max_thread_proc value on HP-UX 11.11

max_thread_proc value on HP-UX 11.11

Is the kernel tunable on HP-UX max_thread_proc configurable to a higher value than the default?

What is the recommended value for max_thread_proc on HP-UX 11.11?

How much should this value (recommended) be set to if a java application is running on HP-UX 11.11?

How do we determine a safe value that can be set to max_thread_proc kernel tunable on HP-UX 11.11?

Naturally, otherwise the default would be the color black. ;-)

>What is the recommended value for max_thread_proc on HP-UX 11.11?

It depends on the application mix. Are you running into errors trying to create threads with the default of 256?

>How much should this value (recommended) be set to if a java application is running on HP-UX 11.11?

It depends on your java application.

Your programs won't abort if it is large enough. And your applications don't slow down because they are thread crazy.

Shalom,

Java is notoriously process and resource hungry.

Where to set levels can only be done by looking at use levels.

Glance gpm high water mark display is a good way to know when you need to increase things.

parameters to watch:
nproc
maxuprc # max process to a single user.

For patching and resource needs for a java server see: http://www.hp.com/go/java

Hi,
>>Is the kernel tunable on HP-UX max_thread_proc configurable to a higher value than the default?

Ofcource you can change the default value.

>>How much should this value (recommended) be set to if a java application is running on HP-UX 11.11?

Its better to ask application owner or any java guru.
