Servlet Engine/Web Container specific MustGather:

The following describes the steps to dynamically trace Servlet Engine/Web Container errors. You will be dynamically tracing AppServer using AppServer Ring Buffer tracing.

Assume the trace string will be the following:
com.ibm.servlet.engine.*=all=enabled

This trace can be set at the time the problem occurs by using the
following steps:

  1. Right click on appserver encountering the problem and select trace.
  2. Change the ring buffer size to "200". This equates to approximately an additional 40M Java™ heap usage. Be sure your AppServer mx value is set to accommodate the additional heap usage.
  3. Click Set Size.
  4. Expand components, com, ibm, servlet, engine (this will change depending on the required tracestring).
  5. Right click on engine and select all.
  6. Click on set.
  7. Recreate your problem.
  8. Go back to the trace screen, enter a "dump file name" into the field, and then click dump
  9. Send in the trace output file.
  10. Follow instructions tosend diagnostic information to IBM support.
