Optimizing your Oracle database data and metadata files
Veritas recommends that you do not keep the Oracle configuration files on a boot or a root disk. Use the following information to know more about how to move those files and optimize your Oracle installation.
Veritas takes disk snapshots. For better backup and recovery, you should optimize your Oracle database data and metadata files.
Each Oracle database instance has a control file. The control file contains information about managing the database for each transaction. For faster and efficient backup and recovery, Oracle recommends that you put the control file in the same file system as the database redo log file. If the database control file resides on the file system that is created on top of the boot disk or root disk, contact your database administrator to move the control file to the appropriate location.
For more information on control files and how to move them, contact your database administrator, or see the Oracle documentation.

After you use a snapshot to restore an application, do not perform any operations. Allow some time for Oracle to read new data and bring up the database. If the database does not come up, contact the database administrator to determine the cause of the problem.
