Decentralized/Standalone XI Adapter Engine in same SID as Central AE

For reasons of splitting functionality, we want to setup separate XI adapter engines (AE) so that we can "pin" certain communication channels to specific AE.
On top of the "Central" AE (installed in /usr/sap/<SID>/DVEBMGS39), I have now installed a second ABAP/J2EE dialog instance (in /usr/sap/<SID>/D89).
All the Java components and services are visibile in VisualAdmin.
D89 shows up in SLD, and the J2EE SLD Data Supplier in D89 works.
However, there seems to be no "separation" of the 2 instances of the AE:
In RWB, component monitoring, there are no entries under "Non Central Adapter Engine" (although it is visible as a second node in Adapter Monitoring/MDT)
In IB/DIRECTORY, only the "Integration Server" is visible as an "Adapter Engine" in the communication channels
In the SLD, the class "HTTP Service Port: Basic URLs of Adapter Engine on <hostname>" only shows 1 URL (pointing to D89 and not to the "central" DVEBMGS39l).
To me it seems the 2 J2EE instances (within the same SID) behave as 1 (just like if we added another server1 to the same J2EE instance).
I think the main problem is within the data of the SLD. Does the separate "Adapter Engine" need to be registred manually (for example by creating an additionale instance of the CIM class "SAP_XIAdapterFramework" ?
System has been restarted many times.
Has anybody setup a separate adapter engine this way ?
Thanks for your help
Kind regards,
Jan Van Achte

Dear Jan
did you find a solution for your problem ? i got the same problem and did still not find a solution in sapnet.

Installaing decentral Adapter Engine (Java EE) 7.1 Including Enhanc

Dear All
we are installaing decentral Adapter Engine (Java EE) 7.1 Including Enhancement package 1 on Linux with database DB2.To do installation we have followed the installation guide "Adapter Engine (Java EE) 7.1 Including Enhancement Package 1 on Linux: IBM DB2 for Linux, UNIX, and WindowsTarget"
Accoridng to that document "In the Welcome screen, choose the required SAPinst installation option under the node SAP EHP1 for SAP NetWeaver Process Integration 7.1Installation >OptionsOptional Standalone Units >Partner Connectivity Kit." we have followed the same.
The installation has been completed successfully.But to do post-installation activities the java url in not comming up.
,we have tried with physical host and ip address as well.From os level we have found that server0 process is in running status.
I am not sure why the installation guide is asking us to follow Process Integration 7.1Installation >OptionsOptional Standalone Units >Partner Connectivity Kit?
Will you please let me know whether this is the correct procedure for Installation of Adapter engine on Pi 7.1 EHP1
is there any prerequisite steps are there for adapter enginee
Thanks and Regards
ravikiran.CH

Hello
From your description, it appears that you have installed a PCK and not a decentral Adapter Engine.
I guess you need to follow Process Integration 7.1Installation
-> Optional Standalone Units
-> Adapter Engine
You can undeploy the PCK by following the steps in the note #1295094 Initialization of PI 7.1 XITOOLS fails.

Sender File Adapter Not Showing in Decentral Adapter Engine

Hi,
We have recently implemented a Decentral Adapter Engine on a windows box. The adapter engine seems to be working fine because my adapters show and seem to work fine in it.
However, when I define a Sender File Adapter that uses File Content Conversion message protocol instead of just File messaeg protocol, the adapter does not show up in the decentral adapter engine.
I made sure that Adapter Engine parameter in the Sender File Adapter shows the new adapter engine but that does not seem to be working. If change the Adapter Enginer parameter to show the Central Adapter Engine, then I can see the Sender File Adapter on the Central Adapter engine and it works fine. (Note: The Central Adapter Engine is installed on a Unix box)
Here are the paramters I defined for the Sender File Adapter:
- Transport Protocol: File System (NFS)
- Message Protocol: File Content Conversion
- Adapter Engine: (new Adapter Name)

Your help is much appreciated.

Hi Alaa,
look into this document:
http://service.sap.com/nw-howtoguides -> Exchange Infrastructure -> Troubleshooting: Adapter Engine 3.0 (Expert Call slides)
If the File Adapter works without conversion, then you should count the number of fields in a row. If it differs from the configuration, then it runs on error.
Another idea is to check the content type of the file. When you do not enter a File Encoding, then the file adapter assumes utf-8. If the file is for example latin-1, then the number of characters in a row are not counted correctly.
Regards
Stefan

Standalone adapter engine

Hi all,
Will SAP continue to support the Standalone J2SE adapter engine in future releases of SAP XI?
The J2EE adapter engine is quite "heavy" to use. It requires J2EE application server, Oracle database, quite some memory.
Actually, I like the standalone J2SE adapter engine. It is light-weight, easy to configure and manage, quite stable, ...
Kind regards, Guy Crets

Prasad,
"We will soon know": will SAP make its roadmap available in the near future? I definitely hope they continue to support the standalone adapter engine and even extend it. It seems unlikely to deploy the current J2EE adapter engine (or PCK) in a distributed landscape.
A related question: will it become possible to create proxies in non-SAP application server? Even better: Java proxies in a standard web container (e.g. Tomcat) or standard Java application (J2SE, non-J2EE).
Kind regards, Guy Crets

No_messaging_url_found: Unable to find URL for Adapter Engine

Hi,
I am facing the same problem. I have configured a RFC-File scenario.
I get the error"no_messaging_url_found: Unable to find URL for Adapter Engine af.<SID>.<server>"
and <INTERNAL.AE_DETAILS_GET_ERROR>
I get the error "no_messaging_url_found: Unable to find URL for Adapter Engine" when I execute the Function Module SAI_AE_DETAILS_GET.
This error occured in the line 235( sap_xi_adapter_services = sld_accessor->associators( iref = sap_xi_adapter_framework assocclass = 'SAP_HostedXIAdapterServi) of the FM.
The value is not filled and i get the error mentioned.
I have gone through thread and verified all the points mentioned.
I have checked SXI_CAHCE,there are no locked users in RSUSR200,
SXI_CACHE, Goto->AdapterEngine Cache, I have an entry af.<sid>.<server>
In SLD,Technical Landscape,Exchange Infrastructure I have the entry <SID>.<Server> against the Adapter Engine
But as was mentioned in the thread the line 241 of the Fucntion Module has 'adapterType' and not 'Adaptertype' as in the exchange profile.I did not try changing 'a' to 'A'.
Could you please let me know how to solve the problem.
Thanks in advance.

Hi Vani,
Check the pipeline URL in the SLD
Business System->URL
It should be
http://host:HTTPport/sap/xi/engine?type=entry
Just check this thread- may be useful-

Purpose of having central adapter engine

What is the purpose of having Centeral Adapter Engine when any WAS 6.40 has an adapter engine that can communicate de-centrally with the IS?
Regards
chandrakanth.K

Hi Chandra,
The Adapter Engine is a separate software or software component that is automatically installed on the Integration Server. In this case, we will call it as central Adapter Engine. You can also install the Adapter Engine separately on another host. This is then a non-central Adapter Engine.
By installing the adapter engine centrally on Integration Server, all the components like adapter engine, integration engine, mapping runtime etc will be at single place which increases the preformance.
In the case of non central adapter engine, where we will install the adapter engine at another system(may be in another place) which decrease your total server performance.
thanks,
madhu

SOAP Adapter at XI 3.0 Central Adapter Engine

Hello,
I'm trying to use the SOAP Adapter with the Central Adapter Engine. It works with the J2SE-Adapter Engine, but not with the Central Adapter Engine.
I Get the Error: No response Available.
Perhaps someone can help me.

The J2SE adapter is a relict from XI 2.0
You may still use it, especially for migration from XI 2.0 to XI 3.0, but it is recommended to use the J2EE adapter engine.

Non central adapter engine & adapter monitoring

Hi ,
we installed PI7.0 sp12,and can we see all the available adapter as a list in RWB and adapter monitoring if adapter engine installed as non central?
And we will see Adapter engine under Integration server if AE is centran and under non-central adapter engine if AE is non central ,right?
thank you,
Babu

I could see both Communication Channel monitoring as well as Adapter monitoring.
but once I click adapter monitoring I could see only JPR but not any other adapters.if I click CC monitoring there are no CC cos we havent created any yet.
I am asking like,if we see only JPR in adapter monitoring not any other adapter ,is that a error while doing the installation and configurations? or is that ok?
thank you for your reply.

How can I change adapter engine from Non central to central

My adapter engine is assigned as non central. However I want to have the adapter engine as part of the integration server.
If I look in the RWB, the adapter engine listed under the non central adpater engine. However I would like to move it under the Integration server Engine.
Can this be done or do I have to reinstall XI to get the adapter engine grouped with the IS.
Currenty componenets under the domain I have:
1) Integration which has Integration Engine, busines process engine and Mapping runtime.
2) Integration engine are blank, nothing underneath
3) non central adapter engine
my adapter engine here
4) j2se adpater nothing underneath
4) Tools
So what I want to do is move the Non central adapter engine to be underneath the Integration Server.
Any ideas how to do this....withoout a reinstall?
Thanks

