Today, I will talk to you about the example analysis of memory leaks under AIX, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

The main purpose of memory leak is to monitor the memory consumption of the process. Under AIX, you can get the memory consumption through ps vg, so as to compare

In addition, there is a very useful script: post_vg.sh is used to compare memory increases

Here is an automatic script that used to monitor memory leaks

-

-- run_ps_vg.sh--

-

# crontab-e

# 10, home/root/run_vg.sh, 20, 30, 40, 50, 59, 9-20 * / home/root/postvg.trc

Fn=$1

Sysdate= `date`

Fname= "zzz * *" $sysdate

Echo $fname > > $fn

Ps vg > > $fn

-

-- analyze_post_vg.sh--

-

Fn=$1

Cat $fn | grep-n zzz | sed's / / _ / g' | sed's pedigree / / _ / g' | sed's Universe /'> tmp.out

While read hh rq

Do

Hh_list=$hh_list "" $hh

Rq_list=$rq_list "" $rq

Done vg_$ {rq_ array[i]}. Trc

Fi

Done

Ls-l | grep vg.*trc | awk'{print $9}'> tmp.out

While read trcfile

Do

Trcfile_list=$trcfile_list "" $trcfile

Done
