Unless otherwise noted, features pertain to both the Standard and Enterprise Edition products.
Features
VERITAS Storage Foundation for Oracle combines the strengths of the core VERITAS technology products with database-specific enhancements to offer performance, availability, and manageability for Oracle database servers.
VERITAS Storage Foundation for Oracle includes the following products:
- VERITAS Volume Manager (VxVM)
A disk management subsystem that supports disk striping, disk mirroring, and simplified disk management for improved data availability and performance.
- VERITAS Database FlashSnap
Database FlashSnap, a feature of the Enterprise Edition, lets you create, resynchronize, and reverse resynchronize an online point-in-time image of a database. You can use this image to perform backup, other maintenance tasks, or off-host processing while providing continuous data availability. Also, database administrators can perform these tasks without root privileges. Database FlashSnap tasks may be performed through the VERITAS Storage Foundation for Oracle GUI or the command line interface.
- VERITAS Storage Mapping
Storage Mapping, a feature of the Enterprise Edition, lets you take full advantage of Oracle storage mapping to map datafiles to physical devices and display storage object I/O statistics. Oracle's file mapping (I/O topology) feature was introduced beginning with Oracle9i Release 2.
Both storage object I/O statistics and the storage structure can be displayed for a specific file using either the vxstorage_stats command or the VERITAS Storage Foundation for Oracle GUI. In addition, mapping information showing which tablespaces reside on which physical disks can be obtained for a specified database using the dbed_analyzer command.
- VERITAS Database FlashSnap
Database FlashSnap is a separately-licensed option available for purchase if you have the Enterprise Edition. Database FlashSnap lets you create and resynchronize volume snapshots for databases. The snapshots can be used on a second host. Also, database administrators can perform these tasks without root privileges.
- VERITAS Storage Mapping
Storage Mapping is a separately-licensed option available for purchase if you have the Enterprise Edition. Storage Mapping lets you take full advantage of Oracle storage mapping to map datafiles to physical devices. Oracle's mapping feature is only available with Oracle9i Release 2's File Mapping (I/O topology) feature.
- VERITAS File System (VxFS)
A high-performance, fast-recovery file system that is optimized for business-critical database applications and data-intensive workloads. VxFS offers online administration, letting you perform most frequently scheduled maintenance tasks (including online backup, resizing, and file system changes) without interrupting data or system availability. VxFS also provides support for large file systems (up to 8 exabytes.)
VERITAS File System offers performance-enhancing features that are of particular interest in a database environment:
- VERITAS Quick I/O is a VxFS feature that improves the throughput for Oracle databases built on VERITAS File Systems. Quick I/O delivers raw device performance to databases run on VxFS, providing the administrative advantages of using file systems without the performance penalties.
- VERITAS Cached Quick I/O further enhances database performance by leveraging large system memory to selectively buffer the frequently accessed data.
- A feature of the Enterprise Edition, VxFS Storage Checkpoint technology lets you create a point-in-time image of a file system. Storage Checkpoints are treated like any other VxFS file system and can be created, mounted, unmounted, and removed with VxFS and VERITAS Storage Foundation for Oracle administrative utilities.
- VERITAS Extension for Oracle Disk Manager
VERITAS Extension for Oracle Disk Manager is a custom storage interface designed specifically for Oracle9i and 10g. Oracle Disk Manager allows Oracle9i and 10g to improve performance and manageability system bandwidth through an improved Application Programming Interface (API) that contains advanced kernel support for file I/O.
- VERITAS VxDBA Menu Utility
The VxDBA menu-driven utility allows you to perform various administrative tasks, including database monitoring, Storage Checkpoint and Storage Rollback administration, and file system space planning capabilities for Storage Checkpoints.
You can also use the graphical user interface or command line interface to perform these tasks.
- VERITAS Enterprise Administrator
VERITAS Enterprise Administrator (VEA) is the infrastructure that allows you to access VERITAS Storage Foundation for Oracle, VERITAS Volume Manager, and VERITAS File System information and features through the GUI.
- VERITAS NetBackup for Oracle Advanced BLI Agent (optional)
The VERITAS NetBackup for Oracle Advanced BLI Agent software supports Block-Level Incremental (BLI) Backup to reduce database down time, backup time, and backup volume, as well as CPU usage and network overhead. (Contact your Sales Representative for information about this optional product.)
An optional High Availability (HA) version of VERITAS Storage Foundation for Oracle Enterprise Edition, which includes VERITAS Cluster Server, is available for customers who have high system-availability requirements.
