Oracle 1Z0-821 Dumps - Pass Solaris 11 System Administration Exam in 2026

Theprctlutility allows the examination and modification of the resource controls associated with an active process, task, or project on the system. It allows access to the basic and privileged limits and the current usage on the specified entity.

How to Change thezone.cpu-sharesValue in a Zone Dynamically

This procedure can be used in the global zone or in a non-global zone.

For more information about roles, seeConfiguring and Using RBAC (Task Map) inSystem Administration Guide: Security Services.

# prctl -n zone.cpu-shares -r -v value -i zone zonename

idtypeis either thezonenameor thezoneid.valueis the new value.

Note: project.cpu-shares

Number of CPU shares granted to a project for use with the fair share scheduler

* The whoami utility displays your effective user ID as a name.

Here this would be root.

* who am i

The command who shows who is logged on.

Here this would be:

user1 console Dec 30 20:20

* The id utility displays the user and group names and numeric IDs, of the calling process, to the standard output. If the real and effective IDs are different, both are displayed, otherwise only the real ID is displayed.

Here this would be:

uid=0(root) gid=0(root)

Note:

Each UNIX proces has 3 UIDs associated to it. Superuser privilege is UID=0.

Real UID

--------

This is the UID of the user/process that created THIS process. It can be changed only if the running process has EUID=0.

Effective UID

-------------

This UID is used to evaluate privileges of the process to perform a particular action. EUID can be change either to RUID, or SUID if EUID!=0. If EUID=0, it can be changed to anything.

Saved UID

---------

If the binary image file, that was launched has a Set-UID bit on, SUID will be the UID of the owner of the file. Otherwise, SUID will be the RUID.

Audit Significant Events in Addition to Login/Logout (see step 2 below)

Use this procedure to audit administrative commands, attempts to invade the system, and other significant events as specified by your site security policy.

For all users and roles, add the AUE_PFEXEC audit event to their preselection mask.

# usermod -K audit_flags=lo, ps:no username

# rolemod -K audit_flags=lo, ps:no rolename

# auditconfig -setpolicy +argv

3- Record the environment in which audited commands are executed.

# auditconfig -setpolicy +arge

Note: [-t] -setpolicy [+|-]policy_flag[, policy_flag ...]

Set the kernel audit policy. A policy policy_flag is literal strings that denotes an audit policy. A prefix of + adds the policies specified to the current audit policies. A prefix of - removes the policies specified from the current audit policies. No policies can be set from a local zone unless the perzone policy is first set from the global zone.
