3.4 Environments
• Interval - The interval between retry attempts, expressed as a delta time. The default retry
interval is 15 minutes.
Each time a retry attempt is made, ABS generates a warning message. If you wish to see the
warning messages, select the warning option in the when attribute for notification.

3.4.9 Listing Option
3.4.10 Lock
3.4.11 Notification
For UNIX clients, ABS provides the option to either backup UNIX symbolic links only, or to
follow the UNIX symbolic links and backup up the data as well. The default is to backup the
symbolic links only (not the data).
In addition, ABS allows you to backup only the root file system (such as the disk the root directory
resides on) or an entire file system if the filesystem spans physical devices. The default is
nospan filesystems, which copies the root file system only.
Both attributes apply to data type UNIX_FILES only.
The listing option allows you to specify the type of listing generated for save and restore requests
using this environment. Specify one of the following options:
• NONE - Does not generate a listing file
• BRIEF - Generates a brief listing file
• FULL - Generates a detailed listing file
If not specified, NONE is the default option.
ABS allows you to specify what a save request should do when data usage conflicts occur by
means of the lock attribute. If you specify lock, ABS saves the data even if other applications
have the data locked for write access. If you specify nolock ABS does not save the data if other
applications have the data locked for write - this is the safer approach. If you specify lock, it is
possible that the data you save is inconsistent, as the other application may be writing to the file
during the actual save operation. Use lock with caution. The default is nolock.
ABS uses the notification attributes in the environment to determine who, how and under what
circumstances users are notified of ABS events during save and restore operations. ABS supports
notification using mail, OPCOM or both. You can specify up to 32 separate notification
options in each environment, using the following attributes:
• MAIL - Specifies one or more mail users to be notified on certain types of event; specify
one or more OpenVMS mail usernames (including node names as needed).
• OPCOM - Specifies one or more OPCOM classes to be notified on certain types of events -
specify one or more OpenVMS OPCOM classes (e.g. TAPES) to be notified - notification
will be directed to the (execution) node(s) specified in the save or restore request.
• TYPE - Indicates the level of information given. Select one of the following:
– BRIEF - Contains only basic information (default)
– NORMAL - Contains a moderate amount of information
– FULL - Contains the maximum amount of information
• WHEN - Indicates when the notification should occur. Choose one or more of the following:
– START - Sends notification at the start of a save or restore request
