Displays the extracted image against the color of your choice Displays the extracted image as solid white against a black background

This script will launch four channels, each of which will read a series of 10GB sections of datafile 16 Each channel will generate pieces (separate physical files) containing the backup of a section If the file is 200GB, there will be 20 such pieces, generated four at a time Without the SECTION SIZE keywords, the degree of parallelism would have been one (ie, serial) and one channel would have carried out the entire operation Exercise 15-3: Back Up Using Multiple Channels In this exercise, you will use a command block to launch multiple channels and parallelize a backup operation PART III 1 Connect to the database with the RMAN executable, using operating system authentication:

rman target /

Figure 5-13

2 In another window, connect to the database with SQL*Plus, using operating system authentication:

3 With SQL*Plus, investigate the number of sessions against the instance:

select username,program from v$session order by program;

You can continue to clean up the edges as necessary, or you can even go back and redraw the edges, refill the center, and then re-extract the image When you re satisfied with the object, click OK to formally extract the image to Photoshop, where the background pixels are erased and left transparent You can then place the object against the background of your choice

You will see that there are two sessions connected as user SYS using the RMAN executable as their user process: these are the default session and the polling session 4 At the RMAN prompt, create a command block by entering RUN followed by a series of commands within braces:

run { allocate channel d1 type disk; allocate channel d2 type disk; backup as compressed backupset database; }

5 While the backup is in progress, rerun the query from Step 3 You will see that there are now four RMAN sessions: the default session, the polling session, and two channel sessions 6 In the RMAN window, observe the progress of the backup; note how the files are divided between the two channels, each of which generates its own backup set

If you re working on the Background layer in a file, the layer is turned into a normal layer, and the background around the extracted image is erased to reveal the gray checkerboard pattern, as shown in Figure 5-14

In some environments there is a requirement for data to be encrypted This can be particularly important for backups, because they may be stored on removable media

over which the DBA has little or no control RMAN can encrypt backups, but there are two provisos: To create encrypted backups on disk, the Advanced Security Option must be enabled This is a separately licensed option that must be purchased on top of the Enterprise Edition database license To write encrypted backups directly to tape, the tape library must be accessed through the Oracle Secure Backup SBT interface, which is a separate product that must be licensed and configured for the tape library Encryption can be transparent or password based Transparent data encryption, which is the default, is based on the use of a wallet This is a file containing the keys used to encrypt and decrypt data, and is itself protected with a password However, the wallet can be configured to open automatically when needed The wallet must be available to the RMAN channel processes when creating or restoring backups; it is therefore most useful when backups will always be created and restored on the database on the same machine A password-encrypted backup can be restored anywhere, so long as the password is known Each backup uses a different, randomly generated key This key is itself encrypted with either the specified password, or the database master key stored in the wallet The available encryption algorithms are AES with keys of length 128 (the default), 192, or 256 bits To create a backup with password encryption, first set the algorithm and the password and then make the backup For example,

set encryption algorithm 'aes256' identified by pa55word; backup as compressed backupset database format '/u01/mnt/backups/orcl_encbkp';

Figure 5-14

Before attempting to restore using the backup, set the password again:

set decryption identified by pa55word;
