Cache Refresh Problem

Hi,
We updated XI 3.0 to SP4, and started seeing several problems related to Cache Refresh and JCo.
In the SAPGUI in transaction SXI_CACHE, we are unable to refresh the cache, and getting the following error:
Connection to system RUNTIME using application RUNTIME lost. Detailed information: Error accessing "http://NETWEAVER:50000/run/hmi_service_id_fresh_mappings/int?container=any" with user "XIDIRUSER". Response code is 503, response message is "Service Unavailable".
In SM59 for RFC HTTP destinations, the INTEGRATION_DIRECTORY_HMI test gives the HTTP/1.1 500 Internal Server Error. The URL is /dir/CacheRefresh.
On the Runtime Workbench, I am trying to run the self-test for Mapping Runtime. We get the following errors:
Ping Status: HTTP request failed. Error code: "503". Error message: "Service Unavailable"
Self-test status: HTTP request failed. Error code: "503". Error message: "Service Unavailable"
We are on XI3.0 SP4, J2EE SP7 and ABAP SP4.
What can I check on the J2EE server to see if the service is running ? And what can I do to fix the JCo connections ? Thanks,
Manish

Thanks Hart. I have updated the URL and it succeeds on Test.
However, I still have the Cache updation problem.
When I update an object (say, a mapping) in the Integration Builder, and activate it, the XI Server Cache should get updated with this new object.
On running the scenario, I am getting the following error as observed in the monitor (SXMB_MONI):
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">
<SAP:Category>XIServer</SAP:Category>
<SAP:Code area="XICACHE">UPDATE</SAP:Code>
<SAP:P1 />
<SAP:P2 />
<SAP:P3 />
<SAP:P4 />
<SAP:AdditionalText>HTTP status code401 Unauthorized</SAP:AdditionalText>
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>An error occurred when refreshing the XI runtime cache</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
To resolve this problem, I have to manually go to the transaction SXI_CACHE, and do a delta cache refresh. It asks for the user credentials everytime for XIISUSER.
Is there a way to automatically enable this user to enable the cache refresh in the background ?
thanks,
Manish

Xi Data Cache Refresh Problem

Hello,
We have following Problem:
We send an XML-Request with HTTP-Adapter to XI and get Data from R/3, works fine.
But when we send a Second Request we become an Error.
The error comes because in the Java Runtime the XI writes wrong values into Message.
When we do a XI Data Cache Refresh for INTEGRATION_SERVER
and INTEGRATION_RUNTIME we can send a message and all works fine again.´
Any Idea why the XI Caches Data from Request and set this values in the message of request that was send later?
Thanks,
Robin

Hi,
I think both are same. Because in SXi_ADM we also define our IS. so i think it may be same ...
If I am wrong please share your knowledge . in this thread for more clarification ..

Cache Refresh Problems:J2EE

Hi
I am facing a problem in cache refresh.
The XI 3.0 server is at SP10. Now whenever i am doing any changes in directory and activating it,it doesnt give me any error. but when i am cheking the Cache notifiactions it shows me a "GREEN" light for ABAP Cache and a "RED"(not yet started) light for Central Adapter Engine Cache.
Thus, in sxi_cache also i see a green light telling me that cache contents are upto date.
I tried doing a manual CPACache refresh by using
http://<host>:<port>/CAPCache/refresh?mode=full|delta , but it doesnt get completed.
Due to this my scenarios are not working currently and whatever changes i am making is not getting reflected.
Has anyone faced this...?
How can I solve this?????
Thanks in advance.
Regards
Sunita

Hi Sunita,
The following are required for a successful CPA-Cache refresh:
1.Correct maintenance of the users in the ExchangeProfile (Adapter Engine Service User and Integration Directory Service User)
2.Successful SLD self-registration of the URLs
3.Availability of SLD
Check the "Problems" tab of the cache notifications overview in the directory. If there is a problem with an incorrect communication then it will be shown in this tab.
Let me know what the "Problems" tab says.

Cache Refresh Problem in SXI_CACHE Transaction in new client 700

Hi Experts,
    We have installed and configured the new PI7.1 server and were checking its readiness by going through the Readiness Check Document. At one stage while we run the transaction SXI_CACHE in client 700 we are not getting the option of " Start Complete Cache Refresh" in highlighted mode. Thus we are not able to refresh the cache in client 700. But if I login in Client 001 and login using SAP* and run the SXI_CACHE I am able to see all the pipeline steps as well the option for complete Cache refresh and Adapter cache referesh is in Highlighted mode. The status is also green. Can somebody us in knowing where should we look into to solve this problem so that these option are available in the new client for refershing the CACHE.
Thanks

Problems in SLD and Cache refresh (SXI_CACHE).

