Your Path to Success: How to Pass the Oracle 1z0-822 Oracle Solaris 11 Advanced System Administration Exam

An interface that has been created cannot become a member of an aggregation.

* 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.

* pkg.depotd is the depot server for the image packaging system. It provides network access to the data contained within a package repository. Clients that do not support direct access to a repository through the file system, or for which network access is the only available or preferred method of transport, typically use the package depot.

* Example:

Configure pkg.depotd to provide remote access. pkg.depotd provides an HTTP interface to a pkg repo. Here we are going to make the repo server listen on port 10000, and use the repo dir we created as its default.

# svcadm disable pkg/server

# svccfg -s pkg/server setprop pkg/inst_root = /data/myrepo

# svccfg -s pkg/server setprop pkg/port = 10000

# svcadm refresh pkg/server

# svcadm enable pkg/server

Network drivers that support link-based failure detection monitor the interface's link state and notify the networking subsystem when that link state changes.

Incorrect:

Not B: GLDv2 is a multi-threaded, clonable, loadable kernel module that provides support to device drivers for local area networks. Local area network (LAN) device drivers in the Solaris OS are STREAMS-based drivers that use the Data Link Provider Interface (DLPI) to communicate with network protocol stacks.

Not D: Link-based failure detection is always enabled, provided that the interface supports this type of failure detection.

You cannot disable link-based failure detection if this method is supported by the NIC driver.

Note:

* To write a network driver for the Oracle Solaris OS, use the Solaris Generic LAN Driver (GLD) framework.

/ For new Ethernet drivers, use the GLDv3 framework.

/ To maintain older Ethernet, Token Ring, or FDDI drivers, use the GLDv2 framework.

* To ensure continuous availability of the network to send or receive traffic, IPMP performs failure detection on the IPMP group's underlying IP interfaces. Failed interfaces remain unusable until they are repaired. Remaining active interfaces continue to function while any existing standby interfaces are deployed as needed.

The in.mpathd daemon handles the following types of failure detection:

/ Probe-based failure detection, of two types:

No test addresses are configured (transitive probing).

Test addresses are configured.

/ Link-based failure detection, if supported by the NIC driver

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]

zonecfg subcommand info:

info zonename | zonepath | autoboot | brand | pool | limitpriv

info [resource-type [property-name=property-value]*]

Display information about the current configuration. If resource-type is specified, displays only information about resources of the relevant type. If any property-name value pairs are specified, displays only information about resources meeting the given criteria. In the resource scope, any arguments are ignored, and info displays information about the resource which is currently being added or modified.

Incorrect:

Not A: priocntl- process scheduler control

The priocntl() function provides for control over the scheduling of an active light weight process (LWP).

Not C: rctladm- display and/or modify global state of system resource controls.

The rctladm command allows the examination and modification of active resource controls on the running system.

Not D: prctl

- get or set the resource controls of running processes, tasks, and projects

The prctl utility 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 on the specified entity.

Gathering Statistics About Network Traffic on Flows

Flow statistics help you evaluate packet traffic on any defined flows on the system. To obtain flow information, you use the flowstat command.

* Display statistics about incoming and outgoing packets on all flows.

# flowstat

This command provides a static display of traffic information on all configured flows.

Incorrect:

Not A: In computing, sar (System Activity Report) is a Solaris-derived system monitor command used to report on various system loads, including CPU activity, memory/paging, device load, network.
