AIX problem determination

This section describes problem determination on AIX®.

Setting up and checking your environment on AIX
Set up the correct environment for the AIX Java™ virtual machine (VM) to run correctly during AIX installation from either the installp image or the product with which it is packaged.
General debugging techniques
A short guide to the diagnostic tools provided by the JVM and the AIX commands that can be useful when diagnosing problems with the AIX JVM.
Diagnosing crashes
If a crash occurs, you should gather some basic documents. These documents either point to the problem that is in the application or vendor package JNI code, or help the IBM® VM Support team to diagnose the fault.
Debugging hangs
The JVM is hanging if the process is still present but is not responding in some sense.
Understanding memory usage
Before you can properly diagnose memory problems on AIX, first you must have an understanding of the AIX virtual memory model and how the JVM interacts with it.
Debugging performance problems on AIX
Locating the causes of poor performance is often difficult. Although many factors can affect performance, the overall effect is generally perceived as poor response time or slow execution of your program.
MustGather information for AIX
The information that is most useful at a point of failure depends, in general, on the type of failure that is experienced.
