Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

Because the Database Dynamic Storage Tiering commands retrieve database
information from the repository, the repository must be up to date.
■ 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.
■ Create the volumes that you want to add to the multi-volume file system in
the same disk group as the file system volume. As root, use the following
command to change the owner of each volume:
# /opt/VRTS/bin/vxedit -g disk_group \
set user=oracle volume
■ Change the owner of the mount point on which you want to implement Database
Dynamic Storage Tiering to oracle.
Defining database parameters
Running the dbdst_admin command defines parameters for the entire database.
You must run this command at least once to define the database parameters for
Database Dynamic Storage Tiering. Three pre-defined storage classes will be
created (PRIMARY, SECONDARY, and BALANCE). Parameter values are stored in
the SFDB repository.
Set at least one of the parameters in maxclass, minclass, statinterval,
sweeptime, sweepinterval, purgetime, or purgeinterval, to enable default values.
Add at least one class to enable the default classes.
Table A-11 lists the options for the dbdst_admin command.
