Using Serviceguard Extension for RAC, 4th Edition, February 2007

Serviceguard Configuration for Oracle 10g RAC
Creating a Storage Infrastructure with LVM
Chapter 262
The size of the logical volume is larger than the Oracle file size because
Oracle needs extra space to allocate a header in addition to the file's
actual data capacity.
Create these files if you wish to build the demo database. The three
logical volumes at the bottom of the table are included as additional data
files, which you can create as needed, supplying the appropriate sizes. If
your naming conventions require, you can include the Oracle SID and/or
the database name to distinguish files for different instances and
different databases. If you are using the ORACLE_BASE directory
structure, create symbolic links to the ORACLE_BASE files from the
appropriate directory. Example:
# ln -s /dev/vg_ops/ropsctl1.ctl \
/u01/ORACLE/db001/ctrl01_1.ctl
After creating these files, set the owner to oracle and the group to dba
with a file mode of 660. The logical volumes are now available on the
primary node, and the raw logical volume names can now be used by the
Oracle DBA.
