hmi_cache_refresh_service not working

[Former Member]

When I activate a communication channel in ID I get an information message saying "Attempt to determine which Adapter Engines are affected by data changes failed". When I look at the log it says "CPA Cache not updated with directory data.". The detailed trace is

com.sap.aii.af.service.cpa.impl.exception.CPADirectoryCacheException: Couldn't open Directory URL (http://mbsdalxi50.miller.americas.gcn.local:50000/dir/hmi_cache_refresh_service/ext?method=CacheRefresh&mode=C&consumer=af.xid.mbsdalxi50), due to: HTTP 503: Service Unavailable

The HTTP connection & services are OK. I re-created the HTTP connection and bounced the server for couple times.

When I look at the RWB--> Component Monitoring --> Adapter Monitoring, I see most of the adapters (File, JDBC etc) are greyed out. We are on XI 3.0 SP14, we did not applied any Service packs recently too.

I appreciate ypu help in this issue.

Thanks.

Hi,

Check this SAP note- 764176,741214

Also check SM59->RFC destination type "H" test connection in XI system

Also refer this Cache Refresh Guide-

>>>For this check Adapter Metadata are imported into the Repository.(SAP BASIS Component)

Hi Krishna Moorthy,

Thanks for your quick response.

I checked the SM59 for RFC destination type H and the test connection works OK, I get a code 500. I did the full refresh & delta refresh couple of times. But did not work. All the adapter Meta data under SAP Basis components exists in IR. I checked the OSS notes and the pdf document that you sent, but was unable to find a solution.

Thanks.

Hi

CHeck these-SAP Note- 803145

Also this-

Go to SLD->Business System->integrationServer and check for the Pipeline URL- it should be like this

<i>http://<hostname>:port/sap/xi/engine?type=entry</i>

Also check SLDCHECK Transaction. check this configuration guide about this-

The Messaging system and messaging servlet are active. http://mbsdalxi50:50000/MessagingSystem/receive/AFW/XI

In SLD the pipeline URL is also correct. SLDCHECK transaction works fine. The system was working fine for last one Year. Suddenly from couple of days the CPA Cache is not getting refreshed. This is happening in Development & system test boxes. Production is good. We have one Central SLD.

Thanks.
