ORACLE DATABASE 10G RMAN BACKUP RECOVERY BOOK

backups, and thus your database, are recoverable. First, we will look at the verify and check logical options of the restore command. Then, we will look at the validate backupset command.

When you allocate the tape channel for restore, RMAN creates a server process at the target database. This channel then calls sbtinit() to initialize the media manager software. This is identical to the initialization that would take place for a backup: the MML file is loaded[r]

Protecting Users from Users
Much of the thought put into backups and recovery is to protect the system from hardware issues or even disasters, but you also need to consider what damage people can do. Developers, users, and DBAs use the database environment for development, testing,[r]

Because of the many caveats associated with deploying backups over the Internet to S3, any organization contemplating it should rigorously test both backup and recovery performance before embarking on a large-scale migration to this architecture.
Regardless of database size,[r]

If you’re doing a full restore of the database, and you have already verified that you have a good backup, the restore performs faster if the existing datafiles are not there to be overwritten. If possible, rename the files (if space permits) or remove the files before doing a comple[r]

Backup and Recovery Issues
This is an area where the DBA cannot work in isolation. The amount of downtime and data loss that an organization can stand is a matter for the business analysts, not the DBA. The business analysts in conjunction with the end users will determine the requ[r]

For the retention policy, the setting of the recovery window sets the number of days between the current time and the earliest point of recovery, which doesn’t matter if there are incremental or full backups in between. But those backups will be marked obsolete when they hit the number[r]

Curriculum Development: This course was designed by Donald K. Burleson, author of more than 30 database books, Burleson was chosen by Oracle Press to write five authorized editions, including Oracle High-Performance SQL tuning. Burleson has over a decade of real- world DB[r]

From Sam
Writing a book is always a team effort, although this fact isn’t easily evident to the reader, and I’m grateful to the wonderful Apress team that helped make this book a reality. I owe an enor- mous debt of gratitude to the brilliant contributions of lead editor Jonathan Gen[r]

Background Information
This book is purposefully designed as a follow-up to Effective Oracle Database 10g Security By Design , published by McGraw-Hill Professional in 2004. In that book, author David Knox, who serves as lead author for this book,[r]

Several components are critical to this goal, and all of them are covered in depth after

Planning Space Usage and Location for the Flash Recovery Area
You should place the flash recovery area on a separate disk from the working set of database files. Otherwise, the disk becomes a single point of failure for your database. The amount of disk space to allocat[r]

Database cloning can provide an excellent way to test version upgrades, new application rollouts, and even bug patches. Cloning can also be used to prepare reporting databases that are kept separate from transaction processing databases. In these ways, database backups can be put to[r]

Datafiles
The previous section explained what happens to Oracle datafiles if a mirror split takes place without any preparation: the split volume copies of the files are left in a fuzzy, unusable state. This is precisely the same predicament you run into if you simply take a copy of an onl[r]

And that is all you’re going to get from us on the subject, except to say this: you can still use manually built raw partitions on a shared disk array to arrange your RAC datafiles and log files. So, if you desire, you do not need a cluster file system or ASM. You just need raw, uncooked, shared[r]

Flashback Drop allows you to “undrop” database objects. No longer will you have users desperate for the entire database to be restored to a point in the past because they thought they were on the DEV instance instead of PROD.
There’s nothing all that dramatic about how Flashback Dr[r]

s the complexity of production enterprise environments grows with each passing year, we DBAs are finding the same complexity creeping into our test environments. For example, in Oracle9 i RMAN Backup & Recovery, the test environment was seemingly complex for us[r]

Cold Backups
Cold backups are the simplest type of backup operation you can perform. Cold backups are performed with the database completely shut down in a consistent manner. Once that is done, all database files should be backed up to disk or tape. Once the file copies are co[r]
