data. If required, you can offload processing of the point-in-time copies onto
another host to avoid contention for system resources on your production server.
For instructions on creating snapshots for offhost processing, see the Veritas
Storage Foundation: Storage and Availability Management for Oracle Databases
guide.
Managing database storage efficiently using SmartTier
SmartTier matches data storage with data usage requirements. After data
matching, the data can be relocated based upon data usage and other requirements
determined by the storage or database administrator (DBA). The technology
enables the database administrator to manage data so that less frequently used
data can be moved to slower, less expensive disks. This also permits the frequently
accessed data to be stored on faster disks for quicker retrieval.
For instructions on managing database storage efficiently using SmartTier, see
the Veritas Storage Foundation: Storage and Availability Management for Oracle
Databases guide.
Optimizing database storage using Thin Provisioning and SmartMove
Thin Provisioning is a storage array feature that optimizes storage use by
automating storage provisioning. With Storage Foundation’s SmartMove feature,
Veritas File System (VxFS) lets Veritas Volume Manager (VxVM) know which
blocks have data. VxVM, which is the copy engine for migration, copies only the
used blocks and avoids the empty spaces, thus optimizing thin storage utilization.
For instructions on managing database storage efficiently using Thin Provisioning
and SmartMove, see the Veritas Storage Foundation Advanced Features
Administrator's Guide.
Scheduling periodic health checks for your cluster
You can manually invoke the health check utility at any time or schedule the
utility to run as a cron job.
If the health check completes without any warnings, the following message is
displayed:
Success: The SF Oracle RAC components are working fine on this node.
If you manually invoke the health check, run the utility on each node in the cluster.
The results of the check are displayed on the console.
Log in as the root user on each node in the cluster and run the following commands:
