Adapter Engine Cache Issue

Hello All,
In SXMB_MONI i got an error saying
SAP:AdditionalText>Error while writing to secure store: ERROR_UNKNOWN: Error when updating buffer for Adapter Engine</SAP:AdditionalText>
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>Error while reading access data (URL, user, password) for the Adapter Engine</SAP:Stack>
My Analysis :
1, In SXI_CACHE i could see 'Unable to refresh cache contents' and 'Error during last attempt to refresh cache' also I could not see any entry in Adapter Engine Connection Data Cache.
2, when execute the RFC connection 'INTEGRATION_DIRECTORY_HMI' Its asking for userId and password .
3, I tried reset the password and do a JAVA restart again with same error.
Clarificaiton need :
1 Looks some authorization error , but where exactly to maintain this ,
2, How the adatper engince connection data will populate in to sxi_cache transaction.
could you guide me clearly for this issue.
Regards.
Sethu.

Pls check the OSS note - Note 1319873 - PI CTC: Error in "Executing BAPI SXMB_SET_ROLE_TO_IS"

Check the parameters as suggested by others for this destination type.
Check the USER which is mentioned for this RFC destination is locked or not? if so please unlock it.
Try to change the pwd for this user and try again..

Adapter Engine : Cache Connectivity Test

Hi,
We have recently migrated our PI system's database from one host to the other and as a result there were some duplicate entries for exchange infrastructure components in SLD.
At this besides other problems we have noticed the Adapter Cache Connectivity test is failing.
We have deleted these entries and check that all the required entries are there and they are correct.
After this we did the Adapter Engine Cache connectivity test it still failed. But after some time we noticed that the connectivty test is successfully happening without doing any changes.
We see green bulbs with cache notification from integration server received successfully and cache data fetched successfully and update.
We are just wondering how it happened ? appreciate if anybody can help us understand.
Thanks & regards

Adapter engine URL different between CACHE and RWB adapter engine URL?

Hi there,
If I go to SXI_CACHE and go to the adapter engine runtime cache I get a URL of:
https://<server>/MessagingSystem/receive/AFW/XI
NOTE: The above URL is HTTPS.....and there is no port in the above....
However, if I go to the runtime workbench and click on the adapter engine and click on "test message", I get the following URL:
http://<server>:<port>/MessagingSystem/receive/AFW/XI
NOTE: The above url is HTTP and there is a port.
How can I get these URL's back in sync?
I want them both to be HTTP.
Any ideas?
Thanks

Hello
1) Check the value of the Exchange Profile parameter 'com.sap.aii.connect.secure_connections'. If you don't wish to use HTTPS this should not have any value set.
2) Delete the Adapter Engine cache in trx sxi_cache -> Goto -> Adapter Engine Cache -> Delete Cache Contents (trash can icon).
The AE cache will be populated the next time a message is sent through the system. Check the value after this is done.

Mark

Adapter Engine Issue in RWB

Hi,
I am getting a error in the RWB:
Self-Test Status: HTTP request failed. Error code: "500". Error message: "Internal Server Error [http://host:port/AdapterFramework/rtc]"
I have a mail channel setup that is running on this Adapter Engine. I am able to monitor the channel on this Adapter Engine and the channel is collecting mails from the POP3 mailbox and delivering the message to the Integration server. However I am getting the error above.
Please can you assist to get this matter resolved.
Many Thanks
Regards
Willie Hugo

Hi,
This problem is still persisting. I have however not mentioned that we are running PI 7.10 and therefore there is no Visual Administrator only NWA. This was a new install. I have changed all the Host Names to use fully qualified domain names. This is the exchange profile and sxmb_adm, RZ70, sldapicust and in the RFC's user on the ABAP side. Also I have checked out the destinations on NWA and changed the Host Names the to fully qualified domain namesand also the SLD Data Supplier Configuration. I also changed the FQ D names on the JCO RFC Destinations. All well so far.
I however still has the same error on the Adapter Engine in the RWB. What I have notice though is where the error is displayed in the RWB then the Host Name is not FQ. Where can I correct this?
Also I have noticed when going into SXI_Cache > Goto > Adapter Engine Cache then there is no cache for the Adapter Engine.
I have changed the host name of the integration server on the SLD to FQ D names as well.
I think that I need to delete all the entries for this tech+business system and all the assosiations to it from the SLD and then re-register the whole PI to the SLD again, but is not sure how to do that again.
Please can any one assist.
Regards
Willie

No entry for adapter engine in CPACache

Hi all,
This is a new installation of PI 7.0. Some of the issues we are facing are:
1) ID -> cache notifications -> unable to determine the name of central AE from SLD
2) Integration Builder -> Admin -> cache overview -> refresh objects fails
3) RWB -> Cache connectivity test for AE fails
4) SXI_CACHE -> goto Adapter Engine Cache -> No Entry under Adapter Engine Connection data cache
5) RWB -> Adapter Monitoring : Only JPR is shown. All the adapters need to be shown as well.
6) SLD -> Technical Systems -> XI -> Integration server does not show the domain name. But all other components have a consistent domain name.
It seems to me that somehow the adapter framework hasnt been registered in the SLD. Do we need to do this manually?
Any help on any of the above issues is greatly appreciated..
thanks!

Hi Lasya,
Please have a look at this thread..

Unable to Find out Adapter Engine in the Communication Channel

Hi Experts,
I am Unable to select the Adapter Engine As Integration Server in the File Sender Communication Channel.
Please Let Me Know
Regards
Khanna

HI Khanna
Check the SLD that Adapter Engine is insatlled and all the adapter has the metadata there.
Go to Transaction Code SXI_CACHE in the Inetgration Server(XI- ABAP stack) Then you can see the list of components.
Just have a look into Menu Bar - in there goto : GoTo->Adapter Engine Cache ( if the status is green - then it is correct-otherwise you need to refreshit.)
You just go thru mentioned document from service.sap.com/nw04
You will get the full info about that.

