Unable to connect to host error 81015 when logging into IBM InfoSphere DataStage (DS): Failed to connect to host: <hostname>, project: UV  (The connection has timed out (81015)) 

The WebSphere DataStage server has a centralized file for storing environment variables called  dsenv  in $DSHOME. $DSHOME identifies the WebSphere DataStage installation directory. The default directory is /opt/IBM/InformationServer/Server/DSEngine. You might need to add new environment variables as you configure WebSphere DataStage to connect to different databases using plug-ins or ODBC drivers. Any environment variables you need for interactive use of ODBC drivers to make a connection to an ODBC data source must be added to the  dsenv  file. This lets the WebSphere DataStage server inherit the proper environment for ODBC connections. For a connection using a wire protocol driver, there are no changes required to dsenv.
