Fault Tolerance implementation in tibco EMS

You can arrange TIBCO Enterprise Message Service servers for fault-tolerant operation by configuring a pair of servers—one primary and one backup.

The primary server accepts client connections, and interacts with clients to deliver messages.
 If the primary server fails, the backup server resumes operation in its place.

Configuring Primary and Backup Servers:

The Server name , Configuration files and data store should same for both the  servers.

Configuring Primary Server: Here ft_active represents the back up server listening url.

 Server = EMS-SERVER-MSS
Listen = tcp://7222
ft_active = tcp://7666
ft_heartbeat            = 3
 ft_activation           = 600
 ft_reconnect_timeout    = 90

Configuring Backup Server: Here ft_active represents the Primary server listening url.

Server = EMS-SERVER-MSS
Listen = tcp://7666
ft_active = tcp://7222
ft_heartbeat            = 3
 ft_activation           = 600
 ft_reconnect_timeout    = 10000

Start Both the servers then you will find the following statements in server consoles.

In primary server console window:

Backup server 'EMS-SERVER-MSS@D380D075RG' has connected. 

In Backup Server console Window:

 Server is in standby mode for 'tcp://7222'.

for cross verification stop the primary server then the backup server will be active means the role is reversed.
