PI AEX & AAE - Using distributed adapters

Former Member

Hi Experts,

We are using PI - AEX 7.31 in our landscape & recently we have installed a Decental AAE to use do the file pooling for window unc.

We created an iflow and tried to include one communication channel configured to run on the central adapter engine and one configured to run on the Decental adapter engine (AAE).

Only those communications channels configured for the adapter engine that the iflow is configured on are available for selection – i.e. you can’t see any other communication channels in the list of available channels.

So We changed the iflow to run on the Decental AAE adapter engine. This allowed us to use the communication channels configured for the AAE adapter engine. As our iflow didn’t involve any mapping, just copying a file, We could run the configuration on the Decental AAE adapter and the file was copied successfully. This isn’t practical for most interfaces as we need to do mapping on the central adapter on AEX.

Then We tried to change the iflow back to running on the central adapter AEX, while leaving the channels running on the Dcentral AAE adapter. When We activated the iflow We got the error :

ERROR of type OBJECT_NOT_FOUND for FILE_to_File_Test Details:

Referenced channel RIO_EXTENDATA | RIO_EXTENDATA | FileReceiverTestDist

adapter engine does not match adapter engine of integration flow_

Can you please advise & suggest how we can we use both adaptors in single iflow.

Warm Regards,

Ajay Sehgal

Hi Ajay,

Unfortunately, currently this is not feasible: runtimes of Adapter Engines (central, non-central) are isolated from each other and it is not currently possible to have the single Java-only scenario that is using communication channels running on different Adapter Engines. The current limitation is that all communication channels for such scenarios should be running in the bounds of the same Adapter Engine.

Hi Vadim,

Thanks for your response. So do you mean to say if we dont have a PI (dual stack) we cant use the distributed adaptors (central & decentral) for creating single iflow.

Is there any SAP documentation which mentions about this limitation or what all can be achieved with AEX & Decentral AAE.

I have been looking documentation for last couple of days but there is very limited documentation available for AEX with decentral AAE like test cases, conifguration & so forth.

Warm Regards,

Hello Ajay,

You can check, for example, the follow SAP Help material that is describing configuration of communication channels when developing iFlows: SAP Library - Process Integration Tools (Eclipse-Based) . In the section 2 ("Configure the channel properties"), you can see the following statement that gives a hint on the discussed limitation: "The adapter engine should be the same as the adapter engine you have selected for the integration flow in the General tab in the Properties view of integration flow.".
