4 Performing Database Validator
Operations
Starting Database Validator Operations
Database Validator operations are controlled through XP RAID Manager commands. No other program
product or application can be used. XP RAID Manager provides the raidvchkset, raidvchkdsp, and
raidvchkscan commands to set and verify the parameters for Oracle data validation checking at the
LU level. For detailed information on these commands, see the HP StorageWorks XP RAID Manager
User's Guide.
To start Database Validator operations, use the raidvchkset XP RAID Manager command to enable
Database Validator checking at the volume level for the desired LU(s). For LUs with multiple paths,
make sure to enable checking for all paths. Specify the type of check according to the Oracle version.
See “ Sample Implementation of Database Validator ” on page 19 for an example of configuring,
starting, and performing Database Validator operations.
Follow these restrictions:
• Validation must temporarily be turned off before changing LVM configuration. Initial configuration
of LVM should be completed before enabling validation.
• Validation must temporarily be turned off before restoring data from a backup which was taken
prior to enabling this function.
• The CREATE TABLESPACE command must be used with the REUSE option. Depending on the host
environment, a validation error may occur without the REUSE option.
• All programs other than the Oracle Database application should not write to validation target
volumes. Use caution when multiple paths are defined for one volume.
Note: Once the Database Validator checking function is enabled for an LU, all write operations to
that LU must have a valid Oracle checksum.
Sample Implementation of Database Validator
Figure 5 shows a sample Database Validator system configuration. This section presents the setup
and operational information for this sample configuration:
• Volume setup
• XP RAID Manager setup
• Oracle setup
• Enabling Database Validator checking
• Displaying Database Validator volumes
• Disabling and restarting Database Validator checking
Note: This section describes the setup operations for the Solaris and VxVM environment. These
operations can be easily translated to other platforms.
