Adding a Remote HP 3000 System Definition
Add the definition of a remote HP 3000 system to the data dictionary at
the Add Remote 3000 System (A3) screen, shown below. Using this screen
is the first step in defining your data on the remote HP 3000.
The host system does not need to be defined.
Table 3-1 describes the fields on the Add Remote HP 3000 System screen.
DBA Capabilities.
You can add a definition of a remote HP 3000 system to the data
dictionary only if you are the primary DBA.

Table 3-1. Add Remote HP 3000 System Screen Fields
-------------------------------------------------------------------------------------------------------------
| | |
| Field | Description |
| | |
-------------------------------------------------------------------------------------------------------------
| | |
| Remote System | Name used to identify the remote system in the rest of the |
| | Administrator Utility. It need not be identical to the |
| | device class name of the remote system. The syntax follows |
| | MPE file naming conventions. |
| | |
-------------------------------------------------------------------------------------------------------------
| | |
| Node | For an NS connection, the node name of the remote HP 3000 |
| | system, qualified, if necessary, by the domain and the |
| | organization (for example, NSNODE.DOMAIN.ORG). |
| | |
-------------------------------------------------------------------------------------------------------------
| | |
| User | MPE user name for remote system logon. The specified user |
| | must have a home group defined in the specified account. |
| | Unless database or file access is relaxed, this home group |
| | must contain the databases or files that will be accessed |
| | from this remote HP 3000 system. |
| | |
-------------------------------------------------------------------------------------------------------------
| | |
| User Password | Logon password for specified MPE user. If the user has no |
| | password, leave this field blank. The password conforms to |
| | MPE syntax for user passwords. |
| | |
-------------------------------------------------------------------------------------------------------------
| | |
| Account | Account name for remote system logon. |
| | |
-------------------------------------------------------------------------------------------------------------
| | |
| Account Password | Logon password for specified account. If the account has |
| | no password, leave this field blank. |
| | |
-------------------------------------------------------------------------------------------------------------
To Add a Remote HP 3000 System Definition:.
1. Go to the Add Remote HP 3000 System screen by typing A3 in the Go
to screen field of any menu, or by choosing Add HP 3000 f1 at the
Remote HP 3000 System Menu.
2. Type in the remote system name, the node name (qualified if
necessary), the logon user and account, and the user and account
passwords (if any).
_________________________________________________________________
NOTE When you leave either password field blank, Access Server
defines the remote system with a blank password in the data
dictionary.
To avoid software problems with having the user's server
process prompted for a required password when none has been
supplied, Access Server will use an uppercase A as the
password whenever it logs on to the remote HP 3000 in this
situation.
When you try to add or change such an HP 3000 system
definition, you will be told either that a password was
supplied when none was needed or that an incorrect password
was supplied. In the first case, please ignore the message;
all is well. In the second case, correct the password and
try again to add or change the definition.
_________________________________________________________________
3. To add the definition, press Enter.
The host attempts to initiate a session on the remote system.
If the remote logon succeeds, the remote welcome message is
displayed (if there is one). The remote system definition is
added to the data dictionary.
If the remote logon fails, a message appears indicating the cause
of the failure. If the cause seems to be something you typed, the
field containing the error is highlighted. Correct the
information and press Enter to try again to add the remote system.
4. When the screen clears, you can add another remote system.
5. To leave this screen, choose Done f8. This returns you to the
Remote HP 3000 System Menu. From there, you can go to another
screen or exit the utility.
Once you have successfully added the remote system definition to the data
dictionary, use the Add IMAGE Database (AIMD) or Add File (AF) screens to
configure remote databases or files. Then use the Add IMAGE Table
(AIMT), Add File Table (AFT), and Add View Table (AVT) screens to
configure IMAGE tables, file tables, and view tables from these databases
and files.
Maintaining Security.
To maintain security on the remote HP 3000 system's databases and files,
you need to define access to the same system several times with different
MPE logons. Define a new remote HP 3000 system for each unique logon
that accesses the group and account in which a particular remote database
or file is located. In this way, Access Server will log the user onto
the system into the group that has access to the database or file under
normal (non-released) MPE and IMAGE security.
Here's how to proceed:
1. Use the same identifier in the Node field for several remote
system definitions.
2. Use different names in each Remote System field, and different
logons.
3. At the Add IMAGE Database screen (AIMD) or Add File screen (AF),
use the appropriate name in the Remote System field to configure
each database or file. This establishes the host session in the
group and account for the database or file.
Changing a Remote HP 3000 System Definition
Change a remote HP 3000 system definition already in the data dictionary
at the Change Remote HP 3000 System (C3) screen. This screen displays
the current definition of the remote system you specify, in the same
format as the Add Remote HP 3000 System screen.
You can change all fields except the Remote System name. (For
information about these fields, see "Add," above.)
