4.3 Disable Network Proxy Authentication Popup

There is a specific RHEL 6 issue that causes users to receive a popup asking for the root password

after logging on.

To workaround this issue, as root, create the file

/etc/polkit-1/localauthority/30-site.d/20-no-show-proxy-dialog.pkla in a text editor and add

the following content:

[No Show Proxy Dialog]

Identity=unix-user:*

Action=org.freedesktop.packagekit.system-network-proxy-configure

ResultAny=no

ResultInactive=no

ResultActive=no

For more information on this issue, see https://access.redhat.com/solutions/195833#md25. The

correct workaround is described in the comments section.

4.4 Install Linux VDA Dependent Packages

4.4.1 Install OpenJDK

The Linux VDA has dependencies on OpenJDK 1.7.0. The runtime environment should have been

installed as part of the operating system installation; confirm this with:

sudo yum info java-1.7.0-openjdk

On RHEL 6.6, the pre-packaged OpenJDK is about 10 patch versions out-of-date. Update to the

latest version as required:

sudo yum -y update java-1.7.0-openjdk

This will install java under /usr/lib/jvm. Set the JAVA_HOME environment variable by adding

the following line to ~/.bashrc file:

export JAVA_HOME=/usr/lib/jvm/java

Open a new shell and verify the version of Java:

java -version

To avoid problems, do not install Oracle Java, IBM Java or multiple versions of OpenJDK.

4.4.2 Install PostgreSQL

The Linux VDA requires PostgreSQL 8.4 or later. On RHEL 6.6, the latest version is 8.4.20.

Install the following packages:

sudo yum -y install postgresql-server

sudo yum -y install postgresql

sudo yum -y install postgresql-devel

sudo yum -y install postgresql-jdbc

The following post-installation step is required to initialize the database and ensure service starts on

boot. This will create database files under /var/lib/pgsql/data.
