Informatica Support recommends using the pmstack utility (https://communities.informatica.com/docs/DOC-7327) to generate the core stack trace and send it across to Informatica for further analysis.
It is difficult to come up with a general interpretation as the crash could be caused to a number of reasons which could involve sytems call, fucntions etc...
Generally stack trace files contain java exceptions since the core files are created by java processes. If you have java programming skills, you can do a fist hand analysis on the exceptions written on the trace files and then it is recommended to send the output to Informatica for the root cause analysis (RCA) since these files are reviewed by their product specialist team who has thorough knowledge on the tool functioning.
If your PowerCenter version is 9.x, you can use the utility Infa9Dump to generate the trace files. Please refer below link for more information on this utility:
Adding to Raman's post , got thru below KB addon information. Also with 9.x version you can install Infa9dump utility for tracing the corefiles.
Also you can upload these large corefiles for Informatica Global Customer Support engineers for further analysis. Below KB will help you in setting
web based interface for FTP large files.
Thanks All For the Update!! Yes we do all utilities set up for getting the trace files but was trying to understad if we any other interface available to interpret the core trace file to do the initial analysis before having enaged the Informatica Support team for the RCA..
A simple NO.
