Rules and Guidelines for Real-time Sessions

Rules and Guidelines for Real-time Sessions

Use the following rules and guidelines when you run real-time sessions:
  • The session fails if a mapping contains a Transaction Control transformation.
  • The session fails if a mapping contains any transformation with Generate Transactions enabled.
  • The session fails if a mapping contains any transformation with the transformation scope set to all input.
  • The session fails if a mapping contains any transformation that has row transformation scope and receives input from multiple transaction control points.
  • The session fails if the load scope for the target is set to all input.
  • The Integration Service ignores flush latency when you run a session in debug mode.
  • If the mapping contains a relational target, configure the load type for the target to normal.
  • If the mapping contains an XML target definition, select Append to Document for the On Commit option in the target definition.
  • The Integration Service is resilient to connection failures to WebSphere MQ and JMS. It is not resilient to any other messaging system.
  • When a real-time session contains a request and a response, such as in a web service, the session log contains start and end times for the request and response. When a real-time session contains a publish/subscribe or point-to-point architecture, the session log contains statistics that describe when the Integration Service commits rows to the target.
