Troubleshooting overview
Troubleshooting is the process of finding and eliminating the cause of a problem. Whenever you have a problem with Z and I Emulator for Web, the troubleshooting process begins as soon as you ask yourself what happened? A basic troubleshooting strategy at a high level involves:
- Recording the symptoms.
- Recreating the problem.
- Eliminating possible causes.
- Using diagnostic tools.
Recording the symptoms of the problem
Depending on the type of problem you have whether it be with your application, your server, or your tools, you might receive a message that indicates something is wrong. Always record the error message that you see. As simple as this sounds, error messages sometimes contain cryptic 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.
The Z and I Emulator for Web Troubleshooting Guide provides more information about using messages to determine the cause of a problem.
Recreating the problem
Think back to what steps you were doing that led you to this problem. Try those steps again to see if you can easily recreate this problem. If you have a consistently repeatable test case, you will have an easier time determining what solutions are necessary.
- How did you first notice the problem?
- Did you do anything different that made you notice the problem?
- Is the process that is causing the problem a new procedure, or has it worked successfully before?
- If this worked before what has changed? The change can refer to any type of change made to the system, ranging from adding new hardware or software, to configuration changes to existing software.
- What was the first symptom of the problem you witnessed? Were there other symptoms occurring around that point of time?
- Does the same problem occur elsewhere? Is only one machine experiencing the problem or are multiple machines experiencing the same problem?
- What messages are being generated that could indicate what the problem is?