Just try with Visual Administrator to check the services for the adapter engine are running or not
All services starts with SAP XI..
SAP XI AF Core
SAP XI AF CPA Cache
SAP XI AF Messaging
SAP XI Adapter XI
SAP XI AF Security
Check SAP note on CPACache- 741214 and also 824236.
Let me know if any errors..

Adapter Engine Load balancing for Messages HTTP SOA/SOE

Greetings all,
We are currently implementing our SOE/SOA solution utilizing SAP services between a .Net Application. Basically .Net -> PI -> ECC and back.
We are load testing the system and are now experiencing the CI getting overloaded.
We have upped the Thread Count (Thread Manager 350 and System Threads 120) and the Queue thread from 5 to 20.
We are using SOAP with Principal Propagation.
There is a hardware load balancer we are using which can spread the load between multiple application servers. We modified the SLDRegistration host and ports (http/https) in Visual Administrator (SAP XI AF CPA Cache) in the global server node.
In SXI_CACHE Got -> Adapter Engine Cache, it displays http://<sidms>:<port>/MessagingSystem/receive/AFW/XI
Is this where the load balancer should be placed with the port name?
Any help would be appreciated.
Thanks

Hi Rocco
For switch over environment setup look at SAP Note 774116
Did you referred High availability guide

URL for Central Adapter Engine

Hi,
It seems like our XI Server is unable to locate the Central adapter engine for doing an outbound RFC call. I am trying to call an RFC using the RFC adapter, and getting the following error:
<SAP:Code area="INTERNAL">AE_DETAILS_GET_ERROR</SAP:Code>
<SAP:P1>af.nw4.netweaver</SAP:P1>
<SAP:P2 />
<SAP:P3 />
<SAP:P4 />
<SAP:AdditionalText>no_messaging_url_found: Unable to find URL for Adapter Engine af.nw4.netweaver</SAP:AdditionalText>
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>Error when reading the access data (URL, user, password) for the Adapter Engine af.nw4.netweaver</SAP:Stack>
Where do we maintain the URL of the adapter engine ?
thanks,
Manish

I have the same problem since we changed the name of the database server - the server name reported in the error is the old name. I've checked all the properties in this thread, plus follwed through OSS note 764176 with no luck. All the properties reflect the new name, but testing the proxy (SPROXY) still fails with the error:
<CODE>INTERNAL.AE_DETAILS_GET_ERROR</CODE>
<ERRORTEXT>Error when reading the access data (URL, user, password) for the Adapter Engine af.xix.sapsbxcrmdb2</ERRORTEXT>
sapsbxcrmdb2 is the old database server name.
I found one location where this is displayed - in transaction SXI_CACHE (in the client of th integration server), Menu option GOTO -> Adapter Engine Cache. The column 'Adapter Engine Name' reflects the incorrect name. Where is this property stored?
I cleared this entry manually by selecting the row and clicking on the trash can icon. Later it was refreshed properly.
-Mike
Update: I found that the SOAP Reciever channel in my Integration Scenario had a hard-coded entry pointing to the old integration server name in the property 'Adapter Engine'. I changed this by selecting the 'Integration Server' in the drop down. This changed the error behavior (still doesn't work, but the above errors went away).

Configuration Steps for Decentralized Adapter Engine

Hi all,
What all configuration steps are required to make Adapter Engine as
Decentralized AE.
I have made required changes in SLD DataSupplier in Visual Administrator.
what more configurations have to be done? On SAP XI Server and Decentralized
Adapter Engine.
With regards
Prasad

Prasad,
After configuring SLD data supplier in Visual Admin, you need to the following
1) Configure the gateway service for the central integration server on adapter engine host.
2) Perform Initial adapter engine cache refresh
3) Trigger data transfer to SLD
4) Check the connection parameters in exchangeProfile
5) Create HTTP destination pmistore in java environment
you have to go through all these tests for decentralized adapter engine. If you have XI configuration guide, it has all these steps in detail for you to configure

No Adapters visible - no connection to Adapter Engine

Hi - again i start a post.
We have problem that we have no adapters in CC-Monitor but Adapter Engine status is green.
Therefore we treid to refresh Cache which run fine, except when we Go To --> Adapter-Engine-Cache - nothing is shown.
In Integration Diretory we get error like:
Unable to contact Adapter Engine "af.px1.sapru03" that is affected by the data changes
http connection to "http://sapru03:50000/CPACache/invalidate" returns the status code "503" in response
and for Java Cache:
Unable to notify integration runtime (Java) of data changes
http connection to "http://sapru03:50000/run/value_mapping_cache/ext?method=invalidateCache&mode=Invalidate" returns the status code "503" in response
We already checked user in SU01 if locked, but is not.
When trying to access cache via http://host:port/CPACache/refresh?mode=full
we receive an 403 with PISUPER oder PIISUSER.
Can somebody help how to register Adapter Engine perfectly?!
br

Hi, ok i read this before.
1. We have no PCK installed so no need to undeploy.
2. CacheType Property is set to DIRECTORY and uses PIAFUSER as user (is this right?)
3. We get http 403 while calling <http://<host>:<J2EE-Port>/CPACache/
4. For calling /CPACache/refresh?mode=full we get following error (let me tell you that this is first time this call runs and gave back information!):
Negative confirmation:
<?xml version="1.0" encoding="UTF-8"?>
<CacheRefreshError>