Dear Experts,
I am facing SLD and Cache refresh problems in PI 7.0 on HP-UX.
1) SXI_CACHE : Last Error During Cache refresh is showing LCR_GET_OWN_BUSINESS_SYSTEM - NO_BUSINESS_SYSTEM error. And also Start Delta Cache Refresh / Start Complete Cache refresh are in deactive mode (Frozen).
2) SLDCHECK : Log says No Business System for ABC Client 100 ".
where ABC=SID. Business System INTEGRATION_SERVER_ABC is declared in SLD and client 100 is assigned.
My question is : Is this a BASIS or DEVELOPER issue? Also please let me know if you have any solutions for the above mentioned issue. Thanks in Advance.
SLDCHECK Log Snippet:
SLD server access settings:
host name: ABCXIDEV
port number: 50000
user : PIAPPLUSER
Use transaction SLDAPICUST if you wish to maintain the SLD server access data
Launching the SLD GUI in a separate browser window...

Retrieving data from the SLD server...
No corresponding business system found for system ABC client 100
=> Check and maintain the SLD content for the current client

Hello,
Since this is an PI system, your XI consultant must have created/will need to create business systems in SLD for the scenario to work properly. This error is because it cannot find the business system.
You cannot point out the fingers on Basis or XI and say that it is THEIR issue. Please consult with the consultant who is doing the XI interface and check if the business systems he require are properly created in SLD. If not, create them or ask them to create it (if they are allowed to..).
From the error, what i can see is that you have defined an integration server INTEGRATION_SERVER_ABC in SLD . the XI interface is checking the required business system in the integration server INTEGRATION_SERVER_ABC in SLD but cannot find it over there. Please check the integration server INTEGRATION_SERVER_ABC in SLD and talk to the XI consultant and you will be able to fix this with their help.
Hope this helps you..

Cache refresh error, while activating changelists

Hi all,
I got a problem, concerning XI Runtime Cache on XI 3.0, SP15 -> when I try to activate changelists from Integration Directory, (SOMETIMES!)XI_CACHE shows status: Error, while refreshing cache
with Errortype: Communication,
"if_http_client receive http_communication_failure"
When I then do a delta or full cache refresh from transaction SXI_CACHE it allways works, even after an error occured before. Some ideas, what I could check?
Thank you in advance..
Daniel

Hi,
Just check with Tcode SICF and check for all the services are working fine.
Go thru following links

Cache Refresh for Adapter Engine is not working

Hi,
our adaper engine is not working. At RTW no there are no channels visible and the button "Test Cache Connectivity" leads to a yellow icon for the adapter engine with the error text: "Attempt to fetch cache data from Integration Directory not yet started or still in process".
The error reason is at http://<j2ee host>:<port>/CPACache/history.jsp available: com.sap.aii.af.service.cpa.impl.exception.CPADirectoryCacheException: Couldn't open Directory URL (http://pixd1.digoff.no:55200/dir/hmi_cache_refresh_service/ext?method=CacheRefresh&mode=C&consumer=af.xd1.dat-dof-xi), due to: HTTP 403: Forbidden
The cache refreh request from adapter engine to directory gets an 403 error. What is strange: No problem, to execute that request in a browser, i get the right message, no fault.
I searched for notes or other threads, i could find only <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_bc_xi/~form/handler%7b5f4150503d3030323030363832353030303030303031393732265f4556454e543d444953504c4159265f4e4e554d3d373531383536%7d">SAP note 751856</a> , but it is valid for XI 3.0; we are on PI 7.0.
I checked out:
- no user blocked
- all system users have standard authorisations
- reimport of SAP BASIS SWC
- SICF services for XI active
- destination INTEGRATION_DIRECTORY_HMI working
Any idea, how i can get the adapter engine working?

Udo

Hi,
There are two ways to display the content of the CPA cache refresh.
1. The Cache-Update Content-XML
Document can be stored in the Adapter Framework database (J2EE schema) for further analysis. Here you have to set the property in the J2EE Visual Administrator tool.
To do so, proceed as follows:
=>J2EE-service SAP XI AF CPA Cache
=> set property trackCacheUpdateXML= true
=> You can now display the cache update XML with the alias CPACache
=> View Cache Update History
=> View Cache Update XML
2. The content of the cache refresh from the Integration Directory intothe CPA cache can be written to an XML file: Here you have to set the property inthe J2EE Visual Administrator tool:
=>J2EE-service SAP XI AF CPA Cache
=> set property J2EE service SAP XI AF CPA Cache cacheUpdateDebugFile = true
=> the CPA cache refresh XML file will be in the server(0) directory search for the following file names:
=> value of the property cacheUpdateDebugFile.deltaif you intend to see the delta refresh accordingly and the value of the property cacheUpdateDebugFile.full if
you intend to see the full cache refresh content
Note: After your analysis, do not forget to reset the properties value to false.
You can delete the XML cache-
refresh table: alias CPACache
=> View Cache Update History
=> Delete History
Also check out the user and its permission.

