Detect problems

Use this information to find out how you can detect problems.

There are several ways you can detect that problems have occurred on your system. Most of the time, you will receive a message or system reference code (SRC). You can also use message queues and logs to gather more information.

• System reference codes
  A system reference code (SRC) is a set of eight characters that identifies the name of the system component that detects the error codes and the reference code that describes the condition.
• Messages
  Messages are communications that are sent from one person or program to another.
• Message queues
  A message queue is like a mail box for messages.
• Logs
  The i5/OS™ licensed program records certain kinds of events and messages for use in diagnosing problems.
• Watch for event function
  The watch for event function enhances your ability to detect and react to problems represented by specific messages or Licensed Internal Code log entries. The watch for event function notifies you when the specified event (message or Licensed Internal Code log entry) occurs, and then calls the specified exit program to take the desired action.
