While working with Informatica PowerCenter, at times we come across scenarios where a session or process hangs. Sometimes process or session crashes and generates a core file. The pmstack utility is a Unix script file that retrieves the stack trace from a core file or hanging process and creates an output file that can be used for analysis and debugging. You  can also send it to Informatica support for further troubleshooting. Note:

• This tool requires that you have a debugger installed on your server as explained below
  • dbx on AIX.
  • gdb on Solaris, HP-UX & Linux.
• Contact your System Administrator if you are not certain about availability of the debugger on your PowerCenter server.
• Ensure that you use this tool with same user-id that started Informatica Services.

You can download this listing as part of the Debugging Tools bundle.
