Some interesting facts about Oracle Solaris 11.4
Before introducing the update, we might as well get to know the interesting periphery of Solaris 11.4. Officials say 175 development releases were made for Oracle Solaris 11.4 GA before it was released.Over 30 million hours running time (machine hour) test. In addition, more than 50 customers have used Oracle Solaris 11.4 in production environments, and more than 3,000 applications have been validated on it.Function.
Oracle Solaris 11.4 It is the first and the only operating system that has completed the UNIX V7 certification.
Next we may as well take a look at what are the noteworthy updates of this major version.
Noteworthy updates
Consistent compatibility
According to Oracle, they have guaranteed that Oracle Solaris can run applications built on older versions for nearly 20 years and will continue to do so today. In addition, they have done a lot of work, such as enhancing migration tools and documents to facilitate users.Easier migration of Oracle Solaris 10 workloads to Oracle Solaris 11 and easier migration from Oracle Solaris 10 to Oracle Solaris on modern hardware11.
Simple and easy to use
Oracle Solaris 11.4 Several new functions are added to make management easier. Among these new features is the new Observability Tools System Web Interface.
The Web interface integrates several key observability technologies, including new StatsStore data, audit events, and FMA events, into a centralized, customizable browser-based interface that allows users to see current and past system behavior at a glance. WhenHowever, you can add the data you want to collect and customize the interface according to your needs. If you want to export data to other applications, such as spreadsheets or databases, here’s a blog about how to import data into a CSV file. For more information about it, please visit ObservAbility Tools document for reading.
It also enhances the functionality of the Service Management Framework, allowing you to automatically monitor and restart critical applications and services. Click here to see how to use the new SMF goal services.
Starting with Oracle Solaris 11.4, users can build intra-Zone dependencies and start dependent zones in the right order, enabling users to start automatically in the right order.And restart the complex application stack. Related links (operation instructions, technical details).
Finally, a potentially popular feature in Oracle Solaris 11.4 is also provided, primarily for managing ZFS — deleting ZFS devices. Officials say this will make ZFS management simpler than it is now.
Enhanced security function
More security features are provided in Oracle Solaris 11.4 to make it easy to acquire and maintain security and compatibility.
Multi-node compliance: In Oracle Solaris 11.4, you can now set up compliance to push compliance evaluation across all systems with a single command and view it in a single reportAs a result, you can either set up the system to generate compliance reports periodically and push them to the central server, or you can view them from a single report. This makes it easier to maintain compliance with the entire data center. For details, check this.
Oracle Solaris Zones，Immutable Zones in particular are very useful tools for building isolation in your environment to protect applications and data centers from network attacks and even management errors. But sometimes there are too many areas. We just want to be able to isolate the system, orApplication in area or VM. To this end, Oracle Solaris 11.4 provides an application sandbox, which allows us to isolate applications. Sandbox provides additional application isolation and reduces the risk of unauthorized data access.
upgrade
In order to upgrade from Oracle Solaris 11.3 to Oracle Solaris 11.4 as smoothly as possible, a new compliance benchmark has been added that will tell you if it exists on Oracle Solaris 11.4In the old, unsupported device drivers and unsupported software or hardware problems.
To install this new benchmark, please update it to Oracle Solaris 11.3 SRU 35 and run:
# pkg install update-check
Then execute the check command.
# compliance assess -b ehc-update -a 114update# compliance report -a 114update -o ./114update.html
Finally, you can use FireFox to view reports.
