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[r]

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 into me[r]

Final Note on Oracle-Suggested Strategies
Taking a default backup strategy “off the shelf” has its benefits and its drawbacks. The benefits come from being able to “set and forget” the b[r]

Prepared for the Inevitable: Flashback Technology
When it comes to logical errors, media recovery should not be our first line of attack. It frequently is the line of attack, but this leads to massive outages. Typically, user error is not something that we can recover from, because the act[r]

Automatic Distribution of Backup Work Across Nodes
Since Oracle Database 10 g Release 2, RMAN can utilize information gleaned from Oracle’s Cluster Ready Services (CRS) to provide better RAC integration. Of most importance, you no longer have to configure a channel to[r]

You can use RMAN to take backups from the split mirror volume instead of from the production database itself.
Registering Split Mirror Copies with RMAN
If you are a dedicated RMAN user, then you probably understand the benefits that come from executing all recovery statements fro[r]

Don’t get attached to your test environment. Sometimes you need to just blow everything away and start over from scratch, particularly if you don’t have good maintenance habits. Eventually, your database will get to the point that it has had tablespaces dropped; has had re-created[r]

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

RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
This command ensures that RMAN retains three backups of each datafile: RMAN> CONFIGURE RETENTION POLICY TO REDUNDANCY 3;

Perhaps the most important aspect of a database administrator’s job is to ensure that the database does not lose data. The mechanisms of redo and undo ensure that it is absolutely impossible to corrupt the database no matter what the DBA does or does not do. After wor[r]

When the database is SHUTDOWN, all files are closed and the instance does not exist. In NOMOUNT mode, the instance has been built in memory (the SGA has been created and the background processes started, according to whatever is specified in its parameter file), but no connec[r]

For example, a level 0 backup of a database of 500GB that generates 50GB of redo per day might compress to 250GB. With a single T1, it might take over 50 hours to back up to S3, using most of the available network capacity. For this reason, you must carefully consider and test[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]

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[r]

The role of database administrator (DBA) has become a key to success in today’s highly complex database systems. The best DBAs work behind the scenes but are in the spotlight when critical issues arise. They plan, create, maintain, and ensure that the database is avail-[r]
