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
