Floware 6.1.4 kernel tuning

[Christopher E Chaves]

We're using Floware6.1.4 with Java 1.3. According to the Floware folks, HP's need the following kernel parameters changed:
nkthreads 30000 (max system limit)
max_thread_proc = 382 + (#floware clients *6) + 4
Has anyone made these changes? Anyone read anything about it?

Hi Christopher:

See here for some more information on 'nkthread' and the related kernel parameter 'max_thread_proc':

http://docs.hp.com/hpux/onlinedocs/os/KCparam.NkernelThreadsMax.html

Regards!

Hi,

Here is a good document on kernel threads
tuning.
Document Id : 2200094720
-------
The kernel parameter max_thread_proc limits the number of threads that a a single process can create; "nkthread" limits the combined total number of threads that can be
running on the system at any given time from all processes on thesystem. This value protects the system against being overwhelmed by alarge number of threads that exceeds normal, reasonable operation.
The nkthread parameter, or nproc,
may be increased depending on how heavily threads are used by an application.
*****
Since Floware is a hp product, i think you should be reasonably assured of the guidelines to increase this parameter. I haven't come across any application(so far) which recommends boosting this values, probably because they do not use threading extensively.
