Example: Displaying Information About the System Administrator Rights Profile

Use the profiles command to display information about a specific rights profile. In the following example, information about the System Administrator rights profile is displayed:

$ profiles -p "System Administrator" info

name=System Administrator

desc=Can perform most non-security administrative tasks

profiles=Install Service Management,Audit Review,Extended Accounting Flow

Etc.

The FX scheduler provides a scheduling policy for processes that require user or application control of scheduling priorities. The priorities of processes that run under FX are fixed.

The FX class provides a fixed-priority preemptive scheduling policy. This policy is used by processes that require user or application control of scheduling priorities but are not dynamically adjusted by the system. By default, the FX class has the same priority range as the TS, IA, and FSS classes. The FX class allows user or application control of scheduling priorities through user priority values assigned to processes within the class. These user priority values determine the scheduling priority of a fixed-priority process relative to other processes within its class.

Incorrect:

Not A: The fair share scheduling class enables you to allocate CPU time based on shares instead of the priority scheme of the timesharing (TS) scheduling class.

Not D: The goal of the time-sharing policy is to provide good response time to interactive processes and good throughput to CPU-bound processes. The scheduler switches CPU allocation often enough to provide good response time, but not so often that the system spends too much time on switching. Time slices are typically a few hundred milliseconds.

The time-sharing policy changes priorities dynamically and assigns time slices of different lengths.

Install services are created with a default AI manifest, but customized manifests or derived manifests scripts (hereafter called “scripts”) can be added to an install service by using the create-manifest subcommand.

* Example:

Add the new AI manifest to the appropriate AI install service, specifying criteria that define which clients should use these installation instructions.

# installadm create-manifest -n s11-x86 -f ./mem1.xml -m mem1 \

-c mem="2048-unbounded"

* Syntax

installadm create-manifest -n|--service svcname

-f|--file manifest_or_script_filename

[-m|--manifest manifest_name]

[-c|--criteria criteria=value|list|range... |

-C|--criteria-file criteriafile]

[-d|--default]

Scheduling classes provide different CPU access characteristics to threads that are based on algorithmic logic. The scheduling classes include:

Realtime scheduling class (RT) (not a)

Interactive scheduling class (IA)

Fixed priority scheduling class (FX) (not b)

Timesharing scheduling class (TS) (not c)

Fair share scheduling class (FSS) (not E)
