Examine the output of the following commands:
Which statement is true concerning these resource controls settings?
A.
The zone.max-lwps resource control was set to its value when the zone.max-processes
resource control was set to its value.
B.
The prctl command can be used to change the max value for these resource controls.
C.
The zone.max-processes resource control will deny zombie processes from exhausting the
resource table.
D.
The zone.max-lwps resource control will deny zombie processes from exhausting the process
table.
Explanation:
* zone.max-processes
Maximum number of process table slots
simultaneously available to this zone.
Because both normal processes and
zombie processes take up process table
slots, the max-processes control thus
protects against zombies exhausting the
process table. Because zombie processes
do not have any LWPs by definition, the
max-lwps control cannot protect against
this possibility
Note:
* prctl – operations on a process
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.