Error in INTEGRATION_DIRECTORY_HMI and CACHE REFRESH

Hi guys, well after checking the forum and several blogs i can't get rid of my problem!
I have a problem concerning INTEGRATION_DIRECTORY_HMI and CACHE REFRESH.
i wanted to get a file from a FTP-Server via CC and i got error:
<SAP:AdditionalText>Error when reading HTTP destination: INTEGRATION_DIRECTORY_HMI.</SAP:AdditionalText>
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>Error while refreshing the XI runtime cache</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
Because of this i tried to update my cache (SXI_CACHE). When i do a Delta Cache Refresh i get:
Prefix Number: entry missing for system SSID client 100.
When i do a complete Cache Refresh nothing happens at all. I also checked the cache notification in IB - Integration Directory where i fin dout that only the Integration Server (ABAP Cache) won't refresh. Well status is started but nothing else is happening.
Then i checked the RFC INTEGRATION_DIRECTORY_HMI, did a connection test where i get an Internal Server error.
Let me tell u that the systems runs very well in the last days but now i have no clue what might be wrong.
Can somebody please advice me? I already read all blogs concerning this and also did a complete system-restart....
br Jens

when you check INTEGRATION_DIRECTORY_HMI with SM59 it is normal to get
HTTP Response 500 - Internal Server Error. In this case it meens everything OK
see the rediness check, that is attached to SAP note 817920
when you start the complete cache refresh, you can see
the function module SAI_CACHE3_REFRESH_BACKGROUND in SM58. As long as you can see this entry, the cache
refresh is ongoing. If the refresh takes too long and runs on an error, try to specify another timeout in INTEGRATION_DIRECTORY_HMI or in the ICM

Is CPA Cache refresh linked with ftp or file pooling process in XI?

Hi,
I have a file to file scenario using Transport protocol as FTP in XI 3.0 SP 15.
When we try to sends some file using ftp protocol where we are using
FTP connection parameters
Server = <CORRECT IP>,
Port = 21 ,
User name <CORRECT NAME>,
Password <PASSWORD> ,
Data Connection = Active
Connection Seq = None
Connection Mode = Permanently
Transfer Mode = Text
Processing Parameters
Quality of Service = Exactly Once
Pooling Interval = 1 sec
Processing Mode = delete
File Type = Text
File encoding = utf-8
The problem we are facing like some time the ftp is not working even the file is present in the location for pick up. If few files are stacked up to be collected then when we are using CPA Cache refresh in Full mode manually then it fetches all the files from the location but the problem is that ,we have a time constraint for this process to be completed in just 60 seconds if we are not able to pick up a file in 60 Secs then the file will be treated as invalid.
So I just want to know how Manual CPA CACHE refresh in full mode generally solve the problem.
Next if more files will be stacked up then cache refresh also failed to solve the problem and more cache refresh result in NOT pooling any other files in XI including the above discussed flow.
So,in anyway Cache refresh linked with ftp or file pooling process in XI?
Please assist me in correctly understating the whole problem and what solution could be put to solve this.
Thanks,
Satya
Edited by: Satya Jethy on Mar 14, 2008 12:28 PM

Hi Suraj,
If you see my query i have mentioned that the pooling interval is 1 Second.
If we are not able to pick the file with in 60 Secs as this is a real time scenario so the file will be treated as a invalid file.
Moreover this problem is happening some time.
I have also checked the component monitoring it is saying everything is ok as because we are receiving the file with out any error and the file transfer is also success.The only problem is that it is not collecting the files from the given location.
Hope i make you understnad the problem .If not please revert back i will try to explain once again.
Thanks,
Satya

J2EE RFC Metadata cache refresh

Hi All,
I've searched a bit on this forum but can't quite find the answer I'm looking for...
Is it possible to perform a cache refresh without having to restart the server, after making changes to an RFC model and deploying it? It's a pain in the neck to have to keep restarting DEV, QA and PROD everytime we move something through the CMS that has changes to models.
I would have thought the assembly step from consolidation to production would have solved this problem but it doesn't.
Thanks,
Gareth.

Hi Arun,
I understand what is happening and how it works and why... I was simply asking if there is a way to refresh the J2EE cache without restarting the server?
I think this is something we really need included in future SP's as it is a pain. As mentioned, I would have throught the assembly/import step in the NWDI CMS would have done something to refresh the cache when an SC is imported into the Production system.

Adapter Cache refresh doen't work with XI3.0

Hi,
We are running XI 3.0 / Oracle 9.2 on Linux SUSE SLES8
and we have a problem with the Cache refresh of the adapters.
Somehow the status of the cache remains 'Red', without an error message.
Anyone any ideas?
Björn

Thanks Bill,
Yes we logged into that and it shows error there (RED) and it doesn't get refershed there too. The XML error message shows the following:
com.sap.aii.af.service.cpa.impl.exception.CPADirectoryCacheException: Couldn't open Directory URL (http://vd06cs01.sce.com:50000/dir/hmi_cache_refresh_service/ext?method=CacheRefresh&mode=C&consumer=af.d06.vd06cs01), due to: HTTP 503: Service Unavailable
Please advice, it's a very high priority issue.
