List of Solaris commands for process management
Commands
apptrace – for tracing library calls
dtrace – debugger, new in version 10
pargs – get list of arguments and environment variables with which process was started
pfiles – list of file descriptors, associated with process
pgrep – get the PID's of processes by name i.e. Something like ps -efl|grep -v grep|grep process_name
pkill – send signal to process. For example pkill -9 init :-P
pldd – list dynamic libraries, associated with process, similar to ldd for executable
plockstat – see list of locked by process files. Lock can be mutex i.e. exclusive and reader/writer for shared access
pmap – get memory map (segments) of process
preap – try to kick-off zombie process
prstat – fullscreen view of processes sorted by different criteria, similar to Linux top command
prun – continue hold with pstop process
ps - print process information and status. In Solaris exist SYSV and BSD variants, respectively /usr/bin/ps and /usr/ucb/ps
psig – list signals that can be handled by process
pstack – get backtrace stack of process for debugging purposes
pstop – temporary hold process
ptree - print the tree of processes
pwait – wait till process finish
pwdx – list working directory for process, like pwd command
truss – for tracing user/library/system calls and signals

Examples
apptrace
# apptrace man

<- man -> libc.so.1:setlocale() = 0xd25002ed

<- man -> libc.so.1:fprintf() = 0x88
-> man -> libc.so.1:exit(0x2, 0x8047e30, 0x8047da0) ** NR
in the above example you can clearly see library calls as fprintf(), strcmp(), getenv(), etc.
pargs
# pargs 558 558: /usr/lib/sendmail -Ac -q15m argv[0]: sendmail: Queue runner@00:15:00 for /var/spool/clientmqueue argv[1]: <NULL> argv[2]: @00:15:00 for /var/spool/clientmqueue
in above example you see the arguments for starting sendmail as a daemon
pfiles
# pfiles 558
558: /usr/lib/sendmail -Ac -q15m

/var/spool/clientmqueue/sm-client.pid
Here you see a list of files as NULL, console log, some PID files. On the top you can see the maximum number of file handlers for this process, with info that can be helpful for troubleshooting of applications
pgrep
# pgrep named 586
Something like ps -efl|grep -v grep|grep process_name|awk '{print $1}'
# ps -e|grep -v grep|grep named|awk '{print $1}'
586
pkill
# pgrep named 628 # pkill named # pgrep named 636 #
As you see, the named daemon was killed and respawned (with new PID)
pldd
# pldd 636

This command helps in the process of fine-tuning large applications, especially for resolving emory leak issues
preap
# ps -efl|grep 551 0 Z root 551 550 0 0 - - 0 - - ? 0:00 <defunct> # preap 551 551: exited with status 0 # ps -efl|grep 551
In above example, this tool successfully removes zombie process. Otherwise the only way to kill them is to reboot

The program in default view is less informative that top, but can give you info for zones, projects and even for processes bind to specific processor. Use the -u option to limit display to specific users. Use the -p option to limit display to specific processes

This command can sometimes be very helpful for debugging daemons. You can see the function call stack by thread, in real-time
