Troubleshooting is the process of finding and eliminating the cause of a problem. Whenever you have a problem with your IBM® software, the troubleshooting process begins as soon as you ask yourself "what happened?"
Depending on the type of problem that you have, whether it be with your application, your server, or your tools, you might receive a message that indicates that something is wrong. Always record the error message that you see. As simple as this sounds, error messages sometimes contain codes that might make more sense as you investigate your problem further. You might also receive multiple error messages that look similar but have subtle differences. By recording the details of each one, you can learn more about where your problem exists.
