Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

See the Veritas File System Administrator's
Guide.
Determine the number and sizes of file
systems you need for the database you want
to create.
■ See “About selecting a volume layout”
on page 51.
■ See “Creating a volume ” on page 53.
■ See “About tuning VxVM ” on page 299.
Create volumes to meet your file system
needs. You can use disk mirroring as a
safeguard against disk failures and striping
for better performance.
See “Hosts and storage for Database
FlashSnap ” on page 229.
If you plan to create volume snapshots for
the database and use them on either the
same host or a secondary one, ensure that
your volume layout is consistent with
Database FlashSnap requirements.
See “File system creation guidelines”
on page 55.
See “Creating a VxFS file system ”
on page 56.
Create the VxFS file systems you need on the
volumes.
See “About Quick I/O” on page 75.Install and configure your database.
For best OLTP performance, use Oracle Disk
Manager (ODM) or Quick I/O.
You must create Quick I/O files before
creating the tablespaces.
See “About Storage Mapping ” on page 133.If you would like the ability to view detailed
storage stack topology information to ensure
your storage stack configuration is optimized
for the database, configure and use Storage
Mapping.
See the Veritas Volume Manager
Administrator's Guide.
If you want to use Database FlashSnap for
off-host processing after converting your
database files to use Quick I/O or ODM and
your volume layout is inconsistent with
Database FlashSnap requirements, you will
need to “relayout” your volume manager
configuration after your database files have
been converted.
See “Converting Oracle files to Quick I/O
files” on page 84.
If you are using Quick I/O, convert all
database files to Quick I/O files.
See “Setting up Veritas Extension for Oracle
Disk Manager” on page 125.
If using ODM, link the ODM library.
