What answer includes three correct methods available to transition Oracle Solaris 10 environments to Oracle Solaris 11?
There are no upgrade methods or tools available to transition from Oracle Solaris 10 to Oracle Solaris 11. You cannot use an installer to upgrade from Oracle Solaris 10 to Oracle Solaris 11.
Oracle Solaris 11 Transition Tools and Features
/ JumpStart Migration Utility (js2ai)
Used to convert Oracle Solaris 10 JumpStart rules and profiles to a format that is compatible with AI manifest entries.
/ ZFS shadow migration feature
Used to migrate data from an existing file system to a new file system.
/ Oracle Solaris 11 support for Oracle Solaris 10 zones
Used to migrate your Oracle Solaris 10 application environments to an Oracle Solaris 11 system.
/ NFS file sharing and pool migration
Used to access shared files from an Oracle Solaris 10 system on an Oracle Solaris 11 system.
Used to import a ZFS storage pool from an Oracle Solaris 10 system into an Oracle Solaris 11 system.
Which command would you use, if running tools like vmstat and prstat is resulting in "file not found" errors?
To patch a Solaris system or install a command you use pkg command.
Assuming that a user called "operator" exists on the system and is configured to use a profile shell, what is the impact of the following sequence of commands?
The Stop rights profile is the simplest way to create a restricted shell. The authorizations and rights profiles that are assigned in the policy.conf file are not consulted. In the default configuration, the role or user is not assigned the Basic Solaris User rights profile, the Console User rights profile, or the solaris.device.cdrw authorization.
Example:
Assign the Desktop Applets rights profile and the Stop rights profile to the user.
# usermod -P 'Desktop Applets,Stop' username
This user does not have the Basic Solaris User rights profile or the Console User rights profile. Therefore, no commands other than the commands in the Desktop Applets rights profile can be run by this user.
Note:
* The usermod utility modifies a user's login definition on the system. It changes the definition of the specified login and makes the appropriate login-related system file and file system changes.
* Synopsis
usermod [-u uid [-o]] [-g group] [-G group [, group...]]
[-d dir [-m]] [-s shell] [-c comment] [-l new_name]
[-f inactive] [-e expire]
[-A authorization [, authorization]]
[-P profile [, profile]] [-R role [, role]]
[-K key=value] login
* -P profile
One or more comma-separated rights profiles defined in prof_attr.
* prof_attr
- profile description database
Three zones each need access to shared data. Which configuration method can be used to safely achieve this goal?
How to Loopback Mount a File That Is Usually Not Visible in a Labeled Zone
This procedure enables a user in a specified labeled zone to view files that are not exported from the global zone by default.
1. Halt the zone whose configuration you want to change.
# zoneadm -z zone-name halt
2. Loopback mount a file or directory.
For example, enable ordinary users to view a file in the /etc directory.
# zonecfg -z zone-name
add filesystem
set special=/etc/filename
set directory=/etc/filename
set type=lofs
add options [ro,nodevices,nosetuid]
end
exit
Note - Certain files are not used by the system, so that loopback mounting them has no effect. For example, the /etc/dfs/dfstab file in a labeled zone is not checked by Trusted Extensions software. For more information, see Sharing Files From a Labeled Zone.
3. Start the zone.
# zoneadm -z zone-name boot
Note:
* In this Solaris release, you create a ZFS file system share and publish the share as follows:
Create the file system share and define the NFS or SMB share properties by using the zfs share command.
* ZFS File Sharing Within a Non-Global Zone
In previous Solaris releases, you could not create and publish NFS or SMB shares in a Oracle Solaris non-global zone. In this Solaris release, you can create and publish NFS shares by using the zfs set share command and the legacy share command with a non-global zone.
* If a ZFS file system is mounted and available in a non-global zone, it can be shared in that zone.
* A file system can be shared in the global zone if it is not mounted in a non-global zone or is not shared to a non-global zone.
* If a ZFS file system's mountpoint property set to legacy, the file system can be shared by using the legacy share command.
What are the two reasons that network configurations are set using svccfg, ipadm, and nscfg?
E:
* Many configuration tasks around name services have moved into the SMF in Solaris 11.
* The Service Management Facility (SMF), first introduced in Oracle Solaris 10, is a feature of the operating system for managing system and application services, and it replaces the legacy init scripting start-up mechanism common to prior releases of Oracle Solaris and other UNIX operating systems. SMF improves the availability of a system by ensuring that essential system and application services run continuously even in the event of any hardware or software failures. SMF is one of the components of the wider Oracle Solaris Predictive Self Healing capability.
Note:
* In Oracle Solaris 11, certain aspects of system configuration have changed, including the migration of several system, network, and naming services configuration to SMF.
