Managing boot environments in Solaris 11
Boot Environment (BE) A BE is a bootable instance of an Oracle Solaris 11 operating system plus any other application software packages installed into that image. System administrators can maintain multiple BEs on their systems, and each BE can have different software versions installed. With multiple BEs, the process of updating software becomes a low-risk operation because system administrators can create backup BEs before making any software updates to their system. If needed, they have … [Read more...] about Managing boot environments in Solaris 11

Oracle uses the Image Packaging System (IPS) to manage software updates. The Oracle Solaris 11 product engineering group releases software updates for the operating system on a regular basis. These updates are published as Support Repository Updates (SRUs) to a web-based Oracle repository and to My Oracle Support (MOS) for distribution. SRUs contains a number of bug fixes and critical security fixes that, when applied to an existing Oracle Solaris 11 systems, help to ensure that the systems run … [Read more...] about How to update Solaris 11 system Using IPS
Solaris 11 IPS pkg Command Examples
The Image Packaging System (IPS) is a framework that enables software lifecycle management, such as installation, upgrade and removal of packages. IPS also enables users to create their own software packages, create and manage package repositories, and copy and mirror existing package repositories. Packages can be installed only into file systems that are part of a boot environment (BE). For example, on a default Oracle Solaris 11 installation, only datasets under rpool/ROOT/BEname/ are … [Read more...] about Solaris 11 IPS pkg Command Examples

How To Auto Mount a FileSystem Using Systemd
Below example shows how to create a systemd script to mount a disk under a specific path on reboot automatically. 1. Check the filesystem UUID using the command "blkid". # blkid /dev/sdb /dev/sdb: UUID="5813cd72-ff30-44bc-a7a3-27c68fe3e6c7" UUID_SUB="ccd243dc-1481-403f-aa51-1502a95cdf2f" TYPE="btrfs" 2. We need to create a new mount unit to mount the filesystem. Mount units must be named after the mount point directories they control. For Example: the mount point /var/lib/docker must … [Read more...] about How To Auto Mount a FileSystem Using Systemd
