Advanced Options

The Advanced Options dialog lets you set options associated with the creation of the DNA file.

The following options appear on the dialog:

Self-Extracting

Controls the creation of a self-extracting DNA file. You can also define how the self-extracting DNA file works on the destination machine by selecting from the following options:

Apply with Template

Identifies the template to use when the DNA file is applied to the destination. This template is included with the self-extracting file and lets an administrator define the functions available for a user to interact with on the destination machine. For example, they can define redirection of files, folders and filters, or let the user selectively apply items to the destination machine. Or, the administrator can choose to apply the entire file with no interaction by the end user.

Note: If you want to redirect items on the destination machine, you must define which template has the redirection defined in Apply with Template. Include the full path and file name for the template.

Apply with Options File

Identifies an alternative DMM Options file (.dox) that is used when the DNA file is applied to the destination machine. This options file is included with the self-extracting file and lets the administrator define the behavior of CA DMM and control the functions available for a user to interact with on the destination machine.

Note: You can specify to use the template file and options file when applying the DNA file to the destination machine. For example, defining both files could be especially important if you want to redirect files to a new location (specified in the template) and change the default location of any log files created (specified in the options file).

See Self-Extracting DNA Files and Redirection for details on defining a template and an options file to be used when applying a self-extracting DNA file.

Spanning

Supports the use of removable media, including CD-ROM. The media used is accessed efficiently and sequentially. Choose from the following options:

Automatic Spanning

Lets CA DMM manage the spanning of the DNA file across media.

Maximum File Size (Kb)

Specifies the size at which CA DMM requests additional media.

Data Protection

Specifies the level of protection for your data and provides you the option to encrypt the DNA (or SE) file. Encryption is done using the AES (Advanced Encryption Standard) 192 encryption algorithm.

Note: Selecting encryption helps ensure protection of all the data, though it may result in a considerably reduced performance of the migration tool.

You can select one of the following options:

Use no protection for data stored

Provides least or no protection for the DNA file.

Use password to deny access only (quickest)

Provides the option to specify a password to open a DNA file. The password is requested when you open a DNA file.

Use password to securely encrypt data (safe)

Provides the option to securely encrypt the DNA file. The password is requested when you try to open a DNA file or decrypt the encrypted data.

Note: To successfully complete the migration, provide a valid password prior to the migration.

Use FIPS compatible cryptography to encrypt data (safest)

Provides the option to securely encrypt the data using FIPS-compliant techniques. Click Enter Key Path to specify the path for storing the key.

Enter Password

Specifies a password to protect the DNA file. This option is enabled only when you select either the quickest or the safe option.

Enter Key Path

Specifies the path to store the key used for encryption. You must specify this key when you are opening or applying the DNA file.

Note: If you select the encryption option while capturing the settings and then use the CA Merger and Acquisition Tool to perform the migration, you need to make sure that you have entered the key path in the DMM Options file. If the tool does not find the key path in the DMM Options file, the tool stops the migration without displaying any error message. The reason is that the CA Merger and Acquisition Tool performs the migration in the silent mode and hence cannot prompt for the key path. However, the following error message is logged in the log file to specify that the migration has failed because of the non-availability of the key path in the DMM Options file:

Creation failed for "<DNA File Name>": No encryption key is available. A well-known encryption key was returned.
