I am trying to load some data into a table in my dashDB database but hit an error message. Can I download db2diag.log from the dashDB console to find out what has happened?
com.ibm.db2.jcc.am.SqlNonTransientConnectionException: [jcc][t4][10335][10366][4.18.60] Invalid operation: Connection is closed. ERRORCODE=-4470, SQLSTATE=08003 Data loading failed.
As Jeff said, you can't access the logs of this DBaaS as it is shared resource. You will need to debug from your applications side. Are you maybe having a contingency problem with passing around the connection handle? Can you share your code?
