Use the prctl command to make runtime interrogations of and modifications to the resource
controls associated with an active process, task, or project on the system. See the prctl(1) man
page for more information.
# prctl $$ - displays all resource control values for given process.
# prctl -n process.max-file-descriptor $$ - more concrete
# prctl -n project.max-lwps -t privileged -v 3 -e deny -i project x-files - Add a new privileged value for project.max-lwps that limits the number of LWPs to three.
# prctl -n project.max-lwps -i project x-files - verifies previous.
# prctl -n process.max-file-descriptor -r -v 128 $$ - change the lowest value of the process.max-file-descriptor resource control.
Use the rctladm command to make runtime interrogations of and modifications to the global
state of the resource controls facility. See the rctladm(1M) man page for more information.
# rctladm -e syslog process.max-file-descriptor - enable the global syslog attribute of process.max-file-descriptor
# rctladm - displays the global flags, including the global type flag, for each resource control.
# ipcs - displays information regarding open IPCS
# ipcs -J - displays information regarding open IPCS (Project oriented)

- Observe whether the workload trips the resource control:
If it does, you will see /var/adm/messages such as:

Rlimits and resource controls.
UNIX systems have traditionally provided a resource limit facility (rlimit,plimit,ulimit).
The resource controls facility provides compatibility interfaces for the resource limits facility.
Existing applications that use resource limits continue to run unchanged.
