Hitachi Database Validator

The Database Validator feature is designed for the Oracle
data corruption between the database and the storage system. Database Validator prevents
corrupted data blocks generated in the database-to-storage system infrastructure from being
written onto the storage disk. The combination of networked storage and database
management software has a risk of data corruption while writing data on the storage. This
data corruption rarely occurs; however, once corrupted data is written into storage, it can
be difficult and time-consuming to detect the underlying cause, restore the system, and
recover the database. Database Validator helps prevent corrupted data environments and
minimizes risk and potential costs in backup, restore, and recovery operations. Database
Validator combined with the Oracle9i Database product provides a resilient system that can
operate for 24 hours a day, 365 days a year to provide the uptime required by enterprises
today.
The Hitachi RAID storage systems support parameters for validation checking at the volume
level, and these parameters are set through the command device using the Command
Control Interface (CCI) software. CCI supports commands to set and verify these parameters
for validation checking. Once validation checking is turned on, all write operations to the
specified volume must have valid Oracle checksums. CCI reports a validation check error to
the syslog file each time an error is detected.
Database Validator requires the CCI software product and a separate license key. Database
Validator is not controlled via the Storage Navigator remote console software.
For details on Database Validator operations, please see the Database Validator Reference
Guide for the storage system (e.g., Hitachi TagmaStore
Guide), or contact your Hitachi Data Systems account team.
