Re: HP UX java program use 100% cpu
Hi ,
what do those jar do , those you moved ?
1)check if you are up to date on patches :
hpjconfig , as per you server model.
http://docs.hp.com/en/5992-4687/ch01s06.html.
2)kill -3 to the java process , do a heap and dump anlysis .you can download the heasp and dump analyser frorm IBM site.this will let you know if you have waiting threads and the reason for the same.

Re: HP UX java program use 100% cpu
download hpjmeter (do a search at software.hp.com) for it. Install it and start using to to analyse your java programs
