Hi Uday,

Check cache connectivity test in RWB also cache in SXI_CACHE.

Hi Uday,

Can you please check if the HTTP destination INTEGRATION_DIRECTORY_HMI is working fine in SM59?

Regards,

Sanjeev.

Hi Sanjeev,

While checking the INTEGRATION_DIRECTORY_HMI in SM59, It is showing HTTP response code as 500. I dont think we have a problem here.

Please check if the PI system users are not locked and they have all the required authorization.

Aldo check the roles of the user used in INTEGRATION_DIRECTORY_HMI.

are you not getting a message along with the red status while doing cache connectivity test?

Hi,

You can check cache connectivity in RWB for all the components.

Go to RWB->Component Monitoring -> Display and then click on Cache Connectivity Test. Next page will show you all components and it should be green. If not test connectivity from here. If failed, contact your basis team to set it up.

Hi Aashish,

I am the only person who is handling XI activities. May I know how to solve this issue. I am getting it as red during the cache connectivity test in the RWB.

Hi,

Please check "PI Readiness Check" and "Admin Check" guides available on SMP and follow the steps mentioned there.

Thanks.

Hi Aashish,

Thank you very much for your information. I will ask our Basis guys to check this. Once it is fixed, I will close this thread.
