HP-UX: Threads per process

is there a command on HP-UX to check and view all the threads related to a 开发者_运维知识库process/task.

ps -m isn't supported.

You can display a stack trace of the threads belonging to a particular process using pstack. It will also give you the LWPID (thread ID). For example:

$ whereis pstack
pstack: /usr/ccs/bin/pstack /usr/share/man/man1.Z/pstack.1

$ ps -ef|grep snmpAgt|grep -v grep

$ pstack 27447|head -30
