presented in this chapter, keep in mind that we strongly recommend using Recovery Manager (RMAN) for performing backup and recovery and will explain why later. But for now, just know that we're off to a good start since we've answered our first question already![r]
Blackout Administration Blackouts suspend the collection of database monitoring data and the sending of alerts by Database Control. This enables you to perform scheduled maintenance on the database without receiving needless alerts and without skewing the monito[r]
8. Click Apply. A confirmation message appears. Example: Loading Data into a Table You can use Database Control to load data into a table. You can load data from a source file that is on your local computer—the one where your browser is running—or from a source file that is on the d[r]
The redo log stores a copy of the changes made to data. If a failure requires a datafile to be restored from backup, then the recent data changes that are missing from the restored datafile can be obtained from the redo log, so work is never lost. The redo log is used to recover a datab[r]
Cross-Checking Backups Cross-checking a backup synchronizes the physical reality of backups with their logical records in the RMAN repository. For example, if a backup on disk was deleted with an operating system command, then a cross-check detects this condition. After the cross-c[r]
Oracle Database is composed of the following elements: ■ The Oracle software that you install on your host computer ■ The database , which is a collection of physical files on one or more disks The database contains user data, metadata, and control st[r]
With enterprise users, identity preservation occurred, but just barely. Identity preservation means that you are able to preserve the identity of the end user from source application all the way to the database. You can then implement security and auditing controls on a user[r]
In Oracle Database 11g, you can configure scarce resources even better in a large-user environment by using the new database resident connection pooling (DRCP) feature. DRCP employs a pool of dedicated servers for servicing larger numbers of connections and<[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
8. Refresh the page until the dropped disks no longer appear in the disk group. Backing Up ASM-Managed Files Oracle recommends that you use Recovery Manager (RMAN) to back up files managed by ASM. See Chapter 9, "Performing Backup and Recovery" for th[r]
Oracle has focused development around a single source code model since 1983. While each database implementation includes some operating system–specific source code at very low levels in order to better leverage specific platforms, the inter- faces that users, developers, and<[r]
In SQL Server, the system databases, as well as master , msdb , and model , need to be backed up. Similarly, in Oracle, the control files, system datafiles, and parameter files for the Oracle database need to be backed up. In SQL Server, the tempdb database<[r]
There are opportunities to use the newer syntax and save time, but the old way also continues to work. The old way is more widely understood and portable. Set Operators Beginning with Oracle 10 g, Release 1, the database now supports set operators for[r]
If you want to edit or remove sensitive data from the diagnostic information, enclose additional user files (such as application configuration files or scripts), or perform other customizations before uploading, you must use the custom packaging process. See Oracle Database Adminis[r]
Statement Tuning and Workload Tuning Note that both the SQL Tuning Advisor and the SQL Access Advisor provide index creation recommendations. The SQL Tuning Advisor recommends creation of indexes only when it anticipates exceptional performance gains for the SQL statement being tun[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, unco[r]
