Operating hints

Connection availability
On each of the four lines to TCH, the TCH connector periodically sends echo request messages in case no other operational data traffic is caused by the application.
Sign-on and sign-off
The participant should be signed on whenever possible. Only when significant technical outages at the participant site prevent FTM for Immediate Payments to process inbound payments signing off from RTPS should be considered. When a SignOn or SignOff has been received and processed by TCH all participants are informed with a system notification messages (EvtCd 982) about the change participants reachability.
Connector quiescing
Immediate payment systems need to be available 24 hours a day, 7 days a week. To accomplish this availability and to allow for scheduled maintenance on one participant site, individual connectors can be quiesced. In quiesce mode, this connector does not send any new traffic to the RTPS but still completes all in-flight transactions. After about 2 minutes in quiesce mode the connector can be shut down, and maintenance can start. The other participant site now handles all traffic.
Controlling monitoring for data capture
By default, all monitoring functions are turned off in IBM® App Connect Enterprise. To enable flow monitoring, use the mqsichangeflowmonitoring command.
Controlling tracing
Tracing can be turned on and off by using IBM Integration Explorer, the IBM App Connect Enterprise Console, or the mqsichangetrace command.
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.
