Admins,
We have an application that is using a lot of memory. The system is an RP5470 running HP-UX 11.0
I called application support and they emailed me back a list of their suggested kernel parameters.
Here is the email…
--------------------------------------------------------------
Dear Customer,
The following lists the parameter names and suggested values for these
parameters.
Name Suggested Value
nproc 532
max_thread_proc 256
maxfiles 4096
maxfiles_lim 4096
maxuprc 512
nfile 4096
nflocks 2048
ninode 2048
semmap 258
semmni 256
semmns 1024
semmnu 512
semume 256
maxDsiz Real + Virtual Memory
maxTsiz Real + Virtual Memory
maxSsiz 12% of (Real + Virtual Memory)
Resetting the values of these parameters requires a rebuild of HP-UX and a
system reboot. This takes the system off line for a short period of time.
Warn all users to log off first!
Regards,
Support
--------------------------------------------------------------------------
So I am going to go ahead and make all these changes….
For most of them I can just put in the number, but when I get to maxDsiz, maxTsiz, and maxSsiz I think I will have to put in their hex value???
Can I use a formula here? If yes what would it be?
We have 2GB of RAM and a swap partition of 2GB. So they are saying to use 4GB for the first two and 12% of 4GB for the last one. Does this exceed the max allowed???
In hex 4GB is EE6B2800 so would it be entered 0xEE6B2800??? What is the 0x for???
TIA and I summarize.
Tom
