Performance and scaling

On each site for the participant FI IT environment, run two TCH connector flows in dedicated IBM® App Connect Enterprise integration servers.

One connector communicates with TCH site 1, while the other connector communicates with TCH site 2. On the secondary site, all four connections that are provided by TCH in an active-active environment are in use by default.

The connector component is designed to run in a multithreaded, parallel mode and can be easily configured to run in multiple instances for supporting the required throughput. Even if one IT environment site fails, the remaining site is configured and tested to take all messages from the failed site so that all payment transactions are still fully processed.
