Combination time consists of an absolute time value plus or minus a delta time value. The delta time portion of the combination time must always be preceded by a plus or minus sign.
[absolute time] +/- [delta time] |
When you specify a combination time, you can omit the absolute time. If you omit the absolute time, the delta time is an offset from the current date and time. If you specify any part of the absolute time, the defaults are those specified in the description of absolute times. However, it is recommended that you specify the date-time information as completely as possible.
The variable fields and default fields for absolute and delta times are the same as those described in the preceding sections. Several samples of combination time formats are listed in Table 2-7.
| Specification | Meaning |
|---|---|
| +5 | Current time plus 5 hours. The absolute time portion is omitted so it defaults to the current date and time. |
| +:5 | Current time plus 5 minutes. The absolute time is omitted so it defaults to the current date and time. |
| 15-APR:+:5 | 12:05 AM on April 15 of the current year. The absolute time specification (before the colon) defaults to midnight on April 15 of the current year. The plus sign indicates a positive offset. |
| TOMORROW+1-00:00 | Tomorrow plus 1 day. |
| -:5 | Current time minus 5 minutes. The absolute time specification is omitted so it defaults to the current date and time. |
| -1 | Current time minus 1 hour. The minus sign indicates a negative offset. The one indicates hours since it is not followed by a dash. |
| -1-00 | Current time minus 1 day. The minus sign indicates a negative offset. The dash between the 1 and 00 indicates that this is a number of days. |
| 15-APR:-00:10 | 11:50 PM on April 14 of the current year. |
2.12.2 Wildcards
Several different wildcards are recognized in MEDIA forms.
They can be used in file names, media names and user name
specifications. The various wildcards are:
The above wildcards can be combined into a very complex search string.
The MOTIF Work Center makes all media management, backup and file vaulting tasks easier and more productive by offering the user a versatile menu-based MOTIF interface. This greatly simplifies daily system management tasks by providing handy point and click operations to all levels of user.
The first thing you will notice about the three interfaces of the MOTIF Work Center is that they appear similar in many respects. Each of the interfaces for MEDIA, BCKMGR and VAULT are similarly laid out in that they provide the user with a listing of available media (for MEDIA), backup jobs (for BCKMGR) and vaulted files (for VAULT). The interfaces also utilize similar selection and filtering options.
The MEDIA interface lets you perform virtually any media management task. From tracking location and contents to changing access privileges and organizing media into pools, the MOTIF Work Center is the perfect tool for the job. The media and a variety of information about it is always in view so you know what media you are working with.
The BCKMGR interface is ideal for managing the submission of your time critical jobs. It lets you do all the important backup manager procedures. A variety of submission options are always in your reach including execution queues, commands to be executed and a multitude of time scheduling options. A list of jobs is always visible so you know just what jobs are being modified and/or submitted.
The VAULT interface can be used to execute all vault saveset
tasks. It's the perfect tool to find and restore files that you need to
retrieve from off-line storage. Files are displayed with the valuable
information needed to make an educated determination of which version
number and media to use for a restoration.
3.1 MOTIF Interface basics
The following sections describe aspects of the MOTIF interface used in
the MOTIF Work Center .
3.1.1 Mouse interaction
This section describes the use of a mouse within job group windows and in conjunction with the MOTIF Work Center . It is assumed that the user is on a workstation that features a three button mouse as shown in Figure 3-1.
Figure 3-1 Mouse Buttons
Though the mouse you are using has three buttons (MB1, MB2 and MB3), we will only be using two. The left button (MB1) will be referred to as left clicking and the right button (MB3) will be referred to as right clicking. However, these buttons may be configured in the opposite way. The middle button is not used in the MOTIF Work Center .
For instance, the statement "click on the first media in the list"
means put the cursor over the first media and click with MB1.
3.1.2 Common controls
The MOTIF interface used by the MOTIF Work Center uses a number of
controls that occur throughout the program. Users should be aware of
these CONTROLS before using the MOTIF Work Center . They are described
in the following sections.
3.1.2.1 Pull down menus
The pull down menu is one of the most common interface tools in all
graphical user interfaces. The MOTIF Work Center uses menu bars for the
MEDIA, BCKMGR and VAULT modules. Selecting
an item in a pull down menu involves first clicking on the menu in the
menu bar, holding down the mouse button, dragging the cursor to the
desired menu item and releasing the button.
3.1.2.2 Common dialog box buttons
Dialog boxes in the MOTIF Work Center use a common convention for
accepting or cancelling the input into the form. Most users familiar
with graphical user interfaces will be aquainted with this standard.
The most commonly used buttons are described in the following list:
[Apply] The Apply button is used to accept the data entered into the form without exiting the form. This is an efficient way to make multiple changes without exiting the dialog box.
