Error in Manager Service Communication
IaaS servers cloned from a template where DTC was already installed contain duplicate identifiers for
DTC, which prevents communication among the nodes.
Problem
The IaaS Manager Service fails and posts the following error to the manager service log.
Communication with the underlying transaction manager has failed. --->
System.Runtime.InteropServices.COMException: The MSDTC transaction manager was
unable to pull the transaction from the source transaction manager due to
communication problems. Possible causes are: a firewall is present and it
doesn't have an exception for the MSDTC process, the two machines cannot
find each other by their NetBIOS names, or the support for network transactions
is not enabled for one of the two transaction managers.
Cause
When you clone an IaaS server that already has DTC installed, the clone contains the same unique
identifier for DTC as the parent. Communication between the two machines fails.
Solution
1 On the clone, open a command prompt as Administrator.
2 Run the following command.
msdtc -uninstall
3 Restart the clone.
4 Open another command prompt, and run the following command.
msdtc -install manager-service-host-FQDN
Email Customization Behavior Has Changed
In vRealize Automation 6.0 or later, only notifications generated by the IaaS component can be
customized by using the email template functionality from earlier versions.
