Hi there ,

 

     I went through many discusstion here but still cannot find how can this be done. Current value of ulimit -n is 2048

 

I need to change it to 65536 or unlimited as required on from Oracle .

 

 

    I'm not fully aware of HP-UX but know how change values and kernel parameter , if I can change it from /etc/profile 

what lines need to be added .

 

 

   Thanks ....

In order to increase "ulimit -n" you must use kctune(1m) to increase maxfiles_lim(5):

kctune maxfiles_lim=65535

Try using "ulimit -n", if that hasn't changed, you may have to login again.

No, this should be permanent.  Unless there is already something in /etc/profile or ~/.profile that changes it.
