Hi Experts,
Post upgrade of BI Portal (from 7.0 to 7.31), some tabs when clicked shows "Java communication error: An unknow error occured during Portal Communication" & "A nested exception occured. Could not execute the function" & "Could not connect to back-end system" errors
Checked default trace and it shows
"com.sapportals.connector.connection.ConnectionFailedException: Connection Failed: A nested exception occurred. Could not initialize physical connection. Connection Failed: A nested exception occurred. Could not initialize physical connection. Connection Failed: A nested exception occurred. Could not create JCO connection. "
Please Help to solve this.
Thanks,
Preetha Balan
