Verifying a data source connection
Many connection problems can be easily fixed by verifying configuration parameters. There are steps that you must complete to enable a successful connection.
About this task
If your connection is still not
successful after completing these steps and reviewing the applicable
information, check the SystemOut.log for warning or exception messages.
Then use the technical support search function to find known problems.

Note: This topic references one or more of the application server log files. As a
recommended alternative, you can configure the server to use the High Performance Extensible Logging
(HPEL) log and trace infrastructure instead of using SystemOut.log ,
SystemErr.log, trace.log, and
activity.log files on distributed and IBM®
i systems. You can also use HPEL in conjunction with your native z/OS® logging facilities. If you are using HPEL, you can access all of your log and trace
information using the LogViewer command-line tool from your server profile bin directory. See the
information about using HPEL to troubleshoot applications for more information on using HPEL.
