Any one know about HPUX Child Wrapper

amreek bansal — Mon, 06 Jul 2009 12:14:43 GMT

Hi,

Can someone shed some light on HPUX Child Wrapper? As we are having some performance issues on our databse server and I have noticed the process 'HPUXChildWrapper' process nearly consuming 90% of CPU.

Can any one explain what this process is ? and if its safe to kill it ? or restart ?

Thanks ...

Shalom,

Never heard of it.

UNIX95=1
export UNIX95
ps -ef -o pid,sz,vsz,args | grep -i child

Lets see the script or program that started it up.

I can't assess the danger without knowing what it is. Goggle gives me nothing.

It is part of the java environment. I don't know what exactly it does but you should look at the "ps" listing to see what java process is running under it.

Hi Guys, I poste dthis a while back, I seem to have this issue arising on my HPUX server again where the HPUX child Wrapper process is taking up nearly 90% of CPU. ANd recently we have had slow performace on the this databse server, so I am looking to get to the bottom of this HPUX Child Wrapper and understand if its okay to kill the process ? Will this cause any issues ? Can somone familar with this HPUX Child Srwapper process?

Thanks in Advance..

If this is really java stuff you should check for java patches instead: http://www.hp.com/go/java

Hi:

I would _NOT_ export the UNIX95 variable into your environment. This may have side effects for various commands that you are unaware of and might not be desirable.

_INSTEAD_ set the variable only for the duration of the command line like this:

# UNIX95= ps -ef -o pid,sz,vsz,args | grep -i child

Notice that there is no space after the "=" operator and no value needs to be set for 'UNIX95'. Its declaration alone is sufficient and this syntax sets it only for the duration of the command line --- a safe, sane approach.
