Moves one page back in the wizard.
It is available on all but the first page of the wizard.
Moves one page forward in the wizard, except on the last page of the wizard where it is unavailable. This button may also be disabled on some pages until all required information has been entered by the user.
Starts the process that creates a database partition based on your specifications. (Available when you specify all the required input.)
Cancels any changes you have made to this wizard and closes the wizard.
Specifies that you want to perform a full database backup.
Specifies that you want to back up only selected table spaces. Table spaces that are not selected at the time of the backup operation will not be in the same state as those that are selected.
Specifies the names of table spaces that you have not selected to backup.
Specifies the type of data that is stored in each table space.
Indicates the current state of the table space.
Specifies the name of table spaces that you have selected to backup.
Specifies the type of data that is stored in each table space.
Indicates the current state of the table space.
Moves the selected item from the Available list to the Selected list.
Moves all of the items from the Available list to the Selected list.
Moves the selected item from the Selected list to the Available list.
Moves all of the items from the Selected list to the Available list.
Select the type of media on which the backup image will reside.
Specify one or more locations in which to store the backup image.
To prevent a media failure from destroying a database and your ability to rebuild it, you should keep the database backup image, the database logs, and the database itself (table spaces) on different devices.
Opens a window so that you can add items to the list.
Opens a window so that you can make changes to the selected item.
Removes the selected item from the list.
Specifies that the backup will be compressed.
The number of sessions to open, from 1 - 999.
The number of sessions to open, from 1 - 999.
Specifies options to be used for the backup operation. The string will be passed to the vendor support library.
Specify the absolute file path of the user DLL.
Opens a window from which you can view available items and select one.
Specifies the names of partitions that you have not selected to back up.
Shows the host name of each available partition.
Shows the logical port assigned to each available partition.
Shows the switch name of each available partition, if applicable. The switch name is used for communication between hosts.
Shows the order in which the groups will be backed up, starting at 1. If items have been grouped, they will have the same order number.
Specifies the names of partitions that you have selected to back up.
Shows the host name of each selected partition.
Shows the logical port assigned to each selected partition.
Shows the switch name of each selected partition, if applicable. The switch name is used for communication between hosts.
Select to run the backup serially on all partitions.
-->Moves the selected item from the Available list to the Selected list.
Moves all of the items from the Available list to the Selected list.
Moves the selected item from the Selected list to the Available list.
Moves all of the items from the Selected list to the Available list.
Moves the selected object up one position in the list box.
Moves the selected object down one position in the list box.
Click to specify that you want the selected partitions to be a group. Partitions within the same group will be backed up in parallel. If you have many partitions, you can put them into separate groups to be backed up serially.
Click to specify that you want to remove the grouping of the database partitions.
Specifies a full backup image. Note that full database backups are not always the best approach when dealing with large databases, because the storage requirements for multiple copies of such databases are enormous. However, a full database backup is recommended for disaster recovery, so you should take full backups regularly. Having full backups will also speed up the recovery time required when restoring a database.
Specifies a cumulative (incremental) backup image. An incremental backup image is a copy of all database data that has changed since the most recent successful, full backup operation.
Note: You are required to have at least one full database image in order to use this option.
Specifies a non-cumulative (delta) backup image. A delta backup image is a copy of all database data that has changed since the most recent successful backup operation of any type.
Note: You are required to have at least one full database image in order to use this option.
Specifies that the database can be backed up while users or applications are connected. Database performance can be decreased. The backup process may take longer.
If it is online, other applications or processes can continue to connect to the database as well as read and modify data while the backup task is running. However, online backups are supported only if roll-forward recovery is enabled.
Specifies that the backup image should include the range of log files required to restore and roll forward this image to some consistent point in time.
Specifies that no users or applications can be connected to the database during the backup process. The backup process may be faster.
If the backup is performed offline, only the backup task can be connected to the database. The implication of offline backup is that the rest of your organization cannot connect to the database while the backup task is running.
Select to quiesce the database. When a database is quiesced, all users are forced off the database and all units of work are rolled back. Users are not allowed to reconnect to the database until the database is unquiesced. Note: There are exceptions. Users with SYSADM, SYSMAINT, SYSCTRL or quiesce_connect authority can still connect. This option can be used only when you are performing an offline backup.
Specifies that you want to regulate the performance impact of this maintenance utility, so that it can be run concurrently with production periods.
Opens a window where you can increase or decrease the resources used for running this utility.
Specifies the number of buffer manipulators that are to be spawned during the backup operation. To optimize performance you may want the number of buffer manipulators to be equal to the number of backup images being used. Note that the higher the number you specify, the more memory required. If you require more memory than is available, the backup operation will fail.
Specify the number of buffers that are used for the backup operation. The default is 2. The valid range is from 2 - 16 384. If you use multiple buffers and I/O channels, you should use at least twice as many buffers as channels to ensure that the channels do not have to wait for data.
Specify the size of each buffer in 4 KB pages. The ideal backup buffer size is a multiple of the table space extent size. If you have multiple table spaces with different extent sizes, specify a value that is a multiple of the largest extent size. The range is from 8 to 524 288. The default for tape device is 8 to ensure that the value is smaller then the tape buffer size, otherwise the backup will be corrupt. The default for all other media is 1024.
Resets the Parallelism, Number of Buffers and Size of Each Buffer fields to the values recommended by the wizard.
