on OEL5) Continue reading
In Oracle Linux 6, it looks like the ‘oracle-validated’ package is missing, but Oracle actually renamed it to ‘oracle-rdbms-server-11gR2-preinstall.x86_64‘.
To quickly use the public yum repository of Oracle and install ‘oracle-rdbms-server-11gR2-preinstall.x86_64’:
yum clean all
yum install oracle-rdbms-server-11gR2-preinstall.x86_64
You will get the ‘latest’ build enabled.
If you don’t want this, vi /etc/yum.repos.d/public-yum-ol6.repo .
Today I ran into an add-on for FireFox which can create a wget command from a download file dialog box. First thing that came in mind was; Will this work for Metalink / My Oracle Support? Yes is does!
The add-on is called ‘cliget’ and can be downloaded here: cliget add-on for FireFox. Continue reading
[Commands used were against VirtualBox version 4…]
Sometimes you don’t want to use a lot of disk space on your VirtualBox for install software or any ‘temporary’ need of space.
Adding shared folders from your host to your VirtualBox guest is a good option to use. If you have a Windows guest and a GUI based Host, it it’s very easy; click, click, done.
But if you are using a command line based guest and/or host, it a bit more complex. Use this post as a guideline, Linux knowledge is assumed… Continue reading
The Easy Connect Naming Method allows you to connect to a database service without having to configure Net Service Names.
The most found example on internet is the one with typing the password at the command prompt when starting sqlplus:
$> sqlplus system/manager@db_machine:1521/db_servicename
However, this means that the password will be stored in you history of commands (linux). This is not really secure… but sqlplus does not accept it when no password is supplied when using easy connect.
If you want to login with easy connect without typing the password on the command line, you have two options: Continue reading
I was preparing some fresh installed OEL5.5 machines for database software installation, but after running ‘yum install oracle-validated‘, the OUI did not pass the prerequisites on two packages. It seems it did not install unixODBC-devel x86_64 and libaio-devel x86_64.
Their Linux may be unbreakable, but their ‘oracle-validated’ package on the public yum server seemed to be broken. Continue reading
Many people will use the WebLogic’s NodeManager to use the start script for starting Managed Servers:
The NodeManager will start the Managed Server using the script and monitor the Managed Server when it fails.
One of the mistakes people can make is creating their own start script and start the Managed Server using ‘nohup &’ within this script: Metalink [ID 984122.1] and [ID 861098.1]. The script will finish and the server keeps running, but the NodeManager thinks the Managed Server has failed… Continue reading
Oracle has released it’s first patch set for Oracle Database 11g Release 2 (188.8.131.52).

The Oracle Database version compatibility matrix and version support status matrix are almost mandatory when installing or upgrading clients or servers.
For information about patches, go here: Oracle database patches for Linux and Windows (on Metalink).
For announcements of security fixes, go to Critical Patch Updates, Security Alerts and Third Party Bulletin.
Oracle Database client / server version compatibility matrix
Oracle calls this Client / Server Interoperability Support, Note ID 207303.1
Oracle Database version release support status matrix
Oracle calls this the Database Releases Support Status Summary, Note ID 161818.1
You will be redirected to Oracle Support and you must be registered to gain access to the pages. I did not include the matrices, because these change over time.
