Host and storage requirements

Before using Database FlashSnap, ensure that the following requirements are

met:

■ All files are on VxFS file systems over VxVM volumes. Raw devices are not

supported.

■ Symbolic links to datafiles are not supported.

■ ORACLE_HOME is on a separate file system.

■ Archive logs are on a separate VxFS file system and are separate from the

VxFS file system containing Oracle data files or ORACLE_HOME.

■ The database does not contain BFILES and external tables.

■ Oracle datafiles, archive logs, redo logs, and control files are in a single or

multiple disk groups.

■ If your primary host is part of a cluster, it is not advised to use one of the nodes

in the cluster for off-host cloning.

■ The flash recovery area must be on a separate file system from ORACLE_HOME.

In addition, before attempting to use Database FlashSnap with an off-host

configuration, ensure that the following requirements are met:

■ The product versions installed on the primary and secondary hosts are the

same.
