EM Ops Center Embedded in Exalogic Virtual Configurations Cannot Launch Virtual Console To Virtual Servers Created Directly by OVMM (Doc ID 1517337.1)

Last updated on OCTOBER 12, 2018

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 2.0.1.0.0 to 2.0.6.1.1
Linux x86-64

Symptoms

You have an installation of Exalogic Elastic Cloud Software 2.0.1 deployed in a virtual configuration using version 2.0.1.1.0 of the Exalogic Control Stack. Under the Enterprise Manager Ops Center Control (EMOC), under the "Assets" accordion panel there are two "views" (selectable via a drop down menu) that allows you to view servers present in the system and any virtual machines running on those servers. The two views are selectable from a drop down menu offering the following choices:

  1. Exalogic Systems
  2. Server Pools

Under these views, if you locate and right click on a virtual server entry a "Virtual Console" menu option is available (and selectable) that allows you to initiate a VNC session that is started automatically by the OpsCenter console.

In the case of a virtual servers located anywhere under the "Assets" accordion panel that was created by a "Create vServer" job initiated by EMOC, when you right click and select "Virtual Console" option, the following sequence of events occurs and the VNC session is successfully established:

  1. the Blue "O" icon at the top right of the main browser window spins for 1-2 seconds (sometimes linger)
  2. in the Jobs area, a new job of type "Create ssh tunnel" is created
  3. after a few seconds a dialog box from the browser appears, requesting confirmation of the action to perform for a file "ovm_rasproxy-ws.jnlp" being returned to the browser
  4. it can be selected to open the file using the Java Web Start action and shortly after this a console window appears.


If the Virtual Server entry was created not by an EMOC "Create vServer" job but by creating a virtual server directly under Oracle VM Manager (using a create virtual machine or clone from template option), then the following occurs:

  1. the Blue "O" icon at the top right of the main browser window spins for 1-2 seconds
  2. no virtual Server new job of type "Create ssh tunnel" is created
  3. the dialog box from the browser appears, requesting confirmation of the action to perform for a file "ovm_rasproxy-ws.jnlp" never appears
  4. no VNC session is established

When you encounter this issue, the cacao log for the EnterpriseController (EC1) component of the Exalogic Control Stack (located at: /var/opt/sun/cacao2/instances/oem-ec/logs/cacao.0 in the filesystem of the virtual server running EC1) contains the following log sequence related to the failure:

However, whilst the above results in an error the virtual console of the same virtual server is working and can be accessed successfully from a similar menu option available from within the browser interface for the Oracle VM Manager control.
