Creating an MSDTC Server service group
Use the MSDTC Configuration Wizard (not the SQL Server Configuration Wizard) to configure a service group for the MSDTC Server. After configuring the service group, proceed to configuring the MSDTC client.
Note:
You can create only one MSDTC Server service group in a cluster.
To configure an MSDTC Server service group
- Start the MSDTC Configuration Wizard from the Apps menu on the Start screen.
- On the SQL Configuration Option panel, click MSDTC Server - Service Group Configuration, click Create and then click Next.
- Review and verify that you have met the prerequisites and then click Next.
- On the Service Group Configuration panel, specify the service group name and the system list, as follows:
Enter a name for MSDTC service group.
In the Available Cluster Systems box, select the systems on which to configure the service group and click the right-arrow to move the systems to the service group's system list.
To change a system's priority, in the Systems in Priority Order list, select the system and click the up and down arrows. Arrange the systems in priority order as failover targets for the group. The server that needs to come online first must be at the top of the list.
To enable the service group to automatically come online on one of the systems, select the Include selected systems in the service group's AutoStartList attribute checkbox.
For information about the AutoStartList attribute, see the Cluster Server Administrator's Guide.
Click Next.
If the configuration is in read-only mode, the wizard prompts you before changing it to read-write mode. The wizard starts validating your configuration. Various messages indicate the validation status.
- On the Virtual Server Configuration panel, specify the virtual server and network details and then click Next.
Complete the following steps:
Select IPv4 to configure an IPv4 address for the MSDTC virtual server.
In the Virtual IP Address field, type a unique virtual IPv4 address for the virtual server.
In the Subnet Mask field, type the subnet to which the virtual IPv4 address belongs.
Select IPv6 to configure an IPv6 address for the virtual server. The IPv6 option is disabled if the network does not support IPv6.
Select the network from the drop-down list. The wizard uses the network prefix and automatically generates an IPv6 address that is valid and unique on the network.
In the Virtual Server Name field enter a virtual server name for the node on which the DTC service is running. Ensure that the virtual server name you enter is unique in the cluster. This is the name that is used by MSDTC clients to connect to the MSDTC Server.
For each system in the cluster, select the public network adapter name. Click the Adapter Display Name field to view the adapters associated with a system. The wizard displays all TCP/IP enabled adapters on a system, including the private network adapters, if they are TCP/IP enabled. Make sure that you select the adapters to be assigned to the public network, and not those assigned to the private network.
If you require a computer object to be created in the Active Directory (AD), click Advanced Settings, check the Active Directory Update Required check box, specify the desired Organizational Unit in the domain and then click OK. The user account configured for VCS Helper service must have adequate privileges on the specified container to create and update computer accounts.
This sets the Lanman resource attributes ADUpdateRequired and ADCriticalForOnline to true. This allows the Lanman agent to update Active Directory with the virtual SQL Server name.
You can type the OU details in the format
CN=Computers,DC=domainname,DC=com.
To search for the OU, click the ellipsis button and specify the search criteria in the Windows Find Organizational Units dialog box.
By default, the Lanman resource adds the virtual server name to the default container "Computers."
- On the Specify Data Path panel, specify the volumes for the MSDTC log and the replication directory and then click Next.
Arctera recommends using different paths for these directories. If the directory does not exist, the wizard creates it.
- On the Service Group Summary panel, review the service group configuration.
Change the resource names if desired, as follows:
The Resources box lists the configured resources. Click on a resource to view its attributes and their configured values in the Attributes box.
The wizard assigns unique names to resources. Change names of the resources, if desired. To edit a resource name, select the resource name and either click it or press the F2 key. Press Enter after editing each resource name. To cancel editing a resource name, press the Esc key.
To enable all the VMDg resources in the service group for fast failover, select the Enable FastFailOver attribute for all the VMDg resources in the service group checkbox.
For information about the FastFailOver attribute, see the Cluster Server Administrator's Guide.
Click Next.
- Click Yes on the message that prompts you that the wizard will run commands to modify the service group configuration.
Various messages indicate the status of these commands.
- In the Configuration Complete panel, check Bring the service group online to bring the configured service group online and then click Finish to exit the wizard.
To bring the service group online later, uncheck the option.
