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.
Displaying the Logical Volume Infrastructure
To display the volume group, use the vgdisplay command:
# vgdisplay -v /dev/vg_ops
Exporting the Logical Volume Infrastructure
Before the Oracle volume groups can be shared, their configuration data must be
exported to other nodes in the cluster. This is done either in Serviceguard Manager or
by using HP-UX commands, as shown in the following sections.
