Decentral adapter engine & security

[Former Member]

Hi Guys,

We have a requrement wherein there are 10 business systems in the landscape to be connected to XI. would it be advisable to install 10 decentral adapter engines on all the 10 business systems to ensure the security of the message sent by the different systems to SAP XI? Can we install the decentral adapter engine on the business system itself? If not, what could be the best option to ensure the secured message delivery to XI system from all the different business systems. I have read the ppt https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/03fd85cc-0201-0010-8ca4-a32a119a...

where it says that the decentral adapter engine should be used when close proximity with the business system is needed. Does it mean that we have to install the decentral adapter engine on every business system from which we want to ensure secure message transfer?

Hi Ethan,

Have a look at this thread:

Thanks for yoru reply Carlos.

But it doesn't solve my query. My question is do we need to install the decentralised adapter engine in every business system in the topology to ensure the secure message transfer to the integration engine. if yes, how does it work & if no, what is the possible way to ensure the secure message transfer.

Hi Ethan,

Are your business systems inside your network/DMZ or outside?

We have the systems within network & outside the network as well.

So, I think your have the answer in the link above:

A decentral adapter engine is used when we need to connect to other applicaton systems through a firewall.
Xi does not provide any such security, so in order to ensure security and to allow minimal access to out sld and other objects we use an external adapter engine(a decentralised adapter engine). 
An example of using a decentralised AE would be when we connect the PCK

You could install a non-central adapter enfine/PCK in those business systems outside your network.

In your inside business systems is not necessary.

Hi Carlos,

Thanks again for your patient replies. Now, I have some more question.

1. Whether installing decentralised adapter engine for the systems "within the network" help in any way to ensure the message security? IF yes, How? If no, how the message security can be ensured in such scenarios?

2. Whether installing decentralised adapter engine for the systems "Outside the Network"help in any way to ensure the message security? If yes, How? If no, how the message security can be ensured in such scenarios?

Hi guys,

Do we need to install the one DAE on each different environments of the source system in order for it to communicate with different XI environments?

supposem the source system uses the same system for test and production and it creates file in two different folders for test and prod. and XI has 3 environments, dev, qa and prod. As we have only one source system, it means that we can isntall one DAE on it. Can the same DAE be configured with all the XI enviromments? if yes, how? If no, how can we test the interfaces in dev and QA?
