Unable to refresh cache contents

[Former Member]

Hi, well the above is my problem!

I changed a communication channel, activate it and now it's like this....

SXI_CACHE says:

Unable to refresh cache contents

Error during last attempt to refresh cache.

Also i get "if_http_client send http_communication_failure"

I checked INTEGRATION_DIRECTORY_HMI Destination, there i can see that the PW Status is "invalid". Connection Test therefore is not possible

How can i change this and how to solve this problem?! It's really urgent because no message is processed through XI!!

Hi, I think the problem is cuz the users lock, Could you please check the Cache History, and see if some of the red lights had some useful information? http://xi.company.com:50000/CPACache/history.jsp.

check all the PI* users locked and then take a look to this SAP Note in order to change the passwords and not to ge them locked. 721548

Hi Jakub, when executing this report i get

"CX_AI_CACHE_XM"

no idea what this means.

In INTEGRATION_DIRECTORY_HMI the Timeout is set to 900 msec. since the installation of the server!

I have no idea why refresh now is not working anymore. It's only in IB Directory in Repository everything is green!

Any other ideas?! XI does not process anything rigth now!!

EDIT:

The User PIISUSER is not locked and i have no idea why the PW is now invalid!

When i try to log in in Backend SAP-System with PIISUSER and PW it all runs fine....

so what's the problem?!

Did you check the password in the RFC destination?

I already restarted!

Well i did SLD_CHECK and found out:

No corresponding business system found for system DX1 client 100

i checked the SLD entries and what's that, the Dev system DX1 is now two times in the SLD.

No idea what happens, the new system occurs this noon. I deleted it and now i thought maybe it's alright but nothing!

Does someone has some similar experiences?!

Hi,

Have you tried to delete the RFC dest. INTEGRATION_DIRECTORY_HMI and recreate it?

Hi, can somebody please help me?!

After trying to solve the problem the messages are now recorded and ready to commit! Sometimes they are processed but mainly they are recorded!

The SXI_CACHE once said cache is well, now its again an error while attempting to refresh the cache!

What to do?!

Hi Dominic.

I did all you guys suggested. Finally i found out that un RWB the Adapter Engine is also not listed.

I have the impression as sth is wrong in SLD Content. Therefore i also checked OSS Note 764176 and follow all steps in detail.

As result nothing new happens.

Also i found out that the PIISUSER becomes locked after sometime - no idea why. This user is used to do the cache-fresh and also listed in RFC-Dest. INTEGRATION_DIRECTORY_HMI.

At the beginning of the day all seems fine, messages were processed. But when i started adding object in IB Directory and tried to activate the change list, the inconsistency occurs again! it's only the ABAP-Cache as the IB Directoryis telling me in cache-notifications.

What else can i do? thx for ur help!

Hi,

PIISUSER has the profile SAP_XI_IS_SERV_USER_MAIN.

The Delta Cache Refresh is not working properly. Before the problems occured i haven't have to enter User and PW to refresh the cache. Now i have to - no idea why!

I also followed https://websmp204.sap-ag.de/~sapdownload/011000358700003163902004E/HowTo_handle_XI_30_Caches.pdf

in detail - but with no success.

I have still no idea what might be wrong....

[Former Member]

[turmoll]

Can you please do it one more time: delete the RFC dest. INTEGRATION_DIRECTORY_HMI and recreate it?

Please report if it helped ...

Hi, thx for ur input but will this change the Password status from invalid to valid?!

[Former Member]

Hi,

make sure that you chose the right password for the user (XIISUSER??) in the RFC destination...

Maybe this user is locked.
