Problem while creating JCA connection to MDM server

[Former Member]

Hi All,

I have restarted my mdm connector(com.sap.mdm.tech.connector) along with the applications related to Enrichment Controller. All applications restarted successfully. After that I tried accessing the URL

http://MDMSERVER:50000/MDM_EnrichmentController/WorkflowPolling?process=Monitor

but I am getting following exception in this page

Polling Repository

name=Vijaybabu_Repo_on_MDMSERVER, status=No repository connection, error description=com.sap.mdm.net.ConnectionException: Problem while creating JCA connection to MDM server MDMSERVER

Enrichment Request Threads

Could somebody help me pointing if something I have missed..

Thanks and Regards,

Manoj

hi

Is your repository loaded? If yes, better check if it has any errors/warnings in Console?
