System Dumps generation in AIX

Posted by madeeswer 2516 days ago (Editorial)

System dumps are taken to get a clear picture of systems utilization at that exact moment.


Normally system dumps are taken along with the java heap dump and thread dump for getting a clear picture about the system.


 


following are the steps to generate system dumps,


 


1.  Login  as root user


2. generate gencore file


     gencore /tmp/gencore.22_10


This will generate a .Z file


e.g. /tmp/gencore.22_10.Z


3. uncompress the file


uncompress /tmp/gencore.22_10.Z


4. use jextract to zip the file


/java/jre/bin/jextract /tmp/gencore.22_10


 


Note: Jextract will be there in jre/bin location.
