I am a new learner about the Jboss data virtualization.

when I tried to install the  Jboss data virtualization, I want to do the install after a uninstall .

By searching solutions from the Internet ,I just do the uninstall with delete the relative directory about  Jboss data virtualization——DV-6.1.0.

However , the problem comes to me when I do a new install of Jboss data virtualization.

In the last step ,some red errors appears following:

Script /home/redhat/DV-6.1.0/jboss-eap-6.3/cli-scripts/disable-welcome-root.cli failed to run.

JBoss CLI command failed: /subsystem=web/virtual-server=default-host:write-attribute(name=enable-welcome-root,value=false)

{

    "outcome" => "failed",

    "failure-description" => "No ModelControllerClient was available to execute the request.",

    "command" => "/subsystem=web/virtual-server=default-host:write-attribute(name=enable-welcome-root,value=false)"

}

……
