Description

Resolution:
There are NO predefined values required as such for the Kernel parameters on HP-UX for IM.
However, in general for Java applications, following are the recommendations -
maxdsiz: 256MB
Threads per process: 256
The general rule for swap space is that it should be double the amount of RAM installed on your system.

Also following are the thread parameters you need to check on your HP-UX machine -
1) max_thread_proc - The maximum number of threads allowed in each process. The minimum value (and default) is 64, often too low for most Java applications. The maximum value is the value of nkthread.

2) nkthread - The total number of kernel threads available in the system. This parameter is similar to the nproc tunable except that it defines the limit for the total number of kernel threads able to run simultaneously in the system. The value must be greater than nproc. The default is approximately twice that of nproc. The maximum is 30000. The suggested value of nkthread is 2*max_thread_proc. If you have many Java processes running and each running process uses many threads, you will want to increase this value.
