Table 5-2: Components of an interfaces file
Component
|
Value
|
|---|
servername
|
Name
of Adaptive Server or Backup Server. Requirements for a server name
are:
The name cannot be
more than 30 characters long.
The first character must be a letter (ASCII a through
z, A through Z).
The characters that follow must be letters, numbers,
or underscores (_).
|
retry_attempts (optional)
|
Number of times you want
the client to try to connect to a server after initial failure.
Default is 0.
|
delay_interval (optional)
|
Number of seconds between
connection attempts. Default is 0.
|
service_type
|
Type
of service defined by entry. Must be one of the following:
|
api
|
Application programming interface available
to the network.
|
protocol
|
Name of the network protocol.
Protocol types available are:
TCP/IP,
represented by the letters “tcp”
SPX,
represented by the letters “spx”
|
network
|
Name
of the network; not currently used by Adaptive Server. srvbuild enters “ether” as
a placeholder.
|
host
|
Network name or address
of server’s host machine.
For TCP/IP, use either the host name or Internet
address. Maximum size of entry is 32 bytes.
To determine
the host name of a machine, log in to that machine and enter:
/bin/hostname
For DECnet, use the node name. Maximum size of entry
is 6 bytes.
|
machine
|
Network name or address
of server’s host machine.
You can use either the host name or Internet address. Maximum
size of entry is 32 bytes.
To determine the host name of a machine, log in to that machine
and enter:
/bin/hostname
|
device
|
The network device endpoint.
For TCP networks, it varies
according to the vendor supplying the networking software. Check
the vendor-specific documentation for the name of the device. Your
network may provide multiple streams devices corresponding to different protocols
in the TCP protocol suite. Choose the TCP streams device. Common TCP
streams devices include /dev/tcp, /dev/ito,
and /dev/inet/tcp.
For the IPX protocol, the value is always /dev/nspx.
|
address for
a TCP protocol entry
|
Address consists of:
Address prefix, “\x” for
tli.
Network type, always 0002.
Port number converted to four digits, hexadecimal.
Must be between 1025 and 65535. Must be unique. Check the /etc/services file
on each machine on the network to see what port numbers are in use.
Enter the Adaptive Server port number in a new section of /etc/services labeled “Sybase
specific services.” You do not have to make this entry
for the operating system to function properly, but the presence
of the port number in the file may prevent other users from using
the port number.
IP network node address of the host machine converted
to eight digits, hexadecimal.
Trailing zeros, optional, 16 digits.
|
address for
an SPX protocol entry
|
Address consists of:
Address prefix, “\x” for
tli
Network address, 8 digits
Node address, 12 digits
Socket number, 4 digits
|
port/object
number
|
For TCP/IP networks, port is a unique port
number between 1025 and 65535. Check the /etc/services file
on each machine on the network to see what port numbers are in use.
Enter the Adaptive Server port number in a new section of /etc/services labeled “Sybase
specific services.” You do not have to make this entry
for the operating system to function properly, but the presence
of the port number in the file may prevent other users from using
that number.
For DECnet networks, object is
an object number between 128 and 253. The number must be unique
to the node on which the server is running.
|
port
|
A unique port number
between 1025 and 65535. Check the /etc/services file
on each machine on the network to see what port numbers are in use.
Enter the Adaptive Server port number in a new section of /etc/services labeled “Sybase specific
services”. You do not have to make this entry for the operating
system to function properly, but the presence of the port number
in the file may prevent other users from using that port number.
