  • 1 Ratings


Migration from vRealize Automation 6.2.x to 7.x fails, you see these symptoms:
  • Unable to synchronizing the IaaS reservation entities from the IaaS database to the CAFE database.
  • In the IaaS migration log located at <drive>:\Program Files (x86)\VMware\vCAC\InstallLogs-<timestamp>\migrate.log file, you see entries similar to:

    Synchronizing reservations failed. Error: [DynamicOps.Common.Client.HtmlResponseException:  (500)

    Synchronize reservations and reservation policies: Failed

Note: The preceding log excerpts are only examples. Date, time, and environmental variables may vary depending on your environment.


This error occurs because of a time out, which is configured on the vRealize Automation CAFE appliance that is executing the migration, being hit due to a large amount of reservation data being synchronized from the IaaS repository to the CAFE repository when running the following command on the vRealize Automation Model Manager Data node during the migration process:

drive-letter:\Program Files (x86)\VMware\vCAC\Server\Model Manager Data\Cafe\Vcac-Config.exe" SynchronizeDatabases -dst Reservation,ReservationPolicy -v




To resolve the issue, extend the timeout on the vRealize Automation 7.x appliance.

To extend the timeout on the vRealize Automation 7.x appliance:

  1. Log in to the master vRealize Automation 7.x appliance using root credentials.
  2. Open the /etc/vcac/setenv-user file using a text editor.
  3. Add the line to the file:

    VCAC_OPTS="$VCAC_OPTS -Dclient.system.socket.timeout=300000"

  4. Save and close the setenv-user file.
  5. Restart the vcac-server service by running the command:

    service vcac-server restart

Note: The timeout is set to 300000 which equates to 5 minutes. You can extend this timeout if required but if you are using a load balancer, you must ensure that any load balancer's timeout should not forcibly close the connection as some load balancers close connections after 5 minutes. If you are not sure whether your load balancer has a connection time out configured, you can bypass the load balancer for the duration of the migration by pointing your vRealize Automation Load Balancer FQDN DNS record to the IP address of the master vRealize Automation node that you executed the migration on. After migration completes, you can revert and repoint your DNS records back to the IP address of your load balancer service.
