How to analyze AIX Dumps


Analysing dump on AIX 6.1

First check if your system has produced the dump successfully
# sysdumpdev –L



You should see message as “dump completed successfully”

Then generate the snap with the command “snap –ac”

Once you have the snap completed, then move the snap to a directory where you have more free space to extract the snap.

Extract snap commands:
# uncompress snap.pax.Z
# pax -rvf snap.pax
# cd dump
# uncompress unix.Z
# dmpuncompress dump.BZ

To invoke the dump analysis run the below command in the same dir

# kdb dump unix


Read the perfpmr trace files

Search for the FMT file under the perfpmr directory and locate the path since you need to use it for analysis
