VERITAS Software Used in Point-In-Time Copy Scenarios

This guide provides a number of example scenarios that illustrate how to implement point-in-time

copy solutions. The following table shows the VERITAS products that may be used with a

VERITAS FlashSnap license to provide the required functionality in different environments:

VERITAS Storage Foundation for databases is required if you want to use the VERITAS Quick

I/O, VERITAS Extension for Oracle Disk Manager (ODM), VERITAS QuickLog

, Storage

Checkpoints and management interface features to enhance database performance and

manageability.

The VERITAS Clustering Functionality for VxVM and VERITAS Cluster File System features of

VERITAS Storage Foundation for Cluster File System and Cluster File System HA allow you to

share data within a cluster. The HA version uses VERITAS Cluster Server to allow you to

configure automated application and storage failover to provide continuous availability of service.

Note The Cached Quick I/O and QuickLog features are not supported for use with VERITAS

Cluster File System. The Cached Quick I/O, Quick I/O and QuickLog features are not

supported at all on the Linux platform.

The database server products mentioned in this document may not be supported on certain

operating system platforms.

The following non-cluster specific components are used in the sample scenarios:

◆ VERITAS Volume Manager (VxVM) is a disk management subsystem that supports disk

striping, disk mirroring, and simplified disk management for improved data availability and

superior performance. The FlashSnap license enables the use of the Persistent FastResync and

Disk Group Split/Join features of VxVM.

◆ VERITAS File System (VxFS) is 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
