Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

of the StartVolumes and StopVolumes attributes are both 1, the DiskGroup agent
onlines and offlines the volumes during the import and deport operations of the
disk group. When using volume sets, set StartVolumes and StopVolumes attributes
of the DiskGroup resource that contains the volume set to 1. If a file system is
created on the volume set, use a Mount resource to mount the volume set.
The Mount agent brings online, takes offline, and monitors a file system or NFS
client mount point.
If you are using any of the Database Dynamic Storage Tiering commands in a high
availability (HA) environment, the time on each system in the cluster must be
synchronized. Otherwise, the scheduled task may not be executed at the expected
time after a service group failover.
For more information, see the Veritas Cluster Server Bundled Agents Reference
Guide.
Configuring Database Dynamic Storage Tiering
To use Database Dynamic Storage Tiering, you must:
■ Review Database Dynamic Storage Tiering command requirements.
■ Define database parameters.
■ Set up storage classes.
■ Convert an existing VxFS database file system to a VxFS multi-volume file
system for use with Database Dynamic Storage Tiering.
■ Classify, or tag, volumes so that the tags indicate the quality of the underlying
disk.
■ Display the free space on each class.
■ Add or remove volumes as necessary.
Database Dynamic Storage Tiering command requirements
Before defining your database parameters, review the following command
requirements:
■ An Oracle database must be up and running.
■ Only the Oracle database administrator can run Database Dynamic Storage
Tiering commands.
■ Run the dbed_update command before running any of the Database Dynamic
Storage Tiering commands. You should also run the dbed_update command
if any of the database files change.