To change the Remote System name, you must delete the entry (along with
any databases defined for it) and add a new entry. (See "Delete,"
below.)
DBA Capabilities.
You can change a remote HP 3000 system definition only if you are the
primary DBA.
Impact on PC Users.
If you have "released" your databases or files, changing the remote logon
should have no effect on your users. The same databases or files should
be accessible through Access Server as before.
But if, for example, your previous logon account was ACCT1, where
database DB1 was secured, then changing your logon account to ACCT2 would
make database DB1 inaccessible to Access Server users.
Releasing DB1 is one way to solve this problem. (For a discussion of how
to release databases and files, see "Data Access Across Groups or
Accounts" in Chapter 2.)
Alternatively, you can use the Add Remote HP 3000 System screen to define
one remote system several times with different remote system names and
logons. (For instructions, see "Maintaining Security," above.)
To Change a Remote HP 3000 System Definition:.
1. Go to the Change Remote HP 3000 System screen by typing C3 in the
Go to screen field of any menu, or by choosing Change HP 3000 f2
at the Remote HP 3000 System Menu.
2. Type the remote system name and press Enter.
If an entry exists for this remote system, the rest of the fields
used to add a definition appear with the current definitions
filled in.
3. Type in any changes to the Node, User, User Password, Account, and
Account Password fields.
If you decide to leave the remote definition unchanged, choose
Cancel Changes f8. The screen will clear and you can specify
another remote system to change or return to the Remote HP 3000
System Menu.
_________________________________________________________________
NOTE When you leave either password field blank, Access Server
defines the remote system with a blank password in the data
dictionary.
To avoid software problems with having the user's server
process prompted for a required password when none has been
supplied, Access Server will use an uppercase A as the
password whenever it logs on to the remote HP 3000 in this
situation.
When you try to add or change such an HP 3000 system
definition, you will be told either that a password was
supplied when none was needed or that an incorrect password
was supplied. In the first case, please ignore the message;
all is well. In the second case, correct the password and
try again to add or change the definition.
_________________________________________________________________
4. To put the changes into effect, press Enter.
The host attempts to initiate a session on the remote system.
If the attempt succeeds, the welcome message (if any) from the
remote system appears. The existing entry for the remote system
is updated.
If the attempt fails, an error message appears and the incorrect
field is highlighted. Type in the correct information and press
Enter, or choose Cancel Changes f8 to leave the remote system
definition unchanged.
5. When the screen clears, you can change another remote system
definition.
6. To leave this screen, choose Done f8. This returns you to the
Remote HP 3000 System Menu. From there, you can go to another
screen or exit the utility.
Deleting a Remote HP 3000 System Definition
Delete an unwanted remote HP 3000 system definition at the Delete Remote
HP 3000 System (D3) screen.
Impact on PC Users.
Deleting a remote system definition has no effect on a user currently
accessing a configured table whose data derives from the remote HP 3000's
databases or files. The user is working from a copy of the data created
before the remote system and its database or file definitions were
deleted.
DBA Capabilities.
You can delete a definition of a remote HP 3000 system to the data
dictionary only if you are the primary DBA.
To Delete a Remote HP 3000 System Definition:.
NOTE Before deleting a remote HP 3000 system definition, you must delete
all databases and files defined for that system using the Delete
IMAGE Database (DIMD) and Delete File (DF) screens. (See "Deleting
an IMAGE Database Definition" and "Deleting a File Definition" in
Chapter 4.)
1. Go to the Delete Remote HP 3000 System screen by typing D3 in the
Go to screen field of any menu, or by choosing Delete HP 3000 f3
at the Remote HP 3000 System Menu.
2. Type the name of the remote system whose definition you want to
delete.
3. Press Enter.
The Administrator Utility looks through the data dictionary for
the remote system name and any databases or files configured for
it.
If there are no databases or files defined for the remote system,
it is deleted from the dictionary.
If you did not first delete such databases or files, an error
message appears and the deletion does not take place.
4. When the screen clears, you can delete another system.
5. To leave this screen, choose Done f8. This returns you to the
Remote HP 3000 System Menu. From there, you can go to another
screen or exit the utility.
Examining Remote HP 3000 System Information
Examine information about remote HP 3000 systems at the Show Remote HP
3000 System (S3) screen and at the List Remote HP 3000 Systems (L3)
screen.
These screens provide two different ways to examine the definitions of
remote systems currently defined in the data dictionary:
* Display the definition of a specific remote system (Show), or
* Display a list of all defined remote systems (List)
Whether you Show or List depends on why you are referencing the
information. The two screens are shown on the next page.
DBA Capabilities.
You can display both a definition of a specific remote system and a list
of all defined remote systems if you are the primary DBA. You can display
only a list of all defined remote systems if you are a secondary DBA.
