Add a memory cap.

zonecfg:my-zone> add capped-memory

Set the memory cap.

zonecfg:my-zone:capped-memory> set physical=50m

End the memory cap specification.

zonecfg:my-zone:capped-memory> end

Pgrep takes a process name and return a PID.

Note: pgrep looks through the currently running processes and lists the process IDs which matches the selection criteria to stdout. All the criteria have to match. For example, pgrep -u root sshd will only list the processes called sshd AND owned by root.

Incorrec answers:

ps bigscript: You can’t pass a name to ps, it interprets it as arguments.

On POSIX-compliant platforms, SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.

SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process, but unlike the SIGKILL signal, it can be caught and interpreted (or ignored) by the process. Therefore, SIGTERM is akin to asking a process to terminate nicely, allowing cleanup and closure of files. For this reason, on many Unix systems during shutdown, init issues SIGTERM to all processes that are not essential to powering off, waits a few seconds, and then issues SIGKILL to forcibly terminate any such processes that remain.

Note 1: State Transition Sets are defined as:

to

Set of all transitions that have as the final state of the transition.

form-

Set of all transitions that have as the initial state of the transition.

Set of all transitions that have as the initial state of the transitional.

Set of all transitions. (A)

Valid values of state are maintenance, offline (G), disabled (E), online and degraded. An example of a transitions set definition: maintenance, from-online, to-degraded.

F: In this context, events is a comma separated list of SMF state transition sets or a comma separated list of FMA (Fault Management Architecture) event classes. events cannot have a mix of SMF state transition sets and FMA event classes. For convenience, the tags problem- {diagnosed, updated, repaired, resolved} describe the lifecycle of a problem diagnosed by the FMA subsystem - from initial diagnosis to interim updates and finally problem closure.

Note 2:

SMF allows notification by using SNMP or SMTP of state transitions. It publishes Information Events for state transitions which are consumed by notification daemons like snmp-notify(1M) and smtp-notify(1M). SMF state transitions of disabled services do not generate notifications unless the final state for the transition is disabled and there exist notification parameters for that transition. Notification is not be generated for transitions that have the same initial and final state.