[OK] - The OK button is the acceptance button. This means any changes to the form are accepted and will be saved as modified. This button is selected when the correct information has been entered.
[Cancel] - The Cancel button is used to decline the data entered into the form or just to exit the form if no changes are needed. Often it is necessary to view a form without making changes to the data in the form. In this case you would choose cancel after making the changes.
[Default] - The default button brings any default values into the form fields. The form data may then be changed or saved as is.
[Help] - The Help button will bring up a help screen for the form that is currently being edited. This will help the user understand the data needed in the fields.
[Print] - Brings up the print controls dialog and gives the user the option to print the data designated.
3.1.2.3 Form fields
Form fields are used to enter data into forms. In forms that contain
pre-existing data, the data may be deleted or overwritten. Though most
fields are filled manually there are several other ways to enter data
into fields in the forms. This includes the [Compose...] and
[Choice...] buttons described in the following sections.
3.1.2.4 Compose... buttons
The [Compose...] button is used to fill in specific
information in a field, such as a date. The data is composed using
sliders and buttons that create the string in the correct format
required for the field. For instance, a date field requires the date to
be entered in the following format.
Feb 15 1995 08:48:43.8 |
By selecting the [Compose...] button beside the field,
the date may be created using a number of controls.
As the figure illustrates, the date may be composed by moving slider controls to the correct setting or by selecting a button such as [Yesterday], [Today], [Now] and [Tommorow] and adjusting from there.
3.1.2.5 Choices... buttons
The [Choices...] button is used when only a limited list of
data is valid for a particular field. After the [Choices...]
button is selected,
the input may be created by selecting a member of the list.
3.1.2.6 Radio buttons
Radio buttons allow a yes/no selection of data to be made. This is
often used when selecting whether a piece of data or flag needs to be
turned on or off. Some radio buttons are tied to more than one
selection so that a selection must be made between them.
Some examples of radio buttons are shown below.
Drop down lists are used to select among a number of data selections. Left click on the list which causes the other selections to be displayed. Next, drag down to the desired selection and release. The resulting selection will be used.
An example of a drop down list is shown below.
If you are familiar with MEDIA, you already know the vast scope of functionality that can be utilized in managing your media. The MOTIF Work Center adds a whole new dimension of simplicity to your media operations by placing all of MEDIA's functions in an easy to use MOTIF interface. Tasks are easier to access, making your work more productive.
The MOTIF Work Center can be used to perform a wide variety of media management tasks. The initial display will include a list of all media that are in your MEDIA database. The list can be altered to include or exclude certain media as well as display other aspects of the media. From this list you can choose the operation to perform on one or more of those media entries. Some features of the MOTIF Work Center are described in the following sections.
This chapter will describe the media operations that can be performed
using the MOTIF Work Center .
4.1 The MEDIA interface
The MEDIA interface is made up of the media selection fields, the media list and several controls for customizing and displaying the media list. See Figure 4-1. The procedure for performing media operations on one or more media is to:
Techniques for selecting more than one media are explained in Section 4.1.1.2. |
There are several methods for selecting which media are to be displayed in the MOTIF Work Center . This allows a user to limit the DISPLAYed media in the list according to a criteria that makes sense for the situation. Perhaps you need to only select from the list of media in the available pool or owned by a certain user.
The most obvious way to limit the list's scope is to designate Include or Exclude criteria from the Media selection section of the main screen. The resulting list would be limited to those media that were excluded (or included) by the media name entered in those fields.
As in all search criteria operations, the filtered list is not displayed until the Filter button is selected. |
Another way of selecting a limited list of media using other criterion is by selecting the Search controls... button on the main screen. A dialog box display will give the user the ability to limit the list by Type, Density, Pool etc.
The media you select from the media list will all be affected by the
operation you perform. It is therefore important that you are sure all
selected media are correct. The methods for selecting media are
described in detail in the following sections.
4.1.1.1 Selecting a single medium
In order to select a single medium, place the cursor over the desired medium and click with the left mouse button. See Figure 4-2.
Figure 4-2 Select a single medium
4.1.1.2 Selecting more than one medium
You can select more than one specific media by using the
[Ctrl] and [Shift] keys.
In order to select more than one media that are not in adjacent rows in the list, depress the [Ctrl] key and click on the desired media with the left mouse button.
In order to select more than one media that are listed together in the media list, depress the [Shift] key and click on the first medium in the series. Next, click on the last medium in the series. All media between will be selected. See Figure 4-3.
Figure 4-3 Selecting multiple media
4.1.1.3 Selecting and deselecting all media
To select all media in the media list, click the [Select
all] button on the main window. All media in the list will be
highlighted. Individual lines can then be deselected using the method
described in Section 4.1.1.2.
To deselect all selected media, click the [Clear selections] button on the main window. All highlighted media will be deselected.
