If you want to take the easy way out, you can use the OEM Database Control tool to configure Flashback logging in your database using the following steps (assuming you are working in archivelog mode): 1. From the Database Home Page, click on the Maintenance tab. 2. Go to the Backup/Recovery section and click on Configure Recovery Settings. 3. Under the Flash Recovery Area section, specify the Flash Recovery Area Location and Flash Recovery Area Size. 4. Check the box next to Enable flashback logging for fast database point-in-time recovery, as shown in Figure 16-3.excel 2007 barcode generator free, microsoft excel barcode generator free, excel barcode generator free, barcode font for excel free, barcode fonts for excel, barcode add in for excel 2010, create barcodes in excel 2010 free, barcode font in excel 2010, excel barcode generator formula, download barcode font for excel 2010,

You can turn the Flashback Database feature off by issuing the ALTER DATABASE FLASHBACK OFF command. First, though, make sure you shut down the database and restart the database in the mount (or mount exclusive) mode before using this command. SQL> SHUTDOWN IMMEDIATE; SQL> STARTUP MOUNT; SQL> ALTER DATABASE FLASHBACK OFF;
When you disable the Flashback Database feature, Oracle deletes all Flashback Database logs in the flash recovery area.
If you want to use Flashback Database, but not for certain tablespaces, you can disable it using the ALTER TABLESPACE command: SQL> ALTER TABLESPACE users FLASHBACK OFF;
So far, it is sufficient to realize that a complete CTS type name contains the assembly name The type identity of managed types is much stronger than the type identity of native types Even if two types in different assemblies have the same namespace-qualified name, the runtime sees them as two different types This precise type identity concept is required to ensure NET s security features, but it can also cause trouble As a C++/CLI programmer, you must be aware of the different identity concepts for managed types If you include a header file with managed type declarations in your project, the compiler expects these types to be defined in your project, not in the library you would like to reference Including header files with declarations of managed types only makes sense if a managed type is used by source files from the same project that implements the managed type.
Note that two commands could be used. The head command on many UNIX systems normally displays only the first few lines of a file. The GNU version of the head command, however, has a -c option, as shown here. The -c switch specifies how many bytes or characters of data to display. The line of code that has been commented out uses the dd command to do the same thing; this command, with the bs (block size) set to 1 byte and a count of 1, is functionally the same as the head -c1 command. You will need only one of these lines. I ve shown both here because not all UNIX systems have the GNU version of head that has the -c switch, and I wanted to include an alternative command that can be used on both GNU and non-GNU systems. Once the Keypress variable has been assigned, you have to decide how to process it.
Once disabled, Oracle will not log any Flashback Database data for that tablespace. If you want to switch it back on again, you simply issue this command: SQL> ALTER TABLESPACE users FLASHBACK ON; Tablespace altered. SQL> As 4 explains, you can create a tablespace with the Flashback feature turned off by specifying the FLASHBACK OFF clause when creating the tablespace. By default, of course, Flashback is on.
With the Flashback Database feature enabled, a new background process, RVWR (Recovery Writer) is also enabled. This process copies, at infrequent intervals in order to reduce the I/O and CPU overhead, the before-image of each altered block in the data files from the memory buffer (flashback buffer) to the flashback database logs, which are stored in the flash recovery area. This flash recovery area is a dedicated area of disk storage for the retention of recovery-related components, such as these data file image copies, incremental backups, and archived redo logs.
To increase disk throughput, Oracle recommends the use of fast file systems and multiple disk spindles with small stripe sizes (128KB) for flash recovery areas.
The Flashback Database logs are similar to the traditional Oracle redo logs (both logs are written to from a buffer area) but with the big difference that there aren t any archived Flashback Database logs! Oracle stores all the Flashback Database logs in the flash recovery area.
