The Application Tier<br />

Failover the Application Tier<br />

After setting up the primary application-tier server, you can add a warm standby computer to<br />

allow a warm failover of the application tier.<br />

Standby Hardware and Software<br />

The standby server does not need to be identical to the primary server, but it must match the<br />

hardware requirements for the application tier. You install the TFS application-tier software onto<br />

the warm standby server.<br />

You must ensure that both servers have the same configuration, including the same user<br />

accounts, permission changes, and software updates. Any updates on the primary computer must<br />

also be applied to the warm standby server.<br />

To minimize any problems <strong>with</strong> the failover, you must configure the network adapters to use the<br />

same host name from both the primary and standby computers. There are many ways to do this.<br />

Failing over the Application Tier <strong>Server</strong><br />

You fail over the application tier server manually. When the primary server fails, you have to<br />

complete the steps to manually activate the warm standby server. You can run the<br />

TFSAdminUtil utility passing the ActivateAT command, on the standby server, to help fail<br />

over the primary server.<br />

To warm fail over the server:<br />

1. Take the original server offline when the standby application-tier server is activated.<br />

2. On the standby server<br />

a. Log as administrator.<br />

b. Run TFSAdminUtil passing ActivateAT<br />

c. Start the Web services on the standby server.<br />

This command will<br />

• Register the warm standby server name in the TFS integration database.<br />

• Connect the warm standby application-tier server to the active data-tier server.<br />

• Verify that the correct application-tier server is connected to the correct data-tier<br />

server.<br />

Summary<br />

The TFS architecture has three tiers: an application-tier, a data-tier, and a client-tier. When you<br />

install the server, you can choose to install the application and data tiers on the same server or on<br />

separate servers. Your choice of TFS deployment depends primarily on the number of users you
