Hi,

Can any body tell me whether the persistence layer for Adapter Engine and Integration Engine(IS) same?

Thx in advance

Hi,

They are not the same. Integration engine is using RFC queues and adapter engine is using java message queues. So one is on abap stack and the other one is on java stack.

Hi,

SAP XI always persists asynchronous messages in the runtime persistence layer, whereas synchronous messages can only be persisted if errors occurred or for logging purposes in the Integration Engine. Only successfully processed asynchronous messages in the persistence layer can be archived or deleted. Messages with errors are never automatically deleted, but only manually by administrators

The Integration Server, the Adapter Engines, and the PCK have a runtime persistence layer for short-term storage of executed messages and an archiving component for long-term storage. The Integration Server uses the ABAP part of the SAP Web Application Server (AS), and the Adapter Engine and the PCK use the J2EE part of the SAP Web AS.

XI have persistance at each layer of message transport using Async mode of transport.
