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.
