Communications/Transactions Guide and Reference
Use the APPC Connection Spec - Settings window to change the attributes of
an APPC Connection Spec. These attributes represent a set of
protocol-specific communication parameters for an APPC conversation.
Use the Destination tab to specify the
transaction program (TP) and logical unit (LU) you want to connect to:
- Partner TP name
- In the Partner TP name field, type the name of the transaction
program (TP) you want to access on the remote host
- Partner LU alias
- From the Partner LU alias field, type the alias of the logical
unit (LU) you want to connect to on the remote host. This is the LU
through which the partner TP accesses the network.
- Fully qualified partner LU name
- In the Fully qualified partner LU name field, type the fully
qualified network name of the remote LU you want to connect to. You do
not need to specify a value in this field, if you provide a value in the
Partner LU Alias field.
- Userid
- In the Userid field, type the user ID you want to use to access
the remote system.
- Password
- In the Password field, type the password you want to use to
access the remote system.
- Security
- From the Security combo box, specify the level of APPC
conversation security to use (Same, Pgm, or
None).
Use the Conversation tab to specify parameters
that apply to the conversation:
- Local TP name
- In the Local TP name field, type the name you want to use to
identify the local program to the network. If you do not provide a
value in this field, VisualAge automatically generates a unique name at run
time.
- Local LU alias
- Use the Local LU alias combo box to specify the local logical
unit you want to connect to on the network. The LU aliases are defined
in your communication software configuration.
- Mode
- From the Mode combo box, specify the transmission mode to use
for the session. This mode can be any mode defined in the local
Communications Manager configuration. The default value is
#INTER.
- Sync level
- From the Sync level combo box, specify the level of APPC
synchronization to use for the conversation.
- Return control
- From the Return control combo box, specify when the local LU
should return control to the VisualAge application following an attempt to
open a connection.
Use the Data Attributes tab to specify program
initialization parameters and data handling options for a conversation:
- Code page
- In the Code page field, type the character code page used by
the remote system. The default code page is whatever the current code
page is for the system you are developing your application on.
- Buffer length
- In the Buffer length field, type the size of the memory buffer
VisualAge should allocate for the data sent to and received from the
server. For a remote external function call, the buffer size must be at
least as large as the total size of the record used by the function.
The default value for this field is 1024.
- Big endian
- Select Big endian to specify you want the partner to use the
bigEndian format. If you do not select Big endian, the
partner uses littleEndian format.
