4.0.0 HP PolyServe Software for Microsoft SQL Server Administration Guide (T5392-96056, March 2010)

Virtual IP: Specify the IP address that will be associated with this Virtual MSDTC.
Virtual MSDTC Name: Enter a name for this Virtual MSDTC; the name must be a valid NetBIOS name
and can include up to 15 characters.
Application name: An “application” provides a tag to group Virtual MSDTCs and related virtual
MSDTC services on the Applications tab. All of the resources associated with the application can then
be treated as a unit on the Applications tab. You can specify a new application name, select an
existing application name, or leave this field blank. However, if you do not assign a name, Matrix
Server will use the IP address for the Virtual MSDTC as the application name.
Policy: The policy determines the failback action that the Virtual MSDTC will take following a failover
to a backup node.
• AUTOFAILBACK. This policy, the default, is intended to return the Virtual MSDTC to its original
configuration, or as close to it as possible. After the Virtual MSDTC fails over to a backup node,
the ClusterPulse process watches the health of the nodes higher in the list of servers for that Virtual
MSDTC. When the health of one of these nodes is equal to or greater than the backup node where
the Virtual MSDTC currently resides, the Virtual MSDTC will automatically attempt to fail back to
that node.
• NOFAILBACK. This policy is intended to minimize failovers and is the default. The Virtual MSDTC
remains active on the backup node until a “healthier” node becomes available, at which point
the Virtual MSDTC fails over to that node. (On a “healthier” node, more of the services associated
with the Virtual MSDTC will be up than on the node currently hosting the Virtual MSDTC. “Up”
includes the probe statuses UP and Standby.)
Network Interfaces Available/Members: The Available column lists the network interfaces that meet
the conditions required for the Virtual MSDTC. Move the interfaces on which the Virtual MSDTC should
be configured from the Available column to the Members column. The first interface that you select is
the primary interface. The other interfaces that you select are backups. You can use the up and down
arrows to reorder the interfaces on the Members column.
When you click OK, a progress report will display the tasks required to create the Virtual MSDTC.
Click Run to start the operation.
