CREATING A BACKUP SERVER

To define the attributes for a new Backup Server:

1. Accept the default values provided or modify those values to
   suit the system needs at your site.
2. Provide values for all required attributes (those marked with * ).
3. Provide values for additional functionality (optional).
4. Click Build Server! or click OK to create the new Backup Server.


BACKUP SERVER ATTRIBUTES

Related Adaptive Server Name  (Required)
----------------------------
Provide the name of one Adaptive Server that uses this 
Backup Server.

This field does not appear if the related Adaptive Server
is created in the same srvbuild session as Backup Server.
The Adaptive Server you are creating is used as the related
Adaptive Server. 


Adaptive Server SA User Name  (Required)
----------------------------
Provide the Sybase System Administator (SA) user name for the
related Adaptive Server, or accept the default value.

This field does not appear if the related Adaptive Server
is created in the same srvbuild session as Backup Server. 


Adaptive Server SA Password  (Required)
---------------------------
Provide the SA password for the related Adaptive Server.

This field does not appear if the related Adaptive Server is 
created in the same srvbuild session as Backup Server. 


Error Log Path  (Required)
--------------
The error log path points to a default error log file where specific
Backup Server messages are sent; for example, Open Server errors, errors 
for disconnected sessions, errors that halt Backup Server. 
   
The default path is $SYBASE/install/backup_server_name.log.


Tape Configuration File
----------------------- 
Backup Server reads this file, when a dump command is issued, to determine
the device type and the characteristics of the specified dump device. Having
access to this information, speeds up the dump process.

The default location is $SYBASE/backup_tape.cfg.


Language
--------
Specify the language you want Backup Server to use.

The default is us_english.

Valid language options depend on what Language Modules you downloaded
from the CD-ROM to your system.
 
 
Character set
-------------
Specify the character set you want Backup Server to use.

The default is iso_1. On HP-UX platforms, the default is Roman8.

Other valid options are: 
    * ascii_8, for use with unspecified 8-bit data
    * Roman8, Hewlett_Packard proprietary character set 
    * iso_1, ISO 8859-1 (Latin-1) - Western European 8-bit character set
    * cp850: Code Page 850 (Multilingual) character set
    * cp437: Code Page 437 (United States) character set
    * mac: Macintosh default character set for Western European locales


Maximum Number of Network Connections
-------------------------------------
This option specifies the number of total network connections if
dumping (backing up) or loading (restoring) a database over the 
network to a remote Backup Server.

The default value is 25. 

This option is not necessary if you are dumping to the default
Backup Server.


Maximum Number of Server Connections
------------------------------------
This option specifies the number of server connections for Backup Server.

The default value is 20.
  
Backup Server requires at least: 
    - two connections for each dump operation
    - one connection for each load operation 
    - one connection for volume change messages  

Allow a maximum of three times the number of expected concurrent dump and
load sessions.


Additional Command Line Parameters
----------------------------------
The additional command line options are used every time when this instance
of Backup Server is executed. It will set parameters that can not otherwise
be configured from this program.

Separate multiple parameters with a space. The parameters you specify
override the default values for your Sybase Backup Server.



Interfaces File Entry  (Required)
---------------------
The interfaces file is an "address book" containing
the network location for each server and client application. If the
network location is not in the interfaces file, servers and clients
can not communicate with each other.

The default location for the interfaces file is $SYBASE/interfaces.
An interfaces file entry contains:

    * Transport type
      The transport type, in conjunction with the port number, tells
      Backup Server where to listen for clients (in this case, 
      Adaptive Server).

      The drop-down list contains the network protocols supported by 
      Sybase on this platform. The default protocol is TCP.

    * Host name
      The host name is the name of the machine where you installed 
      Backup Server.

    * Port number
      If you did not change the default protocol, the port number displayed
      is the first available port address.

      If you select a protocol other than the default, the first available
      port number may or may not be supplied.


NOTES:
   
     The port number you specify cannot be used for any other purpose 
     on the machine where Backup Server is installed. 

     Add the port number you selected for Backup Server to the
     /etc/services file, and label the entry "Sybase specific services."
     (You must log in as "root" to modify /etc/services.)
     Making this entry is not required for the operating system to function 
     properly, but it may prevent others from using the port number.
