Veritas extension for Oracle Disk Manager

Veritas extension for Oracle Disk Manager

The Veritas extension for Oracle Disk Manager (ODM) is specifically designed for Oracle9i or later to enhance file management and disk I/O throughput. The features of Oracle Disk Manager are best suited for databases that reside in a file system contained in Veritas File System. Oracle Disk Manager allows Oracle9i or later users to improve database throughput for I/O intensive workloads with special I/O optimization.
The Veritas extension for Oracle Disk Manager is supported in non-global zones. To run Oracle 10g on a non-global zone and use Oracle Disk Manager, the Oracle software version must be 10.1.0.3 or higher.
The following procedure enables Oracle Disk Manager file access from non-global zones with Veritas File System.
To enable Oracle Disk Manager file access from non-global zones with Veritas File System
  1. Make global zone licenses visible to the non-global zone by exporting the /etc/vx/licenses/lic directory to the non-global zone as a lofs:
      global# zonecfg -z myzone
  zonecfg:myzone> add fs
  zonecfg:myzone:fs> set dir=/etc/vx/licenses/lic
  zonecfg:myzone:fs> set special=/etc/vx/licenses/lic
  zonecfg:myzone:fs> set type=lofs
  zonecfg:myzone:fs> end
  zonecfg:myzone> commit
  2. Create the /dev/odm directory in the non-global zone from the global zone:
    global# mkdir -p myzone/dev/odm
  3. Log in to the non-global zone and mount /dev/odm, or run S92odm start:
      global# zlogin myzone
  myzone# mount -F odm /dev/odm /dev/odm
    Or:
      global# /etc/rc2.d/S92odm start
    /dev/odm is not automatically mounted after a zone is booted. Use the S92odm start command to mount /dev/odm after a zone is booted.

BMCs and the IPMI Protocol

Image
Baseboard Management Controllers (BMCs) are a type of embedded computer used to provide out-of-band monitoring for desktops and servers. These products are sold under many brand names, including HP iLO, Dell DRAC, Sun ILOM, Fujitsu iRMC, IBM IMM, and Supermicro IPMI. BMCs are often implemented as embedded ARM systems, running Linux and connected directly to the southbridge of the host system's motherboard. Network access is obtained either via 'sideband' access to an existing network card or through a dedicated interface. In addition to being built-in to various motherboards, BMCs are also sold as pluggable modules and PCI cards. Nearly all servers and workstations ship with or support some form of BMC. The Intelligent Platform Management Interface (IPMI) is a collection of specifications that define communication protocols for talking both across a local bus as well as the network. This specification is managed by Intel and currently comes in two flavors, ve...

Understanding How ZFS Calculates Used Space

This document explains how ZFS calculates the amount of used space within a zpool and provides examples of how various ZFS features affect that calculation. DETAILS A ZFS storage pool is a logical collection of devices that provide space for datasets such as filesystems, snapshots and volumes. A zfs pool can be used as a filesystem, i.e. such as mounting/unmounting; to take snapshots that provides read-only (clones are writable copies of snapshots) copies of the filesystem taken in the past; to create volumes that can be accessed as a raw and a block device and for setting properties on datasets. Interaction of all these datasets and associated properties such as quotas, reservations, compression and deduplication (Solaris 11 only) play a role in how ZFS calculates space usage. Neither the du nor df command have been updated to account for ZFS file system space usage. When calculating zfs space usage, always use the following command. # zfs list -r -o space <pool_name...
