Title:  Unable to run a CA XOsoft High Availability (HA) scenario due to license errors.


When starting a High Availability (HA) scenario you may receive the following error in the XOsoft Console GUI:

EM00577 Error Test 25.08.2008 11:53:49 Unable to perform action. No registered license for this operation. You need to purchase at least 1 additional license(s) of Application Server HA for Windows Enterprise edition.


Check you have sufficient CA XOsoft licenses. To check CA XOsoft licenses please perform the following steps on the CA XOsoft Control Service machine:

  1. Open the 'CA XOsoft Overview' page and login with appropriate credentials.
  2. Under the 'Quick Start' banner select Scenario Management.
  3. Click on Help | Register; now you should see the XOsoft license details.

Below is an example:

License info:
License expires on: Never
Maintenance till: June 21, 2009
License is incremental
Number of Assured Recovery nodes: 0
Number of CDP Repository nodes: 0
Product list:
- Application Server, Windows Enterprise edition, 1 instances HA


  • In the 'Product List' section of the license, the number refers to the number of hosts that type of license supports.

    • '1 instance HA' indicates one server.
  • Ultimately you will need (1) license per host defined in the CA XOsoft Manager.
  • HA scenarios require 'HA' licenses.
  • DR scenarios require 'Replication' licenses'.
  • The Number of Assured Recovery nodes needs to match the number of hosts defined in a scenario in which Replica Integrity Testing for Assured Recovery enabled on the scenario and defined in the CA XOsoft Manager.

To address these licensing issues, please contact your local CA representative/reseller.

Alternatively visit select the country and then click on 'Contact Us' at the bottom of the web page.
