Steven Hawkins commented on TEIID-4945:
---------------------------------------

> TEIID40007 Keepalive failed for session RiZrctKFJYxl

That would be unrelated to this issue.

> I there is a guy that says it come from line 456 in JDBCConnectionManager

It makes me think that your client code is using a DatabaseMetaData result set and asking for a column by column name, not by the label.  If your client logic is old see also TEIID-1651 - there is a flag that can alter how the metadata is reported.

> This java client uses ontop to make the mapping from a db to a ontology. I had prior version where i was mapping my data from a postgres db to the ontology using ontop, in my recent version i changed the db to a teiid db(where i get the error). 
> Using teiid 9.2.3 and wildfly with java client with 9.2.3 driver i get this error: 
> {color:red}Error obtaining the Metadataorg.teiid.jdbc.TeiidSQLException: Column name "VDBName" does not exist.
