30 Nov 2014 Oracle Solaris 11 - Beginners Guide [39497]
From UnixArena

Lingeswaran writes, "If you are working as a Sun Solaris system administrator, you know that how rapidly Solaris operating system is changing from version to version. There were a lot difference between Solaris 9 and Solaris 10. But people were able to grab the changes quickly in the past when it was transformed from Solaris 8/9 to Solaris 10. ZFS and Zones were not utilized potentially on Solaris 10 and this could be the reason why the system administrators couldn't find any difficulties. But now most of the people are asking that how and where to start for oracle Solaris 11..."

31 Oct 2014 Hard Partitioning With Oracle Solaris Zones [39050]
An Oracle White Paper - Oct 2014

This document describes hard partitioning with Oracle Solaris Zones (also known as Oracle Solaris Containers), and how to use it to conform to the Oracle licensing policies for partitioned environments.

The approved hard partition configurations described below apply to all types of Oracle Solaris Zones, which include but are not limited to Native Zones, Kernel Zones, Oracle Solaris Legacy Containers and, Oracle Solaris 10 Zones on Oracle Solaris 11.

NOTE: the Oracle licensing document referenced above states that the acceptable way to configure Oracle Solaris Zones is using 'capped Zones/Containers only'. The use of the designation 'capped' is a generic way of stating the Oracle Solaris Zone has a defined upper CPU boundary which is less than all the CPUs on the system. In this instance the term 'capped' refers to all valid methods of configuring Oracle Solaris Zones as hard partitions. It should not be specifically associated with the capped-cpu setting used by the zonecfg command.

31 Oct 2014 How to Configure a Failover Oracle Solaris Kernel Zone [39046]
by Venkat Chennuru

This article describes how to configure an Oracle Solaris Kernel Zone in failover mode in a two-node cluster using the Oracle Solaris Cluster high availability (HA) agent for Oracle Solaris Zones.

This article is intended to help a new or experienced Oracle Solaris administrator to quickly and easily configure an Oracle Solaris Kernel Zone in failover mode using the Oracle Solaris Cluster HA for Oracle Solaris Zones agent. For more details, see the Oracle Solaris Cluster Data Service for Oracle Solaris Zones Guide.

About Oracle Solaris Cluster Failover Zones

Oracle Solaris Zones include support for fully independent and isolated environments called kernel zones, which provide a full kernel and user environment within a zone. Kernel zones increase operational flexibility and are ideal for multi-tenant environments where maintenance windows are significantly harder to schedule. Kernel zones can run at a different kernel version from the global zone and can be updated separately without requiring a reboot of the global zone. You can also use kernel zones in combination with Oracle VM Sever for SPARC for greater virtualization flexibility.

This article describes how to set up a failover kernel zone on a two-node cluster.

09 Oct 2014 How-To: Lifecycle Management for Zones [38724]
By Owen Allen

Owen writes, "Oracle Solaris Zones are a useful too. As I've been discussing over the past few weeks, Ops Center lets you manage zones from a high level by creating them, grouping them into server pools, and migrating them. However, I haven't talked about how to use Ops Center for more day-to-day zone management.

When a zone is managed in Ops Center, you can see its current state - running, shut down, or unreachable - in the Assets section, shown by an icon over the asset. By selecting a specific zone, you can take a number of possible actions: you can reboot or shut down a running zone, halt a zone if it's not responding to a graceful shutdown, boot a stopped zone, or delete a zone if it's no longer needed..."

25 Sep 2014 Creating a Server Pool for Oracle Solaris 11 Zones [38466]
Big advantages to pooling your zones

Owen Allen writes, "I talked a bit last week about creating Oracle Solaris 11 zones by following the zone creation how-to. If you're creating zones on at least two systems, it's a good idea to create a server pool for them. A zones server pool lets you group 2 or more global zones (hosts) that have the same processor architecture. The hosts must share storage resources and have access to the same virtual and physical networks..."