Retrive SID of XI server from EJB used in decentral adapter engine

Hi Experts,
We have a requirement where we need to call an RFC from a EJB bean using load balancing. To do the JCO call, we need the SID of the XI system as an input parameter for the createConnection function.
The SID can be retrieved using System.getProperty("SAPSYSTEMNAME"), however, we need to know if this is called in a decentral adapter engine, whether the getProperty() function will return the SID of the XI server, when called from a bean used in the sender adapter of a decentral adapter engine.
Regards

> however, we need to know if this is called in a decentral adapter engine, whether the getProperty() function will return the SID of the XI server, when called from a bean used in the sender adapter of a decentral adapter engine.
The decentral adapter engine has its own SID. So you need another solution for retrieving the SID of XI server. Maybe a property file?

Decentral adapter engine questions

Guru's,
My customer's XI 3.0 system has interfaces to 30 partners, almost all using the SOAP adapter. It turns out that when XI sends a high volume of messages to one partner and this partner is not responding (system down, network issues, etc.) all messages to the other 29 systems are blocked/timing out in the soap adapter because this adapter cannot deliver it's messages to the misbehaving partner.
Therefor the customer wants to have a dedicated AE for business critical processes. They claim they need a decentral adapter engine to achieve this.
My question: is that the best solution in this case? The customer has a CI and DI on different hosts and thus already two AE. Can't they make use of that to split important/less important traffic to their partners?
Assume the DAE is needed anyway. We want to install that on the same hardware as the XI system itself, because most of the connectivity is already in place.
Question: Does this DAE need it's own SID or can it use the same SID as XI itself with a unique instance number? If the DAE needs it's own SID, then I need to create a database as well (+ backup + database maintenance)...
There is also the requirment to use 2048-bit certificates. The current XI 3.0 supports only 1024-bit, NW 7.00 supports 2048-bit. Is it supported by SAP to have a XI 3.0 system with a NW 7.00 Decentral Adapter Engine?
Thanks and Regards,
Rob Veenman
SAP Basis.

Hi Rob
I can't answer all your questions but I can offer some tips that will help improve the performance and perhaps you will not need to install the DAE.
1) you can increase the number of queues/threads available to the SOAP adapter. This will help with performance issues in high load situations.
See the blog: /people/kenny.scott/blog/2007/08/20/messaging-system-queue-properties-after-xi-30-sp19-xi-70sp11 for details on how to do this.
2) apply note #1136790 Blocking receiver channel may affect the whole adapter type. The parameter in this note will help prevent a problem with one SOAP channel, for example, blocking all your other SOAP channels. This will allow other interfaces to operate as normal if the high load interface has problems.
See the blog: /people/kenny.scott/blog/2008/12/05/xipi-file-and-jdbc-receiver-adapter-performance-and-availability-improvements
You should be on a SP higher than SP20 to avail of the functionalities in points 1 and 2 above.
3) also ensure note #937159 XI Adapter Engine is stuck. This will help with the Adapter Engine performance.
Maybe some of the other forum users can help you with your other questions.

Decentralized Adapter Engine

Hello,
We have installed an XI landscape (XID, XIQ, XIP) on Unix along with a single decentralized Adapter Engine on Windows (XD1) which is currently configured for use with our XID system. We would like to also use this same decentralized Adapter Engine with our XIQ system. However, when we export a communication channel from XID that is configured to use the decentralized adapter engine (af.XID.calxid1) and subsequently import the communication channel into XIQ the decentralized Adapter
engine that was configured in XID (af.XD1.calxid1) is
replaced with "Integration Server" (Default) in the Communication Channel configuration in XIQ. The pull down to choose an adapter engine shows only the (Default) Integration server as an available choice. Currently XID and XIQ are using the same SLD and the decentralized adapter engine (af.XD1.calxid1) is identified there. I have been unable to determine how to use the decentralized adapter engine with our XIQ system. Does anyone know whether it is possible to have multiple XI systems using the same de-centralized Adapter Engine? And if it is possible how does one configure the second XI system (XIQ) to use the decentralized adapter engine?
Thanks.

Hello Dan,
a decentralized AE can only be attached to a single Integration Server.

Decentral J2EE Adapter Engine

I am trying to install a Decentral J2EE Adapter Engine.
Please could someone tell me whether, when defining ABAP UME, should I define the same users as were defined on my Central PI instance for Admin & Guest, or should I use the suffix of the users as I receive in the default values on the screen ?

Decentral adapter engine & security

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-a32a119a582d
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?
<It is against the rules of Engagement to post a question with the catch of awarding points. Please refrain from the same.>
Edited by: Bhavesh Kantilal on Dec 3, 2008 10:26 AM

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.
