This subsection describes the configuration where the executing node and the standby node of Application Server are in 1-to-1 ratio and the transaction service is used.
This is a system configuration that uses a transaction service when using a global transaction. A shared disk device is required in such cases.
This subsection also describes the configuration where node switching is performed by Application Server. For details about the configuration where node switching is performed by Management Server, see 3.11.3 Configuration in which executing node and standby node of Management Server are in 1-to-1 ratio.
The following figure shows an example of a configuration where a transaction service is used:
Figure 3-55 Example of system configuration where executing node and standby node of Application Server are in 1-to-1 ratio and cluster software is used (when transaction service is used)
Note: For other legend items, see 3.2 Description of the system configuration.
The software and processes required on respective machines are the same as when the transaction service is not used.
